LENNOX HEARTH PRODUCTS • SIGNATURE

INTRODUCTION

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.
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. In the event of a power outage,
four (4) AA batteries provide backup power
for appliance operation (excluding blower).
These appliances comply with National
Safety Standards and are tested and listed
by ETL/Intertek. (Report No. G100513653
PRT-001) 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. These appliances are listed by ETL/
Intertek for installation in bedrooms and
manufactured homes.
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 (In Canada,
the current CAN/CSA-B149.1 installation
code). The appliance, when installed,
must be electrically grounded and wired
in accordance with local codes or, in the
absence of local codes, with the National
Electrical Code, ANSI/NFPA 70—latest
edition, or the Canadian Electrical Code,
CSA C22.1—latest edition.
Provide adequate clearances around air
openings and adequate accessibility clearance
for service and proper operation. Never obstruct
the front or back 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. 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.
The vent termination is hot while in
operation 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 20 for ordering
information.
These fireplaces are designed as
supplemental 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
6
solid fuel burning appliance.
