GOLD CGa Gas-Fired Water Boiler — Boiler Manual

Start-up — if boiler doesn’t start . . .

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.

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?

. If none of the above corrects the problem, refer to

Troubleshoot-

ing

Section

of this manual.

1. Loose connections, blown fuse or

service switch off?

. High limit switch set below boiler

water temperature?

3. Thermostat set below room tem-

perature?

Start-up — operate boiler

(continued)

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

the boiler provides the same information.)

• See

Section 6c

if boiler fails to start.

Check system and boiler

Check system piping for leaks.

If found, shut

down boiler and repair immediately.

Vent air from system

using manual vents. Air in

the system will interfere with circulation and cause
heat distribution problems and noise.

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.

Check around the boiler

for gas odor following the

procedure of Section

of this manual.

Verify operation

per Section

. Perform check-out

procedure in Section

and fill in the

Installation

and service certificate

on the same page.
