Installation & Service Manual
NOTICE CHECK TEST PROCEDURE. A very
good test for isolating fuel side problems is

gallon pail of clean, fresh, warm #2 oil from
another source. If the burner runs successfully
when drawing out of the auxiliary pail then
the problem is isolated to the fuel or fuel lines
being used on the jobsite.
