A) PREPARE THE FIREPLACE
1. REMOVE THE GLASS ASSEMBLY.
See Figure 2.
A. Locate the spring-loaded latch handles
securing the glass assembly (under the
firebox).
B. Pull the handles out, then down to release the
glass assembly.
C. Pull the bottom of the glass assembly out and
lift up off the tabs (at the top).
D. Set aside where it will not be broken.
E. Remove the logpackage from the firebox and
set aside.
Figure 2
B) DETERMINE LOCATION. See Figures 3A & 3B.
1. Determinetheexact positionofyour fireplace.
If possible, place the fireplace in such a
manner that the venting will be placed
betweentwo studsso additionalframingis not
necessary. Determine the width, depth and
height of the (optional) hearth.
2. The unit may be installed on eitherthe outside
or inside of an exterior wall. See Figures 3A &
3B, page #6 for various installation options.
The location of doors, windows,
soffits/overhangs, etc. must be considered in
relation to where the vent termination cap will
be located. Refer to Figure 8, page #10.
All clearances to combustible requirements
must be maintained. Follow clearance
requirements on page #4.
3. If the optional heat ducts are used, their
location must be considered in relation to the
fireplace.
The heat ducts may be vented into the same
room as the fireplace or may be vented to
other rooms. A maximum run of 20 ft. for each
duct is recommended.
Venting should be completed before framing
the unit it.
Refer to instructions included in the #970 duct
kit for complete installation requirements.
4. Ifusingtheoptionalfankit,115Vwiring should
be run to the lower left of the fireplace by a
qualified technician. A removable electrical
access panel with romex connector is located
on the left side of the fireplace. The wiring
should be run prior to enclosing the sides of
the unit.
CAUTION: COLD AIR TRANSFER AREA. THE SURROUNDING WOOD CHASE OF THE OUTSIDE
WALL MUST BE INSULATED TO PREVENT COLD AIR FROM ENTERING THE ROOM.
NOTE: Due to high temperatures, this unit should be located out of traffic areas and away from
furniture and draperies.

5. Cut a hole for the firestop, 9 1/2" x 9 1/2".
The top of this hole must be a minimum of:
- 42 1/2” * (A) - Model #932 DV
- 49 1/2" * (A) - Model #936 DV
above the height of the hearth (optional). (G)
See Figure 4A.
*Important: This measurement is determined by
the vertical height and horizontal length of the
venting application desired. The measurement
is to the top of the pipe. Please refer to pages
#8 - #10 of this installation manual for
requirements and restrictions. Figure 4A
6. Rough in the wall enclosure. The minimum rough opening dimensions are:
Model #932 DV: 25 1/4” high (A)

Build the hearth to the desired
size, and height. See Figure 4B.
Figure 4B
NOTE: When thefireplace isinstalleddirectlyon carpeting, tile,orother combustible materialsotherthan woodflooring,
it must be installed on a metal or wood panel extending the full width and depth of the unit. The minimum for the support
platform under the unit is: Model #932 DV: 18 1/4” deep by 32” wide Model #936 DV: 18 1/4" deep by 36" wide. If
masonry is to be used (optional), prepare the necessary foundation for the masonry load. When masonry construction
is being used, a lintel must be used over the top of the unit to support the added weight.
NOTE: A non-combustible hearth extension is not required. If a hearth extension is desired, combustible
materials may be used.
NOTE: Provide for a minimum of 6" of clearance in front of the lower grill. This will provide adequate space
to open the lower grill and operate the controls.
Do not obstruct the upper and lower grill areas to allow proper ventilation air around the fireplace. Air enters
the unit at the lower grill, and exits at the upper grill. Blocking these passages may result in overheating the
fireplace creating a potentially hazardous situation.
7. Place the fireplace into position.

RESTRICTOR INSTALLATION
The restrictor plate included in the fireplace components
packet can be installed as either a large or small restrictor,
depending on your specific venting configuration.
There are severalfactorswhichcan affect properdraftofthe
vent system and the burner operation of a fireplace.
Installing a restrictor may be necessary to resolve the
problem, even though it may not be required under ‘normal
conditions’.
IMPORTANT: DO NOT INSTALL IF THE VENTING
CONFIGURATION
IS AT THE MINIMUM REQUIREMENTS!

Figure 6A
Figure 6B
To install the restrictor, refer to Figures 7A & 7B and bend the tabs ‘up’ far enough (approximately 80-degrees) so that when
positioned into the exhaust pipe, will create tension to hold itself in place. Do not over bend the tabs! Slide the restrictor into the
exhaust pipe with the tabs pointing toward you. Access to the exhaust pipe can be gained by removing the nuts securing the
exhaust baffle inside the firebox at the top.

Install with the tabs pointing toward you.
IMPORTANT: REPLACE THE EXHAUST BAFFLE AFTER RESTRICTOR INSTALLATION IS COMPLETE. DO NOT OVER
TIGHTEN THE NUTS!
