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. See Section 3-1 for converting the unit
