Introduction
Rating label sample: Natural Gas Sample Shown
IMPORTANT MESSAGE: SAVE THESE INSTRUCTIONS
The I-Series insert replaces must be installed in accordance
with these Instructions. Carefully read all the instructions in
this manual rst. Consult the Local Gas Branch to determine
the need for a permit prior to starting the installation. It is
the responsibility of the installer to ensure this replace is
installed in compliance with the manufacturers instructions
and all applicable codes.
Installations into a Solid Fuel Burner Fireplace or a Factory
Built Fireplace
This gas appliance has been tested and approved for installation
into any approved masonry or factory built solid fuel replace,
in which this gas insert will t. In the event that the vertical
height of the factory built replace is to low and that the removal
of some components such as the ue bafe, ue damper or
surround panels will facilitate the installation of the gas insert,
such components can be removed on the condition that:
1). The removal of such components in no way compromises
the structural integrity of the unit.
2). A Sticker, supplied by the installer, showing this information
is prominently afxed to the rebox.

Install Dimensions:
The install size requirements of your replace insert are dependent on several factors. Gas line location, electrical connection and gas
line type can play into what the minimum installation size can be. The diagram below illustrates the smallest possible size requirement
of this model. Please take into consideration these other factors when determining if this appliance will t into your masonry or
manufactured replace.

The 34DFID-S Insert is designed and built to be installed into masonry or manufactured replaces. There is no requirement to have
a non-combustible hearth in front of the unit. Clearances to the underside of the mantel or sidewall are measured from the edge of
the door/screen front. The Mantel is shown as 10” maximum at a distance of 23” minimum from the door edge top. The mantel can
be extended further providing that you increase the height proportionately. For instance, if you want a mantel that is 2” beyond the
10” minimum, you have to install it 2” above the 23” minimum.

Figure 1 Sec.3
Vent Congurations
This appliance can only be vented vertically. The minimum vent
height measured from the oor under the unit to the bottom of the
termination is 10’. The maximum height that a vent can extend is
36’. This unit uses 4” x 3” Co-linear venting. This is a direct vent
unit and as such requires that both intake and exhaust vents are
connected and operational. Using existing chases as a partial vent
mechanism is not allowed. Due care is required to ensure that all
vent components are properly connected and sealed. Care must
also be taken when installing ashing or termination caps to make
sure that the structure of the building cannot be subject to water
penetration. Proper roong and chimney nishing techniques
must be used.
Steps for vent connection
** Before installing the venting system, make sure that any dampers
or bafe plates in the replace are removed or do not present any
hindrance to your installation **
1). Determine the length of ex venting that will be required. Cut
2 lengths a couple of feet longer than you anticipate needing. The
length of these needs to be determined after the vent is stretched
out. Flex venting generally comes compressed and needs to be
stretch out to meet the lengths as specied.
2). From the roof, attach the Vent Lengths to the Adaptor. Don`t
forget to have the Flashing placed between the Flex Vent and the
Adaptor before attaching the Flex Vent.
3). Using commercial grade sealant around the perimeter of the
Collars of theAdaptor, use a minimum of 3 Tech screws in each Vent.
4). Install the Termination to the top of Adaptor. Use a minimum of
4 tech screws to attach the Termination to the Adaptor.
5). Feed the Flex Venting down the chimney until the Adaptor is
situated near the top of the Chimney. Use a commercial grade of
sealant between the Flashing and the Chimney top. Fasten the
Flashing to the top of the Chimney using a fastening method that
will properly secure the ashing permanently.
6). Attach the Adaptor to the top of the Flashing using 4 tech
screws. Seal around the perimeter of the Adaptor where it meets
the Flashing.
7). From inside the house check how long the vents protrude into
the Fireplace. Read the section on installation where fuel supply
pressure checking needs to be done. This procedure can be
done at this point by installing the venting to the appliance prior
to pushing the appliance into the replace cavity.
8). Once pre-installation steps have been completed, trim the vent
length to the correct length for installation. The Correct length will
leave the Flue Collar Slide Plate suspended around 18-19 inches
from the oor of the Fireplace.
9). Remove the Flue Collar Slide Plate from the appliance. Attach
both ex ends to the Flue Collar Slide plate. Use a commercial high
temp sealant around the Flue Collars on Flue Collar Slide Plate
before installing the Venting. Use a minimum of 3 tech screws to
properly secure the Venting to the Flue Collar Slide Plate.
** Make certain that the Exhaust and Intake Vents are connected
to the correct collars on the Flue Connection Plate. If they
are connected in reverse, this unit will not operate and re-
installation will be necessary. **

** For clarity, the pictures in this section show the Fireplace Insert in
an open room. You will be performing these tasks in the Fireplace
as you complete this installation **
10). Using the Door Opening Tool provided with the Fireplace Insert,
insert the tool through the Outer Shell of the Fireplace Insert. You
will be inserting this tool through a keyhole on front edge of the Flue
Collar Slide Plate.
11). The Flue Collar Slide Plate needs to be engaged into the Slide
Plate Retainers as you pull it forward.
12). You will slowly slide the Fireplace Insert back into the Fireplace
Cavity. At the same time, you will be pulling the Flue Slide Plate
forward onto the Fireplace Insert.
** Be extremely careful that the Gasket between the Fireplace
Insert and the Flue Collar Slide Plate isn`t damaged and remains
in the correct position. Failure of this gasket will greatly diminish the
operation of this appliance. **
14). Once the Flue Collar Slide Plate is within 1" of the front, Use
the 1/4" NC screw supplied and secure the Flue Collar Slide Plate
to the front of the Fireplace Insert
13). Make certainthatwhen the FlueCollarSlidePlate comes forward
that the tab at the back of the appliance engages into the Flue Collar
Slide Plate. Without this engagement, the Flue Collar Slide Plate will
not seal against the Gasket and the unit will not function.

Door Installation & Removal
This appliance is supplied with a safety screen installed. The
Safety Screen is attached to the replace door using 4 screws,
and can be removed when necessary for outer glass cleaning.
The Fireplace Door is attached to the Firebox by way of 2 tabs
mounted to the top of the Firebox and by 2 spring loaded retainers
at the bottom underneath the Door. The Retainers at the bottom
of the unit are manipulated using a Door Tool that is supplied with
the unit. The general operation of the Door Retainers is:
