That is why manufacturers of unvented catalytic heaters suggest opening two vents or windows, one low and one high. Vented catalytic heaters have no such requirement and are therefore more effective because they do not also have to compensate for cold ventilation air as does an unvented heater.
This isn't true, and it's dangerous for folks to believe it is. Room oxygen consumption is the primary cause of CO poisoning from exposed burn propane-fired heaters, and ALL such heaters require an open vent or window for room air replenishment/safe operation.
The "venting" on the Plat Cat is at least billed as for exhaust only.... Combustion air is supplied from the room, and resupply has to be provided the same way one does with a Wave/Blue flame/whatever.
In fact, since the fan's actually pushing air out along with whatever "pollutants", isn't it possible that the Platcat may require MORE intake venting than a Wave????
