INTRODUCTION
The Fireplace models covered in this manual
are Direct-Vent sealed combustion gas fireplace
heaters designed for residential application.
Direct-Vent appliances operate with the com-
bustion 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.
Electronic Models -
Electronic models have a fixed rate gas valve.
The BTU Input for electronic models is shown
in Table 2:

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. Do not use any
other fuels. The use of other fuels, or combi-
nation 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 - BTU Input
Millivolt models come standard with the manu-
ally-modulated gas valve; flame appearance and
heat output can be controlled at the gas valve.
The BTU Input for millivolt models is shown
in Table 1:
The Millivolt appliances have a millivolt gas
control valve with piezo ignition system provides
safe, efficient operation. If any optional acces-
sories which require electrical power are being
installed, the electrical power must be provided
at the time of appliance installation.
The Electronic appliances have an electronic
intermittent pilot system provides safe, efficient
operation. External electrical power is required
to operate these appliances.
These appliances comply with National Safety
Standards and are tested and listed by Omni-Test
Laboratories (Report No. 116-F-29-5) to ANSI
Z21.88 (in Canada, CSA-2.33), and CAN/CGA-
2.17-M91 in both USA and Canada, as vented
gas fireplace heaters.
The Installation must conform to local codes
or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1/NFPA
54-latest edition, or the Natural Gas and
Propane Installation Code, CSA B149.1-latest
edition. The appliance, when installed, must
be electrically grounded in accordance with
local codes or, in the absence of local codes,
the latest edition of the National Electrical Code,
ANSI/NFPA 70, or the Canadian Electrical Code,
CSA C22.1 - latest editions.
GENERAL INFORMATION
Note: Installation and repair should be per-
formed by a qualified service person. The
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,
bedding material, etc.
It is imperative that the control compartment,
burners and circulating air passage ways of
appliance be kept clean.
