Section 3-2-2: VENTING COMPONENTS
Select from the following components and associated Montigo
part numbers for installation of a Roof Mounted Termination.
Use only Montigo Vent Components. Use of non-Montigo parts
will void the warranty and may impede operation of the replace.
 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 ue.
 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 ex section for the nal pipe
connected directly to the replace offering greater exibility of
installation and absorption of movement.
 When penetrating a combustible ceiling, a ceiling restop must
be used.
