PRODUCT FEATURES

OpERATION
This heater is clean burning. 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 coals. This
heater is designed for vent-free operation with
flue damper closed. It has been tested and ap-
proved to ANSI Z21.11.2 standard for unvented
heaters. State and local codes in some areas
prohibit the use of vent-free heaters.
SAFETY DEvICE
This heater has a pilot with an Oxygen Deple-
tion Sensing (ODS) safety shutoff system. The
ODS/pilot is a required feature for vent-free
room heaters. The ODS/pilot shuts off the
heater if there is not enough fresh air.
IGNITION SYSTEM
This heater has an electronic ignitor to light
heater fuel supply.
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.
During 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.
Exhaust fans, fireplaces, clothes dryers and
fuel burning appliances draw air from the house
