Suction Line
: Field provides piping from Check Valve to Filter. Note Check Valve has flow
direction arrow. Secure piping to keep the Strainer 6”+ off the bottom of the tank. Plan ahead
for routine service of components. Use minimal number of fitting to reduce chances of suction
leaks. Consult your dealer’s experience for methods that work in your application. TIP: It is
wise to fill the filters/plumbing on the suction side of the pump with clean oil prior to priming the
system. This will minimize priming time and save wear on pump seals.
Pressure Line
(Oil Pump Outlet): After the provided Nipple/Tee/Gauge the 1/4” Check Valve
may be installed to help keep oil pressure for the burner. The field provides tubing or piping to
reach from here to the 1/2" Valve near the Burner. A 3/8 inch or 1/2 inch FLARED (never use
compression) soft copper tubing is commonly used. Hard metal tubing or metal pipe is acceptable
but may incur more cost, has more potential for leaks, and is not flexible to swing the burner open
for routine cleaning. Consult your dealer on sizing for your application.
Try to run the oil piping uphill from the pump to the burner to allow entrapped air to escape at the
burner. Avoid high spots in the oil piping or looping the line above the burner as this creates a
trap and collects air. Collected air will delay the oil getting to the nozzle, causing a weak flame,
slow or failed ignition, or pressure gauge and flame pulsation.
[ TIP: spiral or loop some excess tubing at the burner to allow the burner door to swing open w/o
having to disconnect the oil line tubing.
Do not connect oil line to Valve at the Burner until after the oil line is purged of dirt and air.
[Suggestion: to ease future oil line purges, adding a tee and drain cock near the burner allows dirt
and air to be purged without disconnecting the line from the burner.]
