RT-Series Typical Applications
Solid Fuel Fireplaces
and Ovens
Mutiple Clothes Dryers Common Vented
Chase Exhaust for Kitchens & Baths or Dryers
Multiple Heaters
Atmospheric Gas with Draft Hood/Diverter
Draft COP (DCOP1)
1) Intercepted call for heat activates Draft COP.
2) Draft is measured and compared to set point.
3) Inducer ramps up to meet draft set point.
4) PSA-1 fan prover closes enabling burner call circuit.
5) Inducer modulates to maintain draft set point as flue gas
volume, building pressure, stack effect and winds change.
6) When call for heat is satisfied Inducer maintains draft set
point for post purge time setting and shuts off.
UCRT
1) Intercepted call for heat activates Inducer.
2) Inducer speed determined by manually adjusted setting.
3) PSA-1 fan prover closes enabling burner call circuit.
4) When call for heat is satisfied Inducer operates for
post purge time setting and shuts off.
Exhaust COP (XCOP1)
Triggered by an external switch or constantly operating, the
Exhaust COP maintains a negative exhaust pressure set point by
modulating the speed of the Rooftop Inducer to meet demand.
