IMPORTANT
Cementboard: The included
cement board facing is
sized to overlap the 2x4 and
platform noted in the framing
section. The board will not t
if the unit is placed directly on
the oor.
IMPORTANT
Cementboard: The outside
edge of the cement board
facing must be in the center
of a structural stud.
It is highly recommended to apply high temp resistant RTV Silicone
where cement board touches replace body. At least 48h cure time
before applying nishing or ring replace
NOTICE
Supplied cement board can be drilled to add extra fasteners or support if
nishing application calls for it. No extra fasteners shall be used to attach
cement board to replace body
NOTICE
Supplied cement board is for minimum installation requirements for non-
combustible surfaces. When installing heavy nishing materials such as
Natural Stone, Granite, Marble, Etc., Full sheets (4’x8’) of cement board is
recommended to minimize number of joints and to reduce risk of cracking
(supplied cement board can be used as stencil to predrill new cement sheets)
Any replacement sheet of cement board must be calcium silicate based as to
withstand continuous high operating temperatures.

Installation
Chaseventing
At a minimum, a 120 square inch opening is required in the nished
enclosure to keep temperatures within a safe level. This can be achieved
in a variety of ways such as the few shown below.
The opening of the chase cannot be lower than 3" from the top of the
enclosure to prevent heat from pocketing at the top of the enclosure.
A minimum of 2" from the top of a chase vent to the ceiling is needed.
Any combination of the above examples is an acceptable chase vent
providing they add up to at least 120 square inches.
NOTE: Chase venting not required if using Cool Wall Advantage heat
diversion system.

The recess must be made from Non-Combustable materials. Recess can
be increased beyond a 4" depth by using a 45° or 90° elbow in venting
after the minimum 3' upward distance is achieved, 1" clearance from
venting to combustibles must still be maintained.

Under no circumstances
can Montigo ex venting
be cut to accommodate
an installation. Use an
alternative length to
complete your vent run.
NOTICE
Connectionandinstallationofthevent
components should adhere to the following
guidelines:
• 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 (for rigid lengths).
• Connect all vent sections using a minimum of three sheet metal
screws on the inner AND outer pipe (for ex lengths).
• 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.
Section 3: Venting
The 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 should it be impossible to
meet the venting guidelines laid out below please contact your Montigo
dealer to discuss power venting options.
Notes For Planning Venting:
Included Restrictor plates:
1" Bae
1.5" Bae
1.75" Bae
For horizontally terminated
ventruns:
Shorter runs, or multi elbow
installations would use the
included 1.5'' or 1'' restrictor.
For vertically terminated
ventruns:
Vertical runs require ordering
the PVVR8 or PVVR15 restrictor.
Lengthy vertical runs will
require the PVVR25 vertical
vent restrictor (all installed at
the termination).
The distinction is supplied with 3 dierent sized restrictor plates to
improve ame eciency. The size of restrictor used largely depends
on the number of elbows used in the vent run, as well as vertical rise.
• Venting originates from the top of the unit.
• Venting can terminate through the roof or exterior wall.
• For a detailed diagram of allowed termination locations, see
Appendix A.
• Once the termination location has been established refer to the
appropriate section for installation details.
• For Heat Shield requirements see Section 3-3-3.

XG022214
Installation
Section 3-3-2: Venting Components
The following components andassociated Montigo part numbers are 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. Reducing to 4/7 requires a reducer that is not supplied with the
replace, please reference the below table to determine what
reducer is required.

Forverticallyterminatedventruns:
Vertical runs require ordering the PVVR8 or PVVR15 restrictor. Lengthy
vertical runs will require the PVVR25 vertical vent restrictor (all installed
at the termination). When using these restrictors, the included rebox
restrictor size can be reduced or removed entirely.

Section 3-2-1: Roof Venting termination
• 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).
• See Appendix A for termination locations.
• A maximum of two osets (each oset is made up of 2-90° bends)
may be made for vertical vent runs.

nation with no oset in vent run.

Installationofaterminationshieldforvinylsiding
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. Fasten the termination to the MSR Frame using a minimum of 4 screws.
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. Fasten the termination to the BSR Frame using a minimum of 4 screws.

Installing heat guards
Installing heat guards overterminations is recommended in installations
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.

Installing a Wall Mounted Heat shield
The RHS10* Heat shield must be used if vent pipe passes through a
wall or ceiling within 6' of the unit.
To install the Heat shield, Slide the Inner Section over the vent pipe that
will connect to the replace. Then fasten the vent pipe to the back of
the replace with a minimum of three sheet metal screws. From the
outside slide the outer section on. To complete the installation fasten
the Heat Shield Outer Section & inner section to the structure.
