USERS INFORMATION MANUAL
OIL-BURNING EQUIPMENT:
STEAM AND HOT-WATER BOILERS
IMPORTANT
• READ AND SAVE THESE INSTRUCTIONS FOR
REFERENCE.
• USE ONLY NUMBER 2 FUEL OIL.
! CAUTION
!
• DO NOT USE GASOLINE, CRANKCASE DRAININGS,
OR ANY OIL CONTAINING GASOLINE.
• NEVER BURN GARBAGE OR PAPER IN THE UNIT,
AND NEVER LEAVE COMBUSTIBLE MATERIAL
AROUND IT.
! WARNING !
• KEEP YOUR BOILER AND THE SPACE AROUND
THE APPLIANCE CLEAR OF DEBRIS. DO NOT
STACK ITEMS ON OR AROUND THE APPLIANCE
WITHIN THE REQUIRED CLEARANCES TO
COMBUSTIBLES.
• ENSURE THAT THE SUPPLY OF COMBUSTION
AIR TO THE APPLIANCE IS NOT OBSTRUCTED
OR CUT OFF. ENSURE THAT THE PROPER
VENTILATION TO THE APPLIANCE AREA IS
MAINTAINED.

INSTRUCTIONS TO OBTAIN PROPER
OPERATION OF THE BOILER
! CAUTION !
• DO NOT START THE BURNER UNLESS ALL
CLEAN-OUT DOORS ARE SECURED IN PLACE.
• DO NOT ATTEMPT TO START THE BURNER
WHEN THE COMBUSTION CHAMBER HAS
ACCUMULATED OIL, OR IS FULL OF VAPOR, OR
IS VERY HOT.
Instruments are the only reliable method to determine proper air
adjustments. An improperly adjusted burner causes soot and
high fuel bills because of incomplete combustion of the fuel oil.
This in turn may require excessive boiler maintenance, service
costs, and in some instances, house cleaning or redecorating.
A competent service mechanic should be consulted to make the
proper adjustments with a smoke tester, CO2 indicator and draft
gauge. Bacharach or Dwyer test kits include these instruments.
A ¼” diameter slot is provided in the inspection cover plate to
take draft readings in the combustion chamber. A ¼” diameter
hole will be required in the flue pipe between the boiler and
barometric damper (if used) to take draft, CO2, smoke and
temperature readings. Adjust air shutter on oil burner to obtain
a “trace” of smoke. Measure CO2 at this point. Increase air
adjustment to lower CO2 approximately one (1) percent. Check
to ensure zero (0) smoke and correct draft is obtained for
the unit installed (reference the Boiler Installation Manual for
correct draft settings). If the proper draft can not be maintained,
changes and/or modifications may be required in the venting,
chimney or combustion air supply.

SHUTTING DOWN THE BOILER FOR
EXTENDED PERIODS OF TIME
! CAUTION !
ALWAYS KEEP THE OIL SUPPLY VALVE SHUT OFF
IF THE BURNER IS SHUT DOWN FOR AN EXTENDED
PERIOD OF TIME.
• Always turn off electrical power to the boiler via the field
installed fused disconnect switch if the boiler is shut down
for an extended period of time.
• When restarting the boiler from an extended shutdown,
follow the Operating Instructions in the Installation Manual
and Operating Instructions.
GENERAL MAINTENANCE DURING OPERATION
The following preventative maintenance should be performed
by a qualified service technician annually prior to the heating
season.
Preventative maintenance of an oil fired boiler reduces
operating costs. The boiler and vent pipe should be inspected
for accumulation of soot or scale deposits periodically but at
least once every year before the start of each heating season.
When soot is present on the section walls and flue ways,
improper combustion will result, causing additional sooting and
scaling until flue ways are completely closed.
Periodic inspection and tightening of the tank-less heater/cover
plate bolts, if applicable, will reduce the risk of leaks.
! WARNING !
ALWAYS DISCONNECT POWER TO THE BOILER WITH
THE EMERGENCY POWER ISOLATION SWITCH WHEN
SERVICING THE BOILER. THE EMERGENCY POWER
ISOLATION SWITCH IS FIELD INSTALLED AND SHOULD
BE WITHIN 5 FEET OF THE BOILER.

OIL BURNER MAINTENANCE
1. Oil Burner Motor – Refer to burner manual provided with
boiler.
2. Fuel Filter – Replace to prevent contaminated fuel from
reaching nozzle. Partially blocked fuel filter can cause
premature failure of fuel pump.
3. Fuel Pump Unit – Replace pump screen and clean pump
unit to maintain fuel delivery to nozzle.
4. Ignition Electrodes – Clean and adjust per manufacturer’s
recommendations, to maintain reliable ignition of oil.
5. Nozzle – Replace to maintain safe and reliable combustion
efficiency. Replace with nozzle as required in charts located
in this manual
6. Fan and Blower Housing – Must be kept clean, free of dirt,
lint and oil to maintain proper amount of air fuel requires to
burn.
7. Check Final Burner Adjustments.
BOILER CLEANING INSTRUCTIONS
1. Shut off all electrical power to the boiler/burner and shut off
fuel supply
2. Remove vent pipe from top of boiler. Inspect pipe and
chimney for signs of corrosion and deterioration. Clean out
base of chimney. If vent pipe shows any signs of corrosion
or deterioration, replace it immediately. If chimney damage
or deterioration is discovered, contact a service technician.
3. Remove top jacket panel screws (5), brass wing nuts (2)
holding flue collector top, and flue collector top. Inspect gasket
on underside of flue collector and replace as necessary.
4. Before beginning to clean flue passageways, insure
combustion chamber blanket is covered. If blanket is not
covered prior to cleaning, replace blanket once cleaning is
completed.
5. With access to flue passageways, remove soot from fireside
surfaces by brushing diagonally through flue passages (see
drawing below). Brushing can be made easier by cutting end
of flue brush off and inserting it into drill. When brushing,
take care to not damage target wall with flue brush or to damage
the combustion chamber with the flue brush.

BOILER CLEANING INSTRUCTIONS
6. Carefully vacuum soot accumulations from combustion
chamber area, take care to not damage any of refractory or
blanket insulation. To gain access to combustion chamber
first check that shut off valve on fuel oil line is closed and
disconnect fuel oil line. Open swing door by removing whiz
lock nut holding door shut.
7. Inspect target wall, fire door refractory, and combustion
chamber blanket (when included) for cracking and
deterioration. If there are signs of cracking or deterioration,
replace refractory or blanket before reassembling burner /
front plate.
8. Inspect door’s braided gasket for wear and damage. Replace
when necessary with braided gasket of same material and
size.
9. Use caution when vacuuming in the chamber area. Damage to
chamber could result.
10. Reinstall the burner.
11. Reinstall the flue collector.
12. Reinstall top jacket panel. Reconnect flue pipe.
13. Reconnect electrical and fuel supplies.
14. Fire burner, check for proper combustion using combustion test
equipment, make adjustments as necessary.
15. Verify all safety controls and operating controls are functioning
properly.
INSTRUCTIONS FOR BLOW DOWN OF
A STEAM BOILER
Before blowing down the boiler, fill it to the water line. Turn in burner
and allow five pounds of steam pressure to build up. Run a temporary
connection from one of the drain valves to a nearby sewer. Connect
to a drain valve on the opposite end of the boiler from the feed water
inlet, if possible. Shut off the oil burner, open drain valve and blow
down the entire contents of boiler.
! WARNING !
WATER WILL BE BOILING HOT.
5
USERS INFORMATION MANUAL
Allow boiler to thoroughly cool and slowly refill to water line. Repeat as
many times as required until blow off water is clear. Owner should blow
down boiler at least once each month of the heating season.
Contact a qualified service technician before remodeling, for annual
service/maintenance, before extended periods of shutdown, and before
start-up.
! CAUTION !
DO NOT TAMPER WITH THE UNIT OR CONTROLS –
CALL YOUR QUALIFIED SERVICE TECHNICIAN.
