GOLD CGi Gas-Fired Water Boiler — Boiler Manual

❏

  Inspect . . .

Burners and base

The  boiler  contains  ceramic  fiber

and  fiberglass  materials.  Use  care
when handling these materials per
instructions  on

 of  this

manual.  Failure  to  comply  could
result in severe personal injury.

If insulation is damaged or displaced,

do  not  operate  the  boiler.  Replace

or  reposition  insulation  as  neces-

sary.  Failure  to  replace  damaged

insulation can result in a fire hazard,

causing severe personal injury, death

or substantial property damage.

1.  After turning off power to the boiler, remove the base

burner shield (

, item

, page 60).

.  Inspect burners and all other components in the boiler

base.

3.  If  burners  must  be  cleaned  see

below.

4.  Inspect the slotted jacket cooling openings in the bot-

tom left and right of the base pan (

, item

,

page 60).

5.  Inspect the base insulation. Pay attention to the

on  page  68  regarding  working  with  insulation

materials. Verify that the insulation is intact and secure

against all four sides of the base.

Airborne  materials,  such  as  fiberglass

and dust, are present during construc-

tion  and  remodeling.  These  materials

can be drawn in with the combustion

air and obstruct burner ports, resulting

in carbon monoxide production, a fire

hazard, or building freeze damage. Read

and  follow  the

 on  page 9.

Failure to inspect and clear gas burner

ports  could  result  in  severe  personal

injury,  death  or  substantial  property

damage.

1.  Remove burner shield and the base pan air baffle. Next

remove the pilot bracket assembly. Then remove the

four screws securing the burner tray to the manifold

and slide the burner tray out under the manifold.

.  Inspect each burner to insure that every port is com-

pletely open.

3.  If any port is not completely clear, run a vacuum at the

burner inlet while cleaning the burner ports with a wire brush. The

vacuum will help to draw any airborne material out of the burner.

4.  Reinstall components, starting with the burner tray, then the pilot

bracket assembly, burner baffle, and air inlet top and front panels.

5.  Follow the start-up procedure in the boiler manual.

Condensate drain system

1.  Inspect condensate drain fittings and tubing. Verify that condensate

can flow freely to drain.

❏

  Service . . .

Inducer motor

1.  With boiler power

, place a few drops of S.A.E. 0 motor oil in

each of the two oil cups.

Use only

to lubricate the inducer

motor.  Do  not  use  universal  household  oils.  Mo-

tor could be damaged, resulting in possible severe

property damage.

Oiled-bearing circulators

1.  The circulator shipped with the CGi boiler is water-lubricated. No

oiling is required.

.  Check other circulators in the system. Oil any circulators requiring

oil,  following  circulator  manufacturer’s  instructions.  Over-oiling

will damage the circulator.

❏

  Start-up . . .

1.  Perform all start-up procedures in Section

of this manual.

.  Verify

is correct and that fill system is working

properly.

3.  Verify

(if used) is at the right concentration and

that inhibitor level is correct.

4.

 per  manual  Sections

 and

,  verifying  no

indications of leakage and all piping and connections are in good
condition.

5.  Read the appropriate

(Section

9c

of this

manual or on boiler label) applying to the boiler.

6.  Start the boiler following the appropriate

(Section

9c

of this manual or on boiler label).
