GOLD CGs 
❏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.
❏Start-up . . .
1.Perform all
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.
