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 9B, 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. Open the ball valve. Refer to Sections 5 and 6 for instructions on priming the pump and starting
the burner.
