Figure 4. Installing the supplied metal headers, both sides typical.

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 same size 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

Figure 4.c Securing the Nailing Flange Extension.

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

bottom of nailing ange to a 90° angle. NOTE: Do not install nailing

ange when installing a Montigo Surround.

Under no circumstances can Montigo ex venting be cut to

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:

• Venting can originate from the unit through the top or 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).

• Termination location must be a minimum 6’ from a mechanical air inlet.

• 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.

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 over terminations 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.

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.
