Section 3-3-2: Venting Components
The following components and associated Montigo part numbers are for
installation of a roof or wall mounted termination. Use of non-Montigo
approved parts will VOID the warranty and may impede operation of
the fireplace.
Connection and installation of the vent
components should adhere to the following
guidelines:
• Use any combination of rigid and flex pipe as required and in any
orientation (Male connectors can face in any direction).
• 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 horizontal 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.
• Rigid pipe may be cut less than half way from the FEMALE END ONLY.
• Ensure when cutting sections of rigid pipe to maintain integrity of
internal supports.
• Flex pipe cannot be cut
• Place the springs, supplied with the pipe kit (flex only), 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 first section of
venting connected directly to the fireplace, offering greater flexibility
of installation and absorption of movement.
• Firestops must be installed as required by national & local codes.
• 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.
IMPORTANT:
Please refer to your Building Envelope Engineer
or Waterproofing Consultant for a review of ALL
penetrations through exterior walls or the roof.
