Installation
■ 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.
Connection and installation of the vent components should adhere
to the following guidelines:
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.
■ 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.
