PREPARE THE FIREPLACE
Note: This fireplace is shipped as a standard see-thru model. When a pier model is desired, a pier conversion kit is used and
installed later in this manual.
Follow the instructions below for glass assemblies, regardless of which model you are installing:
REMOVE THE GLASS ASSEMBLY: Figure 2.
Figure 2
FIREPLACE ‘FRONT’ SIDE:
A. Locate the spring-loaded 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
(A).
D. Set aside where it will not be broken.
FIREPLACE ‘BACK’ SIDE:
A. Locate the latches securing the glass assembly (under the firebox).
B. Flip the back of the latch down to release the glass assembly.
C. Pull the bottom the glass assembly out and lift up off the tabs at the top (A).
D. Set aside where it will not be broken.
C) POSITION THE FIREPLACE. See Figures 3, 4A, 4B, & 4C.
1. Determine the exact position of your fireplace, vent run and vent
termination cap location.
HORIZONTAL TERMINATIONS
IMPORTANT: The vent termination cap location must comply with
the clearances as shown on page #9. A firestop adaptor is included
with this fireplace and must be used in conjunction with the chimney
system firestop / wall thimble to ensure proper clearances are maintained when the chimney passes thru the wall.
VERTICAL TERMINATIONS
Refer to instructions included with the chimney system for positioning the chimney .
NOTE: Even though the minimum clearance from the top and sides
is 0 ", we recommend that you allow an expansion space of 1/4"
from the top & sides to prevent cracking of face materials due to
expansion of the unit during heating. If expansion room is not left,
the unit will make a loud „banging‟ noise when it heats up or cools
down.
NOTE: When the unit is installed directly on carpeting, tile, or other
combustible materials other than wood flooring, 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 20"
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 hearth is not required. If a hearth is desired, combustible materials
may be used.
CAUTION: COLD AIR TRANSFER AREA. The surrounding outside wall
must be insulated to prevent cold air from entering the room.
Provide for a minimum of 6" of clearance in front of the lower grill. This will
provide adequate space to open and operate the controls behind the lower
grill.
Do not obstruct the upper and lower grill areas to allow proper ventilation air
around the fireplace. Room air enters the convection passageway at the
lower grill, and exits out the upper grill. DO NOT BLOCK THIS PASSAGE.
NOTE: Due to high temperatures, this unit should be located out of
traffic areas and away from furniture and draperies.
SEE-THRU INSTALLATIONS:
Rough opening dimensions differ on the „front and back sides‟. The
opening on one side must be a minimum of 38" wide to allow adequate room to slide the unit into position. See page #8.
NOTE: The control valve assembly may be rotated so that it is accessible from the opposite side from which it was manufactured. Refer to
page #15.
PAGE 7
HORIZONTAL TERMINATIONS:
1. Determine width & depth of the hearth (optional).
2. Determine the vent run and termination cap location. If possible, place the fireplace in such a manner that the piping will be placed between two studs
so additional framing is not necessary.
NOTE: Allow a minimum of 18" between the unit and inside wall to comply with minimum termination requirements. See pages #8-#11 for
horizontal termination guidelines.
3. Cut a hole for the wall thimble, 11 ½" high x 10 ½" wide. The top of this hole must be a minimum:
#700 Series Flexible Vent System: 46" * above the height of the optional hearth.
Rigid Pipe: 47 1/4" * above the height of the optional hearth.
* IMPORTANT: This measurement is determined by the vertical and horizontal length of the venting application desired. The measurement
is to the TOP of the pipe. Please refer to information below through page #14 of this installation manual for requirements and restrictions.
4. Rough in the wall enclosure.
SEE-THRU INSTALLATIONS:
Rough opening dimensions are: Front face - 36 ½" wide x 32 ½" high Back face - 38" wide x 32 ½" high (above the height of the optional hearth). Depth
is determined by the thickness of face materials being used. IMPORTANT! The fireplace depth is 20". See Figure 3 below.

PIER INSTALLATIONS: Refer to Figures 4A & 4B. Rough opening dimensions are 36 1/4" wide x 32 1/2" high (above the height of the optional hearth).
Depth is determined by the thickness of facing materials being used. IMPORTANT! The fireplace depth is 20".
