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.
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.
IMPORTanT:
Please Refer to your Building Envelope Engineer
or waterproofing Consultant for a review of aLL
penetrations through exterior walls or the roof.
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.
