VENT PIPE INSTALLATION
There must be a minimum 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 clear- ance specifications. To insure a tight fit of the vent pipe in a
brick chimney, seal around the vent pipe with mortar mix cement.

Gas Piping
&WARNING
Make sure the gas suppliedis the same type listed on the modal rating plate. The inlet gaspressuremust not exceed 14 incheswater column ½ poundper squareinch (3.SkPa). The minimum inlet gas pressurelistedon the model rating plate isfor the purposeof inputadjustment.

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 concern- ing pipe size.
There must be:
•A readily accessiblemanual 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 shuroffvalve 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.
