COMMONWEALTH OF MASSACHUSETTS REQUIREMENTS
NOTE: The following requirements reference
various Massachusetts and national codes not
contained in this manual.
For all sidewall horizontally vented gas fueled equipment installed in every dwelling, building or structure used in whole or in part for residential purposes,
including those owned or operated by the Commonwealth and where the side wall exhaust vent termination is less than (7) feet above finished grade in the
area of the venting, including but not limited to decks and porches, the following requirements shall be satisfied:
INSTALLATION OF CARBON MONOXIDE DETECTORS
At the time of installation of the side wall horizontally vented gas fueled equipment, the installing plumber or gas -fitter shall observe that a hard wired
carbon monoxide detector with an alarm and battery back-up is installed on the floor level where the gas equipment is to be installed. In addition, the installing plumber or gas-fitter shall observe that a battery operated or hard wired carbon monoxide detector is installed on each additional level of the dwelling, building or structure served by the side wall horizontal vented gas fueled equipment. It shall be the responsibility of the property owner to secure the
services of qualified licensed professionals for the installation of hard wired carbon monoxide detectors.
In the event that the side wall horizontally vented gas fueled equipment is installed in a crawl space or attic, the hard wired carbon monoxide detector with
alarm and battery back-up may be installed on the next adjacent floor level.
In the event that the requirements of this subdivision can not be met at the time of completion of installation, the owner shall have a period of thirty (30)
days to comply with the above requirements; provided, however, that during said thirty (30) day period, a battery operated carbon monoxide detector with
an alarm shall be installed.
APPROVED CARBON MONOXIDE DETECTORS
Each carbon monoxide detector as required in accordance with the above provisions shall comply with NFPA 720 and be ANSI/UL 2034 listed and IAS
certified.
SIGNAGE
A metal or plastic identification plate shall be permanently mounted to the exterior of the building at a minimum of eight (8) feet above grade directly in
line with the exhaust vent terminal for the horizontally vented gas fueled heating appliance or equipment. The sign shall read, in print no less the one-half
inch (1/2”) in size, “GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS”.
INSPECTION
The state or local gas inspector of the side wall horizontally vented gas fueled equipment shall not approve the installation unless, upon inspection, the
inspector observes carbon monoxide detectors and signage installed in accordance with the provisions of 248 CMR 5.08 (2) (a) 1 through 4.
EXEMPTIONS
The following equipment is exempt from 248 CMR 5.08 (2) (a) 1 through 4:The equipment listed in Chapter 10 entitled “Equipment Not Required To Be
Vented” in the most current edition of NFPA 54 as adopted by the Board; and Product Approved side wall horizontally vented gas fueled equipment in-
stalled in a room or structure separate from the dwelling, building or structure used in whole or in part for residential purposes.
MANUFACTURER REQUIREMENTS - GAS EQUIPMENT VENTING SYSTEM PROVIDED
When the manufacturer of Product Approved side wall horizontally vented gas equipment provides a venting system design or ven ting system components with the equipment, the instructions provided by the manufacturer for installation of the equipment and the venting system shall include:
Detailed instructions for the installation of the venting system design or the venting system components; and
A complete parts list for the venting system design or venting system.
MANUFACTURER REQUIREMENTS - GAS EQUIPMENT VENTING SYSTEM NOT PROVIDED

Figure 2
A) DETERMINE LOCATION. Figure 3A.
1. Determine the exact position of your fireplace.
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 rigid pipe chimney
systems. 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 rooms. 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.
CAUTION - COLD AIR TRANSFER AREA. The surrounding outside
walls must be insulated to prevent cold air from entering the room.

FROM FURNITURE AND DRAPERIES.
Figure 3A
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 desired. The measurement is to the
TOP of the pipe. Please refer to pages #8-12 of this installation manual for requirements & restrictions.
Figure 3B
PAGE 6
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.
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.
Figure 3C
C) REMOVE GLASS ASSEMBLIES. See Figure 4.
Front Glass:
1. Locate the spring-loaded latch handles securing the center glass assembly.
2. Pull the handles out, then down to release the glass assembly.
3. Pull the bottom of the glass assembly out and lift up off the tabs (A) at the top.
4. Set aside where it will not be broken.
Side Glass:
1. Loosen and remove the (2) nuts securing each side glass assembly.
2. Pull the bottom of the glass assembly out and lift up off the tabs (at the top). Set aside.
3. Repeat steps #1 & #2 for remaining side glass assembly.
