There must be a minimfim of 6" clearance between single wall vent pipe and any combustible material. Fill and seal any clear- ance between single wall vent pipe and combustible material with mortar mix, cement, or other noncombustible substance. For other than single wall, follow vent pipe manufacturer's dear- ance specifications. To insure a tight fit of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix
cement.

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 gascompany concern- ing pipe size.
There must be:
•A readily accessible manual shut offvalve in the gas supply 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 shutoffvalve 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 offsoapy solution and wipe dry.

High Altitude Models are for installation from 3,300 to 5,500 feet above sea level.
Ifa standard model is installed above 3,300 feet or a high altitude
model is installed above 5,500 feet, the input rating must be reduced at the rate of 4 percent for each 1,000 feet above sea level.
