Mr. Heater 4 inch Stainless Steel Horizontal Vent Kit for Big Maxx MHU50 and MHU80 Unit Heaters, One Size, Metal

We bought this for my heater in my greenhouse, it was easy to install for my husband and his cousin. There is a lot of extra pieces we didn’t need but who knows where I’ll use those pieces

Plenty of parties to install in just about any position.Looks great

the contents of this kit did not match what it said on the mr. heater site..maybe they changed b4/after. however, this kit is best intended for a corner mount of the heater so that the piping turns 45 degrees and exits either side wall.mine was mounted parallel to rear wall and i could not use the 45 degree piece of pipe , so i was 12" short for the un... had to buy that piece and get it shipped here b4 i could finish the job. kit also includedx a 3" to 4" adapter piece .. not sure why as the mr heater 80k btu already terminates in 4" .. so another wasted piece and lenth that i could not use.this kit is pricey in canada..$400 .. went to port huron MI and got it for $217top quality piping with it;s integrated silicone seals

Worked perfect used every piece

Great product. Super expensive

Was not devil walled?Did not have straps like it showed in the pictures. Do not like anything about what I received would like to return it if possible. Did not even take it out of the box? Does me absolutely no good. That's why I'd like to return it.How would I go about doing that? Or can I still returning ?

I bought it so I wouldn’t have a big problem venting my Mr Heater 80K and this made it easy

Other than being outrageously overpriced worked great
