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.
