FILLING THE WATER HEATERVent dampers must bear evidence of certification as complying withthe current edition of the American National Standard ANSI Z21.66CGA 6.14 (covering electrically and mechanically actuated ventdampers). Before installation of any vent damper, consult the localgas utility for further information.To insure proper venting of this gas-fired water heater, the correctvent pipe diameter must be utilized. Any additions or deletions of othergas appliances on a common vent with this water heater may adverselyaffect the operation of the water heater. Consult your gas supplier ifany such changes are planned.Never use this water heater unless it is completely full of water. Toprevent damage to the tank, the tank must be filled with water. Watermust flow from the hot water faucet before turning “ON” gas to thewater heater.To fill the water heater with water:1. Close the water heater drain valve by turning the handle to the right(clockwise). The drain valve is on the lower front of the waterheater.2. Open the cold water supply valve to the water heater.NOTE: The cold water supply valve must be left open whenthe water heater is in use.3. To insure complete filling of the tank, allow air to exit by opening thenearest hot water faucet. Allow water to run until a constant flowis obtained. This will let air out of the water heater and the piping.4. Check all water piping and connections for leaks. Repair as needed.VENTINGFor proper venting in certain installations, a larger diameter vent pipemay be necessary. Consult your gas supplier to aid you in determiningthe proper venting for your water heater from the vent tables in thecurrent edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.Periodically check the venting system for signs of obstruction ordeterioration and replace if needed.The combustion and ventilation air flow must not be obstructed.The water heater with draft hood installed must be connected to achimney or listed vent pipe system, which terminates to the outdoors.Never operate the water heater unless it is vented to the outdoors andhas adequate air supply to avoid risks of improper operation, explosionor asphyxiation.• For proper draft hood attachment, the draft hood legs may be angledslightly inward.• Place the draft hood legs in the receiving holes on the top of thewater heater. The legs will snap in the holes to give a tight fit.Secure draft hood with the supplied brackets.• Place the vent pipe over the draft hood. With the vent pipe in position,drill a small hole through both the vent pipe and draft hood. Securethem together with a sheet metal screw, see Figure 11.Obstructed or deteriorated vent systems may present serious healthrisk or asphyxiation.FIGURE 11.VENT DAMPERS - Any vent damper, whether it is operated thermally orotherwise must be removed if its use inhibits proper drafting of thewater heater.The vent pipe from the water heater must be no less than the diameterof the draft hood outlet on the water heater and must slope upward atleast 1/4 inch per linear foot (21 mm per meter), see Figure 12.Thermally Operated Vent Dampers: this gas-fired water heater has athermal efficiency at or above 80% which may produce a relativelylow flue gas temperature. Such temperatures may not be high enoughto properly open thermally operated vent dampers. This would causespillage of the flue gases and may cause carbon monoxide poisoning.12All vent gases must be completely vented to the outdoors of thestructure (dwelling). Install only the draft hood provided with the newwater heater and no other draft hood.Vent pipes must be secured at each joint with sheet metal screws.
Make sure the gas supplied is the same type listed on the model ratingplate. The inlet gas pressure must not exceed 14 inch water column(2.6 kPa) for natural and propane (L.P.) gas. The minimum inlet gaspressure shown on the rating plate is that which will permit firing atrated input.FIGURE 12.There must be a minimum of 6” (153 mm) clearance between singlewall vent pipe and any combustible material. Fill and seal any clearancebetween single wall vent pipe and combustible material with mortarmix, cement, or other noncombustible substance. For other than singlewall, follow vent pipe manufacturer’s clearance specifications. Toinsure a tight fit of the vent pipe in a brick chimney, seal around the ventpipe with mortar mix cement.Failure to have required clearances between vent piping and combustiblematerial will result in a fire hazard.Be sure vent pipe is properly connected to prevent escape of dangerousflue gases which could cause deadly asphyxiation.If the gas control valve is subjected to pressures exceeding 1/2 poundper square inch (3.5 kPa), the damage to the gas control valve couldresult in a fire or explosion from leaking gas.If the main gas line shut-off serving all gas appliances is used, also turn“off” the gas at each appliance. Leave all gas appliances shut “off”until the water heater installation is complete.A gas line of sufficient size must be run to the water heater. Consultthe current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54 andyour gas supplier concerning pipe size.There must be:• A readily accessible manual shut off valve in the gas supply lineserving the water heater, and• A drip leg (sediment trap) ahead of the gas control valve to helpprevent dirt and foreign materials from entering the gas controlvalve.• A flexible gas connector or a ground joint union between the shutoff valve and control valve to permit servicing of the unit.Be sure to check all the gas piping for leaks before lighting the waterheater. Use a soapy water solution, not a match or open flame. Rinseoff soapy solution and wipe dry.The minimum inlet gas pressure shown on the rating plate is that whichwill permit firing at the rated input.Chemical vapor corrosion of the flue and vent system may occur if airfor combustion contains certain chemical vapors. Spray canpropellants, cleaning solvents, refrigerator and air conditionerrefrigerants, swimming pool chemicals, calcium and sodium chloride,waxes, bleach and process chemicals are typical compounds whichare potentially corrosive.GAS PIPINGStandard Models are for installation up to 2,000 feet (610 m) abovesea level.13High Altitude models are for installation from 2,000 feet(610 m) to 4,500 feet (1,370 m) above sea level.If a standard model is installed above 2,000 feet (610 m) or high altitudemodel is installed above 4,500 feet (1,370 m), the input rating should bereduced at the rate of 4 percent for each 1000 feet (305 m) above sealevel which requires replacement of the burner orifice in accordancewith National Fuel Gas Code ANSI Z223.1/NFPA 54 or Contact yourlocal gas supplier for further information.Failure to replace the standard orifice with a high altitude orifice wheninstalled at elevations above 2,000 feet (610 m) or above 4,500 feet(1,370 m) for high altitude model could result in improper and inefficientoperation of the appliance, producing carbon monoxide gas in excessof safe limits, which could result in serious injury or death. Contactyour local gas supplier for any specific changes which may berequired in your area.
