NOTE: When constructing the framed opening, please ensure there is
access to install the gas line when the unit is installed. See Figure 26.
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, and 9" clearance
from the top of the replace to the underside of any combustible shelf
materials.
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.

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.

Figure 11 H34DLL* Top Vent Venting Graph for wall mounted terminations,
See Figures 14, 14a, or 14b.
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 11,
12, or 13 with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 114" and the horizontal run to
the wall ange of the vent termination is 144", this would be an accept-
able installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 42" and the horizontal run to
the wall ange of the vent termination is 90", this would NOT be an
acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 66" and the hori-
zontal run to the wall ange of the vent termination is 150", this would
NOT be an acceptable installation.
Section 3-3-1: VENTING LAYOUT: Wall mounted termination.
Selection of components and details of venting layout should
adhere to the following guidelines:
Vent terminations must not be recessed in walls or siding.

Installation
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.
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.
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 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.
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.

Note: After gas line is connected, each appliance connection,
valve and valve train must be checked while under normal
operating pressure with either a liquid solution, or leak
detection device, to locate any source of leak. Tighten any
areas where bubbling appears or leak is detected until
bubbling stops completely or leak is no longer detected.
DO NOT use a ame of any kind to test for leaks.
WARNING!
When pressure testing the replace, Gas line, and input system
follow the appropriate local codes or your area. DO NOT connect
the replace to pressures in excess of 1/2lb. This will damage the
gas control valve.
The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
To check pressures, control valves have a provision to remove
a 1/8” N.PT. plug to be tted with a hose barb.
Montigo requires a service shut off valve be located in an
accessible location to isolate the gas supply.
Only install gas shut-off valves approved for use by the state,
province, or other governing body in which the replace is being
installed.
Section 5-3: GAS CONNECTION
See Figure 26 for location of gas line access.
Flexible gas connectors must not exceed 3 feet in length, unless
allowable within local regulations.
Connect incoming gas line to the 1/2"or 3/8" gas inlet port.
Purge all air out of gas line.
Check appliance connection, valve and valve train under normal
operating pressure with a commercially available leak check
solution.
DO NOT USE A FLAME OF ANY KIND TO TEST FOR LEAKS.
