Montigo supplies a variety of direct venting and termination options.
The direct vent termination location MUST be selected such that it is the
highest point in the venting assembly. It should also be selected such
that it provides the shortest vent run possible. Should it be impossible
to ensure that the termination is the highest point or to meet the
venting guidelines laid out below please contact your Montigo dealer
to discuss power venting options.
Notes For Planning Venting:
• Venting can originate from the unit through the top or through the rear
• Venting can terminate through the roof or through an exterior wall.
• Refer to Appendix A - Termination Locations to ensure the planned
termination location is acceptable.
• Once the termination location has been established, refer to the
appropriate section below for installation details
• All fireplaces shipped from the factory are top vent.
• Silicone application is NOT required when joining Montigo vent
pipes and components.
Section 3-1: Converting top/rear vent
Use the following instructions to convert a unit for rear vent use:
• Remove the rear flue cover and gasket on the flue outlet.
• Next, Remove the Top flue collar's on the flue outlet.

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").
• 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 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.
• Flex pipe cannot be cut
• Place the springs, supplied with the pipe kit (flex only), 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 first section of
venting 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.
