INTRODUCTION

The Fireplace models covered in this manual are Direct-Vent sealed combustion vented gas fireplace heaters designed for residential application. Direct-Vent appliances operate with the combustion chamber completely isolated from the inside atmosphere. All air for combustion is brought in from the outside and exhaust gases are vented through the same direct vent, vent system.

These appliances feature a comfort control valve which allows remote control of temperature, fan and flame appearance. These appliances also use a spark ignitor (piezo) that allows the appliance's pilot gas to be lit without the use of matches. This system provides continued service in the event of a power outage.

The external electrical power (120v) is required to operate the provided circulating blower.

These appliances comply with National Safety Standards and are tested and listed by OmniTest Laboratories (Report No. 116-F-02-5) to ANSI Z21.88-2002 (in Canada, CSA-2.33-2002), and CAN/CGA-2.17-M91 in both USA and Canada, as vented gas fireplace heaters.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.

Step 6. ON the initial use of a transmitter, a

recognition operation is required between the receiver/valve and transmitter. Change the switch from LOCAL to REMOTE. Press the fan or flame button on the transmitter within 30 seconds. The LED will blink indicating the transmitter will now work with the receiver/valve. If the switch continues in the REMOTE position, the transmitter will now control the main valve, flame modulation level and fan control.

Step 7. If the manual switch is in the LOCAL position, the valve will be at the highest fixed pressure setting. The transmitter will control the fan only.

Shut Off Procedure

If the manual switch is in the REMOTE position, the transmitter can shut off the main burner and fan. However, the control is still on and a command from the transmitter can turn

the main burner or fan.

To shut off the system, turn the pilotstat knob clockwise to the OFF position. This action closes the main gas and safety valves. The transmitter now cannot turn on the main burner or fan.
