Check appliance area
WARNING
To prevent potential of severe personal
injury, death, or substantial property
damage, eliminate all materials discussed
below from the boiler/water heater vicinity
and the vicinity of the boiler/water heater
combustion air inlet. If contaminants are
found:
Remove products immediately from the
area. If they have been there for an extended
period, call a qualified service technician to
inspect the appliance for possible damage
from acid corrosion.
If products cannot be removed, immediately
call a qualified service technician to
re-pipe vent and air piping and locate
vent termination/air intake away from
contaminated areas.
1. Combustible/flammable materials -- Do not store
combustible materials, gasoline or any other flammable
vapors or liquids near the appliance. Remove
immediately if found.
2. Air contaminants -- Products containing chlorine or
fluorine, if allowed to contaminate the appliance intake
air, will cause acidic condensate in the appliance. This will
cause significant damage to the appliance if allowed to
continue.
Check vent piping
1. Visually inspect the flue gas vent piping for any signs of
blockage, leakage, or deterioration of the piping. Notify
your qualified service technician at once if you find any
problems.
WARNING
Failure to inspect the vent system as noted
above and have it repaired by a qualified
service technician can result in vent system
failure, causing severe personal injury or
death.
Check pressure/temperature gauge
1. Make sure the pressure reading on the boiler pressure/
temperature gauge does not exceed 24 PSI. Higher
pressure may indicate a problem with the expansion
tank.
2. Contact a qualified service technician if problem persists.
