So this ND0310A-600 pilot assembly is exactly what you need if you're fixing a ProCom vent free heater. It works with both natural gas AND propane - comes with both orifices preset so you don't have to mess with that. The 600mm dual wire thermocouple is fast-acting, which means it shuts down quick if there's a problem. Fits a bunch of brands actually - Cedar Ridge, Kozy World, Empire Comfort, all those vent free units. The brass orifices are rated for 3-3.5 WC for natural gas and 8-11 WC for propane. Comes with dual ceramic electrodes too. If your pilot keeps going out or won't stay lit, this replacement should fix it. Much cheaper than buying a whole new heater. Just make sure you get the right model number - this ND0310A-600-P is specific to certain units. If you're comfortable with basic gas appliance repair, this is a straightforward swap. Way better than paying a technician hundreds to do the same thing.
