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 roong 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
roong materials. (see Figures 11 to 11c *).
Termination location must be a minimum 6’ from a mechanical
air inlet.
Termination location must be a minimum 18” from a parapet wall.
A maximum of two offsets (each offset is made up of 2-90°
bends) may be made.
Install a restop at any location where venting passes through
combustible materials and construction.
Utilize support straps, or support plates, and rings (as required)
to meet acceptable building practices.
Install all roof ashing and storm collars as shown.
. Top vent, Roof mounted termination with no offset in vent run.

Connection and installation of the vent components should
adhere to the following guidelines:
Use any combination of rigid and Flex pipe as required.
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.
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.
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.
When penetrating a combustible ceiling, a ceiling restop must
be used.
Montigo recommends that all exterior corners and joints be sealed
with exterior caulking however we encourage you to consult
your Building Envelope Engineer or Waterproong Consultant
for further recommendations.

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 longmounting 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.

adhere to the following guidelines:
The following components and associated Montigo part numbers are
available for installation of a 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 Flex pipe as required.
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.
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.
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.
When penetrating a combustible ceiling, a ceiling restop must be used.
Montigo recommends that all exterior corners and joints be sealed
with exterior caulking however we encourage you to consult your
Building Envelope Engineer or Waterproong Consultant for further
recommendations.

After gas line is connected, 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.

The manifold outlet pressure is set from the factory to the
appropriate pressure but should be veried.
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.
See Figure 22 below 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.
Section 5-1: FUEL CONVERSION
Verify that your replace is compatible with your available gas
type. (Natural Gas or Propane shown by "N" or "L" in your
model number
If gas type is not compatible, contact your local Montigo
representative to purchase a conversion kit.
Conversion kits must be installed by a qualied service technician.
Section 5-2: GAS PRESSURE
Optimum appliance performance requires proper input pressures.
Gas line sizing requirements will be determined in ANSI Z221.3
National Fuel Gas Code in the USA and CAN/CGA B149 in
Canada.
Pressure requirements are:
XW2034
We recommend careful consideration
be given to the effects of elevated
mantel temperatures which may be in
excess of product design, for example:
candles, plastic or pictures. This can
cause melting, deformation, discolor-
ation or premature failure of T.V. radio,
and other electronic components.
CAUTION
When pressure testing the fireplace,
Gas line, and input system follow the
appropriate local codes or your area.
DO NOT connect the fireplace to
pressures in excess of 1/2lb. This will
damage the gas control valve.

Installation
Combustible mantels and facings.
Combustible mantels and mouldings may be safely installed over the
top and on the front of the replace provided that they do not project
beyond shaded area shown in Figure 24.
Fireplace Facing
When sizing the nish material for your replace, it is important to
remember the following:
The face of the replace may be painted to match the room decor,
provided you use a heat-resistant paint. Decorative facing must not
extend past the replace opening at all, because it will interfere with
the access to retainers for removal of glass door.
Mantels & Surrounds
National Canadian Gas Association mantel test requirements
are for re hazard prevention to combustible materials.
New technology, to meet consumer and government demands for the
wise use of energy, has prompted us to manufacture many models of
replaces which are hot, fuel and energy efcient.
Please be aware; temperatures over the mantel will rise above normal
room temperature and walls above replace may be hot to touch.
When covering the upper metal portion of the replace with a non-
combustible material Please Note: The decorative facing materials
may be subject to temperatures in excess of 250° F. This should be
considered when selecting facing materials.
We recommend careful consideration be given to the effects of elevated
mantel temperatures which may be in excess of product design, for
example: candles, plastic or pictures. This can cause melting, deformation,
discolouration or premature failure of T.V. and radio components.
Painting:
Special care is recommended by the Master Painters and Decorators
Association, when painting the replace surrounds, to select and apply
a quality Alkyd sealer prior to the applying of latex paints. This is to
prevent leaching of water from evaporation and causing a brownish
staining effect to paint over coats.
