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 pressure 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 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.
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“ 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
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).
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. 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.
