GENERAL INFORMATION This gas-fired combination water heater’s design is certified by CSA International under the American National Standard Z21.10.1 - (as indicated on the rating plate) and CSA 4.1-M - (as indicated on the rating plate). This water heater must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1-Latest Edition) and/or in Canada CAN/CGA B149 Installation Codes (Latest Editions).
General Information continued- 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.
Installation (Locating The Water Heater) continued- Note: For California installation this water heater must be braced, anchored, or strapped to avoid falling or moving during an earthquake. See instructions for correct installation procedures. Instructions may be obtained from California Office of the State Architect, 400 P Street, Sacramento, CA 95814. Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors.
Installation (Locating The Water Heater) continued- 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 the detection of the gas. • 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.
Installation (Minimum Clearances) continued- Minimum Clearances WARNING Failure to adhere to these installation and operating instructions may create a hazard to life and property and will nullify the warranty.

Installation (Venting) continued- IMPORTANT All of the Venting connections must be leak checked with a soap solution upon initial start up of the water heater. Any leaks shall be repaired before continuing operation of the water heater. NOTE: ABS or CPVC pipes may be substituted for PVC pipe. Do not mix ABS and PVC pipe in the same installation. THROUGH THE WALL VENTING: Cut a 3 1/2 in. (8.9 cm) diameter hole in the wall at the point where the vent connector is going to pass through the wall.
Installation (Venting) continued- THROUGH THE ROOF VENTING: (VERTICAL VENTING) Cut the necessary holes through the roof and ceiling and install the vent connector as shown in Figure 4A. Make sure that the installation meets the local codes and/or The National Fuel Gas Code ANSI Z223.1 (Latest Edition) or CGA/CAN B149 Installation Code. Installations having long vertical runs through attics or long horizontal runs through unheated crawl spaces may accumulate condensate.
Installation (Venting) continued- THROUGH THE WALL VENTING WITH LOW GROUND CLEARANCE: When venting cannot exit through the wall at a height greater than or equal to 12” (30.5 cm) from the ground, then the installation shall be modified as shown below (see Figure 5). Refer to Table 3 for maximum venting lengths using 3” (7.6 cm) PVC or Table 4 for maximum lengths using 4” (10.1 cm) PVC.

Combustion Air Supply WARNING Liquefied petroleum gases/propane gas are heavier than air and will remain at floor level if there is a leak. 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 YOU SMELL GAS: • Do not try to light any appliance. • Do not touch any electric switch; do not use any telephone in your building.
Installation (Combustion Air Supply) continued- All Air From Inside the Building: The confined space shall be provided with two permanent openings communicating directly with an additional room(s) of sufficient volume so that the combined volume of all spaces meets the criteria for an unconfined space. The total input of all gas utilization equipment installed in the combined space shall be considered in making this determination.
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.
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, ANS Z21.
Installation (Water Connections) continued- WARNING Hydrogen 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.
Gas Connections The gas supply lines must meet all requirements of the National Fuel Gas Code (ANSI Z223.1-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 supply 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 type.
become wet, they must be thoroughly dried before attempting to operate the water heater.
Electrical Connections All electrical wiring and connections shall be in accordance with the National Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical Code C22.1 (latest edition) and any local codes which may apply. The water heater shall be electrically grounded. If a flexible line cord and plug is permitted by local code, then provide a (3) three wire grounding type receptacle within 6 feet (1.9 m) of the water heater and use the flexible cord provided.

GENERAL OPERATION WARNING Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system, and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
General Operation continued- 27
Thermostat Adjustment CAUTION Before adjusting thermostat(s), turn off power supply to the water heater. The thermostat dial is adjusted to its lowest temperature position when shipped from the factory. When adjusting the thermostat, it should be remembered that lower temperature settings are more energy efficient. The thermostat cover, on the right side of the gas valve, shall be removed when the thermostat is adjusted.
Burner Flame Check Cast Iron Burner: At the time of installation and at periodic intervals (not more than 6 months), a visual check of the main burner and pilot flames should be made to determine if they are burning properly. For ideal operation, the gas and air must be properly proportioned. The proper air-gas mixture is obtained by adjusting the air shutter on the mixer face of the main burner (See Figure 8).
MAINTENANCE WARNING Water heaters are heat producing appliances. To avoid damage or injury there shall be no materials stored against the water heater or vent-air intake system, and proper care shall be taken to avoid unnecessary contact (especially by children) with the water heater and vent-air intake system.
Maintenance continued- 5. 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.
