ly 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”.
1.3.4 Inspection
The state or local gas inspector of the side wall horizontally vented gas fueled equipment shall not approve the installation unless, upon inspec-
tion ,the inspector observes carbon monoxide detectors and signage installed in accordance with the provisions of 248 CMR 5.08 (2) (a) 1 through

WARNING
Top stand-off brackets must be formed and attached prior to positioning fireplace into framed opening.
The top stand-offs provide the 10 in. (254 mm) minimum clearance to the header. Use only non-combustible material in this area for
entire width of fireplace. Do not use wood, sheetrock, etc., in this zone.
NOTE: Top stand-off brackets and stand-off heat shields
are attached to fireplace top in a flat state for shipping.
See Illustration 1 in Figure 3.1, Stand-Off Assembly and
Installation.
1. Remove and save (4) screws securing top stand-off heat
shield and stand-off brackets.
2. Form each top stand-off bracket by bending at
perforations, as shown in Illustration 2.
3. Align the holes in the formed top stand-offs with the holes
in the fireplace top. Secure with the (4) screws previously
removed along with (4) screws located on top of the
fireplace.
4. Form stand-off heat shields as shown in Illustration 4.
The flange on the stand-off heat shields will face up and
to the back of fireplace.
5. Align the holes in the formed stand-off heat shields with
the holes in the top stand-off brackets. Secure with (8)
screws provided in the fireplace components packet.

3.0 FRAMING AND CLEARANCES
3.2 Stand-off Assembly and Installation
 This fireplace must be installed on a level surface capable of supporting the fireplace and venting.
 Determine the exact position of your fireplace, including hearth height, width, and depth. If possible, place the fireplace in such
a manner that the vent termination will be placed between two studs, thus eliminating the need for additional framing.
 This fireplace may be installed in a bedroom.
 Due to high temperatures, the appliance should be located out of traffic and away from furniture and draperies.
 Please be aware of the large amount of heat this fireplace will produce when determining a location.
WARNING
Install the fireplace on a hard metal or wood surface that extends the full width and depth of fireplace.
Above floor level installations: A solid, continuous platform must be constructed below the appliance.
MINIMUM PLATFORM SIZE: 40-3/4 in. (1035 mm) wide x 17 in. (431 mm) deep.
FIRE HAZARD
Do NOT install directly on carpeting, vinyl, or any combustible material other than wood.

CAUTION
Never permanently remove these assemblies from the fireplace—they must be secured regardless of finish material used.
1. Remove (4) nailing flanges from the right and left side of the fireplace. See Figure 3.2, Back View of Nailing Flanges.
2. Align nailing flange with holes on outside corners of fireplace, with the stand-off flanges on the nailing flanges facing away
from the fireplace See Figure 3.2.
3. Secure the nailing flanges to the fireplace with screws (provided) through the slots in nailing flanges.
4. Bend perforation on nailing flange until parallel with fireplace face. Do not bend toward fireplace face.
5. Position framing stud against the small stand-off (located on backside of nailing flange). Secure with nails or screws. See
Figure 3.3, Front View of Set Nailing Flange
 When installed, the nailing flanges provide the minimum 1/4 in. (6 mm) clearance from the sides of the fireplace to
framing. See Figure 3.4, Top View of Nailing Flange Installed.

3.5.1 Wall Enclosure Rough Opening
 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 top of fireplace to support the added weight.
 Build the hearth to desired size and height. If a hearth extension is desired, combustible material may be used.
 Consider the height of hearth finish material (stone, brick, etc.) when building a fireplace platform. The bottom of the fireplace
must be level with finished hearth to allow for proper fitment of the safety barrier, except model #B41-BSF, a 1-1/4 in. (32 mm)
clearance below the fireplace for proper fitment. Refer to Table 5.2 on page 14.

*
Non-Combustible Materials
ONLY in this zone.
WARNING
Provide adequate clearances around air openings into the combustion chamber.
Do not obstruct upper and lower grill openings. Room air enters through the lower passage, is then heated, and exists through upper
passage. Blocking these passages may result in overheating, creating a potentially hazardous situation.
5.0 FACING AND FINISHING
Table 5.1, Non-Combustible Zone
Rigid Pipe: 1-1/2 in. (38mm) above the elbow for the entire width and depth (behind header) of the fireplace.
#700-1 Series Flexible Venting: 1 in. (25mm) above the elbow for the entire width and depth (behind header) of the fireplace.
 Provide adequate clearance in front of the fireplace to remove safety barrier, to operate lower grill, to access components, to
install gas line, and other components.
 Non-combustible material may be applied over, but not attached, to the fireplace face. This will prevent non-combustible
material from falling off the fireplace face due to heat expansion.
 Do not obstruct the flow of ventilation air.
 Refer to Table 5.2, Safety Barrier Fit and Mounting Clearances, on page 14 for accessibility clearances. Refer to
Figures 5.2 - 5.5 on pages 14 through 16 for safety barrier models and dimensions.
5.1 Mantel Requirements
Figure 5.1, Mantel Projections, Trim Requirements, and Non-Combustible Zone
NON-COMBUSTIBLE ZONE: No materials are allowed above the fireplace within the shaded
area for the entire width and depth of the fireplace. This air space must remain open.
* This 3/4 in. (19 mm) deep fireplace facing top trim (top facing) requires a 10 in. (254 mm)
clearance from the fireplace top.

ATTENTION
In the USA: The appliance may be installed at higher altitudes. Please refer to your American Gas Association guidelines
which state: the sea level rated input of Gas Designed Appliances installed at elevations above 2,000 ft. (610 m) is to be reduced
4% for each 1,000 ft. (305 m) above sea level. Refer also to National Fuel Gas Code, ANSI Z223.1 / NFPA 54, local authorities, or
codes which have jurisdiction in your area regarding the de-rate guidelines.
In Canada: When the appliance is installed at elevations above 4,500 ft. (1,372 m), the certified high altitude rating shall
be reduced at the rate of 4% for each additional 1,000 ft. (305 m). Refer also to CSA-B149.1 Natural Gas and Propane Installation
Code, Local authorities, or codes which have jurisdiction in your area regarding the de-rate guidelines.
This fireplace is manufactured for use with Natural Gas. Follow the instructions included with the conversion kit if converting to LP
gas. (Sold separately)
ATTENTION
The conversion shall be carried out in accordance with the requirements of the provincial authorities having jurisdiction and in
accordance with the requirements of the ANSI Z223.1 installation code.
CAUTION
Installation of the gas line must only be done by a qualified person in accordance with local building codes, if any. If not, follow ANSI
223.1.
Commonwealth of Massachusetts: Installation must be done by a licensed plumber or gas fitter.
NOTE
A listed (and Commonwealth of Massachusetts approved) 1/2 in. (13 mm) tee handle manual shut-off valve and flexible gas connector
are to be connected to the 1/2 in. (13 mm) control valve inlet. If substituting for these components, please consult local codes for
compliance.
This fireplace is equipped with a 3/8” (10 mm) x 18” (457 mm) long flexible gas connector and manual shut-off valve. The gas line should
be run to the point of connection where the shut-off valve and flexible gas line will connect.
The appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of
that system at pressures in excess of ½ psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure
testing of the gas line at test pressures equal to or less than ½ psi (3.5 kPa).
For high altitude installations, consult the local gas distributor or the authority having jurisdiction for proper rating methods.
IMPORTANT
The efficiency rating of this appliance is a product of thermal efficiency rating determined under continuous operating conditions and
was determined independently of any installed system.
