run to the wall ange of the vent termination is 168", this would be
an acceptable installation.
If the vertical dimension from the hearth is 48" and the horizontal
run to the wall ange of the vent termination is 72", this would be
acceptable installation.
If the vertical dimension from the oor of the replace is 60" and
the horizontal run to the wall ange of the vent termination is 144",
Vent terminations must not be recessed in walls or siding.
All through-the–wall terminations within 3’ of the replace must
have a Montigo Heat Shield (RHS101) installed. See

Rear Vent Venting Graph for wall mounted terminations.
If your installation does not fall
within the venting graph parame-
ters, please contact a local Montigo
Dealer for Power Venting options.
Rear Vent
All dimension lengths for vertical or horizontal runs are measured
from centre of the vent pipe.
Venting runs must fall within the limits set by the venting graphs,
see Figure 14.
Fireplace must be converted to Rear Vent conguration prior to
running vent, see Figure 8 and 8a.
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 with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
If the vertical dimension from the hearth is 120" and the horizontal
run to the wall ange of the vent termination is 138", this would be
an acceptable installation.
If the vertical dimension from the hearth is 48" and the horizontal
run to the wall ange of the vent termination is 96", this
If the vertical dimension from the oor of the replace is 72" and
the horizontal run to the wall ange of the vent termination is 120",
Unacceptable vent run
within shaded area.
Acceptable vent run
within non-shaded area.
WARNING:
An inspection of the explosion relief appers and door
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.

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 Waterproong Consultant
for further recommendations.
The following components and associated Montigo part numbers for
installation of a roof or wall mounted termination.
Use of non-Montigo parts will 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
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.

The * gas valve may be connected to a wall switch. Do
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 connect any external
power to the remote switch.
Refer to for wiring requirements.
The switch location must not exceed 30' from the replace.

Installation
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 21 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.
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.
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:
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, discoloration 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.
NOTICE
XG0147 - 011912.1
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 22.
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.
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.
Combustible surrounds.
Do not operate this fireplace without the glass door or with a broken glass door.
NOTICE
Do not use ammonia based or abrasive cleaners on the glass, they will permanently
etch the surface. Use an approved gas fireplace glass cleaner such as Kel-Kem or
White off.
NOTICE
Side wall clearances are 3". Combustible surrounds may be installed
with 3" clearance to the side of the replace as shown in .
WARNING!
When covering the upper metal portion of the replace, (as shown,
Fig.22) with a non-combustible material : The decorative
facing materials may be subject to temperatures in excess of 250° F.
This should be considered when selecting facing materials.
