External Inspection & Cleaning of the
Base-Ring Filter
1,
At least annually, check the base-ring filter (Figure 34) 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.
