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")�
„
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�
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�
IMPORTANT:
Please Refer to your Building Envelope
Engineer or Waterproofing Consultant
for a review of ALL penetrations through
exterior walls or the roof�
