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
installation.
The Electronic appliances are designed to op-
erate on natural or propane gas. An electronic
intermittent pilot ignition system provides safe,
efficient operation. External electrical power is
required to operate these units.
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 IHP,
•
Secure Flex
®
Flexible Vent Components
manufactured by IHP and
•
Z-FLEX
®
Model GA Venting Systems listed
to UL1777 and ULCS635 manufactured by
Flexmaster Canada Limited.
Children and adults should be alerted to the
hazards of high surface temperature and
should stay away to avoid burns or clothing
ignition.
Les enfants et les adultes devraient être infor-
més des dangers que posent les températures
de surface élevées et se tenir à distance afin
d’éviter des brûlures ou que leurs vêtements
ne s’enflamment.
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
Les jeunes enfants devraient être
surveillés étroitement lorsqu’ils
se trouvent dans la même pièce
que l’appareil. Les tout petits,
les jeunes enfants ou les adultes
peuvent subir des brûlures s’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.
GENERAL INFORMATION
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.
