Gas Supply
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.
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.
The branch gas supply line to the water
heater should be clean, properly sized,
steel pipe or other approved gas piping
material.
A 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"
(91.4 cm) and must meet the requirements
in ANSI Z21.24/CSA 6.10- Connectors for
Gas Appliances.
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. (42.7 Nm)] in tightening the pipe
joint at the gas control 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 14.0 in. w.c. (3.5 kPa)
w.c. for natural 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.
Pressure Testing the Gas Supply System
The water heater and its individual shut
off valve must be disconnected from the
gas supply piping system during any
pressure testing of that system at test
pressures in excess of 1/2 psi (3.5 kPa).
The water heater must be isolated from
the gas supply piping system by closing
it's individual manual shut off valve
during any pressure testing of the gas
supply piping system at test pressures
equal to or less than 1/2 psi (3.5 kPa)
High Altitude
This water heater is suitable and certified
for use at high altitude. Refer to the
altitude label on the water heater for
maximum allowable installation altitude.
!
WARNING: Installations above the
rated altitude as specified on the
altitude label 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.
