GENERAL INFORMATION
These Unvented Gas Log Room Heaters incor-
porate unitized ceramic fiber logs which glow
realistically when the heater is operating.
The log sets covered in this document are
manually controlled heater rated units. These
units are equipped with either a standard manual
gas valve or a millivolt gas valve. The control
knob is set to the desired position, which main-
tains 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 Ven-
tilation Air section.
