DO NOT use excessive force (over 31.5 ft lbs.) in tightening the pipe, particularly if pipe compound is used,
as the water heater may be damaged. Compound used on the threaded joints of the gas piping must be of
the type resistant to the action of LPG. Use compound sparingly and use on male threads only.

In regards to the HOT WATER OUTLET:
• Connections between the water heater and point(s) of use
should be as short and direct as possible.
Hot
Water
• DO NOT use lead or non-approved plastic pipe.
Tap
• To conserve energy and minimize heat loss, insulation of hot
water piping is recommended.
NOTICE: The flow rate of hot water may vary when more
than two faucets (appliances, fixtures, etc.) are being used
simultaneously.
NOTICE: The pipes MUST be completely drainable. If the
hot water faucets are located at a point higher than the water
heater, place a drain valve at the lowest point (see diagram to
the left).
The supplied Manual Gas
Appliance Shutoff Valve
must be installed at the gas
connection of the water heater
at the time of installation (see
diagram to
the left).
The branch gas supply line to
the water heater should be
clean black steel pipe or other
approved gas piping material.
The minimum BTU requirement
for flex and/or gas lines is 1" of
black steel, flex rated at 150K
BTU.
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.

A sediment trap should be
installed at the bottom of the gas
line.
The inlet gas pressure to the water
heater must not exceed 10.5 in.
w.c. for natural or 13.5 in. w.c.
for LPG. 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 water heater and its
indivdual shutoff valve must
be disconnected from the gas
supply piping system during any
pressure testing of that system
at test pressures in excess of ½
psi (3.5 kPa). The water heater
must be isolated from the gas
supply piping system by closing
its individual manual shutoff valve
during any pressure testing of the
gas supply piping system at test
pressures equal to or less than ½
psi (3.5 kPa).
