Filling The Water Heater; Gas Connections - Giant PV1 Owner's Manual

INSTALLATION INSTRUCTIONS
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 11). An indication of pressure build-up is fre-
quent 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

WARNING
NEVER operate the water heater unless it is
DANGER
completely filled with water. Failure to follow
this instruction can result in premature fail-
ure of the water heater that is not covered by
the warranty.
AVERTISSEMENT
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 all of the hot water faucets in the house
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

WARNING
DO NOT attempt to use this water heater with
DANGER
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.
AVERTISSEMENT
The gas piping must be installed as indicated in
Figure 11. For the correct size of piping for this water
heater, consult CAN/CSA B149.1, National Gas and
Propane Installation Codes (in Canada) and/or the
National Fuel Gas Code, ANSI Z223.1/NFPA 54,
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 con-
trol 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.
WARNING
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
AVERTISSEMENT
be leak tested before placing the appliance into opera-
tion. 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 1 /
2
propane gases. Pressures in excess of
can damage the gas control valve, 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
water heater and its gas supply manual shut-off
valve must be disconnected from the gas supply
piping 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
manual shut-off valve must be closed.
WARNING
U.L. and CSA recognized fuel gas and Carbon
Monoxide (Co) detectors are recommended in
all applications and should be installed using the
manufacturer's instructions and local codes, rules
or regulations.
