REMOTE cONTROl AccESSORiES

There are four optional remote controls
that can be purchased separately for this
fireplace insert:
• wall switch
• wall thermostat
OPERATION
This vent-free fireplace insert is clean burn-
ing. It requires no outside venting. There is no
heat loss out a vent or up a chimney. Heat is
generated by both realistic flames and glowing
embers. When used without the blower, the
fireplace insert requires no electricity making
it ideal for emergency backup heat.
SAFETY DEvICE
This fireplace insert has a pilot with an Oxy-
gen Depletion Sensing (ODS) safety shutoff
system. The ODS/pilot is a required feature
for vent-free room heaters. The ODS system
shuts off the fireplace insert if there is not
enough fresh air.

AiR FOR cOMBUSTiON AND VENTilATiON

WARNING: This heater shall
not be installed in a room or
space unless the required vol-
ume of indoor combustion air
is provided by the method de-
scribed in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, the
International Fuel Gas Code, or
applicable local codes. Read the
following instructions to insure
proper fresh air for this and
other fuel-burning appliances
in your home.
Today's homes are built more energy efficient
than ever. New materials, increased insulation
and new construction methods help reduce
heat loss in homes. Home owners weather
strip and caulk around windows and doors to
keep the cold air out and the warm air in. Dur-
ing heating months, home owners want their
homes as airtight as possible.
While it is good to make your home energy
efficient, your home needs to breathe. Fresh
air must enter your home. All fuel-burning ap-
pliances need fresh air for proper combustion
and ventilation.

PIEzO IGNITION SYSTEM
This fireplace insert has a piezo ignitor. This
system requires no matches, batteries or

BLOWER ASSEMBLY
This fireplace insert is equipped with a blower
assembly. The blower operates thermostati-
cally and has a variable control. The blower
circulates heated air from the fireplace insert
into the room. Use of blower is optional.
Exhaust fans, fireplaces, clothes dryers and
fuel burning appliances draw air from the house
to operate. You must provide adequate fresh
air for these appliances. This will insure proper
venting of vented fuel-burning appliances.
PROVIDING ADEQUATE
vENTILATION
The following are excerpts from National
Fuel Gas Code ANSI Z223.1/NFPA 54, Air
for Combustion and Ventilation.
All spaces in homes fall into one of the three
following ventilation classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 6 through 8 will help
you classify your space and provide adequate
ventilation.
Unusually Tight Construction
The air that leaks around doors and windows
may provide enough fresh air for combustion
and ventilation. However, in buildings of un-
usually tight construction, you must provide
additional fresh air.
Unusually tight construction is defined as
construction where:
