CHAPTER 2 - COMBUSTION AIR & VENTING
2.1.

Combustion Air Contamination

WARNING
If the EXALT 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.
DANGER
• Do not operate the EXALT 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 39.
• Failure to comply with these instructions
will result in substantial property damage,
serious injury, or death.
• The EXALT boiler is classified as a Category
IV appliance. This utilizes uncontaminated
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.
• An in-direct installation uses uncontaminated
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."
