CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS
1.1. Ventilation and Combustion Air Re-
quirements
The INSTINCT boiler is classied as a Category IV appli-
ance. This utilizes uncontaminated indoor or outdoor air
for appliance combustion.
A direct vent installation uses the outdoor air. Air supply,
combustion 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 indirect installation uses uncontaminated indoor air
for appliance combustion.
In the case of Indirect vent installation, the
space must be provided with ventilation /
combustion air openings properly sized for
all make-up air requirements (exhaust fans,
clothes dryers, fireplaces, etc.) and the to-
tal input of all appliances, including the IN-
STINCT when located in the same space. Fail-
ure to provide or properly size the openings
can result in substantial property damage,
serious injury, or death.
For installations in which the INSTINCT shares the space
with air movers (exhaust fan, clothes dryers, replaces,
etc.) and other combustion equipment (gas or oil) the
space must be provided with adequate air openings to
provide ventilation and combustion air to the equip-
ment. To properly size the ventilation / combustion air
openings, the installer must comply with the National
Fuel Gas Code (NFPA 54 / ANSI Z223.1) for installations
in the U.S. or CAN/CSA B149.1 for installations in Can-
ada.
WARNING
• 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 di-
rectly from the room should be identified
to the consumer and the importance of
ensuring that the grilles are not restricted
or blocked in any way clearly explained to
the consumer. The grilles should be clear-
ly labeled “AIR SUPPLY, DO NOT COVER
OR RESTRICT. FAILURE TO PROVIDE ADE-
QUATE AIR FOR COMBUSTION COULD RE-
SULT IN SERIOUS INJURY, OR DEATH.”
A byproduct of any gas red appliance is carbon mon-
oxide (CO), which can be a health hazard when its con-
centration in the ambient air is too high.
• Triangle Tube requires the installation of
a minimum of two (2) hard-wired carbon
monoxide (CO) detectors with an alarm
and battery back-up; one in the mechanical
room where the boiler is located and
another installed in the living area outside
the bedroom(s) for all installations. Consult
the local authority having jurisdiction for
any additional carbon monoxide detector
requirements in your area. See Chapter 2
of the INSTINCT Installation & Maintenance
Manual for additional carbon monoxide
detector requirements in Massachusetts.
• Failure to comply with these instructions
will result in substantial property damage,
serious injury, or death
