Installation
Installing The Fireplace Shell
The replace may be installed in any location that maintains proper clearances to air conditioning ducts, electrical wiring and plumbing. Safety,
as well as efciency of operation, must be considered when selecting
the replace location. Try to select a location that does not interfere
with room trafc, has adequate ventilation, and offers an accessible
pathway for Direct Vent installation. Refer to page 4 - Vent Installation
for more information.

Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The H52DFN clearance to
unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Fig. 8.
For protection against freezing temperatures, it is recommended that
outer walls of the chase be insulated with a vapor barrier. This will reduce
the possibility of a cold-air convection current on the replace.

WARNING!
When this appliance is installed directly on carpeting, tile or any
combustible material other than wood ooring, it must be installed
on a metal or wood panel extending the full width and depth of
the appliance.
Installing The Gas Line
The gas line must be installed before nishing the H52-DFN Fireplace.
Natural Gas requires a minimum inlet gas supply pressure of 5.5" W.C.
& a manifold pressure of 3.5" 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
replace gas connection and the main operating gas valve is located
behind the removable trim at the bottom of the unit and need only be
attached to the gas line with an approved tting, as required by the
applicable installation codes.
To access the replace gas connection the main burner must be
removed as shown below in gure 3.
• Only use gas shut-off valves approved for use by the state, province,
region, or governing body, in which the appliance is being installed, or
as required by the applicable installation codes.
• Flexible gas connectors must not exceed 3 feet in length, unless it is
allowable within applicable installation codes.

H52-DF Gas Fireplace
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 Standoffs
To avoid elevated mantel temperatures, the H52-DFN gas
replace is required to have the supplied standoffs installed.
The replace is supplied with two standoffs. Bend and install these
standoffs on top of the replace ensuring that the height of the standoff
maintains a 2.5" clearance.
Figure 4. Installing the standoff's.
Installing The Remote Switch
The H52-DFN's gas valve, located behind the lower 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 15 for wiring requirements.
Note: The switch location must not exceed 30' from the replace.
Termination Installation
This section covers the installation of the Various available terminations.
Installing Terminations with Built-In Frames
PTO-3F (5"/8")
1. Frame the termination opening to 11" x 11".
2. Fasten the termination to the studs using a minimum of 4
screws.
Installing Terminations with MSR Frames
MSR
PTO-F (5"/8")
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
Installation Requirements
■
H52-DFN fireplace is certified for use with Montigo Standard Series (5"/ 8")
flexible venting components ONLY.
■ Minimum clearance to combustible construction around the vent pipe
is 1" on all sides, except on horizontal venting where the top of the pipe
must have a clearance of at least 2".
■ Use only certified Montigo flexible 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
■ 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")
■ Flexible Venting components can be used in any configuration, 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 how you
vent your replace. The following gures shows typical replace termination installations and the venting options they provide.
For Detailed diagram of allowed termination locations, see Appendix
Part No. XG0650
MOSR
PTO-F (5"/8")
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
Installing Heat Guards over Terminations
PTKOG (5"/8")
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.
2. Attach to the faceplate of the termination using four sheet metal
screws.
Recessed Termination Installation (DVPV58)
The DVPV58 termination is designed
to be Installed ush with the exterior of
the building. This recessed design uses
5"/8" vent and allows the installation to
be clean and ush so it does not interfere
or have an impact with your architectural
design.
Note: The Louvred grille is not supplied by
Montigo and must be sized accordingly.
We require a MIN 80in/sq free air
movement to adequately allow air to
enter, and exhaust the replace. Also note
the material of the louvre must be able to
withstand high operating temperatures.
Figure 5. Linear Power Vent recessed Termination.
IMPORTANT
The H52-DFN requires a specic volume of atmospheric
interchange to operate properly and efciently.
The replace requires a MIN 80in/sq. air movement ■
to function.
Due to high operating temperatures the louvered ■
grill must be manufactured from a material that will
be capable of withstanding high temperatures.
The grille must also be able to shed water, not ■
allowing any moisture to enter the unit.
Installing The Power Vent
The LDVPV58 Linear Power Vent System must ONLY be used with
a Montigo H52-DFN Direct Vent Fireplace. When selecting Venting
components for use with this Linear Power Vent System, take into consideration the various requirements and limitations in the vent installation
section of the Model's manual:
Models Must Be Equipped with Electronic Ignition (HSI/AF)
Only models equipped with an electronic ignition system may be installed
with the LDVPV58 Linear Power Vent System. The absence of a pilot in
this system, allows for greater exibility on venting requirements.
General Information
This installation section covers installation of the LDVPV58 Linear Power
Vent System ONLY. This system is designed to allow the installation of the
H52-DFN gas replace to function with many years of reliable service.
Specications and instructions pertaining SPECIFICALY to the H52-DFN
replace must be followed. Please read these Installation Operation
and Maintenance Instructions thouroughly and carefully before operating this equipment.
