system by closing its individual manual shut-off valve
during any pressure equal to or less than 1/2 psig
(3.45kPa).
The heater and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.45kPa).
Fan Kit
115 volt, 60 Hz. 56w (Model FK24)
NOTE: The LHERDV20 and LHERDV30 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.
4. Wait until the unit has warmed up sufficiently to
activate the temperature sensor, approx. 5-10
minutes.

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.
