6.3.2 Burner reaction
Checking of the burner reaction has to be made by sight and function control. The flames have to
burn stable and not yellow, not to lift up or flash back.
6.3.3 Heat Load and Test for leakages
For this check the right nozzles and the correct connection pressure. Further make a leakage test.
6.4 Maintenance of the bearing and the drive chain
Please check at least quarterly, more often if necessary, the fat content of the bearing and the
chain. If this is not the case, you have to renew the fat, so it can work perfectly. Please use for the
new fat only heat-resistant fat. If you disregard it, the bearing could take damage. If this is the
case, the spit rotation will not work.
