COMMONWEALTH OF MASSACHUSETTS
INSTALLATIONS
WARNING: This Product Must Be Installed By A Licensed
Plumber Or Gas Fitter When Installed Within The
Commonwealth of Massachusetts.
IMPORTANT: Installation of a CO detector is required in
the fireplace room.
WARNING: DO NOT REPLACE THIS BURNER WITH
ANY OTHER SIZED BURNER. REPLACEMENT WITH
AN UNAUTHORIZED BURNER CAN RESULT IN
TEMPERATURES EXCEEDING THE LIMITS FOR THIS
FIREPLACE AND VOID YOUR WARRANTY.
DUE TO HIGH TEMPERATURES, THIS FIREPLACE
SHOULD BE LOCATED OUT OF TRAFFIC AND AWAY
FROM FURNITURE AND DRAPERIES.
YOUNG CHILDREN SHOULD BE CAREFULLY
SUPERVISED WHEN THEY ARE IN THE SAME ROOM
AS THIS FIREPLACE.
CHILDREN AND ADULTS SHOULD BE ALERTED TO
THE HAZARDS OF HIGH SURFACE TEMPERATURES
AND SHOULD STAY AWAY TO AVOID BURNS OR
CLOTHING IGNITION.
CLOTHING OR OTHER FLAMMABLE MATERIAL
SHOULD NOT BE PLACED ON OR NEAR THE
APPLIANCE.
MASONRY CONSTRUCTION: A lintel, PART #788B,
must be used to support the added weight when
masonry construction is used. See page #19 for
additional information.
IMPORTANT: DO NOT PLACE FACING MATERIAL
OVER THE EXTERIOR FACE. THE FACE WILL
EXPAND WHEN HEATED AND WILL CAUSE
CRACKING OF THESE MATERIALS. FAILURE TO
FOLLOW THESE INSTRUCTIONS WILL VOID YOUR
WARRANTY.

Minimum clearance to combustibles:
Top Stand-off: 0" From flue vent:: 1"

Figure 2
A) DETERMINE LOCATION. Figure 3A.
Determine the exact position of your fireplace.
1.
2. This fireplace may be installed on either the outside
or inside of an exterior wall. See Figure 3A for
various installation options.
3. Horizontal Terminations: 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.
4. The location of doors, windows, soffits/overhangs,
etc. must be considered in relation to where the
vent termination cap will be located.
5. Vertical Terminations: Follow instructions
included with the Simpson Dura-Vent DV-GS for
position of chimney. The #923-C adaptor must be
used.
6. All clearances to combustible requirements must be
maintained. Follow clearance requirements above.
7. 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 ro oms. A
maximum run of 20 ft. is recommended.
Venting should be completed before framing in the
fireplace.
Refer to the instructions included with the #970 duct
kit for complete installation requirements.
8. If using the optional fan kit, 115V wiring should be
run to the lower left of the fireplace by a qualified
technician. A removable electrical box 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 fireplace.
9. CAUTION - COLD AIR TRANSFER AREA. The
surrounding outside walls must be insulated to
prevent cold air from entering the room.

NOTE: DUE TO HIGH TEMPERATURES, THIS FIREPLACE SHOULD BE LOCATED OUT OF TRAFFIC
AREAS AND AWAY FROM FURNITURE AND DRAPERIES.

NOTE: Even though the minimum clearance from the back wall is 0", we recommend that you allow
an expansion space of 1/4" from the back wall to allow for heat expansion. If this room is not
left, the fireplace may make a loud "banging" noise when it heats up or cools down.
10. Cut an opening for the wall thimble, 9 ½” x 9 ½”. The top of this opening must be a minimum of 47 1/4"*
above the height of the hearth (optional) or floor the fireplace is setting on. See Figure 3B.
*Important: This measurement is
determined by the vertical height &
horizontal length of the venting application
TOP
desired. The measurement is to the
the pipe. Please refer to pages #5 - #10 of
this installation manual for requirements
& restrictions.

11. Rough in the wall enclosure (Figure 3C). Minimum rough opening dimensions are 52” w x 31 1/4" h. Depth is
determined by your specific application. Build the hearth, if used, to the desired size and height.
NOTE: A metal or wood panel extending the full width and depth of the fireplace (minimum size is 51 5/8” wide
x 18 ½" deep) must be placed under the fireplace when the fireplace is to be installed directly on carpet, tile or other
combustible materials other than wood flooring.
If masonry is to be used (optional), prepare the necessary foundation for the masonry load. When masonry
construction is being used, a lintel, part #788B, must be used over the top of the fireplace to support the added
weight.
NOTE: Provide for a minimum of 6" (152
mm) of clearance in front of the lower grill.
This will provide adequate space for opening
the lower grill to access control panel.
Figure 3C
NOTE: A hearth is not required. If a hearth is desired, combustible materials may be used.
Do not obstruct the upper and lower grill areas to allow proper ventilation air around the fireplace. Air enters the
fireplace through the lower grill, and exits out the upper grill. Do not block this passage.
12. Place the fireplace into position.
NOTE: DO NOT PLACE FACING MATERIAL OVER THE EXTERIOR FACE. THE FACE
WILL EXPAND WHEN HEATED AND WILL CAUSE CRACKING OF THESE MATERIALS.
FAILURE TO FOLLOW THESE INSTRUCTIONS WILL VOID YOUR WARRANTY.
