SETTING THE AIR ADJUSTMENT PLATE (See figure 13)
1. The AIR SHUTTER (A) assures complete opening of the combustion
air intake. Regulation of the combustion air flow is made by adjust-
ment of the manual AIR ADJUSTMENT PLATE (D) after loosening
the FIXING SCREWS (C and E). The initial setting of the air adjust-
ment plate should be made according to page 13.
2. The proper number on the manual AIR ADJUSTMENT PLATE (D)
should line up with the SETTING INDICATOR (B) on the fan housing
cover. Once set, the air adjustment plate should be secured in place
by tightening SCREWS C and E. Manually open and release the
air shutter to ensure it has free movement.
3. The final position of the air adjustment plate will vary on each instal-
lation. Use instruments to establish the proper settings for maximum
CO and a smoke reading of zero.

NOTE: Variations in flue gas, smoke, CO
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

EXTENDED SHUTDOWN, CLEANING OR REMOVAL OF BOILER
FROM SERVICE IN AREAS NOT SUBJECT TO FREEZING.
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
(82°C TO 93°C [180°F to 200°F]), drain water from the bottom of
the boiler until it runs clear.
B. Provide corrosion protection conditioning to the boiler water in
the heating system. There are a number of commercial heating
system preparations available from your distributor. Follow the
preparation manufactu\rer's instructions.

COMBUSTION
CHAMBER
1. For steam boilers, maintain a sodium chromate solution
strength of 250 cc/100 L (16 oz. per 50 gallons) of water; and
refill to the top of the gauge glass.
2. For water boilers, maintain a sodium chromate solution
strength of 94 cc/100 L (6 oz. per 50 gallons) of water, and refill
to normal fill-pressure with system vented.
3. Raise water temperature to at least 82°C (180°F). for one hour
to release dissolved gases.
4. Shut down burner by disconnecting the main switch.
C. To clean the fireside surfaces, first shut down burner by discon-
necting all electrical power to the burner by turning OFF the OIL
BURNER EMERGENCY SWITCH. (See IV. General Maintenance).
1. Inspect the burner combustion head. Clean if necessary and
make sure all the adjustments are correct. (See burner data
pages for the burner installed.) Replace oil nozzle with new one
and readjust electrodes. To insure proper burner operation
ONLY THE NOZZLES SPECIFIED IN THIS MANUAL OR ON
THE BURNER LABEL SHOULD BE USED FOR REPLACE-
MENT.
2. Protect all of the fireside surfaces by swabbing with neutral
mineral oil.
3. Close main cast iron burner door (door on which burner is
mounted). Make sure that the entire seal (fiberglass rope) is
making good contact with the boiler casting when replacing
3/8-16 x 25 mm (1") long hex head bolt and tightening.
4. Check the flue collector seal. This is the flat rope seal on top of
the heat exchanger. The rope must be in place adjacent to the
long bosses on front and rear sections and adjacent to the
short bosses on the intermediate sections. The rope should be
directly under the flue collector flanges when the flue collector
is replaced. Use the two 1/4-20 x 19 mm (
screws to fasten the flue collector. In order to assure a proper
seal be sure that the flue collector is compressing the flat rope
and not hanging up on the section bosses. Tighten the two
screws.
D. If boiler room is damp, provide ventilation.
II. Water Treatment
Treatment for boiler feed water should be considered in areas of
known problems, such as where a high mineral content and
hardness exist. Antifreeze may be added to the system water to
protect the system. Please adhere to the specifications given by
the antifreeze manufacturer. Do not use automotive, ethylene
glycol, undiluted or petroleum-based antifreeze. Personal injury,
death or property damage can result. Inhibited propylene glycol,
especially made for hydronic systems, is recommended. An
antifreeze/water mixture may require a backflow preventer within
the automatic water feed piping. Check that components such
as diaphragm expansion tanks, radiation, pumps etc. are suit-
able for and sized for use with glycol A 40% antifreeze content
normally will provide freeze-up protection to -10°F / -23°C. A
50% solution will normally provide freeze-up protection to about
-30°F / -34°C.
Note:
• Do not use antifreeze other than specifically made for hot water
heating systems.
• System may contain components which might be negatively
affected by antifreeze.
I.
• Check total system frequently when filled with antifreeze.
• Advise system operator and/or owner that system is filled with a
glycol mix.
• Follow antifreeze manufacturer's instructions.

III. OIL BURNER

Inspect and clean annually and following any period of improper
operation. Recheck and adjust settings as specified for burner
model and nozzle size. Set burner air and draft regulator, using test
instruments to obtain recommended CO
