Gas Supply; High Altitude - Rheem GG50T06PVT Use And 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.
WARNING: Never use
an open flame to test for
gas leaks, as property
damage, personal injury,
or death could result.
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.

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
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
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, or 1/2 psi (14"
w.c.) for LP gas.

High Altitude

Input rating of this water heater is
based on sea level operation. At higher
elevations the actual input rate may be
lower than the value listed on the rating
label. This water heater can be installed
at elevation up to 7,700 feet without any
change or modification.
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.) 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.
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.
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, or
1/2 psi (14" w.c.) for LP gas.
For installation between 2,000 feet
(609 m) and 7,700 feet (2347 m), refer
to the Venting Information tables on page
13 and 14 for maximum vent length.
Contact the local gas supplier for more
information.
