HI I have a wave 3 heater in my northern -lite 10' 2 camper its sits near the door it has only been used a few times . thought i would try it today as its a new camper. temp out side was 36 degrees...
There's nothing that says the entire pad HAS to glow, that's a function of the LP jetting. I have 3 NOX detectors, one with a display at the top of the wall only a few feet away, and it has never budged off of zero with this heater running.
