All boilers equipped with burner swing door have a potential hazard w hich can cause severe

A.
ALWAYS INSPECT INSTALLATION BEFORE
STARTING BURNER.
B
. FILL HEATING SYSTEM WITH WATER. Refer to
Section III, G.
C.
CHECK CONTROLS, WIRING AND BURNER to be
sure that all connections are tight and burner is rigid,
that all electrical connections have been completed and
fuses installed, and that oil tank is filled and oil lines
have been tested.
D
. LUBRICATION — Follow instruction on burner and
circulator label to lubricate, if oil lubricated. Most
motors currently used on residential type burners
employ permanently lubricated bearings and thus do
not require any field lubrication. Water lubricated
circulators do not need field lubrication.
Do not over-lubricate. This can cause as much trouble
as no lubrication at all.
E
. SET CONTROLS with burner service switch turned
"OFF".
1. SET ROOM THERMOSTAT about 10° above
room temperature.
2. PRESS RED RESET BUTTON on R8184P Oil
Primary Control and release.
3. Set high limit dial on L8148 at temperature to suit
requirements of installation.
