CHAPTER 4 - INSTALLATION REQUIREMENTS
Pipe hangers must not be tightly clamped to pipe
to allow for thermal expansion/contraction move-
ment. Pipe clamps or hangers should not contain
any sharp edges which can damage the pipe.
8. The vent and combustion air piping must be sloped
continuously from the termination back to the boiler
with at least 1/4” drop per foot [6 mm/30 cm] of run.
Do not allow any sags in the run of piping.
Do not slope the vent or combustion air pip-
ing downward away from the boiler. Conden-
sate could freeze and block the vent pipe or
damage the exterior of the building or sur-
rounding landscape, resulting in substantial
property damage, serious injury, or death.
9. Maintain a minimum clearance of 1/4” [6 mm]
between the vent pipe and all combustible or
non-combustible materials for 3” PVC/CPVC vents or
1” [2.5 cm] for 2” PVC/CPVC vents. The installer must
seal any wall, oor or ceiling penetrations as per local
code requirements.
It is recommended that the installer uses the
same number of elbows and length of pipes on
the venting and the combustion air inlet sys-
tems.
Covering PVC/CPVC vent pipe and fittings with
thermal insulation is prohibited.
4.3.2 Stainless Steel Vent Systems
• When using Stainless Steel Vent, refer to vent
manufacturer’s installation instructions supplied

4.4. Carbon Monoxide Detector Installation
Triangle Tube requires the installation of a minimum
of two (2) hard wired carbon monoxide detectors with
an alarm and battery back-up in the mechanical room
where the INSTINCT is located and another installed in
the living area outside the bedroom(s) for all installa-
tions.
Each carbon monoxide detector shall comply with
NFPA 720 and be ANSI/UL 2034 listed and IAS certied.
Consult the local authority having jurisdiction for any
additional carbon monoxide detector requirements in
your area. See page 29 for additional carbon monox-
ide detector requirements in Massachusetts.
A byproduct of any gas fired appliance is
carbon monoxide. Failure to install carbon
monoxide detectors with alarms can result in
serious injury, or death.
