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:
• Ventingcan originate fromthe unitthrough thetop orthrough 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 replaces shipped from the factory are top vent.
• Silicone application is NOT required when joining Montigo vent
pipes and components.
Section3-1:ConvertingtoSideVent
Use the following instructions to convert a unit for side vent use:
• Remove the Side ue cover and gasket (5" and 8") on the ue outlet,
as shown in Figure 5.
• Next, Remove the Top ue collar's (5" and 8") on the ue outlet, as
shown in Figure 5.
• Install the (removed) Side ue cover and gasket material, to the Top
vent outlet. Fasten the cover with included hardware, as illustrated

The following details are some possible congurations for roof mounted
terminations. See below.
This section applies to installations where the direct vent termination
will be roof mounted.
Section3-2-1:VentingLayout
Selection of components and details of venting lay out should adhere
to the following guidelines:
• The maximum termination point is 32’ above the replace (NOTE:
if the maximum termination height is used, the ame pattern may
be aected).
• The Vertical termination must be a minimum 2’ higher than where
the termination exits the roong materials, (asphalt shingles, cedar
shakes, etc). This distance should be measured from the high side of
the roof slope where the ue ashing intersects the roong materials.
(see Figures 8 to 8c).
• Terminationlocation mustbe aminimum 6’from amechanical airinlet.
• Termination location must be a minimum 18” from a parapet wall.
• For a more detailed diagram of allowed termination locations, see
Appendix A.
• A maximum of two osets (each oset is made up of 2-90° bends)
may be made for vertical vent runs.
• Firestops must be installed as required by National & local codes.
• Ensure all horizontal runs are supported with a minimum of 3
supports per 10’ of venting.
• Install all roof ashing and storm collars as shown.

The VSS Termination shield is installed when the exterior of a structure
is clad with Vinyl siding. It is placed directly above, and on-center with
the termination.
Installation of termination frame at time of framing
Terminations with a MSR frame allow the installation of the frame prior
to installation of the termination.
1. Frame the termination opening to 12" x 12".
2. Secure the MSR Frame to the exterior sheathing of the structure.
3. Fastenthe terminationto the MSRFrame usinga minimumof 4screws.
1. Frame the MOSR opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs, concrete,
or nished wall construction using a minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, (from
the inside) and attach to the MOSR by installing a min. quantity of 4
bolts into the threaded nuts on the MOSR Frame.
Installation of termination frame at time of framing in masonry
Terminations with a BSR frame allow the installation of the frame in
masonry prior to the installation of the termination
1. Frame the BSR opening to 12" x 12".
2. Secure the BSR Frame to the exterior sheathing of the structure.
3. Fastenthe termination tothe BSR Frameusing aminimum of 4screws.

Installing heat guards
Installing heat guards overterminations is recommended ininstallations
where the termination is located within 7' feet above grade, or above
a pedestrian walkway, and may be required by code in public areas.
1. Ensure that the two long mounting brackets are facing the bottom
of the termination (See inset). This will provide more heat protection
at the top of the termination, where temperatures are highest.
2. Attach to the faceplate of the termination using four sheet metal
screws.

center of the vent pipe.
• Venting runs must fall within the limits set by the venting graph.
ExampleA:(AcceptableInstallation)
If the vertical dimension from the hearth is 120" and the horizontal
run to the wall ange of the vent termination is 138", this would be an
acceptable installation.
ExampleB:(UnacceptableInstallation)
If the vertical dimension from the hearth is 48" and the horizontal run
to the wall ange of the vent termination is 96", this would not be an
acceptable installation.
ExampleC:(UnacceptableInstallation)
If the vertical dimension from the oor of the replace is 72" and the
horizontal run to the wall ange of the vent termination is 120", this
would not be an acceptable installation.
Side Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the replace ue collar to
the wall ange of the termination. Plot on the Venting Grap with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.

Connectionandinstallationofthevent
components should adhere to the following
guidelines:
Section3-3-2:VentingComponents
The following components and associated Montigo part numbers for
installation of a roof or wall mounted termination. Use of non-Montigo
approved parts will VOID the warranty and may impede operation of
the replace. • Use any combination of rigid and ex pipe as required and in any
orientation (Male connectors can face in any direction).
• Flex sections may be stretched up to 50% of their total length (e.g.
a 24” section maybe stretched to 36”).
• Connect all vent sections using a minimum of three sheet metal
screws on the outer pipe ue.
• Ensure the pipe ends male to female slide in a minimum of 1 1/2”
of overlap.
• Ensure all horizontal runs are supported with a minimum of 3
supports per 10’ of venting.
• When hanging/supporting venting, ensure that 1” clearance is
maintained on sides and bottom of vent runs and 2” above horizontal
vent runs to any combustible material.
• Rigid pipe may be cut less than half way from the FEMALEENDONLY.
• Flex pipe cannot be cut
• Ensure when cutting sections of rigid pipe to maintain integrity of
internal supports.
• For ex venting, place the springs supplied with the pipe kit, between
the outer and inner pipes to keep the pipes separate and avoid any
possible hot spots.
• Montigo recommends the use of a ex section for the nal pipe
connected directly to the replace oering greater exibility of
installation and absorption of movement.
• Firestops must be installed as required by National & local codes.
IMPORTANT:
Please Refer to your Building Envelope Engineer
or Waterproong Consultant for a review of ALL
penetrations through exterior walls or the roof.

Flexmasterasalternateventing
Flexmaster ex venting is approved on all Montigo residential replaces.
Flexmaster Flex pipe may be used in any length as long as the respective
vent graph provided in the manual is adhered to. This approval on
Flexmaster Flex includes all and any prepackaged vent kits by Montigo
containing Flexmaster venting. All Montigo prepackaged vent kits may
be used on any Montigo residential unit replace. When using a Power
vent you must use Montigo pipe only.
HORIZONTAL FLEX RUN REQUIREMENTS:
Follow venting graph for each model as required. Support horizontal
sections every 2ft to prevent sagging, allow for a ¼" rise per foot of
horizontal. Use high temperature silicone and three (3) screws at
replace collar and termination collars. Reduce horizontal run by 36"
for each 90° oset after the rst one.
Support straps OR
Support ring and plates
Support straping
Must convert from ex to
rigid before termination
Support ring and plates
Support horizontal
section every 2' with
plumbers strapping
Flex sections can be
connected with a
coupler providing 3
screws are used on
each side and the
seam is sealed with
high temperature
silicone
Allow for a ¼" rise per
foot of horizontal
Maintain 2" clearance
from horizontal venting to
combustibles
Ensure spacers are
located at elbows
to avoid the inner
pipe touching the
outer and creating
a hot spot
Firestop
VERTICAL THROUGH THE ROOF:
Follow venting graph for each model as required. Use mil pack and
three (3) screws at joints, support horizontal section every 2 ft, use one
half of RHS100 as a restop when passing through oors and ceilings,
use additional restops as necessary to keep construction debris and
insulation away from contact with vent.
