NA SERIES INSTALLATION INSTRUCTIONS
Note:

the face of the fireplace below the level of the front
standoffs. A noncombustible material such as USG
MICORE CV230 Mineral Fiber Board, or USG
DUROCK Cement Board is recommended for this
purpose.
Figure 16 - Air Clearance Around Gas Line
16. Completion of the Enclosure
Complete the fireplace enclosure, allowing space for
outside air ducts and gas piping if desired. Electrical
wiring should not come in contact with the fireplace.
A
minimum clearance of ½ must be maintained
between the fireplace sides and the enclosure as
well as the fireplace back and the enclosure.
See
pages 10-12 for framing details.
CAUTION:
When using a gas log set, the fireplace damper
must be set in the fully open position. This en-
sures proper venting of combustion products.
WARNING!
This fireplace was not tested by the fireplace manu-
facturer for use with an unvented gas log heater.
To reduce risk of injury, do not install an unvented
gas log heater in this fireplace unless it has been
specifically tested and listed by Underwriters Labo-
ratories Inc. for use in this specific model fireplace.
Unless the unvented gas log heater is tested and
listed for use in this factory built fireplace, a fire
hazard may be created that can result in a structure
fire.
17. Gas Log/Lighter Provisions
Knockouts are provided on both sides of the fireplace
to allow for connection of a certified gas log lighter or
a decorative gas appliance with a maximum input of
100,000 BTU/hour, incorporating an automatic gas
shut-off device and complying with the
Standard for
Decorative Gas Appliances for Installation in
Vented Fireplaces, ANSI Z21.60
. The decorative gas
appliance should be installed in accordance with the
National Fuel Gas Code, ANSI Z223.1-1980
.
CLEARANCES!
A minimum ½ air clearance must be maintained at
the back and sides of the fireplace assembly.
Chimney sections at any level require a 2 minimum
air space clearance between the framing and chim-
ney section.
WARNING!
Disconnect power before stripping or joining any
supply wires. Only persons qualified for making
electrical installations (electricians) as recognized
by local or national governmental bodies should
attempt to make the incoming supply wire connec-
tions.
Edges are sharp! Hand protection is recommended.
Recheck all fasteners before leaving the job.
Note:
A BC10 motor speed control kit is available for
use with this fan kit. Refer to the instructions packed with
it for proper installation. If a speed control option is
desired, it is recommended that you use the BC10 kit to
ensure proper function.
The side refractories are designed to allow ½ iron pipe
to pass through. Use a noncombustible sealant to seal
any opening between the gas pipe and refractory on
the inside. Repack the insulation removed to seal
around the gas pipe where it exits the side of the
fireplace. A minimum 1½ air clearance must be
provided around the ½ iron pipe for a minimum of 4
inches beyond the fireplace. See Figure 16.
