This heater must be isolated from the gas supply piping 
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).

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.
4.  Wait until the unit has warmed up sufficiently to 

activate the temperature sensor, approx. 5-10 
minutes.

5.  Once fan starts, adjust speed control to desired fan 

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.

The appliance, when installed must be 
electrically connected and grounded in 
accordance with local codes or, in the ab-
sence of local codes, with the current CSA 
C22.1 Canadian Electrical Code.
U.S. Installations, follow local codes and the 
National Electrical Code, ANSI/NFPA No. 70.
Should this fan require servicing, the 
power supply must be disconnected.  For 
rewiring  of any replacement components 
refer to Figure 6.

1.  Turn off gas and electricity.
2.  Remove the front glass.
