INTRODUCTION

These appliances are designed to operate on
natural or propane gas. An electronic intermit-
tent pilot ignition system provides safe, efficient
operation. External electrical power (110 vac)
is recommended to operate these units. If the
system operates on line voltage with 6V fan
control module, four (4) "AA" batteries can be
used as a backup in case of a power outage. The
electronic appliance can be operated without a
fan, solely with four (4) "AA" batteries.
These vented gas fireplace heaters are sealed
combustion, air-circulating gas fireplaces de-
signed for residential applications.
Approved Vent Components - These fireplaces
are designed, tested and listed for operation
and installation with, the following vent com-
ponents only:
• Secure Vent™ Direct-Vent System Compo-
nents manufactured by Security Chimneys
International,
• Secure Flex™ Flexible Vent Components
manufactured by Security Chimneys Inter-
national and
• Z-FLEX™ Model GA Venting Systems listed
to UL1777 and ULCS635 manufactured by
Flexmaster Canada Limited.
Use only the correct size venting (4-1/2" inner
and 7-1/2" outer).
These approved vent system components are
labeled for identification. DO NOT use any
other manufacturer's vent components with
these appliances.

GENERAL INFORMATION
