WARNING
Fuel leak risks
• Fuel and combustion gas may flow into the room if the exhaust duct is leaking, there
is a gap due to insufficient fixing of the connection part, or if regular maintenance is
neglected. As a result, fatal hazards such as poisoning and fire explosion may occur, so
regular maintenance is recommended to check for the following:
– Cracked ducts
– Clogged ducts
– Insufficient exhaust capacity or abnormal stop of the exhaust fan of gas furnace
– Gas leak due to gas furnace heat exchanger failure (including corrosion due to poor
installation environment)
– Incomplete combustion due to gas furnace equipment failure (malfunction/parts*
failure)
* Parts refer to piping, valves, electrical wiring, electrical/electronic parts, sensors,
circuit breakers, etc.
– Short-circuit or ground fault due to ignition, tracking or insufficient insulation of gas
furnace parts
– Damage to internal and external wiring of gas furnace
– Deterioration of heat resistance, strength, corrosion resistance, insulation, etc. of gas
furnace peripheral components
– Gas furnace protection circuit malfunction
– Electrical components for electromagnetic noise interference due to normal use over
time, parts failure, and/or installation of nearby electrical devices
– Inadequate confirmation of recalled products from the design/manufacturing year of
gas furnace
– Maintaining an abnormal installation state by overlooking a gas furnace installation
error or a red tag
• If our equipment is not installed, used, or maintained as described in the PAA unit
installation/operation manual, the following problems may occur. In this case, stop the
operation immediately by turning off the power, etc., and ask the dealer or contractor for
inspection. Otherwise, gas leaks can cause poisoning, fire, explosions, water leaks, etc.,
which can cause serious bodily harm and damage to property.
– If the installation or operating environment is out of the warranty range, the control box
may malfunction, and the gas furnace protection functions may also fail and disable.
The effect of the excessive heat generated by the gas furnace can cause cracks
in the coil section resulting in refrigerant and oil leaks. Furthermore, poisoning, fire,
and explosions may occur from this, doing so can cause bodily harm and damage to
property.
• What to do if you smell gas:
– Do not try to light any appliance.
– Do not touch any electrical switch.
– Do not use any phone in your building. Immediately call your gas supplier from a
neighboring location.
– Follow the gas supplier's instructions.
– If you cannot reach your gas supplier, call the fire department.
Specifications are subject to change without notice.
