Section 4-2-2: Venting Components
The following venting components and associated Montigo part
numbers are available for horizontal installations:
Connection and installation of the vent components should
adheretothefollowingguidelines:
■ 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 all sides 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.
■ All exterior joints in venting should be sealed with high heat
silicone RV230.
