pop safety valve and re-pipe boiler as shown in Figure B
below, making sure to reinstall pop safety valve on tee to
complete the blow off connection.
2. Connect a length of pipe to the elbow and place a bucket
underneath the open end of the pipe, cover bucket with a
piece of cloth.
3. Open the SKIMMER drain valve with caution. DO NOT
open the boiler drain valve. Fill the boiler slowly until
water begins to seep into the bucket from the skimmer
drain blow-off connection. Fire the boiler. Allow water to
heat up while water seeps into the bucket. Maintain that
water level necessary just to be able to continue skim-
ming. Continue until water is clean and no oil can be
seen floating in the bucket. Empty bucket frequently in
order to see if the water is clean.
4. Repeat this process until all film is skimmed off, lower the
water level to 648 mm (25
er (see Figure B). When all surging has stopped, turn off
the boiler, remove skimmer valve and plug the tee. Check
the pop safety valve for proper operation.
5. The entire process may have to be repeated over a peri-
od of a few days on extremely fouled systems.
C. CLEANING PIPING SYSTEM
1. To clean piping system, open all valves at the heating ele-
ments, after getting up a good head of steam, shut the
boiler down and allow the condensate to return to the
boiler. The condensate will carry the oil film with it. Again
blow-off the boiler. On extremely fouled systems, it may
require several visits over a period of a few days to clean
the system.
2. When steam only (no water) is released through the hand
valve, the boiler will not surge or flood.

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
arrangements 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 service 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 haz-
ardous condition.
A. GENERAL MAINTENANCE (Refer also to User's Information
Manual)
These operations are recommended to be performed at
regular 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 contin-
ued 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 sta-
ble 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
material 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.
