I recently posted about a indoor wood boiler. I was wondering if there is anything in the IPC/IRC/IMC that requires a heat dump zone for boiers in the event of a power outage? When we had our Greenwood 100 installed we requested that it be "protected" by a dump zone for power outages to minimize the chance for boil overs. It seemed like a reasonable request but we did not get that. I expect a TP valve is required at the least. Looking for some recourse on a job gone bad and the installer will not do the work to make it right. Any thoughts?
