Customer Question
It tries to light but...
we have a buderus gb142 combi boiler giving error code 6L. It tries to light but is not successful. If we cover combustion air 50%( approx) it coughs and spurt and eventually lights but out of condensate drain we are seeing small amount of smoke. It runs until it reaches set point and then won't relight automatically. Any tips or input?

Hello, the average life of those boilers is in the 10 year range, few last longer than 15 years, with your eroded away fin problem its time to replace that boiler.

c

To address the firing issue, inspect the exhaust fan (blower wheel) it may be falling apart as well, that will cause this problem.

Click here for the service manual. see paged 86 and 87 tell me if any of those error codes are showing up, 6L code is not shown however... it could be a code that just looks like a 6 or some such.
