INTRODUCTION
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 in-
stallation.
The Electronic appliances have an electronic
intermittent pilot ignition system. External
electrical power is required to operate these
units. The battery back-up can be used in case
of a power outage.
These vented gas fireplaces are sealed combus-
tion, air-circulating gas fireplaces designed for
residential applications.
Use Only These Approved Vent Components:
These fireplaces are designed, tested and
listed for operation and installation with, the
following (4-1/2" inner and 7-1/2" outer) vent
components 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

WARNING
Young children should be care-
fully supervised when they are
in the same room as the appli-
ance. Toddlers, young children
and others may be susceptible
to accidental contact burns. A
physical barrier is recommended
if there are at risk individuals in
the house. To restrict access to
a fireplace or stove, install an
adjustable safety gate to keep
toddlers, young children and
other at risk individuals out of
the room and away from hot
surfaces.
AVERTISSEMENT

surveillés étroitement lorsqu’ils

viennent en contact avec la sur-
face chaude. Il est recommandé
d’installer une barrière physique
si des personnes à risques habi-
tent la maison. Pour empêcher
l’accès à un foyer ou à un poêle,
installez une barrière de sécu-
rité; cette mesure empêchera les
tout petits, les jeunes enfants et
toute autre personne à risque
d’avoir accès à la pièce et aux
surfaces chaudes.
