The Fatal Venting Error in Room 225, This weeks video

I'm surprised this doesn't happen more often, based on some things I see in the field……….

Its kinda amazing that this continues to happen . It makes me think who are the idiots who do these types of job without any clear thoughts of the end results just plain stupid or just kids listening to a blind eyed owner or sales guy . i Kinda believe that also that most gas pool heater should not installed within a building unless hard wired in a co monitor which dis engages the power to the unit. The saddest and stupidest is hotels where the pool pump and filters are housed in the same indoor mech room w all the pool chem w usually zero outside combustion air and in a few cases no indoor transfer grills to allow fresh building air into the room . The other note is most pool guys do not service pool heaters ain t there jobs so they usually go un serviced and usually that's part of the issue as the draft collector rots and drops on the heat exchanger and bang you got a issue and it s been a while since servicing a gas pool heater but i would gather two spill switches might help being i don't ever remember seeing them but i'm old and forgetful now .

Thanks Ray

peace and good luck clammy
