Gas Supply; High Altitude - GE GG75T06ASK 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 bodily injury,
property damage or death
could result.

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. A
manual gas shut-off valve should be at
least 5 ft. above the floor and readily
accessible.
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.
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.
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.).

High Altitude...

Ratings of gas appliances are based
on sea level operation and need not be
changed for installations at elevations up
to 2,000 feet.
For installations above 2,000 feet, the
input must be reduced per the National
Fuel Gas Code for each 1,000 feet above
sea level. Contact the local gas supplier
for more information.
A sediment trap should be installed at
the bottom of the gas line.
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 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.
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.
The 60 Gallon unit included in this manual
is rated for up to 5,000 feet.
For installations above 5,000 feet, the
input must be reduced per the National
Fuel Gas Code for each 1,000 feet above
sea level. Contact the local gas supplier
for more information.
