Connection and installation of the vent components should
adhere to the following guidelines:
 Montigo recommends the use of a ex section for the nal pipe
connected directly to the replace offering greater exibility
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 Waterproong
Consultant for further recommendations�
 Use any combination of rigid and ex 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 ue.
 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 Waterproong Consultant
for a review of ALL penetrations through
exterior walls or the roof�
