Section 3: Venting
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.
