GBR Series B-Vent Gas Fireplace
Description
GBR Series are radiant natural draft appliances and use a 4" Bvent system. Do not burn wood or other materials in these appliances. Each model is available with standing pilot or electronic
ignition for use with Natural or Propane gas units.
Report to your dealer any parts damaged in shipment.
Adequate combustion and ventilation air must be provided. The
flow of combustion and ventilation air MUST NOT be obstruct
ed.
Provide adequate clearances around the air opening into the
combustion chamber; and adequate accessibility clearance for
servicing and proper operation. NEVER obstruct the front opening of the appliance.
The 4" vent system MUST connect to the appliance and ter
minate out-of-doors in a vertical position and terminate with a
B-vent cap.
This appliance must not be connected to a chimney flue servicing a separate solid-fuel burning appliance.
A draft hood is an integral part of the appliance.
GBR36
Certified to
ANSI Z21.50b-2002 / CSA 2.22b-2002
Vented Gas Fireplace
Proposition 65 Warning: Fuels used in gas, wood-
burning or oil fired appliances, and the products of
combustion of such fuels, contain chemicals known to
the State of California to cause cancer, birth defects
and other reproductive harm.
California Health & Safety Code Sec. 25249.6
IMPORTANT:
PLEASE READ THE FOLLOWING CAREFULLY
Remove any plastic from trim parts before turning the
fireplace “ON”.
It is normal for fireplaces fabricated of steel to give off
some expansion and/or contraction noises during the
start up or cool down cycle. Similar noises are found
with your furnace heat exchanger or car engine.
It is not unusual for your gas fireplace to give off some
odor the first time it is burned. This is due to the curing
of the paint and any undetected oil used in the manufacturing process.
Please ensure that your room is well ventilated.
Open all windows.
It is recommended that you burn your fireplace for at
least ten (10) continuous hours the first time you use it.
If the optional fan kit has been installed, place the fan
switch in the “OFF” position during this time.

Mantels
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths refer to
Figures 2a and 2b.
Noncombustible mantels and legs may be installed at
any height and width around the appliance.
When using paint or lacquer to finish the
mantel, such paint or lacquer must be heat
resistant to prevent discoloration.
NOTE: Place header on end to maintain proper
clearance to 'B' vent.

Insulating for Cold Climates
When an appliance is installed in a chase or an outside
wall, the enclosure should be insulated like any other
wall of the home. Insulation should be installed under
the appliance and on the inside of the exterior walls.
In a chase, it is a good idea to install a firestop at the
first ceiling level above the appliance. Also, install insu
lation on the side walls. Insulation may then be placed
above the ceiling to assure the space around the appliance is protected. Refer to Page 7, Figure 4.
-
5
GBR Series B-Vent Gas Fireplace
Be sure to always maintain the proper one
(1) inch distance to combustibles around
B-vent pipe sections.
NOTE: Insulating for cold climates is strictly a recom-
mendation and not a requirement.
Framing and Finishing
Check appliance to make sure it is levelled
and properly positioned.
The appliance should only be mounted on the
following surfaces:
• A flat combustible (burnable) surface.
• A raised wooden platform.
• A concrete block or other solid object
placed beneath each of the four corners
of the appliance.
To mount the appliance:
1. Choose unit location.
2. Four (4) nailing flanges are supplied with the fire
place (found on the fireplace hearth). To level the
box and secure it firmly in place, remove the nailing
flanges from the hearth and install at the sides of the
fireplace as shown in Figure 3.
-
Finishing
CAUTION: All joints between the finished
wall and the appliance surround (top and
sides) may be sealed only with non-combustible material. Only noncombustible
material can be applied as facing to the
appliance surround (the black painted
face).
When finishing the appliance, never obstruct or modify
the air inlet/outlet grilles in any manner.
Finish the wall with the material of your choice. Refer to
Figures 2a and 2b for specific clearances when installing a combustible mantel or other combustible projection.

Gas Line Installation
This appliance must be isolated from the gas supply
piping system by closing its individual manual shut off
valve during any pressure equal to or less than 1/2 psig
(3.45 kPa).
The appliance and its individual shutoff valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45 kPa).
If gas piping from the source to the appliance location
has not been accomplished, install the required pipe.
Consult local plumbing code to assure proper pipe size.
7412955
FP625
The gas pipeline can be brought in through the right
side of the appliance. An access hole is provided to
allow for the gas pipe installation and testing of any gas
connection. It is most convenient to bring the gas line
in from the right side, as this allows fan installation or
removal without disconnecting the gas line.
NOTE: The gas line connection can be made with 3/8"
copper tubing, 1/2" rigid pipe or an approved flex connector, then reduced to 3/8" to the appliance. Because
some municipalities have some additional local codes,
it is always best to consult your local authority.

U.S.: Consult the current National Fuel Gas Code,

Canada: CSA - B149.1 installation code.
Always check for gas leaks with a mild
soap and water solution. Apply water/soap
solution with brush only - do not over apply. NEVER test with an open flame.
The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8" test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union so that gas line can
be easily disconnected for burner or fan servicing.
See gas specification for pressure details and ratings.
NOTE: If flex connector is used, it must be kept inside
of the appliance. (Fig. 5)

EB-1 Electrical Box
The fireplace, when installed, must be electrically connected and grounded in accordance with local codes or, in the absence
of local codes, with the current CSA C22.1
Canadian Electrical Code.
For USA installations, follow local codes
and the National Electrical Code, ANSI/
NFPA No. 70.
It is strongly suggested that the wiring of
the EB-1 electrical junction box be carried
out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commencing this procedure.
Once the fireplace is secured, complete wiring the fan
kit. Remove knockout in the center of the back of the
EB1 and install listed cable clamps. Feed electrical
wire through cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure cable
clamp to the wire.
Attach white wire from power source to one (1) wire of
receptacle and secure with a nut. Attach black wire from
power source to the other wire of the receptacle and
secure with a nut. Be sure nuts are tightened securely.
Secure the EB1 assembly to the inside of the electrical
box coverplate using two (2) screws. Attach the cover
to the face of the EB1 while being careful to position
excess wire completely within the EB1. Attach the coverplate to the fireplace. (Fig. 8)
Install the Venting System,
Flashing and Termination
See venting installation instructions provided by the BVent manufacturer.
Refer to Page 4, Figure 1 to locate chimney centerline
dimension from a combustible back wall.
• Minimum vertical chimney height — 12 feet (3.65m).
• Maximum vertical height — 40 feet (12m).
• Minimum height with two 90° elbows — 16 feet
(4.06m)
• Elbow requirements allow a maximum of two
90 degree elbows or four 45 degree elbows
per installation. (Two 45 degree elbows =
One 90 degree elbow.) See venting chart for
proper elbow offset runs. Use Figure 10 for GBR36
installations when not installing the GSKBB Single
Panel Glass Door. Use Figure 11 for GBR36 installations when installing the GSKBB Single Panel
Glass Door.
For firestop positioning, refer to Figure 9. Only one (1)
firestop required per frame. NOTE: A firestop is not
required at the roof.
