Figure 4. Non combustible header H42ST060 x 2 pcs.
Included with the L42DF-ST Gas replace, is a framing heat shield Kit.
This kit is fabricated from galvanized steel and arrives with six (6) pieces,
as shown below. The shields protect all adjacent combustible materials,
mantels and mouldings from excessive heat radiated by the replace.
STEP 1. Fasten 4 side shields in place with nails or screws, ush with
the framing as shown. These are installed with the Wide anges facing
the center of the replace opening, and the shallow ange toward
inside of room.
Included with the L38DF-ST* gas replace are two metal headers
made of galvanized steel. The metal headers must be installed after
the replace has been back framed in place. Install metal headers at
34 1/2" from the base of the unit, as shown in gure 6.
STEP 2. Nail or screw the top shield in place ush with framing
NOTE: The nailing ange extension can be substituted with a piece of
NON-Combustible material of the samesize and thermal characteristics,
ie: cement board or equivalent. This is recommended in applications
where the facing materials will not adhere to the metal nailing ange.
Installing the Nailing Flange Extension

Before installing the supplied nailing ange extension, fold tabs at

NOTICE
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 fromtheunit through the topor through the side.
• 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:
1. Remove the Side ue cover and gasket (5" and 8") on the ue
outlet, as shown in Figure 9.
2. Next, Remove the Top ue collar's (5" and 8") on the ue outlet,
as shown in Figure 9.
3. Install the (removed) Side ue cover and gasket material, to the
Top vent outlet. Fasten the cover with included hardware, as
illustrated Figure 9a.
4. Install the (5" and 8") collars to the Side vent outlet using the
included hardware, as illustrated Figure 9a.

Roof mounted Terminations
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 6 to 6c).
• Terminationlocation must bea minimum 6’ froma mechanical airinlet.
• 1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
• 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.

Installationofterminationwithbuiltinframe
A Termination with a Built-In Frame is installed during framing of a
structure.
1. Frame the termination opening to 11" x 11".
2. Install exterior sheathing to the structure framing.
3. Fasten the termination to the sheathing using a minimum of 4 screws.

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. Fastenthe termination to the MSRFrame using a minimum of4screws.
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 to the BSR Frame using a minimum of 4 screws.

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.

Top Venting Layout: Wall mounted
termination. L52ST:
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 Graph Figure
8 or 8b with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.

Installation

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 150% 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 ½” 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.
• Ensure when cutting sections of rigid pipe to maintain integrity of
internal supports.
• FLEX PIPE CANNOT BE CUT
• Place the springs, supplied with the pipe kit (ex only), 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 rst section of
venting 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.
• Montigo recommends that all exterior corners and joints be sealed
with exterior caulking. However, we encourage you to consult your
Building Envelope Engineer or Waterproong Consultant for further
recommendations.
IMPORTANT:
Please Refer to your Building Envelope Engineer
or Waterproong Consultant for a review of ALL
penetrations through exterior walls or the roof.

your vent run.
