CARE AND MAINTENANCE

This section must be brought to the attention of the owner by
the installer so that the owner can make the necessary arrange-
ments with a qualified service agency for the periodic care and
maintenance of this boiler. The installer must inform the owner
that the gas supplier can recommend a number of qualified ser-
vice agencies. The installer must also inform the owner that the
lack of proper care and maintenance of this boiler and any fuel
burning equipment may result in a hazardous condition.
A. GENERAL MAINTENANCE (Refer also to User's Information
Manual)
These operations are recommended to be performed at reg-
ular intervals:
1. BOILER HEATING SURFACES: clean off all coatings
found.
2. BOILER CONTROLS: check contacts, settings, correct
functioning.
3.PIPING: check piping and accessories for leaks.
4. CHIMNEY and BREECHING: check for obstructions and
leaks.
5. BOILER ROOM AIR SUPPLY: check air vents for continued
POSITIVE supply of air as required. Air needs are greatest
in cold weather. Air vents must be open and free of
obstruction.
WARNING: THE FLOW OF COMBUSTION AND VENTILATING
AIR TO THE BOILER SHOULD NOT BE OBSTRUCTED.
6. WATER SYSTEM: check:
i. System to be full of water, and pressure to remain stable
at correct setting on gauge.
ii. Air-control system: noise and air binding in radiation
should not occur.
iii.Water lines: slightest leaks should be corrected.
iv.Low water cut-off, for operation (see instructions
furnished with unit).
WATER LEVEL CHECK DURING HEATING SEASON:
A.Check water level regularly and add water slowly to
system when needed. If much water is added, venting may
be necessary.
B.Regular loss of water from water boiler system may
indicate either a system leak, or a faulty air-control system,
or a faulty automatic fill valve.
ANNUAL INSPECTION AND CLEANING:
A.It is important that this boiler be inspected by a competent
serviceperson to help insure safe and reliable operation.
B.Check for gas leaks from valve and gas piping to burners
and pilot. If leaks are found, repair or replace as required.
C.This inspection should include:
1. Controls check. See SAFETY CHECK, IV.
2. Recheck of input gas rate to burners. See "Initial Start"
paragraph in "Operating Instructions" section.
3. Re-adjusting for best flame characteristics of main flame
and pilot(s).
See "Initial Start" paragraph in "Operating Instructions"
section and see "Burner Adjustment" section.
4. Burner and boiler flue passage cleanliness: BURNER
AND FLUE CLEANING (see sketch). It is suggested that
paper be placed on burners to collect any foreign mater-
ial in cleaning flues.
Remove draft hood, jacket top and flue cover.
Use wire brush to clean flueways.
Replace flue cover and re-seal with furnace cement.
Replace jacket top and draft hood and reconnect to
smoke pipe, using screws. Remove and dispose of
paper and accumulated material.
If burner surfaces are not clean, or if uneven flame indi-
cates plugged burner ports, remove and clean burners.
TO REMOVE BURNERS:
A.Remove burner clip at orifice.
B.Disconnect pilot at pilot mount, or disconnect thermo -
couple and pilot gas line at gas valve, before removing
burners next to pilot.
C.Lift rear of burner and slide forward to free orifice end and
remove.
D.Clean and replace burners* and pilot. Adjust burners as
described on page 13.
* To clean burners run a clean flue brush up the tube until
all foreign matter is removed.

SAFETY CHECK FOR CONTROL SYSTEM

A. 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 main gas valve should close automatically. If
the high limit does not close the main gas valve, the valve,
the high limit or the wiring is faulty. Repair or replace
immediately.
B. Gas valve safety shutdown test:
1. For boiler equipped with constant burning pilot, with main
burners firing, disconnect the thermocouple or thermopile
generator from the gas valve. The gas valve should Imme-
diately shut off the main burners and the pilot.
2. For boilers equipped with Honeywell S8600 inter mittent
pilot system, with main burners firing, disconnect the igni-
tion cable from the S8600 IGNITOR BOX. The gas valve
should shut off the main burners.
C. Check for gas leaks from valve and gas piping to burners and
pilot. If leaks are found, repair or replace as required.
PROVIDING PROTECTION FROM FREEZING.
Anti-freeze is sometimes used in hydronic heating systems to
protect against freeze-up in the event of power failure or control
shutdown when the building is unoccupied. It should be recog-
nized that unless the building is kept above freezing tempera-
ture by some means, the plumbing system is not protected.
Two types of anti-freeze may be used: ETHYLENE GLYCOL,
used in automobiles, has desirable properties, but is toxic. Its
use may be prohibited when system water/glycol solution is in
contact with a potable water vessel (as with a tankless heater).
PROPYLENE GLYCOL is used in the quick-freeze food industry;
it is practically non-toxic. Its use may be permitted when tank-
less heaters are used. When anti-freeze must be used, inhibited
propylene glycol is recom mended. Useful information on the
characteristics, mixing proportions, etc. of glycol in heating sys-
tems is given in Technical Topics No. 2A, available from the
Hydronics Institute 34 Russo Place, Berkeley Heights, NJ
07922. Consult glycol manufacturers for sources of propylene
glycol.
