There are two (2) blower accessory options for
use in the vent-free fireboxes. Blower acces-
sory models are BK and BK3. Model BK is a
rotary squirrel cage type blower with magnetic
attachment and variable speed control. The
BK3 is a triple fan blower system with an on/
off rocker switch.
The blower must be installed by removing the
lower face panel and placing blower into its
proper mounting position.
Decide which way you intend to gain access
into the bottom rear of the firebox to install
the blower accessory. The lower front panel
can be removed easily by snapping out the
front with a flat blade screwdriver. Use cau-
tion not to scratch any surfaces. Models with
louvered front panels can also be removed by
inserting fingertips between slots and gently
pulling out. DO NOT FORCE. The panels are
actually held in place by means of a retention
dimple embossed on the edge of removable
panels.
warninG: if there is a duplex
electrical outlet installed in the
right side of the bottom of the
fireplace base area (see figure
10), be sure that the electrical
power to the outlet is turned off
before proceeding with blower
installation. failure to do this
may result in serious injury.
