CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.6. Combustion Air Contamination
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 anoth-
er location. Contaminated combustion air will
damage the unit and its burner system, and
can result in substantial property damage, se-
rious injury, or death.
• 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
chemicals pass through the burner and
vent system, they can form strong ac-
ids. These acids will corrode the heat ex-
changer, burner components, and vent
system, causing serious damage and
possible flue gas spillage or water leak-
age into the surrounding area.
• Please read the information listed on the
right. If contaminating chemicals are locat-
ed near the area of the combustion air in-
let, 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
• If the combustion air is taken from the
room, an air grille must be installed to
provide air for combustion. The air grilles
should be sized in accordance with ANSI
Z223.1/ NFPA54 and/or Natural Gas and
Propane Installation Code CAN/CSA
B149.1.
• The grilles providing air supply taken from
within the property should be clearly la-
beled “AIR SUPPLY, DO NOT COVER OR RE-
STRICT. FAILURE TO PROVIDE ADEQUATE
AIR FOR COMBUSTION COULD RESULT IN
SERIOUS INJURY, OR DEATH.”
