6. Remove the Baffles from between the casting sections. Use
the flue brush to clean the pinned flue ways between the
sections.† 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.
Reinstall all flue Baffles between the casting sections.
7. 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.
8. Protect all of the fireside surfaces by swabbing with neutral
mineral oil.
9. 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 1” long hex head bolt and tightening.
10. Check the flue collector seal. This is the High Temp. silicone
seal on top of Flue Collector base. The seal must be in place
over the 10-32 Studs. Use the 10-32 Hex Nuts to refasten the
flue collector top. In order to assure a proper seal be sure that
the seal is pressed tight between the flue collector base and
top. Be careful not to over tighten the 10-32 nuts as this will
cause the flue collector to become distorted.
C. If boiler room is damp, provide ventilation.
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 pro-
tect 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 tankless 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 Institute, 35 Russo
Place, Berkeley Heights, N.J. 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 strainers, etc., should be
performed by a professionally trained service person.
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 instru-
ments to obtain recommended CO2 and draft without smoke.
Refer to page 5.
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 obstruc-
tions 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 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.
4. Low water cut-off, for operation (see instructions furnished
with unit). See page 9.
G. BOILER ROOM AIR SUPPLY: air vents terminal should be open
and free of obstruction. See page 3.
† A flue brush (2-1/4" dia.) is supplied with boiler. Replacements
are available from dealer or hardware stores.
