I. EXTENDED SHUTDOWN, CLEANING OR REMOVAL OF
B
OILER FROM SERVICE.
DANGER: Use CAUTION when handling chemicals and
d

a
ining hot w
a
ter from a boiler
. S
calding w

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
t
he 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 commercial
heating system preparations available from your distributor.
Follow the preparation manufacturer’s instructions.
C.T
o 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 all four 13 mm hex head screws on the
sides of the s
winging door. You will need a 13 mm
open end or box wrench. Open the door to
completely e
xpose the comb
ustion chamber for
thorough cleaning and f
or inspection of main cast
iron burner door insulation and burner door fiberglass
sealing rope.
5. Use the flue br
ush to clean the fluew
a
ys
. Remove cast
iron baffle plates for cleaning [(2) baffle plates in EC-
13, (0) baffle plates in EC-14, 15, and EC-16.]† A wire
brush may be used to remove any carbon accumula-
tion that may ha
v
e de
v
eloped in the combustion cham-
ber
.
V
acuum 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 b
ur
ner data pages f
or 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.
† A flue brush (triangular shape) is supplied with boiler.

. Protect all of the fireside surf
a
ces
b
y swabbing with
neutral mineral oil.
8. Close main cast iron b
urner 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 four 13 mm hex head
s
crews and tightening.
D.If boiler room is damp, provide ventilation.
II. PROVIDING PROTECTION FOR FREEZING
Anti-freeze is sometimes used in hydronic heating sys-
tems to protect against freeze-up in the event of power
failure, or safety control shutdown when the building is
unoccupied. It should be recognized that unless the build-
ing is kept above freezing temperature by some means,
the plumbing system is not protected.
PROPYLENE GLYCOL is used in the quick-freeze food
industry; it is practically non-toxic. Its use may be permitted
when indirect water heaters are used. When anti-freeze
must be used, inhibited propylene glycol is recommended.
Useful information on the characteristics, mixing propor-
tions, etc. of glycol in heating systems is given in Technical
Topics No. 2A, available from the Hydronics Division of
GAMA, 35 Russo Place, Berkeley Heights, NJ 07922.
Consult glycol manufacturers for sources of propylene
glycol.
DO NOT USE ETHYLENE GLYCOL BECAUSE IT IS TOXIC.
III. OIL BURNER
Inspect and clean annually and following any period of
improper operation. Recheck and adjust settings as speci-
fied for burner model and nozzle size.
Set burner air using test instruments to obtain recommend-
ed CO
2
and draft without smoke. See the Burner Data
page in this manual that corresponds to the burner
installed.
IV. GENERAL MAINTENANCE
These operations are recommended to be performed at
regular intervals:
A.BOILER HEATING SURFACES: clean off all coatings
found. Reseal covers.
B.BOILER CONTROLS: check settings, correct functioning.
C.PIPING: check piping and accessories for leaks.
D.STUB VENT and BREECHING: check for obstructions
and leaks.
E.COMBUSTION AIR TO BURNER: check for continued
POSITIVE supply of air as required. Air needs are great-
est in coldest w
eather.

ATER SYSTEM: check
1. System to be full of water and pressure to remain
stable (between 12 psi and 25 psi).
2.
Air-control system:
noise and air binding in r
adiation
should not occur
.
3. Water lines: slightest leaks should be corrected.
G.BOILER ROOM AIR SUPPLY: air vents should be open
and free of obstr
uction.
