GENERAL INFORMATION 


This water heater must be installed in accordance with The Federal 
Manufactured Home Construction And Safetv Standard (H.U.D. Title 24, Part 
3280.707d2) or CAN/CSA Z240 MH series, mobile home. In the absence of 
such a standard, the water heater should be installed in accordance with the 
Standard For Mobile Homes (ANSI/NFPA NO. 501-B1977). 


The warranty for this water heater is in effect only when the water heater is 
installed, adjusted, and operated in accordance with these Installation and 
Operating Instructions. The manufacturer will not be liable for any damage 
resulting from alteration and/or failure to comply with these instructions. 


This water heater is of the closed combustion type (direct venting) where all the 
combustion air is supplied from the outdoors through the air intake and all 
combusted gas products are vented directly to the outside by means of the roof 
jack. No draft diverter (vent hood) is required for this water heater. 


Underwriters Laboratories, Inc. has tested a representative sample of this water 
heater design for its safety of operation. The UL listing of this water heater 
includes the field installation of the following components: roof jack, air intake 
tube, and heater tie down materials. These components for field installation 
may have been shipped with this heater and must be installed according to 
these instructions (see figure 1). No other components are approved for use 
with this water heater. 


This water heater has been designed and certified for the purpose of heating 
potable water. The installation and use of this water heater for any purpose 
other than the heating of potable water may cause damage to the water heater, 
create a hazardous condition, and nullify the warranty. 


A CAUTION 


Incorrect operation of this appliance mav create a hazard to life 
and propertv and will nullifv the warrantv. 








Do not use this appliance if anv part has been submerged in water. Vou should 
contact the plumbing professional who installed the water heater to inspect the 
appliance and to replace anv part of the control svstem including the 
combination gas control which has been submerged in water. 


IMPORTANT 


Before proceeding, please inspect the water heater and components for 
possible damage. DO NOT install any damaged components. If 
damage is evident then please contact the supplier where the water 
heater was purchased or the manufacturer listed on the rating plate for

General Information continued- 


This water heater has been manufactured for operation at altitudes from sea 
level to 2000 feet (610m) (unless otherwise specified on the water heater). 

For use of this appliance at an elevation greater than 2000 feet (610m), contact 
the dealer or manufacturer listed on the rating plate for information on anv 
necessarv modification. Uncorrected operation of this appliance mav create a 
hazard to life and propertv. 


A DANGER 





Do not store or use gasoline or other flammable, combustible, or 
corrosive vapors and liquids in the vicinity of this or any other 
appliance. 


Make sure to check the rating plate and combination gas control on the water 
heater to be certain that the type of gas being supplied corresponds with the 
marking on the rating plate and combination gas control. 


A sacrificial anode is used to extend tank life. The removal of this anode, for 
any reason, will nullify the warranty. In areas where water is unusually active, 
an odor may occur at the hot water faucet due to a reaction between the 
sacrificial anode and the impurities in the water. If this should happen, an 
alternative anode may be purchased from the supplier that installed this water 
heater. This will minimize the odor while protecting the tank. Additionally, the 
water heater should be flushed with appropriate dissolvers to eliminate any 
bacteria. 

INSTALLATION 
Locating the Water Heater 


This water heater MUST NOT be installed in any location where gasoline or 
flammable vapors are likely to be present, unless the installation is such to 
eliminate the probable ignition of gasoline or flammable vapors. 


The location of this water heater is of the utmost importance. Before installing 
this water heater, read the Installation section of these instructions. DO NOT 
locate the water heater where water lines could be subjected to freezing 
temperatures. Make sure the cold water pipes are not located directly 
above the gas control so that condensate during humid weather does not 
drip on the controls. 


A WARNING 


Water heaters are heat producing appliances. To avoid damage or 
injury there must be no materials stored against the water heater or 
vent-air intake system and proper care must be taken to avoid 
unnecessary contact (especially by children) with the water heater and 
vent-air intake components. UNDER NO CIRCUMSTANCES MAY 
FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT 
THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER 
HEATER, VENT-AIR INTAKE SYSTEM OR IN ANY LOCATION FROM 
WHICH FUMES COULD REACH THE WATER HEATER OR VENT- 
AIR INTAKE SYSTEM. 





Installation (Locating The Water Heater) continued- 


Water heater corrosion and component failure can be caused by the heating 
and breakdown of airborne chemical vapors. Examples of some typical 
compounds that are potentially corrosive are: spray can propellants, cleaning 
solvents, refrigerator and air conditioning refrigerants, swimming pool 
chemicals, calcium and sodium chloride, waxes and process chemicals. These 
materials are corrosive at very low concentration levels with little or no odor to 
reveal their presence. NOTE: DAMAGE TO THE WATER HEATER CAUSED 
BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED BY THE 
WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE 
HAS OR WILL OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE 
COMPOUNDS IN THE VICINITY OF THE WATER HEATER. 


For exact venting specifications, please consult the Venting section of these 
Installation and Operating Instructions. It is recommended that a minimum 
clearance of 4 inches (70.2 cm) be provided on the side of the water heater for 
servicing and maintenance of the combination temperature and pressure relief 
valve. 


A WARNING 
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE 
NOT CERTAIN OF THE FOLLOWING: 
¢ Liquefied petroleum gases/propane gas and natural gas have an 
odorant added by the gas supplier that aids in detection of the gas. 
e Most people recognize this odor as a “sulfur” or “rotten egg” smell. 
¢ Other conditions, such as “odorant fade” can cause the odorant to 
diminish in intensity, or “fade”, and not be as readily detectable. 
e If you have a diminished sense of smell, or are in any way unsure of 
the presence of gas, immediately contact your gas supplier from a 
neighbor's telephone. 
e Gas detectors are available. Contact your gas supplier or plumbing 
professional for more information. 


A WARNING 


Liquefied petroleum gases/propane gases are heavier than air and will 
remain at floor level if there is aleak. Basements, crawl spaces, closets 
and areas below ground level will serve as pockets for accumulation of 
leaking gas. Before lighting, smell all around the appliance area for 
gas. Be sure to smell next to the floor. 


IF VOU SMELL GAS: 





° Do not try to light any appliance. 

. Do not touch anv electric switch; do not use anv telephone in 
vour building. 

° Immediatelv call vour gas supplier from a neighbor's 
telephone. Follow the gas supplier’s instructions. 

° If you cannot reach your gas supplier, call the fire department. 


DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS CORRECTED!

Installation (Locating The Water Heater) continued- 
This water heater MUST be installed indoors out of the wind and weather. 


This water heater must be located in an area where leakage of the tank, water 
line connections, or the combination temperature and pressure relief valve will 
not result in damage to the area adjacent to the water heater or to lower floors 
of the structure. When such locations cannot be avoided, a suitable drain pan 
must be installed under the water heater (Refer to drain pan installation section 
for more information.). The drain pan must have a minimum length and width 
of atleast 4 in. (10.2 cm) greater than the diameter of the water heater and 
must not restrict proper combustion air flow to the water heater. The drain pan, 
as described above, can be purchased from vour plumbing professional. The 
drain pan must be piped to an adequate drain. The piping must be at least 3/4 
inch (1.9 cm) in diameter and pitched for proper drainage. 


To comply with NSF requirements this water heater is to be: 
a) Sealed to the floor with sealant, in a smooth and easily cleanable way, 
or 
b) Installed with an optional leg kit that includes legs and/or extensions 
that provide a minimum clearance of 6” beneath the water heater. 


Note: For California installation this water heater must be braced, 
anchored, or strapped to avoid falling or moving during an earthquake.

Combustion Air Supplv 


All combustion air must be supplied from outdoors by one of the following 
installation methods and as illustrated in Figure 5. The flow of combustion and 
ventilating air must not be obstructed. Adequate air must be supplied for 
combustion and ventilation. An insufficient supply of air will cause recirculation 
of combustion products resulting in air contamination that may be hazardous to 
life. Such a condition often will result in a yellow, luminous burner flame, 
causing carboning or sooting of the combustion chamber, burners and flue 
tubes with possible damage to the heater. 


AIR INTAKE INSTALLATION - 3” (7.6cm) diameter telescoping air intake and 
leg enclosure are required to supply fresh air to the water heater for 
combustion kit P/N 239-37025-01 for 30 gallon (773.5L) water heaters and 239- 
37025-02 for 40 gallon (151.4L) water heaters. Note: When a mobile home is 
tightly skirted, an air inlet opening in the skirting must be provided. The 
opening shall have a minimum free area of at least 9 in? (22.9cm’). If the 
opening is screened or covered with a louver, the total free area must be 
at least 9 in? (22.9em'). The following steps must be followed for proper 
installation of these air supplv components: (Refer to Figure 5).

Combustion air supply continued- 


1. After selecting the proper location for the water heater, cut a 4” (10.2cm) 
diameter hole through the floor and all other layers of flooring and 
sheathing directly beneath the front center of the water heater. 

2. Insert the air intake into the 4” (10.2cm) diameter hole and fasten to the 
floor with the screws provided. 

3. Adjust the air intake so the lower tube extends below the underside 
sheathing and secure with the screws provided. THE BOTTOM OF THE 
AIR INTAKE MUST BE AT LEAST 12” (30.5cm) ABOVE THE 
GROUND LEVEL. 

4. Seal the openings around the air intake and underside sheathing to resist 
the entrance of rodents. 

5. Position the water heater so it is centered above the air intake. (Note: 
The water heater should also be centered with the openings in the 
roof and ceiling to allow for correct assembly of the roof jack to the 
flue tube.) 


The water heater is to be secured in place using the supplied sheet metal 
strapping and screws. Fasten the base of the water heater to the floor using 
the screws provided. The perforated metal strapping must be fastened to the 
top of the water heater and to the adjacent walls with the screws provided.

Venting 


A WARNING 





The vent system must be installed properly. Failure to properly install 
the vent system could result in property damage, personal injury, or 
death. 





Make certain the flue baffle is in place and centered in the flue tube. Cut a 7 
1/4 inch (18.5cm) diameter hole in the ceiling and roof directly above the flue of 
the water heater. Center the water heater beneath the 7 1/4 inch (18.5cm) 
diameter hole in the roof and ceiling for proper alignment of the flue tube and 
roof jack vent. Apply non-hardening mastic on the roof, around the previously 
cut hole, to form a weather seal with the flashing of the gas vent roof jack 
assembly. Note: Only the roof jacks listed in Figure 5 can be used on this 
water heater. Insert the 3 inch (7.62 cm) vent connector extension (shipped 
telescoped) into the gas vent roof jack assembly and down onto the flue pipe 
extruding from the top of the water heater. Fasten the 3 inch (7.62 cm) vent 
connector to the flue pipe using the 3 inch (7.62 cm) clamp provided. After all

Water Connections 


NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE 
MAIN WATER SUPPLY VALVE. 


After shutting off the main water supply, open a faucet to relieve the water line 
pressure to prevent any water from leaking out of the pipes while making the 
water connections to the water heater. After the pressure has been relieved, 
close the faucet. The COLD water inlet and HOT water outlet are identified on 
the top of the water heater. The fittings at the cold water inlet and hot water 
outlet are dielectric waterway fittings with 3/4” NPT male thread. Make the 
proper plumbing connections between the water heater and the plumbing 
system to the house. Install a shut-off valve in the cold water supply line. 


A CAUTION 


If sweat fittings are to be used, DO NOT apply heat to the nipples on top 
of the water heater. Sweat the tubing to the adapter before fitting the 
adapter to the water connections. It is imperative that heat is not 
applied to the nipples containing a plastic liner. 





A WARNING 
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4” 
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE 
THE MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT 
FROM EXCESSIVE TEMPERATURE AND PRESSURES. 














12 


Water connections continued- 


If this water heater is installed in a closed water supplv svstem, such as the one having a 
back-flow preventer in the cold water supplv, provisions shall be made to control thermal 
expansion. DO NOT operate this water heater in a closed svstem without provisions for 

controlling thermal expansion. Your water supplier or local plumbing inspector should be 
contacted on how to control this situation. 


After installation of the water lines, open the main water supply valve and fill the water 
heater. While the water heater is filling, open several hot water faucets to allow air to 
escape from the water system. When a steady stream of water flows through the 
faucets, close them and check all water connections for possible leaks. NEVER 
OPERATE THE WATER HEATER WITHOUT FIRST BEING CERTAIN IT IS FILLED 
WITH WATER. 


A WARNING 


For protection against excessive temperatures and pressure, install temperature 
and pressure protective equipment required by local codes, but not less than a 
combination temperature and pressure relief valve certified by a nationally 
recognized testing laboratory that maintains periodic inspection of production of 
listed equipment or materials as meeting the requirements of the Standard for 
Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply 
Systems, ANSI 221.22 or the Standard CAN1-4.4. Temperature and Pressure 
and the Standard CAN1-4.4, Temperature, Pressure, Temperature and 
Pressure Relief Valves and Vacuum Relief Valves. The combination 
temperature and pressure relief valve shall be marked with a maximum set 
pressure not to exceed the maximum working pressure of the water heater. The 
combination temperature and pressure relief valve shall also have an hourly 
rated temperature steam BTU discharge capacity not less than the hourly rating 
of the water heater. 


Install the combination temperature and pressure relief valve into the opening 
provided and marked for this purpose on the water heater. 


Note: Some models may already be equipped or supplied with a combination 
temperature and pressure relief valve. Verify that the combination temperature 
and pressure relief valve complies with local codes. If the combination 
temperature and pressure relief valve does not comply with local codes, replace 
it with one that does. Follow the installation instructions above on this page. 


Install a discharge line so that water discharged from the combination 
temperature and pressure relief valve will exit within six (6) inches (15.2 cm) 
above, or any distance below the structural floor and cannot contact any live 
electrical part. The discharge line is to be installed to allow for complete 
drainage of both the combination temperature and pressure relief valve and the 
discharge line. The discharge opening must not be subjected to blockage or 
freezing. DO NOT thread, plug or cap the discharge line. It is recommended 
that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of 
the water heater for servicing and maintenance of the combination temperature 
and pressure relief valve. 


Do not place a valve between the combination temperature and pressure relief 
valve and the tank. 











13 


Water Connections continued- 


A WARNING 


Hvdrogen gas can be produced in an operating water heater that has not had 
water drawn from the tank for a long period of time (generally two weeks or 
more). Hydrogen gas is extremely flammable. To prevent the possibility of 
injury under these conditions, we recommend the hot water faucet to be open 
for several minutes at the kitchen sink before you use any electrical appliance, 
which is connected to the hot water system. If hydrogen is present, there will be 
an unusual sound such as air escaping through the pipes as hot water begins to 
flow. Do not smoke or have open flame near the faucet at the time it is open. 











This water heater can deliver scalding temperature water at any faucet in the 
system. Be careful whenever using hot water to avoid scalding injury. Certain 
appliances such as dishwashers and automatic clothes washers may require 
increased temperature water. By setting the thermostat on this water heater to 
obtain the increased temperature water required by these appliances, the 
potential for scald injury increases. To protect against injury, you should install 
an ASSE approved mixing valve in the water system. This valve will reduce 
point of discharge temperature by mixing cold and hot water in branch supply 
lines. Such valves are available from the manufacturer of this water heater or a 
local plumbing supplier. Please consult with a plumbing professional. 


Water temperature over 125°F 
À DA N e E EI can cause severe burns 
instantiv or death from scalds. 


Children, disabled and elderly 
are at highest risk of being 
scalded. 


Review this instruction manual 
before setting temperature 
at water heater. 


Feel water before bathing or 
showering. 


Temperature limiting valves are 
available.

Gas Connections 


The gas supplv lines must meet all requirements of the National Fuel Gas Code 
(ANSI 2223.1-Latest Edition), or in Canada CAN/CGA B149.1 Natural Gas 
Installation Code (Latest Edition) or CAN/CGA B149.2 Propane Installation Code 
(Latest Edition). 


The minimum permissible gas supplv pressure for the purpose of input adjustment 
is one (1.0) inch (0.25 kPa) water column above the operating manifold pressure. 
See the rating plate and gas valve for the manifold pressure and gas tvpe. The 
maximum permissible gas supply pressure is fourteen (14.0) inches (3.5 kPa) water 
column for natural gas and liquefied petroleum gases/propane gas. 


1. 


Connect this water heater only to the type of gas (Natural or Propane gas) as 
shown on the rating plate. Use clean black iron pipe or equivalent material 
approved by local codes and ordinances. (Dirt and scale from the pipe can 
enter the gas valve and cause it to malfunction). The inlet gas line must have a 
minimum length of three (3) inches (7.6 cm) drip leg (sediment trap) installed as 
close to the water heater’s gas valve as possible. A ground joint union must be 
installed as close to the water heater as possible in the gas supply line feeding 
the water heater to permit servicing of the water heater. Compounds used on 
the threaded joints of the gas piping must be resistant to the action of liquefied 
petroleum gases/propane gas. DO NOT apply pipe dope to the gas valve inlet 
and make certain that no pipe dope has become lodged in the inlet screen of 
the gas valve. Extreme care must be taken to ensure no pipe dope enters the 
gas valve. Avoid excessive torque when tightening the gas supply line to the 
gas valve. Excessive torque may result in cracking of the gas valve housing 
and could create a gas leak. When tightening gas supply line to L.P. control, it 
is recommended to hold the inlet body of the control securely with an adequate 
wrench. The suggested maximum torque is 31.5 ft. Ibs. (4.4 kg-m). 


A WARNING 


The manufacturer of this water heater will not be liable for any damage or 
injury caused as a result of a cracked gas inlet as a result of excessive 
torque. 








This water heater and its gas connection must be leak tested before placing the 
water heater in operation. Check for gas leaks with a soap and water solution 
and a brush or a commercial leak detector fluid. NEVER USE A MATCH OR 
OPEN FLAME FOR TESTING! 


A CAUTION 


The water heater and individual shutoff valve must be disconnected from the 
gas supply piping system during any pressure testing of the system at test 
pressures in excess of 1/2 psi (3.5 kPa). The water heater must be isolated 
from the gas supply piping system by closing its manual shutoff valve during any 
pressure testing of the gas supply system at test pressures equal to or less than 
1/2 psi (3.5 kPa). The supply line must be capped when not connected to the 
water heater. 








While checking for leaks care must be taken to prevent solution from 
contacting the electrical connections at the control. If electrical connections at 
the control become wet, they must be thoroughly dried before attempting to 
operate the water heater.

General Operation continued- 


A DANGER 


Hotter water increases the risk of scald injurv. Scalding mav occur 
within five (5) seconds at a temperature setting of 140 F (60 C). To 
protect against hot water injury, install an ASSE approved mixing valve 
in the water system. This valve will reduce point of discharge 
temperature by mixing cold and hot water in branch water lines. A 
licensed plumbing professional or local plumbing authority should be 
consulted. 


Note: This water heater is equipped with an energy cut out device to 
prevent overheating. Should overheating occur or the gas supply fail to 
shut off, turn off the manual gas control valve to the appliance and call a 
qualified service technician. 


Note: Whenever the water heater is filled with cold water, condensate 
will form on the cool tank surface and drops of water will fall on the hot 
burner and combustion chamber surfaces producing a “sizzling” noise. 
Condensation is normal and does not indicate a leak. It will disappear 
when the tank becomes heated. 

Burner Flame Check 

Steel Burner: These models are equipped with self adjusting air mixture and 
do not have an adjustable air shutter (See Figure 12). At periodic intervals, a 
visual check of the main burner and pilot flames should be made to determine if 
they are burning properly. The main burner flame should light smoothly from 
the pilot.

MAINTENANCE 





IMPORTANT 


The water heater should be inspected at a minimum annually by a qualified 
service technician for damaged components and/or joints not sealed. DO NOT 
operate this water heater if any part is found damaged or if any joint is found not 
sealed. 


The following maintenance should be performed by a qualified service 
technician at the minimum periodic intervals suggested below. In some 
installations, the maintenance interval may be more frequent depending on the 
amount of use and the operating conditions of the water heater. 


24 


Maintenance Continued- 
Regular inspection and maintenance of the water heater and vent-air intake 
svstem will help to insure safe and reliable operation. 


1. 


Annually check the operation of the thermostat. 


2. The flow of combustion and ventilation air MUST NOT be restricted. Clear 


3. 


4. 


the combustion air openings of any dirt, dust, or other restrictions. 


A WARNING | 


The ventilation air system may be HOT. 
At all times keep the water heater area clear and free from combustible 
materials, gasoline and other flammable vapors and liquids. 
Bi-annually conduct a visual check of the main and pilot burner flames to 
determine that they are burning properly. See Burner Flame Check 
section. 
Annually remove the inner door and main burner assembly to clean orifices 
and related parts of any dirt or other foreign material. Inspect the burner 
ports for obstructions or debris and clean with a wire brush as needed. 
Wire brush and/or vacuum clean the combustion chamber as needed to 
remove scale deposits and debris. NOTE: It is imperative for proper 
operation of the water heater that the inner door be replaced in the original 
location. 


A WARNING 


When lifting the lever of the combination temperature and 
pressure relief valve, hot water will be released under pressure. 
Be careful that any released water does not result in bodily injury 
or property damage. 





. At least once a year, check the combination temperature and pressure relief 


valve to insure that the valve has not become encrusted with lime. Lift the 
lever at the lever at the top of the valve several times until the valve seats 
properly without leaking and operates freely. 


. Monthly drain off a gallon of water to remove silt and sediment. 


AAWARNING THIS WATER MAY BE HOT. 


If the combination temperature and pressure relief valve on the appliance 
discharges periodically, this may be due to thermal expansion in a closed 
water supply system. Contact the water supplier or local plumbing 
inspector on how to correct this situation. Do not plug the combination 
temperature and pressure relief valve outlet. 

A combination sacrificial anode rod/hot water outlet nipple has been 
installed to extend tank life. The anode rod should be inspected 
periodically and replaced when necessary to prolong tank life. Water 
conditions in your area will influence the time interval for inspection and 
replacement of the anode rod. 


25 


Maintenance Continued- 


Contact the plumbing professional that installed the water heater or the 
manufacturer listed on the rating plate for anode replacement information. 

The use of a water softener mav increase the speed of consumption. More 
frequent inspection of the anode is needed when using softened (or phosphate 
treated) water. 


The vent svstem must be inspected at least once a vear to ensure against 
leakage of exhaust products. 


A CAUTION 
FOR VOUR SAFETV, DO NOT ATTEMPT REPAIR OF COMBINATION 
GAS CONTROL, BURNERS OR GAS PIPING. REFER REPAIRS TO A 
QUALIFIED SERVICE TECHNICIAN. 


Contact vour supplier or plumbing professional for replacement parts or contact 
the companv at the address given on the rating plate of the water heater. 








Provide the part name, model and serial numbers of the water heater when 
ordering parts.
