Water Supply Connections Continued....
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.
• DO NOT use lead or non-approved plastic pipe.
• To conserve energy and minimize heat loss, insulation of hot
water piping is recommended.
NOTICE: The ow rate of hot water may vary when more than two
faucets (appliances, xtures, 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 Shuto 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.
A ground joint union or ANSI
design certied semi-rigid
or exible 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-o 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“ w.c.
for natural 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
The water heater and its indivdual
shuto 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
shuto valve during any pressure
testing of the gas supply piping system
at test pressures equal to or less than ½
psi (3.5 kPa).
Gas Supply
WARNING: Do not attempt to convert this water heater for use with a dierent type of gas other
than the type shown on the rating plate. Such conversion could result in hazardous operating
conditions. Please have a professional connect the gas pipe.
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
LP gas. Use compound sparingly and use on male threads only.
