VENTING GUIDELINES
IMPORTANT: THIS FIREPLACE IS APPROVED FOR USE ONLY WITH ONE OF THE FOLLOWING
DIRECT VENT SYSTEMS. THESE SYSTEMS MAY BE USED FOR HORIZONTAL OR
VERTICALTERMINATIONS.
- #844 DIRECT VENT TERMINATION KIT - for terminations of 3' or less.
- #845 DIRECT VENT TERMINATION KIT - for terminations greater than 6' but less than 8'.
- #846 DIRECT VENT EXTENSION KIT-6'
- SIMPSON DURA-VENT DV-GS DIRECT VENT CHIMNEY SYSTEM - 5" X 8"
- AMERI-VENT DIRECT VENT CHIMNEY SYSTEM - 5"X 8"
Refer topages #8- #13for complete venting installation instructions / requirements.
CLEARANCES:
Minimum clearance to combustible material:
From fireplace sides & back: 0" From heat outletto 8" mantel(or see Figure 1): 13"
From fireplace top stand-off: 0" From glazing (glass)to adjacent sidewall: 12"
To flooring: 0" From fireplace to enclosure ceiling: 4"
From #800 Series flexible chimney: 2" From Dura-Vent chimney system: 1"
NOTE: Eventhoughtheminimumclearancefromthesidesandbackis0",werecommendthatyouallowan expansion
space of 1/4" from the sides and back. If this expansion space is not left, the fireplace will make a loud
‘banging’noisewhen it heats upor cools down and cracking of anyface material usedmay occur.

A) DETERMINE LOCATION - Figure 2A.
1. Determinethe exact positionof your fireplace. If possibleplace the fireplace in such a manner
that the piping will beplaced between two studs so additional framingis not necessary.
2. This fireplace may be installed on either the outside or inside of an exterior wall. See Figure 2A.
The location of doors, windows, soffits / overhangs, etc. must be considered in relation to where
the venttermination cap is tobe located. Refer toFigure 2B, page #5.
3. Ensure the proper clearances are maintained as outlined on page #3.
4. If theoptional heat ducts are used, theirlocation must be considered in relation to the location of
the fireplace.
The heatducts may be vented into the same room as the fireplaceor may be ventedtoother
rooms. A maximum run of 20 ft. for each duct is recommended.
Venting should be completed before framing the fireplacein. Refer toinstructions included in the
#970 duct kit for complete installation requirements.
CAUTION: 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 fireplace should be located out of
traffic areas and away from furniture and draperies.

TERMINATION VENT CAP LOCATION:
This gas appliance must not be connected to a chimney flue serving another type of appliance.
IMPORTANT!
HorizontalTerminationsusingeitherthe#800SeriesDirectVentSystem,SimpsonDura-VentDV-GSChimneySystemorAmeri-VentDirect
VentSystem must follow the clearances to doors, windows, and ground level as shown below for proper vent cap location.
GENERAL:
1. Terminations against vinyl siding must use a vinyl siding protector. Follow instructions included.
2. DO NOT RECESS TERMINATION KIT INTO OUTSIDE BUILDING MATERIALS -i.e.: brick, stone,etc.. If necessary,extendframing so
that termination kit will be exposed once building materials are installed.
3. Vent termination must not be located where it will become plugged by snow or other material. The flow of combustion and ventilation air
must be not obstructed.

B) FRAME & POSITION THE FIREPLACE
1. Frame an opening for the firestop / wall thimble. The location of this opening is determined by your venting
specifications. Refer to the information below.
Figure 3
TYPICAL HORIZONTAL INSTALLATIONS:
Dimensions are 12 1/2" wide x 12 1/2" high when using the #800
series direct vent kits and 11" X 11" when using the Dura-Vent
chimney system. The top of this opening must be a minimum of
45" * above the height ofthe hearth (optional). See Fig. 3. Refer to
pages #8-#13 for additional venting specifications.
*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. Refer to pages
#8 - #13 of this installation manual for requirements and
restrictions.
2. Rough in the wall enclosure. The minimum rough
opening dimensions are 42 1/2" wide, 40 1/4" high and 21"
deep. Build the hearth to the desired size and height. See
Figure 4.
NOTE: When the fireplace is installed directly on carpeting,tile, orothercombustible materialsother than wood flooring,itmustbe
installed on a metalor wood panelextending the fullwidth anddepth ofthe fireplace. The minimum for the supportplatform under
the fireplace is 42"wide by19"deep. Ifmasonry 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 fireplace to support the added weight.
NOTE: A hearth is not required. Ifa hearth 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 for opening to
operate the control valve. Do not obstruct the upper and lower grill areas to allow proper ventilation air around the fireplace. Air
enters the fireplace at the lower grill and exits at the upper grill. Do not block this passage.
Figure 4
3. Place the fireplace into position.

4. REMOVE THE GLASS ASSEMBLY.
A. Locate the spring-loaded handles securing the glass assembly (under the firebox).
B. Pull the latch handles out, then down to release the glass assembly.
C. Pull the bottom of the glass assembly out and lift up off the tabs atthe top.
D. Set aside where it will not be broken.
E. Remove the log package and klinkers from inside the firebox & setaside for later installation.
