Installation
Installing The Fireplace Shell
Panorama Direct Vented Fireplace
The fireplace may be installed in any location that maintains 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.
The fireplace dimensions are shown below:
Top View
Framing
Unprotected combustible walls which are perpendicular to the fireplace
opening, must not project beyond the shaded area shown in Figure
13b.
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 2. Framing dimensions.

Clearances
The M38DV-PRC clearances to combustible materials are:
Top* 16"
Back 0"
Floor 0"
Mantle** 6"
Vent 1"
* Clearance from the top of the fireplace to
a combustible ceiling within the fireplace
enclosure.
** Refer to page 8.
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 M38DV-PRC
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 4. 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).
* 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.
For a detailed diagram of allowed termination locations, see Appendix
A.
Installation Requirements
n The M38DV-PRC fireplace uses Premium venting components
with:
5" inner dia. /8" outer dia.
n Minimum 2" clearance to combustibles required for vent pipes
n Use only certified Montigo vent components. (Use of other parts will
void the Montigo warranty, and may impede the operation of the
fireplace.)
n All joints must be secured with a minimum of two screws per joint
n Vent terminations must not be recessed in walls or siding
n 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
n Flex vent sections may be stretched up to 50% of their total length
(eg. a 24" section may be stretched to 36")
n Maximum horizontal run for a flex section with no vertical rise is 3 feet.
n 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.
n Venting components can be used in any combination of solid/rigid
n Solid vent sections may be cut less than half way from the tapered end
n 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)
CAUTIONS:
• Vent terminations can be very hot. National Standards
require that all terminations accessible to the public (below 7
feet from grade level, on balconies, or decks) be installed
with a certified Montigo Heat Guard. (Part no. PTKOG)
• 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.
The M38DV-PRC is equipped with a remote-operated valve for use
with a wall switch. See Figure 19 for information on wiring the switch.
The valve is pre-wired and generates its own power. DO NOT connect
any external power to it.
Note: The switch location must not exceed 30' from the fireplace.

Venting Runs
If your installation requires more than 12" of horizontal venting, some
vertical lift is required. Use the vent graph below to determine an
acceptable vent run. Unacceptable venting can affect the fireplace's
combustion.
n the maximum horizontal vent run is 16 feet
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. 6) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Figure 5b. Installing a PTO-3 termination with the MSR frame.
Installing Terminations with MOSR Frames
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.

Installing Heat Guards over Terminations
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.
Figure 6. Venting Graph.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 60", 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 96" and the horizontal
run to the wall flange of the vent termination is 144", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 48" and
the horizontal run to the wall flange of the vent termination is 120",
this would NOT be an acceptable installation.

Direct Vent Installation
Vent systems that terminate through a wall may comprise up to six
different components:
A - Termination PTO-3 (3" length)
PTO-3F (3" length)
B - Stucco Kits MSR (stucco frame)
MOSR (stucco can)
BSR (brick can)
C - Flex sections PFL-1 (12" section)
PFL-2 (24" section)
PFL-3 (36" section)
PFL-4 (48" section)
D - Solid sections PEXT-1 (12" section)
PEXT-2 (24" section)
PEXT-3 (36" section)
PEXT-4 (48" section)
E - Extensions PXT-5 (5" section)
PXT-10 (10" section)
F - 90° elbow PEL-90F/F
PEL-90M/M
Long Vent Runs:
For longer or more complex vent runs, vertical lift is required. First
ensure that the planned run is acceptable using the Vent Graph. Plan
out the required components using the chart above. You may be able
to use fewer components using the chart below.
Example:
A rigid section and an elbow used in conjunction with 3 ft. flex section
(PFL-3) will, when extended in a chase, allow for a maximum horizontal
run of twelve and one-half feet from the centre of the fireplace to
outside wall and a minimum of 7'6" when retracted in opposite
direction. (See Figure 8 and 9.)
"C" flex sections and "D" solid sections may be used in conjunction with
one another to obtain different possible horizontal length installations.
NOTE: Flex section must not exceed maximum horizontal length of 3
feet.
Short Configurations:
For installations straight through the wall, use a 2" or 5" termination
(see above chart for Part #), and PXT-5 or PXT-10 to achieve the
desired length. The maximum horizontal vent run with no vertical lift is
12".
See Figure 7.
