What gas appliances are not required to be vented?
Thursday, July 25, 2019
Here’s the list from the 2018 International Fuel Gas Code (IFGC) of appliances that do not require venting:
Three appliances on the list, #5, #9, and #11, would not be used in a residence. And it’s important to note that the word “listed” is repeated again and again. All gas appliances must be listed—which means tested and approved—by an accredited testing agency, such as UL, for their intended use; and #11 essentially says that, if it is listed for unvented use, then it’s okay.
There is a further restriction, however, for items #5 thru #11. If the output of the appliance(s) in a room exceeds 20 BTU/hr per cubic foot of room volume, then ventilation is still necessary.
