1.0 Combustion Air - Prevention of Contamination
4
SECTION I - COMBUSTION AIR -
PREVENTION OF CONTAMINATION
If the PRESTIGE combustion air inlet is located in
any area likely to cause or contain contamination, or
if products, which would contaminate the air cannot
be removed, the combustion air must be re-piped
and terminated to another location. Contaminated
combustion air will damage the unit and its burner
system, resulting in possible severe personal injury,
death or substantial property damage.
Do not operate a PRESTIGE unit if its combustion air
inlet or the unit is located in or near a laundry room
or pool facility. These areas will always contain haz-
ardous contaminates.
Pool and laundry products and common household
and hobby products often contain fluorine or chlo-
rine compounds. When these chemicals pass
through the burner and vent system, they can form
strong acids. These acids can create corrosion of
the heat exchanger, burner components and vent
system, causing serious damage and presenting a
possible threat of flue gas spillage or water leakage
into the surrounding area.
Please read the following information. If contami-
nating chemicals will be present near the location of
the combustion air inlet, the installer should pipe the
combustion air inlet to another location per the
PRESTIGE installation manual.

mechanical room are open and unobstructed.
2. Verify that the unit’s vent termination and com-
bustion air intake are clean and free of obstruc-
tions. Remove any debris on the air intake or
flue exhaust openings. 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 / combustion air system.
3.1.3 Check Temperature Display and
Pressure Gauge
1. Ensure the pressure reading on the pressure
gauge does not exceed 25 psig. Higher pres-
sure readings may indicate a problem with the
expansion tank.
2. Ensure the temperature on the display panel
does not exceed 194ºF. Higher temperature
readings may indicate a problem with the oper-
ating thermostat controls.
3. Contact a qualified service technician if prob-
lem persists.

gases can be emitted into the surrounding area
causing severe personal injury or death.
2. While the unit is running, check the discharge
end of the condensate drain tubing. Ensure no
WARNING
WARNING
flue gas is leaking from the condensate drain
tubing by holding your fingers near the opening.
3. If you notice flue gas leaking this indicates a dry
condensate drain assembly. Fill the condensate
drain assembly with water. Contact a qualified
service technician to inspect the unit and con-
densate line and refill the condensate drain
assembly if problem persists regularly.
4. Ensure the condensate drain line is not blocked
by pouring water through the fill plug port on the
