@HVACRSurvival

Correct, this is a direct fired unit. The CO levels are very low. As you know, Co is from incomplete combustion. It's hard to have incomplete combustion when you're cramming that much air behind the burner.

I have found when you have such a large inconsistant minimum, yet pressure drop is o.k. someone enlarged orifice holes during cleaning. Probably too big a drill bit was used. This scenario also could come from someone enlarging holes trying to get more heat out of it. (Re-engineering) They accomplish a higher overall temp. drop on that super cold day, but screw you forever on the mild days. Good video!

Any idea why the flame would start high then goes low and stays there, the modulator is good, remote temp selector seems to be good, now it could be either air discharge sensor or amplifier, when replacing air discharge sensor with 10k ohms potentiometer the amplifier reacts to the resistance variation and flame get adjusted. When measuring the air discharge sensor resistance it's within range. What do you think about this situation?
@HVACRSurvival
@HVACRSurvival Жыл бұрын
There should be a potentiometer on there that tells it how fast it's to react. It's either set too sensitive or not sensitive enough.

@@HVACRSurvival thank for your reply, by lowering sensitivity that did make it work. However, even at high temp like 90F modulator doesn't stay fully open, only 2-4 second then goes to 8-9V instead of 24V, I thinking maybe air discharge sensor is not responding right to heat?

Was I understanding that right that the combustion products mix into the warm air stream for the building?
@HVACRSurvival
@HVACRSurvival 4 жыл бұрын
Yes but remember carbon monoxide is a result of incomplete combustion, incomplete combustion comes from improper air and fuel mixture, there is a lot of excess air with this so there's not a lot of Co. it's really no different than a salamander or a unvented wall heater. Also remember they have exhaust fans on, pulling it out the other side. This heat is just to temper the air, not warm the building.

@@HVACRSurvival I'd actually bee thinking of possible excess CO2 and reduction in O2, but I guess that probably isn't a problem in this use. BTW, I've never seen an unvented furnace or water heater where Iive. Different part of the country, I guess.
