Notes For Planning Venting
• RP-Series fireplaces are Power Vent Designated and use Montigo's
5/8 vent pipes.
• Venting originates from the top or rear of the unit.
• Venting can terminate through the roof or exterior wall.
• Once the termination location has been established refer to the
appropriate section for installation details.
• All fireplaces are shipped Top Vent from the factory.
• Follow the chart on page 20 for maximum vent run and maximum
elbows.
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 1½" of
overlap.
• Connect all vent sections using a minimum of three sheet metal
screws on the outer pipe flue.
• 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.
• 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.
• When passing vent pipe through a wall use a heat shield.
• 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.
