GENERAL INFORMATION This gas-fired 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- 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.
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. This installation must allow access to the front of the water heater and adequate clearance must be provided for servicing and operating this water heater. The water heater may be installed on either a combustible or noncombustible floor.

Venting continued- NOTICE For installations in Canada, field supplied plastic vent piping must comply with CAN/CGA B149.1 (latest edition) and be certified to ULC S636. The supplied vent connector and vent termination are certified as part of the water heater. Venting System Condensation Condensate formation does not occur in all installations of power vented heaters, but should be protected against on installations where condensation can form in the venting system.
Venting continued- 2. In order to prevent condensate from draining back into the blower (vertical or horizontal runs), a drain tee and condensate trap can be installed in the horizontal vent as close as practical to the blower vent connection (see Figure 3). The condensate disposal tube should be installed to drain any accumulated condensate away from the water heater and to a suitable drain.
Venting continued- This water heater is a power direct vented appliance and is designed to intake and exhaust the products of combustion through 3” (7.6 cm) or 4” (10.2 cm) diameter Schedule 40 PVC pipe to the outdoors. This water heater may intake and exhaust either through the wall or vertically through the roof. Use a 3” (7.6 cm) to 4” (10.2 cm) reducer to connect to the intake and outlet when using 4” (10.2 cm) PVC. Table 2 lists the maximum intake and exhaust lengths for this water heater using 3” (7.
Venting continued- EXAMPLE: The exhaust has two 90° elbows and the intake has four 90° elbows. The total feet of straight pipe on the exhaust is 15 ft. (4.6 m) and the total feet of straight pipe on the intake is 20 ft (6.1 m). Figure 4 six 90° elbows x 5 ft. each = 30 ft Total straight pipe = 11 ft+3 ft+1 ft+3 ft+9 ft+6 ft+2 ft= 35 ft Total equivalent feet = 65 ft Total six 90° elbows x 1.5 m each = 9.0m straight pipe=3.4m+.91m+.31m+.91m+2.7m+1.8m+.61m = 10.6m Total equivalent meters = 19.

Venting continued- When venting through the wall, the exhaust terminal must exit the structure at a minimum of 16” (40.6 cm) from either side, or any location above the intake terminal. The exhaust terminal must not be located below the intake terminal for any reason (See Figure 8). Figure 8 THROUGH THE ROOF VENTING: (VERTICAL VENTING) Cut the necessary holes through the roof and ceiling and install the vent connector as shown in Figure 9.
Venting continued- HIGH ALTITUDE INSTALLATIONS FOR ELEVATIONS OVER 2,000 FEET (914.5 m) ABOVE SEA LEVEL The capacity of the induced draft blower declines with increasing altitude due to a reduction in the air density. In order to assure safe and reliable performance of the water heater, the following guidelines must be followed. Refer to the venting tables below for maximum distances for the altitudes in your location.
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.
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.
Electrical Connections All electrical wiring and connections must 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 must 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.

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 system.
General Operation (Lighting and Shutdown Instructions) continued- Lighting and Shutdown Instructions 29
Thermostat Adjustment CAUTION Before adjusting thermostat(s), turn off power supply to the water heater. The thermostat dial is adjusted to approximately 120°F when shipped from the factory. When adjusting the thermostat, it should be remembered that lower temperature settings are more energy efficient. The thermostat cover, to the right of the gas valve, must 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 12).
MAINTENANCE 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 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.
