Cleaning the Canister Filter
ATTENTION: Never operate the oil pump with more than 10" HG of vacuum on the vacuum gauge.
High vacuum on the suction side of the pump separates air from the oil (cavitation) and will cause the
burner to shut down.
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, remove the canister bowl, and filter element. Now pour the oil into the
container.
4. Clean the filter element and the bowl in a parts washer.
5. Referring to Figure 9A, check the condition of the O-rings. Replace any that are cracked or
worn.
6. Ensure that the canister filter is 100% airtight by firmly tightening the four bolts.
7. Open the ball valve. Refer to Sections 5 and 6 for instructions on priming the pump and starting
the burner.
