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.
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 pressure testing of that
system at pressures in excess of 3/8
psi (10.5” w.c.) for natural gas.
The water heater must be isolated
from the gas piping system by
closing the manual gas shut-off valve
during any pressure testing of the
gas supply piping at pressures equal
to or less than 3/8 psi (10.5” w.c.)
for natural gas.
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. The National Fuel Gas
Code (NFGC) mandates a manual
gas shut-off valve: See (NFGC) for
complete instructions.
If flexible connectors are used, the
maximum length shall not exceed
36”.
If lever type gas shut-offs are
used,they shall be T-Handle type.
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.
Where a sediment trap is not
incorporated as part of the appliance,
a sediment trap shall be installed
downstream of the equipment
shutoff valve as close to the inlet
of the appliance as practical at the
time of the appliance installation.
The sediment trap shall be either a
tee fitting with a capped nipple in
the bottom outlet or other device
recognized as an effective sediment
trap. DO NOT use excessive force
(over 31.5 ft lbs.) in tightening
the pipe joint at the gas control
(thermostat) 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 10.5” w.c. for
natural gas, or 14” w.c. for 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.
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
control (thermostat) should also be
leak tested after the water heater is
placed in operation.
WARNING: Never use
an open flame to test for
gas leaks, as property
damage, personal injury, or
death could result.
High Altitude
This water heater is certified for
installations up to 10,200 feet above
sea level.
!
WARNING: Installations above
10,200 feet are not authorized and
may result in improper and inefficient
operation of the appliance, producing
carbon monoxide gas in excess of
acceptable limits, which could result
in serious injury or death.
WARNING: Failure to
install a water heater
suitable for the altitude at
the location it is intended
to serve, can result in
improper operation of the
appliance resulting in
property damage and/or,
producing carbon
monoxide gas, which could
result in personal injury,
or death.
