20.6 Safety Shut Off Valve Check

After the initial start up and gas pressure adjustment,
verify gas soundness of each SSOV (Safety Shut Off
Valve). This check must be repeated after the first
100 hours of operation.

20.7 Temperature Control System Calibration

The temperature control system components are
factory calibrated to a base resistance so that
component replacement will not upset the system
calibration. If the temperature control system should
require field calibration, refer to the provided
temperature control amplifier product information
sheet.
