3 Consumer Informa tion This water heater is design-certified by CSA International as a Category I, direct vented water heater which takes its combustion air from the outside of the structure and exhausts all products of combustion to the outside of the structure. This water heater must be installed according to all local and state codes or, in the[...]

4 This water heater design has been tested by CSA International and complies with ANSI Z21.10.1, Section 2.35 Flammable Vapors Resistance. Therefore this water heater does not need to be installed 18 inches above the floor unless specifically required by state or local codes. The water heater must be located or protected to avoid physical damage by[...]

Important: The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time. Also any external plumbing leak, in[...]

6 The Vent terminal is HOT when the water heater is in operation. Do not touch the vent terminal or place any object where contact with the vent terminal may occur. A protective louvered wall or fence is recommended when the hot vent cap is low enough to be touched accidentally (see Figure 5). A Vent guard kit (Kit # 6907245) may be ordered by cont[...]

9 Import ant: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to corrosive elements in the atmosphere is excluded from warranty coverage. Vent Pipe System This is a direct vent water heater which draws its combustion air from outside of the structure and exhausts all products of combustion to the outsid[...]

10 9. Position and fasten the inner wall plate to the inside wall using an appropriate fastener for the specific wall construction. Apply silicone sealant between the inner wall plate and the inside wall. 10. Make certain the 5 telescoping pipe has been fully engaged onto the 5 inch elbow. Drill two 1/8 holes 180° apart at the junction of th[...]

11 THROUGH THE ROOF VENTING* 1. Center the heater directly under the roof opening. This vent system must be installed vertically only. 2. All the pipes needed to assemble the vent are included in the kit. Do not add to the length of the vent system. The total height is limited to 15 feet on a 50-gallon heater (See Figure 11). The 40-gallon heater i[...]

Water System Piping Piping Inst alla tion Piping, fittings, and valves should be installed according to the installation drawing (Figure 12). If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure of the water heater. [...]

Please note the following: DO NOT install this water heater with iron piping. The system should be installed only with piping that is suitable for potable (drinkable) water such as copper, CPVC, or polybutylene. DO NOT use PVC water piping. DO NOT use any pumps, valves, or fittings that are not compatible with potable water. DO NOT use valves that [...]

For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked T & P RELIEF VALVE (see Figure 14). This valve must be design certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or mater[...]

15 Solar Installation If this water heater is used as a solar storage hea ter or as a backup for the solar system, the water supply temperatures to the water heater tank may be in excess of 120°F. A tempering valve or other temperature limiting valve must be installed in the water supply line to limit the supply temperature to 120°F. Note : Solar[...]

Wa ter Hea ter Loca tion · Centrally located with the water piping system. Located as close to the gas piping and vent pipe system as possible. · Located indoors and in a vertical position. Protected from freezing temperatures. · Proper clearances from combustible surfaces maintained and not installed directly on a carpeted floor. · Provisions [...]

17 OPERATING YOUR WATER HEATER Lighting Instructions Read and understand these directions thoroughly before attempting to light or re-light the pilot. Make sure the tank is completely filled with water before lighting the pilot. Check the data plate near the gas valve control/thermostat for the correct gas. Do not use this water heater with any gas[...]

L.P.G. (Bottled Propane) Models Liquefied Petroleum Gas is over 50% heavier than air and in the occurrence of a leak in the system, the gas will settle on the floor level. Basements, crawl spaces, skirted areas under mobile homes (even when ventilated), closets and areas below ground level will serve as pockets for the accumulation of gas. Before l[...]

Burner Flames Inspect the burner flames through the viewport and compare them to the drawings in Figure 16. A properly operating burner should produce a soft blue flame. Blue tips with yellow inner cones are satisfactory. The tips of the flame may have a slight yellow tint. The flame should not be all yellow or have a sharp blue-orange color. Conta[...]

A thermocouple is used to determine if a pilot flame is present and will shut off the gas supply to the main burner and the pilot burner if the flame is absent. A high temperature limit switch or ECO (Energy Cut Off) in the tank is used to shut off the unit if the water temperature exceeds 180°F (83°C). The ECO is a single use switch and requires[...]

Explosion Hazard If the temperature and pressure relief valve is dripping or leaking, have a licensed plumber correct the problem. Do not plug valve. Do not remove valve. Failure to follow these instructions can result in death, or explosion. MAINTENANCE OF YOUR WATER HEATER Draining and Flushing It is recommended that the tank be drained and flush[...]
