Optional Accessories
Fan Kit
The FK12 fan kit is available for use on the NVBC36
and NBVC42 model appliances only.
Auxiliary fan systems increase the efficiency of the cir-
culation of the heating air. The FK12 fan assembly is a
fixed speed fan system and does not allow for variable
speed control.
Installation
Remove the 2 ceramic fiber refractory panels by care-
fully lifting them out of the fireplace. Next, remove the
access panel by pulling it up and out from the side
edge of the panel. Use caution — the panel edges may
be sharp.
Center the fan assembly over the mounting location
and secure it with the Velcro
®
strips at the back of the
fireplace.
Insert the plug into the receptacle (EB1) located against
the lower right side wall of the fireplace.
Caution:
Be sure that no wires are pinched.
Prior to reinstalling the access panel and the hearth
brick, it is advisable to operate the wall switch on and
off to assure fan operation. If the fan does not operate
and you are assured that 115 VAC power is present at
the receptacle, contact your Dealer.
Reinstall the access panel and hearth brick by reversing
Step 1.
WARNING: Never contact blower wheels during
operation.
Speed Control
The SCVS variable speed control is available to allow
speed adjustment of the fan.

The EB-1 electrical junction box is available for use with
the fan kits. The EB-1 is standard on the electronic igni-
tion models.

The Model AK-MST Outside Air Kit is designed to bring
additional combustion air directly from the outside to the

Installing the TVD6/7 Thermal Vent Damper reduces

ing and closing automatically.
Attach the thermal vent damper to the combustion
dome with 2 screws. Be sure the tab points down. (Fig.

Start the appliance and operate it for approximately 5
minutes. Turn the unit off and check if the vent damper
is in the open position (blades down from the horizontal
position). If the damper has not opened, check installa-
tion.
