GAS REACTIVATION CONTROLS:
All controls are tested at the factory, so very little adjustment should be necessary. The main gas
pressure regulator may require some adjustment to meet the burner requirements and to regulate the gas
pressure available upon installation. Gas reactivated dryers have an air proving switch and an adjustable high
temperature limit device (manual reset) which must be energized to allow the burner to ignite.
NOTE:
The reactivation high temperature limit (manual reset) must be set according to
the set-up sheet in this manual. It may require adjustment and resetting before igniting the
burner.
Because of various insurance requirements, Bry-Air uses several gas control systems and components.
The following applies on a general basis.
Procedure:
1. Set the reactivation temperature control to the design temperature specified on the set-up
sheet in this manual.
2. Turn the main and pilot gas cocks to the "Open Position” (handle aligned with gas line).
3. Turn the dehumidifier control switch to the "HAND or ON" position.
4. Reset the low gas pressure switch located near the gas train.
5. Press the red reset button on the flame safety control inside the control enclosure. The following
will then take place:
A. React fan motor will be energized.
B. The combustion controller is energized and will program as follows:
1. A short pre-purge period.
2. The ignition transformer is energized.
3. The pilot valve opens.
4. Pilot is established and proven.
5. Ignition drops out and the main gas
6. Main burner flame is established.
valve opens.
NOTE:
Some smaller capacity gas burners do not incorporate pilot systems. See the Gas Piping
Schematic in this manual for more information.
The system is ready for normal operation. On initial start up, the system may shut down on failure; it
may take several attempts to purge the air from the gas lines. After a short reset period, (30-60 seconds)
the safety controller may be reset for another start sequence. For more detailed information concerning the
combustion controller, consult the data sheets enclosed in this manual. The temperature control dial may
require calibration to match the actual air temperature. Refer to the instructions included with this manual.
