Cleaning Suction Line Strainer

The suction line strainer should be cleaned every 30
days of operation. The element is a washable metal
element. If your waste oil is extremely dirty, this strainer
may need to be cleaned more frequently. Your vacuum
gauge will help you determine when the filter needs
cleaning. The vacuum gauge reading should not exceed
5" HG of vacuum. If it does, the strainer needs cleaning.

1.

Disconnect power to the boiler.

2

.

While holding the lower housing, unscrew the cen-
ter bolt on the top of the suction line strainer.

3.

Rinse the filter and lower housing in solvent.

4.

Air dry the strainer and lower housing.

5

.

Re-assemble the strainer, ensuring the rubber gas-
kets, spring and o-rings are in place.

6.

Fill the lower housing with waste oil or fuel oil.

7

.

Position the lower housing to the top making sure
the o-ring is properly seated. Secure the top and
bottom together using the bolt, washer and gas-
ket removed earlier.

8

.

Prime the fuel pump (see page 28).
