PRODUCT FEATURES
OPERATION
This vent-free fireplace 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 realis-
tic flames. When used without the blower, the fire-
place requires no electricity making it ideal for
emergency backup heat. This heater is designed
for vent-free operation. It has been tested and ap-
proved to ANSI Z21.11.2 standard for unvented
heaters. State and local codes in some areas pro-
hibit the use of vent-free heaters.
SAFETY DEVICE
This fireplace 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 system shuts off the fire-
place if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This fireplace has a piezo ignitor. This system re-
quires no matches, batteries, or other sources to
light fireplace.
OPTIONAL BLOWER ASSEMBLY
(GA3700 SERIES & GA3700TA
SERIES)
This fireplace accepts an optional blower assem-
bly (not included). The GA3700TA Series blower
operates thermostatically and features a variable
speed control. The GA3700 Series blower oper-
ates manually and also features a variable speed
control. The blower circulates heated air from the
fireplace into the room. See Accessories, page 29.
AIR FOR COMBUSTION
AND VENTILATION
WARNING: This heater shall
not be installed in a confined space
or unusually tight construction
unless provisions are provided
for adequate combustion and ven-
tilation air. Read the following in-
structions 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. During heating months, home
owners want their homes as airtight as possible.
While it is good to make your home energy effi-
cient, your home needs to breathe. Fresh air must
enter your home. All fuel-burning appliances need
fresh air for proper combustion and ventilation.
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.
