GENERAL INFORMATION
Note: Installation and repair should be per-

appliance should be inspected annually by a
qualified professional service technician. More
frequent inspections and cleanings may be
required due to excessive lint from carpeting,

d'installation et d'utilisation qui accompagnent
l'appareil.
Provide adequate clearances around air open-
ings and adequate accessibility clearance for
service and proper operation. Never obstruct
the front openings of the appliance.
These appliances are designed to operate on
natural or propane gas only. The use of other
fuels or combination of fuels will degrade
the performance of this system and may be
dangerous.
These fireplaces are designed as supplemen-
tal heaters. Therefore, it is advisable to have
an alternate heat source when installed in a
dwelling.
Millivolt Models - The millivolt appliances are
manually controlled and feature a spark igniter
(piezo) that allows the appliance's pilot gas to
be lit without the use of matches or batteries.
This system provides continued service in the
event of a power outage.
Millivolt models come standard with a manu-
ally-modulated gas valve; flame appearance and
heat output can be controlled at the gas valve.
The BTU Input for these appliances is shown
in Tables 1 & 2.
The Millivolt appliances have a millivolt gas
control valve with piezo ignition system which
provides safe, efficient operation. If any optional
accessories that will require electrical power
are to be installed, the electrical power must be
provided at the time of appliance installation.
The
Electronic appliances have an electronic
intermittent pilot ignition system which provides
safe, efficient operation. External electrical pow-
er is required to operate these appliances.
