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
