Clearances
When installing a shelf over the top of the replaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 2" from the rear
of the replace to a wall, or any combustible materials. A clearance to
combustibles of 9" for H34DF* and a clearance to combustibles of 11"
forHC34DF* , & HL34DF*is required to theundersideof any combustible
shelf materials, Figure 3.
For Top Vent applications, the minimum clearance is 2" from the rear of
the replace to a wall, or any combustible materials, and 17 1/2" to the
underside of any combustible shelf materials, Figure 4.
For Top or Rear Vent applications where the Minimum mantel height
is required above the replace, (for an alcove or low prole shelf), ALL
Materials MUST BE NON-COMBUSTIBLE, Figure 5. The minimum
clearance is 2" from the rear of the replace to a wall, or any combustible
materials. 1” clearance is maintained on sides and bottom of vent runs
and 2” above horizontal vent runs to any combustible material.

Installing The Standoffs
To avoid elevated mantel temperatures, all H*34DF*-Series gas
replaces are required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the standoff
maintains a 6" clearance.
Figure 6. Installing the standoff's.
Installing the Nailing Flange Extension - HC34DF* Only
Once the replace is placed into the rough framed opening, the supplied
nailing ange extension (Part No. HC34074) must be fasten securely
into place, with nails or wood screws. as shown in Figure 7.

Front View Side View
Figure 7. Installing the Nailing Flange Extension, see , Figure 25a.
The supplied nailing ange extension must be placed along the top
edge of the replace and securely fastened in place to the combustible
wood framing.
Note: The nailing ange extension can be substituted with a piece of
NON-Combustiblematerial of the same size and thermalcharacteristics,
ie: cement board or equivalent. This is recommended in applications
where the facing materials will not adhere to the metal nailing ange.

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 originatesfromtheunit through the top orthrough therear
Ventingcanterminate through theroof orthrough anexterior wall.
For a detailed diagram of allowed termination locations, see
Appendix A.
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.

Termination (MVTK-1)
Thissectionappliestoinstallationswherethe direct vent termination
will be roof mounted.
Section 3-2-1: Venting Layout: Roof Mounted Termination
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 affected).
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 11 to 11c).
Termination location must be a minimum 6’ from a mechanical
air inlet.
For a more detailed diagram of allowed termination locations,
see Appendix A.
A maximum of two offsets (each offset 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.

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
ofthe termination. (Seeinset).This willprovidemore 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.

WARNING:
An inspection of the explosion relief appers and door
MUST be made prior to lighting the replace. Faulty seal
on the door gasket and/or explosion ports will result in
products of combustion leaking into the living space and
may result in carbon monoxide poisoning.
Selectionofcomponentsanddetails of venting layout should adhere
to the following guidelines:
Vent terminations must not be recessed in walls or siding.
For Heat Shield requirements, see Section 3-3-3 on page 16.
Once the proposed venting layout has been determined refer to Figure
14, 15, or 16 to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT
All measurements for vertical or horizontal runs are measured
from centre of the vent pipe.
Venting runs must fall within the limits set by the venting graph,
see Figure 14 or 15.
The 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 Graph Figure 14 or
15 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:
Montigo recommends the use of a ex section for the nal pipe
connected directly to the replace offering greater exibility of
installation and absorption of movement.
Firestops must be installed as required by National & local codes.
Montigorecommendsthat all exterior cornersand jointsbe sealed
with exterior caulking. However, we encourage you to consult
your Building Envelope Engineer or Waterproong Consultant
for further recommendations.
Section 3-3-2: Venting Components
The following components and associated Montigo part numbers for
installation of a roof or wall mounted termination. Use only Montigo
Vent Components. Use of non-Montigo 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.
Rigidpipemay be cut less thanhalf wayfrom thefemale end only.
Ensure when cutting sections of rigid pipe to maintain integrity
of internal supports.
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.
IMPORTANT:
Please Refer to your Building Envelope Engineer
or Waterproong Consultant for a review of ALL
penetrations through exterior walls or the roof.

Installing the remote On/Off Wall Switch
The H*34DF* gas valve may be connected to a wall switch. Do NOT
connect any external power to the remote switch. The valve will
generate its own power on a millivolt circuit or will draw its power from
an AC Connection inside the replace, depending on the model of the
unit. Use only low voltage wire, and DO NOT connect any external
power to the remote switch.
Refer to Figure 20, 21, or 22 for wiring requirements.
NOTE: The switch location must not exceed 30' from the replace.
NOTE: If any of the original wire supplied with the appliance
is replaced, it must be replaced with the same type,
or its equivalent.
