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 Power Vent installation. Refer to page 4 - Vent Installation
for more information.

Figure 3. Minimum Corner framing dimensions, using a 45° elbow.
When installing a shelf over the top of the replace, the following
guidelines must be adhered to: For Rear Vent applications the
minimum clearance from the top of the replace to a shelf is 9". For
Top Vent applications, the minimum clearance is 17 1/2". (Minimum
2" clearance must still be maintained around the vent pipes.)
Clearances
These clearances apply to all dimensions except the framed opening,
where the clearance to combustibles is 0". The HT34-PV Series
clearances to combustible materials are:
HT34-PV
Top - Rear Vent *
Top - Top Vent
Back
Sides
Floor
Mantle**
17 1/2”
* Clearances from the top of the replace to a combustible ceiling
within the replace enclosure.
** Refer to page 14.
Unprotected combustible walls which are perpendicular to the replace
opening, must not project beyond the shaded area shown in Figure 25.
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.

Installation
Figure 5b. Gas line access.
HT34-PV Series Power Vent Gas Fireplace
Installing The Gas Line
The gas line must be installed before nishing the HT34-PV Series
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 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 5b.
• 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.

Vent Installation
This section covers the installation of direct venting and terminations.
Installation Requirements
H
T34D-PV Series fireplaces are certified for use with Montigo Standard
Series (4" / 7") venting components.
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 certied 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")
Solid vent sections may be cut less than half way from the female 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 replace. Figure 6a, below,
shows typical replace locations and the venting options they provide.
For a more detailed diagram of allowed termination locations, see Ap-
pendix A.
Burner Tray Gasket
The appliance and its individual shut-off 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 shut-off 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 ame of any kind to test for leaks.
Part No. XG0530 - 041510
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. 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.
Use Montigo Vinyl Heat Shield (Part no. VSS) when using on ap-
plications with vinyl siding to guard against possible damage.

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.
3. If installing the termination over Vinyl siding, Use the VSS Termination
shield. Montigo Installation document, XG1301.

Installing The Standoffs
To avoid elevated mantel temperatures, all HT34-PV Series gas
replaces are 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 6" clearance.
