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.
32' max
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.
