Components shall include: slow-opening dual rate gas valve to
reduce ignition noise, regulate gas flow, with electric switch gas
shut-off; flame proving sensor, hot surface igniter, pressure
switch assembly verifies inducer operation; flame rollout switch,
drain tubing and installed condensate drain trap, blower and in-
ducer assembly, 40va transformer; low-voltage (heating) (heat-
ing/cooling) thermostat.
Blower Wheel and Blower Motor
Galvanized blower wheel shall be centrifugal type, statically and
dynamically balanced. Blower motor of PSC type shall be per-
manently lubricated with sealed bearings, of _____ hp, and shall
be multiple-speed direct drive. Blower motor shall be soft mount-
ed to the blower scroll to reduce vibration transmission.
Filters

(x) ______in. An accessory high efficiency Media Filter is avail-
able as an option _____________Media Filter.
Casing
Casing shall be of .030 in. thickness minimum, pre-painted gal-
vanized steel.
Two Speed Inducer Motor
Two Speed Inducer motor shall be soft mounted to reduce vibra-
tion transmission.
Primary Heat Exchangers
Primary Heat exchangers shall be 3-Pass 20 gauge corrosion
resistant aluminized steel of fold-and-crimp sectional design,
which operates under negative pressure.
Secondary Heat Exchangers
Secondary Heat exchangers shall be of a flow-through design
having a patented interior laminate coating of polypropylene for
greater corrosion resistance with fold-and-crimp design, which
operates under negative pressure.
Controls
Controls shall include a microprocessor based integrated elec-
tronic control board with at least 11 service troubleshooting
codes displayed via diagnostic flashing LED light on the control,
has ability to store fault codes, when activated a self-test feature
