External
Inspection
& Cleaning
of the
Base-Ring
Filter
1.
At least annually, check the base-ring filter (Figure 38) for
any dust or debris that may have accumulated
on the filter
screen. NOTE: If the water heater is located in an area that
is subjected to tint and dirt, it may be necessary
to check
the base-ring filter more frequently.
2.
Follow the Lighting Instructions to turn off the water heater
and allow it to coot for 10 minutes before attempting to clean
the base-ring filter.
3.
Use a vacuum cleaner with a hose attachment
to remove
any dust or debris that may have accumulated
on the filter.
NOTE: If unable to inspect or clean the base-ring filter, follow
the "Cleaning the Combustion Chamber and Flame-arrestor"
instructions.
4,
After the base-ring
filter has been cleaned,
follow the
Lighting Instructions to return the water heater to service.
Removing
the Manifold/Burner
Assembly
1.
Turn off the gas supply to the water heater at the manual
gas shut-off valve. This valve is typically located beside the
water heater (Figure 11). Note the position of the shut-off
valve in the open/on position then proceed to turn it off.
2.
On the lower front of the water heater, locate the gas control
valve/thermostat
(see Figure 32). Before performing
any
maintenance,
it is important to turn the temperature dial on
the gas control valve/thermostat
to its lowest setting.
3.
On top of the gas control valve/thermostat,
turn the gas
control knob to the "OFF" position.
