Start the Burner
Step 1: To bleed the fuel pump, attach a clear
plastic hose over the vent fi tting. Loosen the fi t-
ting and catch the oil in an empty container. Tight-
en the fi tting when all the air has been purged
from the oil supply system.
Step 2: If the burner locks-out on safety during
bleeding, reset the safety switch and complete
the bleeding procedure. Note — For R7184 pri-
mary controls, see Technician’s Quick Reference
Guide, part number 61351 or 61465, for special
pump priming sequence.
Step 3: If the burner stops after a fl ame is estab-
lished, additional bleeding is probably required.
Repeat the bleeding procedure until the pump is
primed and a fl ame is established when the vent
fi tting is closed.
Prepare for combustion tests by drilling a
1/4
”
sampling hole in the fl ue pipe between the appli-
ance and the barometric draft regulator. Seal this
hole when testing is complete. (See appliance
manufacturer for location.)
Loosen the splined nut approximately one turn.
(DO NOT loosen the upper acorn nut. This is
used only for setting the zero adjustment.) (See
Figure 5.)
A 5/16” nut driver or fl at blade screwdriver can
be used to turn the adjustment screw for head/air
setting.
