CAUTIONS
Due to its high operating temperatures, the appliance should
be located out of traffic & away from furniture and draperies.
Children and adults should be alerted to the hazards
of the high surface temperature, which could cause
burns or clothing ignition.
Young children should be carefully supervised when
they are in the same room as the appliance.
Clothing or other flammable materials should not be
placed on or near the appliance.

Installing The Fireplace Shell
The fireplace may be installed in any location that is free of air
conditioning ducts, electrical wiring and plumbing. Safety, as well
as efficiency of operation, must be considered when selecting the
fireplace location. Try to select a location that does not interfere
with room traffic, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.
The fireplace dimensions are shown below:

* When sheetrock
is not used behind
the fireplace, framing depth may be
reduced to 15"

Clearances
The ME34-DV clearances to combustible materials are:
Top - Rear Vent* 7"
Top - Top Vent*† 13"
Back 0"
Side 1"
Floor 0"
Mantle** 10"
* Clearance from the top of the fireplace to a combusti-
ble ceiling within the fireplace enclosure.
** Refer to page 11.
† If special short elbow (SEL90) is used with the Low
Clearance Sleeve (CRS30) the Top Clearance is 13".
If the standard elbow (MEL90) is used with the Low
Clearance Sleeve (CRS30) the Top Clearance is 15".
If the Low Clearance Sleeve (CRS30) is NOT used
over the elbow, the Top Clearance is 35".
Unprotected combustible walls which are perpendicular to the
fireplace opening, must not project beyond the shaded area shown in
Figure 19b.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapour barrier. This will
reduce the possibility of a cold-air convection current on the fireplace.
Part No. XG0105A
Figure 3. Corner framing dimensions.
When installing a shelf over the top of the fireplace, the following
guidelines must be adhered to: For Rear Vent models (ME34DR), the
minimum clearance from the top of the fireplace to a shelf is 7". For
Top Vent models (ME34DT), the minimum clearance is 13". (Minimum
1" clearance must still be maintained around the vent pipes.)

WARNING:
When this appliance is installed directly on carpeting, tile or any
combustible material other than wood flooring, it must be installed
on a metal or wood panel extending the full width and depth of
the appliance.

Installation
Installing The Gas Line
The gas line must be installed before finishing the ME34-DV Fireplace. Natural Gas requires a minimum inlet gas supply pressure of
5.5" W.C. & a manifold pressure of 3.5" W.C. Propane Gas requires a
minimum inlet gas supply pressure of 11" W.C. & a manifold pressure
of 10" W.C. Provision must also be made for a 1/8" N.P.T. plugged
tapping and be accessible for test gauge connection immediately
upstream of the gas supply controls to the appliance. The fireplace
gas connection and the main operating gas valve is located behind
the removable brass trim at the bottom of the unit and need only be
attached to the gas line with an approved fitting, as required by the
applicable installation codes.
Figure 5. Gas line access.
During any pressure testing of the gas supply piping that excedes 1/2
psig (3.5 kPa), the appliance and its individual shutoff valve must be
disconnected from gas supply system.
When pressure testing the gas supply piping system at test pressures
of less than or equal to 1/2 psig (3.5 kPa), the appliance must be
isolated from the gas supply piping system by closing its individual
manual shutoff valve.
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
ME34-DV fireplaces are certified for use with Montigo Standard
Series (4" / 7") venting components
Minimum 1" clearance to combustibles required for vent pipes
Use only certified Montigo vent components. (Use of other parts
will void the Montigo warranty, and may impede the operation of
the fireplace.)
All joints must be secured with a minimum of two screws per joint
Vent terminations must not be recessed in walls or siding
Horizontal runs must be supported by a minimum of two supports
per horizontal run. A minimum of one screw on each side of support is also required
Flex vent sections may be stretched up to 50% of their total length
(eg. a 24" section may be stretched to 36")
Maximum horizontal run for a flex section is 3 feet.
Solid vent sections may be cut less than half way from the tapered
end
Vent Terminations
Selecting A Termination Location
Choosing your vent termination location will help to determine
whether you need to use a top vent or rear vent fireplace. Figure 6,
below, shows typical fireplace locations and the venting options they
provide.
For a more detailed diagram of allowed termination locations, see
Appendix B.
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 flame of any kind to test for leaks.
Installing The Remote Switch
The ME34-DV's gas valve, located behind the lower brass trim, may
be connected to a wall switch. The valve generates its own power.
This is a millivolt circuit. Use only low voltage wire, and DO NOT
connect any external power to it.
Refer to Figure 28 for wiring requirements.
Note: The switch location must not exceed 30' from the fireplace.
Page 4
Figure 6. Fireplace locations and vent terminations.
Cautions:
Vent terminations can be very hot. If the termination is less
than 7 feet above a public walkway, it should be fitted with a
certified Montigo Heat Guard. (Part no. MTKOG)
Do not obstruct, or attempt to conceal, the vent termination.
These actions will affect the operation of the fireplace, and
may be hazardous.
In heavy snow areas, take extra care to prevent snow buildup
from obstructing the vent termination.

Installing Terminations with Built-In Frames
MTO-3F
1. Frame the termination opening to 11" x 11".
2. Fasten the termination to the studs using a minimum of 4
screws.

2. Attach to the faceplate of the termination using four sheet metal
MTKOG
Installing Heat Guards over Terminations
1. Ensure that the two long mounting brackets are facing the bot-
tom of the termination. (See inset). This will provide more heat
protection at the top of the termination, where temperatures are
highest.
MTO-3
1. Frame the termination opening to 12" x 12".
2. Fasten the termination to the studs using a minimum of 4 screws.
Installing Terminations with MOSR Frames
MOSR
MTO-3
1. Frame the termination opening to 12" x 12".
2. Fasten the MOSR frame to the interior side of the studs using a
minimum of 4 screws.
3. Insert the termination into the MOSR frame as shown here, and
attach by screwing through the four pilot holes in the termination.

Installation
Top Vent Venting Runs
For the ME34-DV Top Vent, there are two types of installations: A)
Through-The-Wall Installations and B) Vertical (Through-The-Roof)
Installations.
A) Through-The-Wall Installations
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
fireplace's combustion.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 7) 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 84" and
the horizontal run to the wall flange of the vent termination is 36", this would be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 90" and
the horizontal run to the wall flange of the vent termination is 126", this would be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 78" and the horizontal run to the wall flange
of the vent termination is 108", this would NOT be
an acceptable installation.
Top Vent
Heat Shields
Due to high flue temperatures, heat shields
are required on all 34 Series Modular Direct
Vent installations (except those with vertical
terminations) at the point where the venting
connects to the termination. With the heat
shield, vent clearances can be maintained
at 1".
Figure 8. Heat Shield. Install by sliding over the vent pipe where it
passes through combustible construction.
