GENERAL RULES: Whether you are installing a new appliance or replacing old vent material on an existing appliance, the following general gas venting rules apply. If any of these rules were not followed in your old installation, now is the time to correct the design of the vent system for maximurr safety and efficiency. 1. 1" minimum clearancef to combustible material is required throughout the installation. Clearance space must be filled with air, not insulating material. 2. Dura -Vent Type 8 Gas Vent may not be combined with any components of any other name brand or design of venting material within a single installation. 3. The diameter of the gas vent used must never be smaller than the diameter of the appliance draft hood outlet. 4. Where possible, vent straight up from the appliance draft hood outlet. If offsets or laterals are necessary, keep the degree of turn to a mini mum and the distance between the elbows as short as possible to minimize draft resistance. 5. Angled runs or laterals should be supported by a "sling" of metal strapping hung from the ceiling joists or roof rafters. 6. Most authorities recommend that "Gas vents shall extend at least 2 feet above the highest point where they pass through the roof, and at least 2 feet higher than any portion of the building within 10 feet," This recommendation should be followed unless local code requirements state otherwise. All vents extending more than 5 feet above the roof should be securely braced or guyed. 7. Where vent pipe is to pass through an occupied living space, pipe must be enclosed, maintaining 1" minimum air clearance to combustibles.

Cut and frame -in a square opening in the ceiling and /or roof large enough h t �► q P 9 9 9 9 to o ��;, ; .,_ allow the required 1" minimum clearance from the vent pipe to the wood members. NOTE: If the vent is to pass through one or more floors or ceilings before exiting the roof, a sheet metal firestop (not included in kit) must be made for each. Cut a hole, the same size as the outside diameter of the pipe, in a square of sheet metal not less than 28 gauge galvanized steel. The square should be equal to the outside dimension of the framed -in opening. This will be placed down over the vent pipe and nailed to the top of the joists and framing members. At the roof, the flashing provided will serve as a firestop. 5. At the Draft Hood Connector, begin installing pipe sections by joining the male end of one pipe to the female end of the next; twist to lock, The adjustable length (Part #4) is used last to allow adjustment to proper height. 6. Continue assembling pipe sections, placing firestops where necessary, until the vent extends through the roof a sufficient distance to conform to General Rule #6 . or local codes. 7. Place Flashing (Part #3) over vent pipe and adjust to fit tightly against roof, with the vont pipe held in position maintaining 1" minimum clearance. Place upper edge and sides of flashing under the shingles and nail to the roof. Do not nail exposed lower edge, of flashing. Seal all nail heads to prevent Leakage. Apply non- hardening mastic (not included in kit) to the top of the flashing where it meets the vent pipe; place Storm Collar (Part #2) over pipe and press into mastic. Apply more mastic around the storm collar junction with the pipe. 8. Snap -lock the Vent Top .(Part #1) to the top of the pipe. .t. 1. Position appliance according to appliat\ce, nufacturer's instructions. • 2. Place Draft Hood Connector (Part #5),w ingte•wall end down, into the appliance draft hood outlet. 3.

To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning "ON" gas to the water heater. To fill the water heater with water: 1. Close the water heater drain valve by turning the han- dle to the right (clockwise). The drain valve is on the lower front of the water heater. 2. Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open when the water heater is in use. 3. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a cbnstant flow is obtained. This will let air out of the water heater and the piping. 4. Check all new water piping for leaks. Repair as needed. Venting WARNING --- VENT DAMPERS - Any vent damper, whether it is operated thermal) or otherwise must be removed if its use inhibits proper drafting of the water heater. Thermally Operated Vent Dampers: Gas -fired water heaters having thermal efficiency in excess of 80% may produce a relatively low flue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. Thfi would cause spillage of flue gases and may cause carbon monoxide poisoning. Vent dampers must bear evidence of certification as com- plying with the latest edition of the American National Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically and mechanically ctuated vent dampers). Before installation of any vent damper, consult the local gas utility for further information. WARNING To insure proper venting of this gas -fired water heater, the correct vent pipe diameter must be utilized. Any addi- tions or deletions of other gas appliances on a common vent with this water heater may adversely affect the oper• ation of the water heater. Consult the local gas utility if any such changes are planned. for proper venting in certain installations, a larger diameter vent pipe may be necessary. Due to great variances in installations, unforeseeable by the manufacturer of the water heater, you must consult your gas company to aid you in determining the proper venting for your water heater from the vent tables in the latest edition of the National Fuel Gas Code ANSI Z223.1, also referred to as NFPA 54. 15 Check the venting system for signs of obstruction or deterio- ration and replace if needed. The combustion and ventilation air flow must not be obstructed. WARNING The water heater with draft hood installed must be connect- ed to a chimney which terminates to the outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper opera- tion, explosion or asphyxiation. WARNING - Obstructed or deteriorated vent systems may present serious health risk or asphyxiation. WARNING The vent pipe from the water heater must be no less than the diameter of the draft hood outlet on the water heater, and must slope upward to the chimney at least 1/4 inch per linear foot. All vent gases must be completely vented to the outdoors of the structure (dwelling). Install only the draft hood pro- vided with the new water heater and no other draft hood. Vent pipes must be secured at each joint with sheet metal screws. MIN. '/, INCH RISE PER LINEAR FOOT VENT PIPE INSTALLATION TO CHIMNEY There must be a minimum of 6 inch clearance between single wall vent pipe and any combustible material. Fill and seal any clearance between single wall vent pipe and combustible material with mortar mix, cement, or gther noncombustible substance. For other than single wall, fol- low vent pipe manufacturer's clearance specifications. To insure a tight fit of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement. WARNING Failure to have required clearances between vent piping and combustible material will result in a lire hazard. Installing thdlNew Water He, • •r (iionl'd) Venting (cont'd) WARNING Be sure vent pipe is properly connected to prevent escape of dangerous flue gases which could cause deadly asphyxiation, WARNING Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain chemical. vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride waxes, bleach and process chemicals are typical compounds which are potentially corrosive. Gas Piping WARNING Make sure the gas supplied is the same type listed on the model rating plate. The Inlet gas pressure must not exceed 14 inches water column ('h pound per square inch (3.SkPa)1. WARNING If the gas control valve is subjected to pressures exceeding 'h pound-per square inch (3.5kPa), the damage to the gas con- trol valve could result in a fire or explosion from leaking gas. WARNING If the main gas line shutoff serving all gas appliances is used, also tum "OFF' the gas at each appliance. leave all gas appli- ances shut off until the water heater installation is complete. A gas line of sufficient size must be run to the water heater. Consult the latest edition of National Fuel Gas Code ANSI Z223.1, also referred to as NFPA54 and the gas company concerning pipe size. There must be: -A readily Accessible manual shut off valve in the gas sup- ply line serving the water heater, and -A drip leg (sediment trap) ahead of the gas control valve to help prevent dirt and foreign materials from entering the gas control valve. -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 Teaks before lighting the water heater. Use a soapy water solution, not a match or open flame. Rinse off soapy solution and wipe dry. When installed at elevations above 2,000 feet, input rat- ings should be reduced at the rate of 4 percent for each 1.000 feet above sea level. WARNING The appliance and its gas connedion must be leak test- ed before placing the appliance in operation. 16 WARNING The appliance and its individual shutoff valve must be discon- nected from the gas supply piping system during any testing of that system at test pressures in excess f'b pot per square inch (3SkPs). The appliance must be isolated from the ga supply piping sys- tem by dosing its individual manual shu off valve airing any pressure testing of the gas supply piping system at test prey sures equal to or less than 'h pound per square inch (3.5kPa). WARNING Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum LPropane (L.P.)) gases. Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown.
