of trafc and away from furniture and draperies.
Children and adults should be alerted to the
hazards of high surface temperatures and should
stay away to avoid burns or clothing ignition.
Young children should be carefully supervised
when they are in the same room as the appliance.
Clothing or other ammable materials should not
be placed on or near the appliance.
Surveiller les enfants. Garder les vetements, les
meubles, lessence ou autres liquides a vapeur
inammables lin de lappareil.
This appliance may be installed in an aftermarket
permanently located (mobile) home, where not
prohibited by local codes.
This appliance is only for use with the type(s) of
gas indicated on the rating plate. This appliance is
not convertible for use with other gases, unless a
certied kit is used.
Cet appareil peut etre installe dans un maison
prefabriquee (mobile) deja installee a demeure si les
reglements locaux le permettent.
Cet appareil doit etre utilise uniquement avec les
types de gas indiques sur la plaque signaletique.
Ne pas l utiliser avec d autres gas sauf si un kitde
conversion dertie est installe.
Any safety screen or guard removed for servicing
an appliance must be replaced prior to operating
the appliance.
When operating your Harman Serenity III Gas
Fireplace, respect basic safety standards. Read these
instructions carefully before you attempt to operate
the replace. Failure to do so may result in damage to
property or personal injury and may void the product
warranty.
Consult with your local building code agency and
insurance representative before you begin your
installation to ensure compliance with local codes,
including the need for permits and follow-up inspections.
Several issues must be addressed when selecting a
suitable location for your Serenity III Gas Fireplace.
Observing required clearances to combustible materials,
the proximity to a safe venting system location, and
the accessibility of the gas and electrical supply must
all be considered. In addition, selecting a location that
takes advantage of the building’s natural air ow is also
desirable to maximize the heating effectiveness of the
replace. In many cases, this is a central location within
the building.
The Harman Serenity III Direct Vent Gas Fireplace
is a listed gas-red direct vent room replace tested
by Intertek Testing Services/Warnock Hersey to ANSI
Z21.88-2002-CSA 2.33-2002. CAN-CGA-2.17-M91.
Also approved for installation into a shop.
The installation of the Serenity III Direct Vent Gas
Fireplace must conform with local codes, or in the
absence of local codes, with National Fuel Gas Code,
ANSI Z223.1 — latest edition and CAN 1 B1-149.1 and
.2 Installation Code.
Also for use in mobile (manufactured) homes after
home is sited.
Mobile (manufactured) home installations must adhere
to current editions of Title 24 CFR, part 3280, or CSA
Z240.4.
CAUTION: This appliance must be vented to the
outside.
Installation and repair of the Serenity III Direct Vent
Gas Fireplace should be done by a qualied service
person. The appliance should be inspected before use
and at least annually by a qualied service person. More
frequent cleaning may be required due to excessive lint
from carpeting, bedding material, etc. It is imperative
that control compartments, burners, and circulating air
passageways of the Serenity III be kept clean.
When the blower is off the air
gate is in the open position
which allows air to ow freely
through the air chamber and up
through the heat exchanger.
Air Gate Open
Air Gate Closed
When the blower is turned
on, the air pressure from the
blower forces the air gate to
seal the air chamber. This
forces all the air from the
blower to travel through the
heat exchanger producing
two to three times more air
than other brands of gas
replaces.
Blower Off
Blower On
Air Gate Blower System
Typically in gas replaces the blower (which is usually
an option) is placed to blow air up the back of the rebox
without any method to keep the air pressure from being
lost. This method allows air to ow freely around the
blower when the blower is off but gives up a large
percentage of the blowers efciency when it is on.
The Air Gate Blower System gives you the best of
both worlds.
