model rating plate. The inlet gaspressuremust not exceed
10.5in. water column (2.6kPa)for natural gasor 13 in. water
column (3.2kPa) for propane(LR) gas.The minimum inlet
gaspressurelistedon the model rating plate is for the pur-
poseof inputadjustment.
_,WARNING
If the gascontrol valveissubected to pressures exceeding½
poundper squareinch(3.5kPa), the damageto the gascon-
tro valvecouldresult in a fire or explosion from lealdnggas.
There must be a minimum of 6" clearance between single wail
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.

cerning pipe size.
There must be:
• A readily accessible manual shut offvalve in the gas supply line
serving the water heater, and
• A drip let (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 li8hting the
water heater. Use a soapy water solution, not a match or open
flame. Rinse offsoapy solution and wipe dry.
