Extremely hot air going to my chimney?
Hello,
We recently had a new furnace installed. It's a goodman GMH8 (goodmanmfg.com).
I've read all the available documents, but can't seem to figure this one out... (I am NOT an hvac guy what so ever)
There's a 6" pipe that goes from the inside of the furnace, presumably the blower... to my brick chimney. the pipe traverses about 4 feet of distance.
4 feet away from the furnace, where it enters the chimney, the metal pipe is too hot to touch for more than 2 seconds.
where the pipe goes into the furnace, the outer metal of said pipe is too hot to touch without getting a blister.
there's some kind of vent installed on the pipe itself, which i guess is a backflow limiter of some kind... it's a balanced piece of metal that hangs vertically. it is set up in such a way that if the furnace wanted to suck air in thru that pipe (from the chimney) the hanging metal flap would not allow the air to be sucked in from the basement. alternatively, if the chimney was totally blocked up, the flap would allow air to be pushed out of this pipe into the basement.
i was able to move the flap in such a way where i could stick my hand into the pipe leading from the furnace to the chimney, i wanted to feel the air. sure enough, the air is forcibly blowing and very hot. the air felt heavy, like it would probably coat my hand in water if i left it in there long enough.
so i guess there's 2 questions: is the hanging flap installed properly?
and, why is there such extremely hot air being pushed out into my chimney and eventually out of the house?
the air coming out of my registers around the house could be hotter.... its just "warm"... it feels kind of odd to me, I think a furnace should push hotter air.
