Burners, base and inlet air box
The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 64 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.

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.
5.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.
6.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.
