Installation & Service Manual
A. ALWAYS INSPECT INSTALLATION BEFORE
STARTING BURNER.
1. Verify that the venting, water piping, oil piping,
and electrical system are installed properly.
Refer to Installation Instructions contained in
this manual.
2. Confirm all electrical, water and oil supplies
are turned off at the source and that the vent is
clear from obstructions.
WARNING
Completely read, understand and follow all
instructions in this manual before attempting
start up.
B. FILL HEATING SYSTEM WITH WATER.
CLEAN HEATING SYSTEM if boiler water is dirty.
Refer to Maintenance and Service Instructions
Section of this manual for proper cleaning
instructions for water boilers.
1. Fill entire heating system with water and vent
air from system. Use the following procedure
on a series loop or multi-zoned system
installed as per Figures 3-3, and 3-4, to remove
air from system when filling:
a. Close full port ball valve in boiler system
piping.
b. Isolate all zones by closing zone valves or
shut-off valves in supply and return of each
zone(s).
c. Attach a hose to vertical purge valve in
boiler system piping.
(Note - Terminate hose in five gallon bucket at
a suitable floor drain or outdoor area).
d. Starting with one zone at a time, open zone
valve or shut-off valve in boiler supply and
return piping.
e. Open purge valve.
f. Open shut-off valve in cold water supply
piping located between the air scoop and
expansion tank.
g. Allow water to overflow from bucket until
discharge from hose is bubble free for 30
seconds.
h. When zone is completely purged of air,
close zone valve or shut-off valve. Open
zone valve to the next zone to be purged.
Repeat this step until all zones have been
purged. At completion, open all zone
valves.
i. Close purge valve, continue filling the
system until the pressure gauge reads 12
psi. Close shut-off valve in cold water
supply piping.
Note - If make-up water line is equipped with
pressure reducing valve, system will
automatically fill to 12 psig.
NOTICE:
If make-up water line is equipped with
pressure reducing valve, system will automatically
fill to 12 psi. Follow fill valve manufacturer’s
instructions.
WARNING
The maximum operating pressure of this boiler
is posted on the ASME Data Label located
on the top of the boiler. Never exceed this
pressure. DO NOT plug safety or relief valve.
j. Open full port ball valve in boiler system
piping.
k. Remove hose from purge valve.
l. Confirm that the boiler and system have no
water leaks.
C. CHECK CONTROL, 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.
E. ADJUST CONTROL SETTINGS with burner
service switch turned “ON”.
1. SET ROOM THERMOSTAT about 10°F below
room temperature.
2. PRESS RED RESET BUTTON on Oil Primary
Control. Hold button for ten (10) seconds and
release to reset primary control.
3. WATER BOILERS WITHOUT TANKLESS
HEATERS The Boiler Control is factory
programmed with a High Limit setpoint of
190°F. The High Limit setpoint is adjustable
between 100°F and 220°F. This temperature
may be varied to suit the installation
requirements.
