Check for:
Eliminate all system leaks.
Continual fresh makeup water
will reduce boiler life. Minerals
can build up in sections, reduc-
ing 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 im-
mediately. Do not start boiler
again until corrected. Failure to
comply could result in severe
personal injury, death or sub-
stantial 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.

Start the boiler
Follow the Lighting/Operating Instructions from
Section 8 or 9 to start the boiler. Remove boiler
jacket door and note the gas valve manufacturer
and model number. Use only the lighting/operat-
ing instruction which applies to this gas valve (see
Table 5, page 30). (The lighting instruction label on

Check system and boiler
1. Check system piping for leaks. If found, shut
down boiler and repair immediately.
2.
Vent air from system using manual vents. Air in
the system will interfere with circulation and cause
heat distribution problems and noise.
3. 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.
4. Check around the boiler for gas odor following the
procedure of Section 6a of this manual.
5. Verify operation per Section 6d. Perform check-out
procedure in Section 7 and fill in the Installation
and service certificate on the same page.
