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 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.
4. If burners must be cleaned, first remove item

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berglass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ttingsandtubing.Verify
that condensate can flow freely to drain.
