NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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 which require electrical
power are being installed, the electrical power
must be provided at the time of appliance in-
stallation.
The Electronic appliances have a battery backed-
up electronic intermittent pilot system. No
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, Inc. (Report No. 116-F-39C-5)
to ANSI ZZ21.88 (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, CAN/CSA B149.1-latest edi-
tion. 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.
The vent termination is hot while in opera-
tion and for a period of time following the
use of the fireplace. To prevent contact
with hot surfaces, we recommend the use
of a termination guard. See Page 21 for
ordering information.
These fireplaces are designed as supple-
mental heaters. Therefore, it is advisable
to have an alternate primary heat source
when installed in a dwelling.
These appliances must not be connected to
a chimney or flue serving a separate solid
fuel burning appliance.
