You have purchased a high-efficiency, gas-fired, warm-air residential furnace. It is
designed to heat your home efficiently and safely. It is also designed to interface
with your cooling equipment and to assist in circulating conditioned air.
Your furnace functions are regulated by an integrated control module which
responds to your home thermostat. This module controls all aspects of operation,
and is designed to assure efficiency, reliability, comfort, and safety.
The GUCA/GCCA furnace has been designed with flexibility in mind. It can be
installed in an upright or horizontal position. It can use either indoor or outdoor air
for combustion purposes. Use of indoor air, referred to as non-direct vent (single
pipe), requires only a flue pipe; combustion air is drawn from indoors. Use of
outdoor air, referred to as direct vent (dual pipe), requires both a flue pipe and a
combustion air intake pipe.
Your furnace is built to provide many years of safe and dependable service,
providing it is properly installed and maintained. Take time to familiarize yourself
with the information concerning furnace installation, features, operation, and
maintenance contained within this manual.
