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.

draining hot water from a boiler. Scalding water and/or
chemicals can cause permanent 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 EMER-
GENCY 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. Provide corrosion protection conditioning to the boiler
water in the heating system. There are a number of com-
mercial heating system preparations available from your
distributor. Follow the preparation manufacturer's instruc-
tions.
C. To clean the fireside boiler surfaces, first shut down
burner by disconnecting all electrical power to the burn-
er 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 chimney
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 both13 mm
hex head screws on the sides of the swinging door. You
will need a 13 mm 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 seal-
ing 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 [(3) baffle plates in EC-13,
(2) baffle plates in EC-14 & 15, (0) baffle plates in EC-
16.]† A wire brush 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 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 SPECI-
FIED IN THIS MANUAL OR ON THE BURNER LABEL
SHOULD BE USED FOR REPLACEMENT.
† A flue brush (triangular shape) is supplied with boiler.
Replacements are available from dealer or
hardware stores.
7.Protect all of the fireside surfaces by swabbing with neu-
tral mineral oil.
8.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 both 13 mm hex head screws and tightening.
D. If boiler room is damp, provide ventilation.
