Installing The Fireplace Shell
The fireplace may be installed in any location that maintains proper
clearances to 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:

Framing
* When sheetrock
is not used behind
the fireplace, framing depth may be
reduced to 14 3/4"
Figure 2. Framing dimensions.
Front View
Rear Vent
Figure 1. Fireplace dimensions.
Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The ME38-ODV-2 clearances to combustible materials are:
Top - Rear Vent* 7 ¼"
Top - Top Vent*** 32"
Back 0"
Side 1 ½"
Floor 0"
Mantle** 12"
* Clearance from the top of the fireplace to a combusti-
ble ceiling within the fireplace enclosure.
** Refer to page 10.
*** 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
over the elbow, the Top Clearance is 32".
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.

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 (ME38-ODR-
2), the minimum clearance from the top of the fireplace to a shelf is
7 ¼". For Top Vent models (ME38-ODT-2), the minimum clearance
when using the CRS30 is 15". (Minimum 1" clearance must still be
maintained around the vent pipes.)

Installation
Installing The Gas Line
The gas line must be installed before finishing the ME38-ODV-2 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.
The appliance and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure testing
of the gas supply piping system at test pressures equal to or less than
1/2 psig (3.5 kPa).
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.
Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
ME38-ODV-2 fireplaces are certified for use with Montigo Stand-
ard 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 with no vertical rise is 3
feet.
Flex vent sections over 3 feet must fall within the limits set by the
venting graph and must have a minimum vertical rise of 3 inches
per foot of flex.
Solid vent sections may be cut less than half way from the tapered
end
Venting components can be used in any combination of solid/rigid
pipe or flex pipe and in any orientation (Male connectors can face
in any direction)
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,
Installing The Remote Switch
The ME38-ODV-2's gas valve, located behind the lower brass trim,
may be connected to a wall switch. The valve generates its own
power on a millivolt circuit. Use only low voltage wire, and DO
NOT connect any external power to it.
Refer to Figure 26 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.

Installation
Top Vent Venting Runs
For the ME38-ODV-2 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 120", this would be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is
72" and the horizontal run to the wall flange of the vent
termination is 84", this would NOT be an accept-
able installation.
Top Vent
Heat Shields
Due to high flue temperatures, heat shields are required on all 38
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.
