fuel gas valve to reduce ignition noise, regulate gas flow,
with electric switch gas shut-off; flame proving sensor, hot
surface igniter, dual pressure switch assembly, flame
rollout switch, ICM blower and two speed inducer
assembly, 40va tra nsformer; low-voltage (heating)
(heat ing/cooling) thermostat.
Blower Wheel and ECM Blower Motor
Galvanized blower wheel shall be centrifugal type,
statically and dynamically balanced. Blower motor of
variable speed ECM type shall be permanently lubricated
with sealed ball bearings, of _______hp, and suppli es
delivers requested airflow CFM as defined by signals
received from EZ-SELECT airflow control when 24V
motor inputs are provided. Blower motor shall be direct
drive and soft mounted to the blower scroll to reduce
variation transmission.
Filters
Furnace may have reusable-type filters. Filter shall be
_______ in. (mm) (x) _______in. (mm) An accessory high
efficiency Media Filter is available as an option.
_______________ Media Filter.
Casing
Casing shall be of .030 in. (.76 mm) thickness
minimum, pre-painted galvanized steel.
Two Speed Inducer Motor
Two Speed Inducer motor shall be soft mounted to
reduce vibrati on transmission.
Flame Rollout Switch
Flame Rollout Switch shall be factory installed near
burner area to further reduce the possibility of a stuck gas

Multiple operational settings available with the
EZ-SELECT fan control, including, separate blower
speeds for low hea t, high heat, low cooling, high cooling
and continuous fan. Continuous fan speed may be adjusted
from the thermostat. Cooling airflow will be selectable
betwee n 350 or 400 CFM per ton of air conditioning.
Features will also include temporary reduced airflow in the
cooling mode for improved dehumidification when an
Infinityt Control or Thermidistatt is selected as the
thermostat.
