Operate the boiler
Start the boiler
1. Check boiler water level — Should be approximately ½ way
up gauge glass.
2. Remove boiler jacket door and note the gas valve manufacturer
and model number.
3. Follow the appropriate Operating Instructions found in the GSA
Spark Ignition Control Supplement. (The Operating Instruction
label on the boiler provides the same information.)
3. If boiler fails to start, see “If boiler doesn’t start . . . Check for:”
on this page.
Check system and boiler
Eliminate all system leaks. Continual fresh makeup
water will reduce boiler life. Minerals can build up
in sections, reducing heat transfer, overheating cast
iron, and causing section failure.
If you discover evidence of any gas leak, shut down
the boiler at once. Find the leak source with bubble
test and repair immediately. Do not start boiler again
until corrected. Failure to comply could result in
severe personal injury, death or substantial property
damage.
Do not use petroleum-based cleaning or sealing
compounds in boiler system. Severe damage to
boiler will occur, resulting in substantial property
damage.
1. Check system piping for leaks. If found, shut down boiler and
repair immediately.
2. Inspect vent system thoroughly for signs of deterioration from
corrosion, physical damage or sagging. Verify that masonry
chimney liners are in good condition, with no obstructions,
and there are no openings into the chimney.
3. Check around the boiler for gas odor following the procedure
of “Check for gas leaks”, page 17.
4. Verify operation using procedures below. Perform “Checkout
procedure”, page 20, and fill in the “Installation and service
certificate”.
If boiler doesn’t start . . . Check for:
1. Loose connections, blown fuse or service switch off?
2. High limit switch set below boiler pressure?
3. Thermostat set below room temperature?
4. Gas not turned on at meter or boiler?
5. Incoming gas pressure less than:
5” w.c. for natural gas? 11” w.c. for propane gas?
6. If none of the above corrects the problem, see “Troubleshoot-
ing”, in the GSA Spark Ignition Control Supplement.
DO NOT proceed with boiler operation unless
boiler and system have been filled with water
and all instructions and procedures of previous
manual sections have been completed. Failure to
do so could result in severe personal injury, death
or substantial property damage. Before starting the
boiler . . .
• See Spark Ignition Control Supplement for Operat-
ing Instructions
• Verify the boiler and system water level is correct (no
more than ½ of gauge glass or less than ¼” above
bottom of gauge glass).
• Verify the “Preparation” procedures, on previous
page, have been completed.
