Safety Instructions Installation Instructions Operating Instructions Care and Cleaning Troubleshooting Tips Customer Service
WARNING: Do not attempt to convert this water heater for use with a different type of gas other than the type
shown on the rating plate. Such conversion could result in hazardous operating conditions.
Leak Testing
The water heater and its gas
connections must be leak tested at
normal operating pressures before
it is placed in operation.
Turn on the manual gas shut-off
valve near the water heater.
Use a soapy water solution to test
for leaks at all connections and
fittings. Bubbles indicate a gas leak
that must be corrected.
The factory connections to the gas valve
and fittings should also be leak tested
after the water heater is placed in
operation.
High Altitude…
Installations above 5000 feet require
replacement of the burner orifice in
accordance with the National Fuel Gas
Code (ANSI Z223.1/NFPA 54). Failure to
replace the orifice will result in improper
and inefficient operation of the
appliance, producing carbon monoxide
gas in excess of safe limits, which could
result in serious personal injury or
death.
Pressure Testing the Gas Supply System
The water heater and its manual gas
shut-off valve must be disconnected
from the gas supply piping system
during any high pressure testing of
that system at pressures in excess
of 1/2 PSIG (14″ W.C.).
The water heater must be isolated from
the gas piping system by closing the
manual gas shut-off valve. The valve only
needs to be closed during testing at
pressures equal to or less than 1/2 PSIG
(14″ W.C.).
Gas Supply
The branch gas supply line to the water
heater should be clean 1/2″ black steel
pipe or other approved gas piping
material.
A ground joint union or ANSI design
certified semi-rigid or flexible gas
appliance connector should be installed in
the gas line close to the water heater,
and a manual gas shut-off valve should
be installed in the gas line prior to the
union. A manual gas shut-off valve should
be at least 5 ft. above the floor and
readily accessible, for turning on or off.
Compound used on the threaded joints
of the gas piping must be of the type
resistant to the action of LP gas.
Use compound sparingly on male
threads only.
A sediment trap should be installed at
the bottom of the gas line.
Do not use excessive force (over 31.5 ft lbs.)
in tightening the pipe joint at the gas valve
inlet, particularly if Teflon pipe compound is
used, as the valve body may be damaged.
The inlet gas pressure to the water
heater must not exceed 14″ W.C. for
Natural or LP gas. For purposes of input
adjustment, the minimum inlet gas
pressure (with main burner on) is shown
on the water heater rating plate. If high
or low gas pressures are present,
contact your gas supplier for correction.
WARNING: Never use an
open flame to test for gas
leaks, as bodily injury,
property damage or death
could result.
