draining hot water from a boiler. Scalding water and/or
chemicals can cause permanent injury to the skin, eyes
and respiratory system.
II. Filling and venting the water boiler after cleaning
A. Refill the system with fresh water.
B. Bring water temperature to at least 180° F promptly.
C. Circulate water through entire system.
D. Vent the system, including the radiation.
E. The boiler is now ready to be put into service or on
standby.
F. If brand name air-control devices are used, venting
instructions furnished with the devices should
be followed.
III. Safety check for control system
High limit control test: Set thermostat high enough for boiler
water temperature to reach high limit control setting. When
this temperature is reached, the high limit switch should
open, and the burner should shut off automatically. If the
high limit does not operate to shut off the burner, the high
limit or the wiring is faulty. Repair or replace immediately.

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 manufacturer's instructions.
C.To clean the fireside boiler surfaces, first shut down
burner by disconnecting 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 thoroughly.
2. Inspect the entire vent connector back to the chim-
ney and clean if necessary.
3. Inspect the chimney for soot, debris and other unsafe
conditions of the chimney and take the necessary
action.
4. The burner mounting door must be fully open to
clean the flue passages and the combustion
chamber. If the oil line is not flexible enough it should
be disconnected from the burner during the cleaning
process. The flexible electric 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 both 16 mm (5/8") special nuts on the sides
of the swinging door. You will need a 16 mm (5/8") open
end or box wrench. Open the door to completely
expose the combustion chamber for thorough
cleaning and for inspection of 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.
5. Use the flue brush to clean the flueways. Remove cast
iron baffle plates for cleaning See figure 5 for removal
and replacement of baffle plates. A wire brush (sup-
plied with boiler) may be used to remove any carbon
accumulation that may have developed in the combus-
tion chamber. Vacuum the loose soot and debris from
the boiler. Replace baffle plates.
6. Inspect the burner combustion head. Clean if neces-
sary and make sure all the adjustments are correct.
(See burner data pages for the burner installed.)
Replace oil nozzle with new one and readjust elec-
trodes. To insure proper burner operation ONLY THE
NOZZLES SPECIFIED IN THIS MANUAL OR ON
THE BURNER LABEL SHOULD BE USED FOR
REPLACEMENT.
