8 ADJUSTMENT

This section describes how to adjust the Model P-5050 Thermoelectric generator.

Note:  Typical settings are 41 to 48 kPa (6.0 to 7.0 psi) for natural gas and 48 to 55 kPa         

(7.0 to 8.0 psi) for propane.

Note:  Good record keeping is necessary for long term follow-up. Use the TEG Performance 

Log,  located at the end of this manual, for recording details each time adjustments 

are made or servicing is carried out.
