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.

Page 1

WARNING: Do not use this fireplace if any part has been under water. Immediately call a qualified service
technician to inspect this appliance and to replace any part of the control system and any gas control which
has been under water.

WARNING: DO NOT REPLACE THE 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.

IMPORTANT:

NON-COMBUSTIBLE FACI NG MATERIAL MAY BE APPLIED OVER THE FACE. TO PREVENT THE
FACING MAT ERIAL FROM CRA CKIN G AND FAL LING OF F DUE TO EXPA NSION OF THE FAC E WHE N
HEATED, DO NOT ATTACH FACING MATERIAL DIRECTLY TO THE FACE OF THE FIREPLACE.

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 DIRE CT V E N T T E RMINAT IO N KIT - fo r te rminatio n s o f 3 ' or le s s.

- #84 5 DIR ECT VEN T TE RM INAT ION K IT - for te r mina tio ns gr e a te r th a n 6' bu t le s s th a n 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 to pages #8- #13 for complete venting installation instructions / requirements.

CLEARANCES:

Minimum clearance to combustible material:

From fireplace sides & back: 0" From heat outlet to 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: Even though the minimum clearance from the si des and back is 0", we recommend that you allow an expansion

space of 1/4" from the sides and back. If this expansion space is not left, the fireplace will make a loud
‘banging’ noise when it heats up or cools down and cracking of any face material used may occur.

A) DETERMINE LOCATION - Figure 2A.

1. Determine the exact position of your fireplace. If possible place the fireplace in such a manner
that the piping will be placed between two studs so additional framing is 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 vent termination cap is to be located. Refer to Figure 2B, page #5.

3. Ensure the proper clearances are maintained as outlined on page #3.

4. If the optional heat ducts are used, their location must be considered in relation to the location of
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 fireplace in. Refer to instructions 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!

Horizontal Terminations using either the #800 Se ries Di rect Ve nt Syst em, Simp son Dura-Vent DV-GS Chimney System or Ameri-Vent Direct
Vent System 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 TERMI N A TIO N K IT I N TO O U TSI D E B U ILDING MATER IALS - i.e.: brick, stone, etc.. If necessary, extend framing 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 m ust be a m inim um of
45" * above the height of the hearth (optional). See Fig. 3. Refer to
pages #8-#13 for additional venting specifications.

*IMPORTANT: This measurement is determined by the vertical
heig h t a n d ho riz o n ta l le n g th of the ve n ting a p p lic a tio n de sire d.
The measurement is to the TOP of the pipe. Refer to pages
#8 - #13 of this installation manual for requirements and
restr i ct i ons.

2. Rou g h in the w all enclo su re. 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, 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 fireplace. The minimum for the support platform under
the fireplace is 42" wide by 19" deep. If masonry is to be used, (optional), prepare the necessary foundation for the masonry load.
Wh en mas o nry c o n stru c tio n is b e ing u se d , a linte l must b e u se d o v er the top o f th e firep la ce to s u pp o rt th e a d d e d w e igh t.

NOTE: A hearth is not required. If a hearth is desired, combustible materials may be used.

NOTE: P ro v id e for a minim u m of 6 " o f cle a ra n ce in fro n t o f the lo w e r g rill. Th is will provid e a de q u a te sp a c e fo r o p en in g to

Ma ximum v e rtica l rise fro m ap p lian c e ou tle t: 4 0 ft.

IMPORTANT: Straight vertical terminations must use
the in c lu d e d res tr ic to r plate fo r v e n t runs 1 5 ' - 4 0 '.

ELBOWS:

o o

(1) 45 elbow at start & (2) 90 elbows included within the
maximum vent runs. Each additional elbow reduces the
ma ximum h o riz o n tal d ista n c e b y 5 '.

FOR SIMPS ON DU R A-VEN T D V-GS & AMERI-VENT 5” X
8” DIREC T V EN T SY ST EMS - Follow installation

40 ft. 2 - 90-degree elbows may be
used within the 40 ft. vertical vent run.

Vent runs of 15' - 40' must install the
restrictor plate included with this
fireplace.

Figure 6 20 FT. MAX. HORIZONTAL RUN

Horizontal terminations: The minimum vent run directly off the fireplace is 6". Connect to a 45­degree elbow prior to attaching to the fireplace to ensure the chimney is positioned
horizontally. 2 - 90- degree e lbows may be used wit hin the maxi mum 20 ft. hori zontal ve nt run.
For each additional elbow, the maximum horizontal distance must be reduced by 5'.

IMPORTANT:
1/4" RISE PER HORIZONTAL
FOOT MUST BE MAINTAINED.

VERTICAL TERMINATIONS:

WHEN VERTICALLY TERMINATING THE MINIMUM CHIMNEY HEIGHT ABOVE THE ROOFLINE IS
DETERMINED BY THE FOLLOWING CHART:
