INSTALLATION INSTRUCTIONS
A discharge line must be installed into the relief
valve. The discharge line:
• Must not be smaller than the outlet pipe size of the
relief valve.
• Must not terminate less than six (6) inches
(15.2 cm) and not more than twelve (12) inches
(30.5 cm) above a floor drain.
• Must not be restricted in any way. Do not thread,
cap, or in any way restrict the end of this outlet.
• Must be of a material capable of withstanding
210°F (99°C) without distortion.
• Must be installed to allow complete drainage of the
relief valve and discharge line.
• Must terminate at an adequate free-flowing drain.
Pressure Build-up in a Water System
When the water heater operates, the heated water
expands creating a pressure build-up. This is a natural
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 expansion 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 faucets
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,
personal 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 CSA B149.1 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
supply 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 to prevent dirt
from entering it. A union must be installed between the
gas control 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 property
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, resulting in
a fire or explosion from leaking gas. For purposes of
adjustment, 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 piping system,
