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 termina-
tion 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 originates 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 for installation details.
All fireplaces shipped from the factory are Top vent.
