mostly the subject say it all. since the current blower is way too noisy, i'm removing it so there is now a hole behind the stove, do I put a metal sheet to close it or should i leave it like that?
need to know make of stove-- most current wood stoves the blower is simple a heat distribution item . so in theory it is not needed to close hole. as it likely just mounted to a heat shield. to be 100 % code compliant if it is a heat shield mount and depending on spacing from combustible materials then yes.
Wood stoves : XVR-II I removed the blower and it seem the back look like a heat shield, just to be safe i put a small metal sheet (cut from an single wall dryer pipe) to close it, i think it should be enough
From what I often read here is that any blower is installed where the metal housing or heat conventional plate(s) are on the stove. It’s not directly involved in the fire and just blows air in the internal cavity then the stove heat sheild is the thinner outside. Good thing to close it off if it’s exposed or a bigger hole than you’d like to see. If anyone with little hands decided to push that limit...that’s a very hard lesson to learn. Personal experience too.
If the inlet of the blower was open to the room then just leave it open. You probably will get some thermosiphon circulation albeit small. Can't help but ask, how would removing the blower make it quieter than just leaving it turned off ?
On my Englander 30NC, the blower mounts to the lower part of the rear heat shield. I had to remove a piece of the heat shield (just 4 screws IIRC) to install the blower. As Chris said...to be 100 percent compliant with clearance specs, If I remove the blower, I "should" put that original piece back on. Now....all that being said, will the world implode if I didn't? Probably now. If I didn't have the piece to put back, I'd have a good hot fire and keep checking the wall behind it to make sure it wasnt getting too hot. If all was good, I'd never look at it again.
Just another thought, if you have little ones maybe a cover would be a good idea. Junior's little rubber ball would probably smell great melting away....
and prehaps you though burning in a new stove & piping was a bit over the top- that at least goes away after a few firings - jr toy will be around for several seasons (got T shirt)
