CHAPTER 2 - COMBUSTION AIR & VENTING
2.1. Combustion Air Contamination
If the INSTINCT combustion air inlet is located in an
area likely to cause or contain contamination, or if
products which could contaminate the air cannot
be removed, the combustion air must be repiped
and terminated at another location. Contaminated
combustion air will damage the unit and its burner
system, and can result in substantial property
damage, serious injury, or death.
• Do not operate the INSTINCT if the
combustion air inlet is located near a
laundry room or pool facility. These
areas will always 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
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, as
indicated in Chapter 6 on Page 35.
• Failure to comply with these instructions
will result in substantial property damage,
serious injury, or death.
• The INSTINCT boiler is classified as a Cate-
gory IV appliance. This utilizes uncontami-
nated indoor or outdoor air for applicance
combustion. A direct vent installation uses
the outdoor air. Air supply, combusiton
chamber, heat exchanger 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.
WARNING
DANGER
• An in-direct installation uses uncontaminat-
ed indoor air for appliance combustion.
• When the air for combustion is taken from
the room air grilles must be installed by
the contractor. 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 grille providing air when taking air
directly from the room should be clearly
labelled; "AIR SUPPLY, DO NOT COVER OR
RESTRICT. FAILURE TO PROVIDE ADEQUATE
AIR FOR COMBUSTION COULD RESULT IN
SERIOUS INJURY, OR DEATH."
