Safety - using Ooni inside...
I would NEVER use the Ooni indoors with or without the gas unit.
I must say I've been really surprised to see multiple people claim they use the gas unit and use the Ooni inside rather than outside. Claiming to use chimney extensions, open windows, etc.
Aside from the natural fire hazard of a mishap the issue of carbon monoxide poisoning is not to be considered so trivial. Is Ooni properly warning purchasers of the gas option of the hazards of cooking indoors?
Maybe its just folks in the EU, but in the US we've been warned for years about the hazards of using gas indoors. I'm rather shocked at the number of facebook Ooni group users who claim they cook indoors with the gas attachment.
