Why it matters to you

It is why installation details that look like preference — venting arrangements, clearances, combustion air, equipment listings — are not negotiable. On the coast, floodplain and wind provisions administered alongside it can also affect how and where equipment is mounted.

What to do about it

Code editions are updated periodically and local amendments exist, so requirements should be confirmed with the authority having jurisdiction for your address rather than assumed from a general source — including this one.
