Burner Ignitor Assembly; Water Heater Tank; Temperature And Pressure-Relief Valve; Venting System Inspection - Giant PV1 Owner's Manual

GENERAL MAINTENANCE
Because of the large amounts of water that can
condense, it is very important that a drain pan be
installed under the water heater (refer to Figure
11). Under no circumstances is the manufac-
turer to be held liable for any water damage, in
connection with this water heater. If the problem
does not go away and water continues to drip after the
water heater has heated up, check all of the plumbing
connections to make sure they are not leaking.

Burner Ignitor Assembly

Every three (3) months, check the burner and ignitor
assembly. Remove the outer access door and look
through the sight glass to examine the flames. A soft
blue flame indicates proper gas combustion. A yellow
tipped flame indicates poor combustion. With a vacuum
cleaner, remove any dust, lint and dirt accumulation
on or around the combustion chamber and in the
combustion air intake holes.

Water Heater Tank

Drain a pail of water through the drain valve at least
once a year. This will remove excess sediment
from the bottom of the tank. This sediment, if allowed
to accumulate, will reduce the efficiency and the life of
the tank.

Temperature and Pressure-Relief Valve

Manually operate the temperature and pressure-relief
valve at least once a year, standing clear of the outlet
to avoid being burned. Lift and release the operating
lever on the valve to make it operate freely. If, after
manually operating the valve, it fails to completely
reset itself and continues to discharge water, replace
it with a new one.

Venting System Inspection

The venting system must be thoroughly inspected
once a year. Check the area where the water heater
is located to make sure that there is enough clean
combustion and ventilation air. Remove any possible
obstructions that would prevent proper air circulation
and venting. Check the venting system to make sure
that all of the connections are securely fastened and
that all of the joints are properly sealed. If any part of
the venting system is damaged, it must be replaced
by a qualified service technician.

Anode

This water heater is equipped with an anode that
is designed to prolong the life of the glass-lined
tank. The anode is slowly consumed, protecting the
glass-lined tank from corrosion. The anode should
be checked every two (2) years. If more than half
of the anode has been consumed, it should be
replaced. Instructions on how to change the anode
can be obtained from the manufacturer.
The life expectancy of the water heater is reduced
where a water softener is introduced to fight hard
water, because the sodium salts added by a soft-
ener make this water extremely conductive. In these
conditions, the anode is consumed more rapidly and
should be verified every year.
In certain water conditions, the anode will react with
the water, producing discoloured or smelly water.
The most common complaint is hot water that smells
like rotten eggs. This phenomenon is the result of the
reaction between the anode and hydrogen sulfide
gas dissolved in the water, which occurs frequently in
well systems. This problem can usually be eliminated
or reduced by changing the anode to a type more
suitable for these conditions (aluminum anode) and
by chlorinating the water heater and plumbing sys-
tem. If the problem persists, special filtration equip-
ment may be required. Under no circumstances is
the anode to be removed from the water heater on a
permanent basis. Removal of the anode will lead
to premature failure of the water heater and
void the warranty.
Hydrogen gas can be produced in a hot water sys-
tem that has not been used for a long period of time
(generally two [2] weeks or more). HYDROGEN
GAS IS EXTREMELY FLAMMABLE. It is highly
recommended to open the hot water faucet in the
kitchen for several minutes before you use any
electrical appliances connected to the hot water
system, such as a dishwasher or washing machine.
If hydrogen gas is present, there will be an unusual
sound, such as air escaping through the pipe, as
the hot water faucet is opened. DO NOT smoke
or introduce an open flame near the faucet when it
is opened.

Draining the Water Heater

To completely drain the water heater:
1) Unplug the power cord from the wall socket.
2) Close the gas supply manual shut-off valve.
3) Close the cold water supply manual shut-off valve.
4) Connect one end of a garden hose to the water
heater drain valve and put the other next to a free-
flowing drain.
5) Open the drain valve by inserting a flat head
screwdriver into the slot on the head of the drain valve
and turning the knob counterclockwise
6) Open a hot water faucet to allow air into the system.
