WARNING: Never
use an open flame to
test for gas leaks, as
bodily injury, property
damage or death could
result.
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 thermostat
should also be leak tested after the water
heater is placed in operation.
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 psi (14″ w.c.).
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 1/2 psi (14″ w.c.).
Gas Supply
Check the markings on the water heater’s
rating plate to be certain the type of gas
being furnished corresponds to that for
which the water heater is built. The water
heater can be converted from natural gas
to LP or vice versa. See the Conversion
Instructions section of this manual.
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 HUD code should be followed for
installation and location of a manual
shutoff valve.
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
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 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.
This water heater has been rated for installations
based on sea level operations and need not
be changed for installations at elevations
up to 5,999 feet (1,828 m). For Installation
above 5,999 feet, the input must be reduced
per the National Fuel Gas Code, ANSI Z22.1.
Contact your installer, local gas supplier, place
of purchase or the Customer Service phone
number as listed in this Use and Care Manual
for more information.
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.
