PZ100RL Biotech Pellet Boiler Service Bradford

Biotech PZ100RL pellet boiler troubleshooting and maintenance. The boiler hadn’t been operating for a while.

Burner grate cleaning

The burner grate was covered with a thick layer of clinker.

Lambda sensor cleaning

The lambda sensor had to be removed for cleaning. Unfortunately the nut was damaged and the factory recommended lambda tool could not be used. It didn’t fit on the nut. Our self developed extra short lambda tool did the job.

The lambda sensor seals were also too rigid to seal properly. As a temporary solution I put there some fire retardant silicone, but the washers will be replaced along with the nut during next maintenance.

Fire bowl replacement

I found some holes on the fire bowl which may cause various problems, so it had to be replaced.
