VENTING THROUGH A ROOF (CONT’D)

2.Only 3″ ABS Schedule 40 piping and fittings are acceptable materials on the first five feet of the outlet vent system of 75 Gal. Models and 50 Gal. 65,000 Btu/Hr Models only.

3.3″ PVC, ABS, or CPVC Schedule 40 piping and fittings are acceptable materials for the inlet vent system and for the out- let vent system (after the first five feet for 75 Gal. Models and 50 Gal. 65,000 Btu/Hr Models only).

4.It cannot be connected to existing vent piping or chimney.

5.It must terminate vertically to the outdoors.

6.The total vertical and horizontal vent runs cannot exceed the maximum length with a maximum number of 90˚ elbows as specified in the table below. If more elbows are required, the venting distance must be reduced 5 feet for every 90° elbow.

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 10.5 in. water column (2.6kPa)for natural gas or 13 in. water column (3.2 kPa) for propane (L.P.) gas. The minimum inlet gas pressure listed on the rating plate is for the purpose of input adjustment.

WARNING

If the gas control valve is subjected to pressure exceed- ing 1/2 pound per square inch (3.5kPa), the damage to the gas control 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 turn “OFF” the gas at each appliance. Leave all gas appliances turned “OFF” until the water heater installation is complete.

A gas line of sufficient size must be run to the water heater. Consult the current edition of National Fuel Gas Code ANSI Z223.1, also referred to as NFPA 54 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 leaks 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 which requires replacement of the burner orifice in accordance with the National Fuel Gas Code ANSI Z223.1 / NFPA 54. Contact your local gas util- ity for further information.

WARNING

Failure to replace the orifice could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of safe limits, which could result in serious injury or death. Contact your gas supplier for any specific changes which may be required in your area.
