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
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
sealing rope. If combustion chamber parts above
are badly deteriorated then replace with original
factory parts available at your distributor.
f. Use the flue brush* to clean the flue passages
and combustion chamber.
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 combustion chamber.
Vacuum the loose soot and debris from the
boiler. Clean and replace baffle plates.
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 the new one
and re-adjust electrodes. To insure proper burner
operation ONLY THE NOZZLES SPECIFIED IN
THIS MANUAL OR ON THE BURNER LABEL
SHOULD BE USED FOR REPLACEMENT.
g. 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 the four 13
mm hex head screws and tightening.
h. Replace boiler jacket front panel.
* A flue brush (triangular shape) is supplied with boiler. Replace-
ments are available from dealer or hardware stores.
CAUTION: ALWAYS KEEP THE OIL SUPPLY VALVE SHUT
OFF IF THE BURNER IS SHUT DOWN FOR AN
EXTENDED PERIOD OF TIME.
II. PROVIDING PROTECTION FOR FREEZING
Anti-freeze is sometimes used in hydronic heating
systems 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
building 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 proportions, 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

All service to the oil burner, oil filter, oil strainer, etc., should
be performed by a professionally trained service person.
Inspect and clean annually and following any period of
improper operation. Re-check and adjust settings as
specified for burner model and nozzle size. Set burner air
and draft regulator, using test instruments to obtain
recommended CO2 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 contacts, settings,
correct functioning.
C. PIPING: check piping and accessories for leaks.
D. CHIMNEY or 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
greatest in coldest weather. Refer to AIR SUPPLY,
page 3.
F. WATER SYSTEM: check
1. System to be full of water and pressure to remain
stable (between 83 kPa and 173 kPa [12 psi and
25 psi]).
2. Air-control system: noise and air binding in
radiation should not occur.
3. Water lines: slightest leaks should be corrected.
G. BOILER ROOM AIR SUPPLY: air vents should be
open and free of obstruction. See page 3.
