HMFATV INTRODUCTION
The HMFATV Television Kit is designed to automate the
operation of the HMFA Forced Air Blower, in order to protect
a wall-mounted television from heat damage while the
fireplace is in use. During normal operation the blower is
turned on and off by a snap-disc inside the firebox. In the
case of a power outage or blower failure, the fireplace will
be deactivated by a wall-mounted limit switch in order to
protect the television. The rheostat control included in the
HMFA Forced Air Blower is not utilized.
