Two-Stage Gas Fired Warm Air Furnace
Users Information Manual
10318825 August 2001 (4)
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 to circulate conditioned air during cooling operation.
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 GUSA
furnace has been designed with efficiency and flexibility in mind. It is capable of
operating on low stage or high stage, in accordance with current heating require-
ments.
The GUSA furnace 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.
