Definition from Noloâs Plain-English Law Dictionary When a criminal defendant is convicted of two or more crimes, a judge sentences the defendant to a certain period of time for each crime. Sentences that may all be served at the same time, with the longest period controlling, are concurrent sentences.
A wood stove application is very different. The paper on gypsum board is combustible as are the wood studs behind them. With a wood stove the greater concern is pyrolysis which happens to the wood behind the drywall or plaster as it is heated over a long period of time. It's combustion point is lowered and eventually can it catch fire at much lower temps.
The vent connectors are of NG boiler and water heater and I was wondering what is the proper clearance to combustibles for this type of installation. These vents appear to be single wall vents. I was under the impression that 9 is required and for the boiler (vent on the right) it is barely 3/4 to the rotted drywall. My 2 questions are, what is the clearance required for this type of installation? When measuring clearance is drywall considered combustible? In the picture the vent on the right is the boiler.
