Combustible / flammable materials - Do not
store combustible materials, gasoline or
other flammable vapors or liquids near the
unit. Remove immediately if found.
Air contaminates - Products containing chlo-
rine or fluorine, if allowed to contaminate the
combustion air, will cause acidic condensate
within the unit. This will cause significant
damage to the unit. Read the list of potential
materials listed on page 2 of this manual.
If any of these products are in the room
from which the unit takes its combustion air,
they must be removed immediately or the
combustion air intake must be relocated to
another area.
Check Combustion Air Inlets
• Verify that ventilation air openings to the
mechanical room are open and unob-
structed.
• Verify that the unit’s vent termination
and combustion air intake are clean and
free of obstructions. Remove any debris
on the air intake or flue exhaust open-
ings. If removing the debris does not
allow the unit to operate correctly, con-
tact your qualified service technician to
inspect the unit and the vent / combus-
tion air system.
Check Temperature Display and Pressure
Gauge
• Ensure the pressure reading on the
pressure gauge does not exceed 25
psig. Higher pressure readings may indi-
cate a problem with the expansion tank.
• Ensure the temperature on the display
panel does not exceed 194 ºF. Higher
temperature readings may indicate a
problem with the operating thermostat
controls.
• Contact a qualified service technician if
problem persists.
