Buderas motorized exhaust question
My house came with a 20 year-old Buderas natural gas boiler ( with baseboards). Last winter is worked ok. Had it cleaned this summer, but now there is a faint gassy smell in the basement. The smoke/carbon monoxide sensor has not gone off. Going to he back of the boiler, looking up at the motorized exhaust damper, it seems to open just a little ( see photos: first image is in the closed position, second image shows the damper at maximum opening, when pushed with a probe). Should it be opening more than this? Thanks for any comments about this!

It should fully open.
DON’T operate the boiler unless it opens fully!
You and your family are at a risk of carbon monoxide poisoning!
You should have it checked immediately by a competent technician or the gas company.

Thanks for the warning. Any idea what could cause the damper to not open fully? Any way to manually open it until the technician arrives?

It shouldn’t allow the burner to fire if it’s not fully opened, so something is seriously amiss.
No, I don’t see any way that you can safely bypass it under those circumstances.
