Connection and installation of the vent components should
adhere to the following guidelines:
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.
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.
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”).
Ensure the pipe ends male to female slide in a minimum of
1 1/2” of overlap.
Connect all vent sections using a minimum of three sheet
metal screws on the outer pipe flue.
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.
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.
IMPORTANT:
Please Refer to your Building Envelope
Engineer or Waterproofing Consultant
for a review of ALL penetrations through
exterior walls or the roof.
