C. Main Burner and Pilot
the manufacturer 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.
Every 3 months, slide out the burner rack to inspect the burner
ports, pilot, and burner orifices. See Figure 19 for burner
assembly. Use a wire brush and vacuum cleaner to remove any
dirt or debris present. In order for the water heater to operate
properly after cleaning, make sure the burner rack is returned to
its original position.
D. Cleaning Out the Water Heater
Lime, scale, or sediment may accumulate at the bottom of
this water heater. The amount deposited will depend on the
hardness of the water supply where this water heater is installed.
The harder the water, the more sediment will accumulate. If this
sediment is left unchecked, it will reduce the efficiency and life
of the water heater.
To Control Sediment Build-Up:
1. Drain a pail of water through the drain valve once a
month.
2. Every 3 months, use the following procedure to clean
out the bottom of the water heater through the cleanout
hole opening:
• Drain out the water. (Refer to Draining the Water
Heater ).
• Remove the cleanout door on the lower right side of the
water heater jacket.
• Undo the 6 hex head bolts securing the cleanout cover
and remove the cover.
• Remove any excess sediment accumulation from the
bottom of the water heater, taking care not to damage
the water heater’s glass lining.
• Inspect the cleanout cover’s gasket for wear and replace
it if necessary.
• Replace the cleanout cover and cleanout cover door.
• Refill the water heater (refer to
Filling the Water Heater )
and turn on the gas (refer to Lighting Instructions ).
E. Temperature and Pressure Relief Valve
Manually operate the temperature and pressure relief valve
at least once a year. Stand 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 and continues to discharge water, replace it
with a new valve (refer to
Draining the Water Heater ).
F. 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. Make sure
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.
Test the ventilation system to make sure that it is venting
properly (refer to
Drafthood Operation ).
G. Anode
This water heater is equipped with multiple anode rods that
are designed to prolong the life of the glass-lined tank. By
the electrolytic action, these anodes are slowly consumed,
protecting the glass-lined tank from corrosion. Each anode
should be checked every 2 years. If more than half of an anode
has been consumed, it should be replaced. Instructions on how
to change an 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. The
sodium salts added by a softener make this water extremely
conductive. In these conditions, the anodes are consumed
more rapidly and should be inspected every year.
In certain water conditions, the anodes will react with the
water, producing discolored 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
anodes 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 anodes
to a type more suitable for these conditions (aluminum
anodes) and by chlorinating the water heater and plumbing
system. If the problem persists, special filtration equipment
may be required. Under no circumstances are the anodes to
be removed from the water heater on a permanent basis.
Removal of the anodes will lead to premature failure of the
water heater and void the warranty.
Hydrogen gas can be produced in a hot water system that has
not been used for a long period of time (generally 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.
H. Draining the Water Heater
To completely drain the water heater:
1. Turn off gas to the appliance (refer to Turn Off Gas to
Appliance ).
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 turning the knob
counterclockwise.
6. Open a hot water faucet to allow air into the system.
I. Vacation
If you are planning a vacation or other prolonged absence, it
is highly recommended to shut off the gas supply and the cold
water supply to the water heater. This will save energy, protect
against property damage in the event the water heater leaks,
and prevent the build-up of hydrogen gas. The water heater and
piping should be drained if exposed to freezing temperatures.
Remember to check the water heater thoroughly after it has
