WSK-MLT MULTIFUNCTION WALL SWITCH
- INSTALLATION AND OPERATING INSTRUCTIONS -
Figure 1.
Introduction
The WSK-MLT multifunctional wall switch is designed to 
control fl ame height, blower speed, and auxiliary functions 
on your gas fireplace. For models equipped with the 
Intellifi re system (IPI), the cold climate function can control 
the pilot fl ame as well. The wall switch is equipped with 
thermostat functions which can automatically control the 
temperature in the room in which it is installed. The wall 
switch interfaces with both intermittent and standing pilot 
systems. An auxiliary function provides 110-120 VAC 
source for added features the fi replace may have installed.  
Electrical ratings for the control box are 110 VAC, 60 Hz, 
and is required for operation of this device.
Installation precautions
This remote is tested and safe when installed in accordance 
with this installation manual. It is your responsibility to 
read all instructions before starting installation and to 
follow these instructions carefully during installation. Do 
not install any components that may be damaged. Do not 
modify,  disassemble, or substitute any of the components 
included with this kit. Installation of this unit must be done 
by a qualifi ed service technician.  
Placement of this wall switch may affect performance 
or accuracy of the automatic (thermostat) control.  An 
assessment of the space should be done prior to installation 
for optimal performance. See the installation instructions 
section I for recommendations.
1.0  Installation instructions
1.1  Determine location
Determine the location for the wall switch. The chosen 
location should provide an accessible location in the 
same space as the gas fi replace. Never place this unit in 
a separate room. The control wire supplied with this switch 
is 33 ft (10M) in length. The distance from the fi replace to 
the switch may be lengthened provided that the wire used 
never exceeds 50 ft, and that the distance from the fi replace 
to the switch never exceeds 30 ft.
The switch should be mounted into a listed electrical junc-
tion box. The junction box should be dedicated to this wall 
switch. Never install this wall switch into a junction box 
that is shared with other electrical service or devices. If 
possible, install this unit on an interior wall of the residence 
at a recommended height of 5 ft from the fl ooring. Should 
the switch be installed on an exterior wall, be certain wall 
insulation is kept intact and not damaged or dislodged dur-
ing the installation of the electrical junction box. 
For exterior wall installations, it is recommended that the 
junction box be sealed with caulking material. This will 
minimize heat loss through this location and improve the 
accuracy of the automatic (thermostat) operation.  
WARNING
Shock Hazard
Do not provide any power to this unit until all 
wiring is completed. Failure to do so may destroy 
parts of this device and render it unusable, and 
may lead to possible electrical shock.
Fire Hazard
Modification of any parts or installation of 
damaged components will void the warranty, 
and you may possibly cause a fi re hazard.
NOTE: The electrical junction box provided with the fi replace 
must be wired with 110 VAC before installing this kit. See 
owners manual for details.
All wiring should be done by a qualifi ed electrician and 
shall be in compliance with local codes and with the 
National Electric Code ANSI/NFGA No. 70- current (in the 
United States), or with the current CSA C22.1 CANADIAN 
ELECTRIC CODE (in Canada).
