Section 3: Venting
Montigo offers 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 originates from the top or rear of the unit
• 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.
• Silicone application is NOT required when joining Montigo vent
pipes and components.
NOTICE
Under no circumstances can Montigo flex venting be cut to
accommodate an installation. Use an alternative length to complete
your vent run. (Excluding flex included in the PVK05, MVK05)
PVK05 (5/8), PVK05F (5/8), MVK05 (4/7), MVK05F (4/7)
PVK05 / MVK05 Flex Vent Kit is a standalone 5 ft. vent kit that cannot be combined
with Montigo Flex or Montigo Rigid pipe to extend beyond the 5ft of flex included
in this kit. The Flex in this kit can be cut down if shortening is required. Any other
venting configuration beyond the 5ft included in the kit will require going to either
Montigo Rigid pipe or Montigo Flex pipe referenced in the manual pages Venting
section.
PVK05 Includes RHS101 heat shield, 5' flex pipe (with spacers), and PTO4 termination
PVK05F (WITH TERM. FRAME) Includes RHS101 heat shield, 5' flex pipe (with
spacers), and PTO4F termination
MVK05 Includes RHS101 heat shield, 5' flex pipe (with spacers), and MTO4 termination
MVK05F (WITH TERM. FRAME) Includes RHS100 heat shield, 5' flex pipe (with

Restrictor plate
The fireplace is equipped with a factory installed restrictor set at fully
open. If fireplace vent is terminated horizontally, NEVER CLOSE the
restrictor completely. Adjust the restrictor opening by judging flame
characteristics after 20 minutes of burn time (on cold start, for first
few minutes the flames might be blue).
If flames ghost off the burners or if sooting occurs (mostly with propane)
open the restrictor fully and work backwards in increments to determine
the correct position.
FOR REAR VENT RESTRICTOR MUST BE LEFT FULL OPEN.
FOR POWER VENTED UNITS RESTRICTOR MUST BE CLOSED.
For most runs that include lengths of both horizontal and vertical pipe,
especially ones with multiple elbows or long horizontal runs, restrictor
should be full open.
Restrictor opening should be adjusted for long vertical lengths with
short horizontal runs or vertical only runs to reduce flue draft.
Recommended settings for vertical runs (depends on installation
specifics, altitude, fuel and other factors):
• For Verticals 3' to 6' – various between fully open to 1" open
• For Verticals 7' to 10' – 1" open or fully closed
• For Verticals over 10' –fully closed
