INSTALLATION INSTRUCTIONS
Pressure Build-up in a Water System
When the water heater operates, the heated water
expands creating a pressure build-up. This is a natu-
ral function and is one of the reasons for installing a
temperature and pressure-relief valve. If the cold
water supply line has a built-in water meter, check
valve, or pressure-reducing valve, a suitable expan-
sion tank must be installed to prevent pressure build-
up or water hammer effect, otherwise the warranty is
void (see Figure 8). An indication of pressure build-up
is frequent discharges of water from the relief valve.
If the relief valve discharges water on a continuous
basis, it may indicate a malfunction of the relief valve,
and a qualified service technician must be called to
have the system checked, and the problem corrected.
Filling the Water Heater
NEVER
operate the water heater unless it is
completely filled with water. Failure to follow this
instruction can result in premature failure of the
water heater that is not covered by the warranty.
Check that all of the water piping connections have
been made. To fill the water heater:
1) Make sure that the water heater drain valve is
closed by inserting a flat head screwdriver into the
slot on the head of the drain valve and turning the
knob clockwise
.
2) Open the cold water supply manual shut-off valve.
This valve must remain open as long as the water
heater is in use. Never operate the water heater with
the cold water supply manual shut-off valve closed.
3) To make sure the water heater is completely full of
water, open hot water faucets to let the air out of the
water heater and plumbing system. Leave the fau-
cets open until a constant flow of water is obtained.
4) Check all of the plumbing connections to make
sure there are no leaks.
Gas Connections
DO NOT
attempt to use this water heater with
any gas other than the type of gas shown on the
water heater rating plate. Failure to follow this
instruction can result in property damage, per-
sonal injury, or death.
The gas piping must be installed as indicated in
Figure 8.
For the correct size of piping for this water
heater, consult CAN/CGA B149 in Canada and/or the
National Fuel Gas Code, ANSI Z223.1 in the United
States. Only new piping with cleanly cut threads may
be used, together with a suitable sealing compound
that is approved for natural and propane gases. It is
mandatory that a readily accessible manual shut-off
valve be installed in the gas supply line. The gas sup-
ply manual shut-off valve must be close to the water
heater. A drip leg (sediment trap) must be installed in
the gas line ahead of the gas control valve to prevent
dirt from entering it. A union must be installed between
the gas control valve and the gas supply manual shut-
off valve for easy maintenance of the water heater.
NEVER
use an open flame to test for gas leaks.
A fire or explosion could occur resulting in prop-
erty damage, personal injury, or death.
The water heater and its gas connection must be leak
tested before placing the appliance into operation. To
leak test the system:
1) Turn on the manual gas shut-off valve near the
water heater.
2) Use a soapy water solution to test all connections
and fittings for leaks. Bubbles indicate a gas leak.
3) Correct all leaks.
Make sure that the inlet pressure to the water heater
does not exceed fourteen (14) inches in W.C. (water
column) for both natural and propane gases. Pressures
in excess of 1/2 pound per square inch (3.5 kPa) can
damage the gas control valve, resulting in a fire or
explosion from leaking gas. For purposes of adjust-
ment, the minimum inlet pressure is indicated on the
water heater rating plate.
If any pressure testing of the gas line is undertaken
at test pressures in excess of 1/2 psig (3.5 kPa),
the water heater and its gas supply manual shut-off
valve must be disconnected from the gas supply pip-
ing system, and the end of the pipe sealed with a
female cap. If the testing is to be undertaken at a test
pressure less than 1/2 psig (3.5 kPa), the gas supply
manual shut-off valve must be closed. For purposes
of adjustement, the minimum inlet pressure should be
one (1) inch water column above the operating manifold
pressure. If manifold pressure is tested at the outlet pres-
sure tap of the gas control, results should show 4” w.c.
-+
0,3” w.c..
A high altitude orifice
MUST BE
installed for
water heaters operating above 2,000 feet. Failure
to follow this instruction can result in property
damage, personal injury, or death.
