Before You Begin
IMPORTANT MESSAGE: SAVE THESE INSTRUCTIONS
TheI-Seriesinsert replaces must be installed in accordance with
theseInstructions.Carefullyreadalltheinstructionsinthismanual
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 Factory Built Solid Fuel Burning 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 less
than 20" you may remove some of the components such as the ue
bafe, ue damper or surround panels. These 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 label supplied with your insert is prominently afxed to the
existing replace. This label can be found included in the bag that
contains the back-up batteries for the insert.
The bottom of the existing replace may be removed as long as it
does not compromise the structural integrity of the existing rplace
andyoumaintainamandatoryminimum3/4"clearancebetweenthe
bottom of the insert and the bottom shell of the existing replace.
This can be achieved by using strips of noncombustible material or
by using the leveling bots on the insert.

Clearances:
The 34DFID-L 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 17” 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” maximum, you have to install it 2” above the 17” minimum.

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.

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
CollarsoftheAdaptor,useaminimumof3TechscrewsineachVent.
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 theAdaptor 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). Oncepre-installationstepshavebeencompleted,trimthevent
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). RemovetheFlue CollarSlide Platefrom theappliance.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.
**MakecertainthattheExhaustandIntakeVentsareconnected
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. **

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 is not 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). MakecertainthatwhentheFlueCollarSlidePlatecomesforward
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.
