GENERAL INFORMATION

These See-Through Unvented Gas Log Room Heaters incorporate unitized ceramic fiber logs which glow realistically when the heater is operating.

These log heaters are either thermostatic (T-stat) or manually controlled. The control knob is set to the desired position, which maintains a continuous gas burning rate.

A spark ignition system (piezo) allows the gas pilot to be lit without the use of matches or batteries and permits operation of the heater during a power outage.

These heaters are fitted with a specially de- signed pilot utilizing an oxygen depletion sen- sor (ODS) which responds to the amount of oxygen available in the room and shuts the heater off before the oxygen level drops below 18%.

The pilot can be relit only when fresh air is available. Refer to the Combustion and Ventila- tion Air section.

WARNING: THIS APPLIANCE IS FOR IN- STALLATION IN A SOLID FUEL BURN- ING FIREPLACE WITH A WORKING FLUE OR AN APPROVED VENTLESS FIREBOX ENCLOSURE ONLY.
