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).
EL22-I
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 certied 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 dierent 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 unit 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.
