1. LOCATION AND SPACE REQUIREMENTS.
This appliance may be installed along a wall, across a corner or in an exterior chase. DO NOT install B-Vent
Gas Appliances in strong negative air locations, such as a basement or a public facility. This fireplace
uses room air for normal operation and could have problems establishing a positive draft in negative
air locations. In lieu, we recommend a direct vent appliance.The G141 Series may be installed at a
height level with the floor, or it can be raised up from the floor to enhance its visual impact. Figure 1 illustrates
a variety of ways the fireplace may be located in a room. These fireplaces are also certified for installation in
a bedroom or bed/sitting room in the U.S. and Canada. (Bedroom installations in Canada require the addition
of non-operable doors.)
2. CLEARANCES.
The following clearances to combustibles must be maintained: Minimum clearances to the top standoffs of the
fireplace - 0, floor - 0, back - 1, sides - 1, face of the fireplace to ceiling - 30. Minimum clearances to venting
are as follows: Horizontal run sections require a 3 minimum air space on the top and a 1 minimum air space
on the sides and bottom of the vent section. Venting that is vertical requires a 1 minimum air space completely
around the vent section.

C. FRAMING
1. FRAMING THE FIREPLACE.
The G141 Series Gas Appliance will fit a framed opening of 17 deep x 40-1/4 wide x 36-3/4 tall.
Figure 2 shows a typical framing of this appliance assuming combustible materials are used. All required
clearances to combustibles around the fireplace must be adhered to. A 1 air space clearance must be
maintained at the back and sides of the firebox assembly. Any framing on top of the fireplace must be above
the top standoffs. Vent sections for a horizontal run require a 3 minimum air space clearance on top and a 1
minimum air space clearance on the sides and bottom. Vertical vent sections require a 1 minimum air space
clearance completely around the vent section.
Note: If a hand held Remote Control (RC4 or RC5)

This fireplace may be placed on either a combustible
or noncombustible continuous, flat surface. If the
fireplace is installed on combustible flooring other than
wood, a metal or wood panel needs to be installed
underneath the appliance extending its full width and
depth. Slide the fireplace into position and level the
fireplace from side-to-side and front-to-back. Shim with
noncombustible material, such as sheet metal, as
necessary.
Secure the fireplace by bending out the nailing flanges
located on each side of the fireplace and nailing the
fireplace to the framing. See Figure 4.

D. SETTING THE FIREPLACE
Figure 4 - Nailing Flanges
G141 SERIES B-VENT GAS APPLIANCE
E. VENTING
1. TERMINATION.
Common venting of this gas appliance with other
gas appliances is not allowed.
This fireplace requires the use of a 5 B-vent pipe
for operation and must be terminated above the
roof line. Never downsize pipe. Follow all B-vent
requirements and installation instructions.
The minimum height of vent installation must be 9
from the top or 12 from the base of the appliance.
Horizontal run must never exceed 20% of the height
of the vent system as shown in Figure 5.
The Figures 5 and 6 show the maximum distances
from the base of the fireplace, as well as the
minimum air space clearances that must be
maintained during termination of this appliance.
Maximum straight unsupported rise - 25 feet;
maximum horizontal unsupported run - 3 feet; air
space clearances around vertical rise - 1 on all
sides; air space clearances around the horizontal
run - 3 on top and 1 on sides and bottom; maximum
height - 40 from the base of the fireplace.
Figure 5 - Venting Off The Top of Appliance
Note: The horizontal run of vent must have a
1/4 rise for every 1 ft. of run towards the termination. Never allow the vent to run downward.
This could cause high temperatures and may
present the possibility of a fire.
Minimum clearances are per vent

G141 SERIES B-VENT GAS APPLIANCE
2. ASSEMBLY.
a. Assembling Vent Sections. Attach a straight
vent section to the top of the fireplace. Elbows
directly off the top of the fireplace are not
allowed. This may cause the fireplace to
operate ineffectively. Secure the attached vent
section to the appliance with the three screws
supplied. Use only B-vent sections.
b. Using Elbows. Elbows 45 degrees and greater
from the vertical shall be considered horizontal
and therefore adopt horizontal run limitations.
See Figure 7.
c. Penetrating the Ceiling. Mark and cut out
an opening in the ceiling for the firestop spacer.
Frame the opening with the same size lumber
used in the ceiling joists.
d. Installing the Firestop Spacers. Firestop
spacers must be used whenever the venting
penetrates a ceiling/floor area.
In all situations, firestop spacers are to be
nailed to the ceiling joists from the bottom or
appliance side, EXCEPT when the space above
is an insulated ceiling or attic space. In this
situation, the firestop spacer must be nailed
from the top side to prevent loose insulation
from falling into the required one inch air space
around the vent system.
Install the firestop spacer by positioning and
nailing the four sides of the firestop spacer to
the joists using a minimum of three nails per
side.
Note: Be sure to provide intermediate support
for the vent during construction and check to
be sure inadvertent loading has not dislodged
the vent from the appliance or any vent joint.
Figure 7 - Using Elbows
WARNING!
When vent sections exceeding 3 feet
in length are installed between an offset and return, structural support must
be provided to reduce off-center loading and prevent vent sections from
separating at the vent joints. Follow all
B-vent manufacturer guidelines.
e. Securing Vent System. Continue assembling
the vent sections up through the firestop
spacers as needed. Vent sections must be
locked into position. Elbows and chimney
stabilizers have straps for securing these parts
to joists or rafters.
f. Marking the Exit Point in the Roof. Locate
the point where the venting will exit the roof by
plumbing down to the center of the vent system.
Drive a nail up through the roof to mark the
center. See Figure 8.
g. Cutting Out the Hole in the Roof. Measure
to either side of the nail and mark that 7 x 7
opening required (must meet minimum
clearances per venting requirements). This is
measured on the horizontal; actual length may
32921 Rev A 8 10-00
Figure 8 - Exiting Through the Roof
G141 SERIES B-VENT GAS APPLIANCE
be larger depending on the pitch of the roof.
Cut out and frame the opening. See the Uniform
Building Code for Roof Framing details. A one
inch minimum air space clearance must be
maintained between the vent section and the
roof.
h. Install Roof Flashing or Site-Produced
Chase Top. Position a roof flashing or a site-
produced chase to and secure into place.
i. Assembling Vent Sections. Continue to add
vent sections through the roof opening,
maintaining a minimum of one inch air space
clearance.
j. Termination Cap. Major building codes
specify a minimum termination height above
the roof top depending on the roof pitch. See
Figures 9 and 10.
These termination heights are necessary in the
interest of safety and do not guarantee proper
operation. Trees, buildings, adjoining roof lines,
adverse wind conditions, etc. may create a
need for a taller roof termination should down
drafting occur.
To install the termination cap, slide the cap
vent sections into the vent pipe. Secure the
cap using the screws provided.
k. Checking the Vent System. Periodically the
venting system should be tested to assure
proper operation. This can be done with a
match while the fireplace is operating.
Hold a lighted match at the top edge of the
firebox opening. If the flames and smoke remain
upright, ventilation is acceptable. If the flames
and smoke are drawn into the firebox, this
means ventilation is good. If the flames and
smoke are forced away from the firebox, this
may indicate a ventilation blockage or down
draft resulting in gas spillage into your home. If
this occurs, turn off the fireplace and do not
burn it until it has been inspected by a qualified
service person.
If you have installed optional doors, close the
doors and conduct the test following the same
instructions above. See Figure 11.
