SETTING THE AIR DAMPER ADJUSTMENT (see figure 10 & picture 2)
1. The initial air damper setting is made by turning screw (2) until the top edge of the air damper (3) is aligned with the
number according to the burner setup chart.
2. Further adjustments can be made with the burner cover in place by removing plastic plug on the top right hand side
of the cover. Turn the screw counter clockwise (+ indicator) to increase combustion air, turn the screw clockwise ( -
indicator) to decrease combustion air.
3. The final position of the air damper will vary on each installation. Use instruments to establish the proper settings
for maximum CO2 and a smoke reading of trace to zero.
NOTE: Variations in flue gas, smoke, CO2 and temperature readings may be experienced when the burner cover
is put in place. Therefore, the burner cover MUST be in place when making the final combustion instrument
readings, to ensure proper test results.

CARE AND MAINTENANCE
CAUTION: DO NOT ATTEMPT TO START THE BURNER WHEN
EXCESS OIL HAS ACCUMULATED, WHEN THE UNIT IS FULL OF
VAPOR, OR WHEN THE COMPBUSTION CHAMBER IS VERY HOT.
CAUTION: DO NOT TAMPER WITH THE UNIT OR CONTROLS –CALL
YOUR SERVICE PERSONNEL.
I. EXTENDED SHUTDOWN, CLEANING OR REMOVAL OF BOILER
FROM SERVICE.
DANGER:
Use CAUTION when handling chemicals and draining hot
water from a boiler. Scalding water and/or chemicals can cause per-
manent injury to the skin, eyes and respiratory system.
A. Shut down burner by disconnecting all electrical power to the burner
by turning OFF the BURNER EMERGENCY SWITCH of this boiler.
After shutting down burner, while the boiler is still hot (180°F to
200°F), drain water from the bottom of the boiler until it runs clear.
B. To clean the fireside boiler surfaces, first shut down burner by dis-
connecting all electrical power to the burner by turning OFF the OIL
BURNER EMERGENCY SWITCH of this boiler in order to perform
the following work in (1) through (10) below.
1.
Remove the flue pipe from the boiler flue collar and clean thor-
oughly.
2. Inspect the entire vent connector back to the chimney and
clean if necessary.
3. Inspect the chimney for soot, debris and other unsafe condi-
tions of the chimney and take the necessary action.
4. Remove the flue collector by first removing the top jacket panel.
The flue collector is held in place by a 10-32 Hex Nuts
Remove the Hex Nuts and carefully remove the flue collector.
Try not to disturb the seal under the flue collector.
5. When necessary to clean the combustion chamber you must
first CLOSE the suction valve (and return valve if two pipe).
Then disconnect the oil lines from the burner. The flexible elec-
tric conduit connected from the junction box on the boiler to the
burner via a plastic connector must be disconnected from the
burner by grasping the plastic half of the connector closest to
the flexible conduit and gently pulling it in the direction of the
conduit until it is disconnected. Remove the single 3/8-16 hex
head screw on the LEFT side of the swinging door. You will
need a 9/16” drive socket. Open the door to completely expose
the combustion chamber for thorough cleaning and for inspec-
tion of target wall, blanket (provided in certain models; see rat-
ing plate), main cast iron burner door insulation and burner
door fiberglass sealing rope. If combustion chamber parts
above are badly deteriorated then replace with original factory
parts available at your distributor.
