GOLD CGs Gas-Fired Water Boiler — Boiler Manual
❏ Inspect . . .
Burners, base and inlet air box
The boiler contains ceramic fiber and fiberglass
materials. Use care when handling these materials
per instructions on page 68 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 inlet air box top panel
(Figure 27, item 13, page 56).
2. Inspect gasket (item
14). Replace if necessary.
3. Inspect burners and all other components in the inlet air box and boiler
base.
4. If burners must be cleaned, first remove item
11, Figure 27, page 56.
Access the burner assembly by first removing burner baffle, item 4. Then
remove the screws securing the burner tray to the manifold. Slide the
burner tray out. Follow Burner cleaning instructions below to clean
burners thoroughly.
6. Inspect the base insulation. Pay attention to the
WARNING on page 64
regarding working with insulation materials. Verify that the insulation
is intact and secure against all four sides of the base.
7. Replace all components when service has been completed.
Burner cleaning instructions
Airborne materials, such as fiberglass and dust, are pres-
ent during construction and remodeling. These materi-
als 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 WARNING on page 9. Failure to inspect and clear
gas burner ports could result in severe personal injury,
death or substantial property damage.
1. Inspect each burner to insure that every port is completely open.
2. 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.
3. Follow instructions above to replace all components after cleaning.
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 off, place a few drops of S.A.E.
20 motor oil in each of the two oil cups.
Use only S.A.E. 20 motor oil to
lubricate the inducer motor. Do not
use universal household oils. Motor
could be damaged, resulting in pos-
sible severe property damage.
Oiled-bearing circulators
1. The circulator shipped with the CGs boiler is water-
lubricated. No oiling is required.
2. Check other circulators in the system. Oil any
circulators requiring oil, following circulator man
-
ufacturer’s instructions. Over-oiling will damage the
circulator.
❏ Start-up . . .
1. Perform all start-up procedures in Section 7 of this
manual.
2. Verify
cold fill pressure is correct and that fill system
is working properly.
3. Verify
antifreeze level (if used) is at the right con-
centration and that inhibitor level is correct.
4. Check gas piping, per manual Sections 5 and 7,
verifying no indications of leakage and all piping
and connections are in good condition.
5. Read the
Operating instructions (Section 9c of this
manual or on boiler label) applying to the boiler.
6. Start the boiler following the
Operating instruc-
tions (Section 9c of this manual or on boiler label)
and manual Section 7.
