WSK-MLT MULTIFUNCTION WALL SWITCH

- INSTALLATION AND OPERATING INSTRUCTIONS -

Introduction

The WSK-MLT multifunctional wall switch is designed to control flame height, blower speed, and auxiliary functions on your gas fireplace. For models equipped with the Intellifire system (IPI), the cold climate function can control the pilot flame 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 fireplace 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.

1.0 Installation instructions

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.

NOTE: The electrical junction box provided with the fireplace must be wired with 110 VAC before installing this kit. See owners manual for details.

All wiring should be done by a qualified 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).

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 fire hazard.

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 fireplace. 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 fireplace to the switch may be lengthened provided that the wire used never exceeds 50 ft, and that the distance from the fireplace 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 flooring. 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.
