Use & Care Manual

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.
Gas Supply
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 shutoff valve: See (NFGC) for
complete instructions.
If flexible connectors are used, the maximum
length shall not exceed 36 in. (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 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 N
●m) in tightening the pipe joint at the
combination 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 natu-
ral gas, or 14.0 in. w.c. (3.5 kPa) w.c. for LP
gas. For purposes of input adjustment, the mini-
mum 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.

To Fill the Water Heater
Make certain that the drain valve is closed, then
open the shut-off valve in the cold water supply
line.
Open each hot water faucet slowly to allow the
air to vent from the water
heater and piping.
A steady flow of water from all hot water
faucet(s) indicates a full water heater.
Do not allow the flammable vapor sensor to
become submerged in water.
WARNING: The tank
must be full of water
before the water heater is
turned on. The water
heater warranty does not
cover damage or failure
resulting from operation
with an empty or partially
empty tank.
Condensation
Condensation can also form on the tank when
it is first filled with water. Condensation
might also occur with a heavy water draw and
very cold inlet water temperatures. Drops of
water falling on the burner can produce a siz-
zling or pinging sound. This condition is not
unusual, and will disappear after the water
becomes heated. However, if condensation
continues, examine the piping and fittings for
possible leaks.
Installing the Water Heater
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 combination gas
control 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.
