Cleaning The Canister Filter - Saturn 125 Operator's Manual

Periodic Burner Inspection (continued)
• Check the air pressure by observing the air gauge; proper air pressure settings are provided in
Section 6. DO NOT over fire the burner; doing so on a continual basis will damage the furnace.
• Check the combustion air band setting for the proper opening and clean away any dust/debris as
necessary. Note that the air band should NEVER be set fully open or closed.
• Check the draft over fire reading as specified in Section 8.

Cleaning the Canister Filter

ATTENTION: Never operate your furnace with more than 10" HG of vacuum on the suction side of
the pump. High vacuum separates air from the oil and results in erratic burner operation.
The following protective gear should be worn when cleaning the filter:
• Rubber gloves
• Safety goggles
1. Close the ball valve adjacent to the filter.
2. Position a container under the filter.
3. Unscrew the four bolts to drain the oil from the canister.
4. Remove the canister bowl.
5. Clean the screen and the bowl in a parts washer.
6. Referring to Figure 9A, examine the filter components as you reassemble them.
7. Check the condition of the O-rings. Replace any that are cracked or worn.
8. Ensure that the canister filter is 100% airtight by firmly tightening the four bolts.
9. After the pump head screen is serviced as well (page 9-4) open the ball valve and refer to Sections
5 and 6 for instructions on priming the pump and starting the burner.
