GENERAL INFORMATION
The fireplace models covered in this manual
are direct-vent sealed combustion gas
fireplace heaters designed for residential
application. These direct-vent appliances
operate with the combustion chamber
completely isolated from the indoor
environment.
All air for combustion is brought in from
the outside and exhaust gases are vented
through the same direct-vent, co-axial
(intake/exhaust) vent system.
The Millivolt appliances have a millivolt gas
control valve with piezo ignition system. 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 are designed
to operate on natural or propane gas. An
electronic intermittent pilot ignition system
provides safe, efficient operation. External
electrical power is required to operate these
units. During a power outage the fireplace
may be operated using the battery backup.
These appliances comply with National
Safety Standards and are tested and listed
by OMNI-Test Laboratories, Inc. (Report
No. 116-F-13-4) to ANSI ZZ21.88-2009 (in
