system by closing its individual manual shut-off valve
during any pressure equal to or less than 1/2 psig
(3.45kPa).

Fan Kit
115 volt, 60 Hz. 56w (Model FK24)
NOTE: The LHER20 and LHER30 are not designed for
a fan kit.
The fan kit includes the following: fan, temperature
sensor, speed control and a 6 ft. cord. The following
explains how to start and set the fan for automatic
operation.
1. Plug in the electrical cord.
2. Start gas fire - see lighting procedures.
3. Turn on fan speed control.

speed. The fan will now automatically come on every
time the fireplace is in operation. Should the fan not
be needed simply turn off the speed control.
