CHAPTER 1 - COMBUSTION AIR CONTAMINATION
WARNING
If the INSTINCT combustion air inlet is located
in an area likely to cause or contain contamina-
tion, or if products which could contaminate
the air cannot be removed, the combustion air
must be repiped and terminated at another lo-
cation. Contaminated combustion air will dam-
age the unit and its burner system, and can
result in substantial property damage, serious
injury, or death.
DANGER
•
Do not operate the INSTINCT if the com-
bustion air inlet is located near a laundry
room or pool facility. These areas will al-
ways contain hazardous contaminants.
•
Pool, laundry, common household, and
hobby products often contain fluorine or
chlorine compounds. When these chem-
icals pass through the burner and vent
system, they can form strong acids. These
acids will corrode the heat exchanger,
burner components, and vent system,
causing serious damage and possible
flue gas spillage or water leakage into
the surrounding area.
•
Please read the information listed below.
If contaminating chemicals are located
near the area of the combustion air inlet,
the installer must pipe the combustion
air inlet to an area free of these chemicals.
•
Failure to comply with these instructions
will result in substantial property dam-
age, serious injury, or death.
•
The INSTINCT boiler is classified as a
Category IV appliance. This utilizes un-
contaminated indoor or outdoor air for
applicance combustion. A direct vent
installation uses the outdoor air. Air sup-
ply, combusiton chamber, heat exchang-
er and evacuation of POC (products of
combustion) for this type of appliance is
sealed with respect to the room in which
the appliance is installed.
•
An in-direct installation uses uncontam-
inated indoor air for appliance combus-
tion.
•
When the air for combustion is taken
from the room an air grille must be in-
stalled by the contractor.
•
DANGER
•
•
Ensure the vent grilles are free from ob-
struction at all times. Do not be tempt-
ed to restrict or cover the air grilles as it
could cause serious injury, or death.
