Air Filter Cleaning & Replacement Procedures
1. Set the ON/OFF switch on the control panel, to the OFF position. Disconnect AC power
from the unit.
2. Remove the front panel from the unit by grasping the handles and pulling outward.
3. Refer to Figure 7-11 and locate the air filters attached to the “Y” shaped duct connected to
the air/fuel valve inlet.
4. Using a flat-tip screwdriver or 5/16” nut driver, loosen the clamp securing the filter to the
“Y” duct at the air/fuel valve inlet. Remove the filter and clamp.
5. The filters may be cleaned in hot soapy water to remove oil and dirt. The filter should be
thoroughly dried and then sprayed with a light coating of oil, (NOT WD-40), prior to
reinstallation.
6. Each replacement air filter is equipped with its own clamp. Therefore, simply install the
replacement air filter on “Y” duct and tighten the clamp with a flat-tip screwdriver or 5/16”
nut driver.
7. Replace the front panel on the unit and return boiler to service use.
