Section 3-3-2: VENTING COMPONENTS

The following components and associated Montigo part numbers are
available for installation of a Wall Mounted Termination. Use only Montigo
Vent Components. Use of non-Montigo parts will void the warranty and
may impede operation of the fireplace.
A - Termination
B - Frame Kits
C - Flex Sections
D - Rigid Sections
E - Elbows
Connection and installation of the vent components should adhere
to the following guidelines:
■ Use any combination of rigid and Flex pipe as required.
■ Flex sections may be stretched up to 50% of their total length
(e.g. a 24" section maybe stretched to 36").
■ Connect all vent sections using a minimum of three sheet metal
screws on the outer pipe flue..
■ Ensure the pipe ends male to female slide in a minimum of 1
1/2" of overlap.
■ Ensure all runs are supported with a minimum of 3 supports per
10' of venting.
■ When hanging/ supporting venting, ensure that 1" clearance
is maintained on sides and bottom of vent runs and 2" above
horizontal vent runs to any combustible material.
■ Ensure when cutting sections of rigid pipe to maintain integrity
of internal supports.
■ Place the springs, supplied with the pipe kit, between the outer
and inner pipes to keep the pipes separate and avoid any possible
hot spots.

■ Montigo recommends the use of a flex section for the final pipe
connected directly to the fireplace offering greater flexibility of
installation and absorption of movement.
■ When penetrating a combustible ceiling, a ceiling firestop must
be used.
■ Montigo recommends that all exterior corners and joints be
sealed with exterior caulking however we encourage you to
consult your Building Envelope Engineer or Waterproofing
Consultant for further recommendations.
