Wall exit burn hotter?

[BillsWS]

In the BK Princess manual the rear clearance increases by 5" for the stove and pipe when installed with a 90* stove pipe to a wall thimble vs. a straight up exit. Does the stove burn (that much) hotter with the 90* (I will use two 45* if there is room) instead of roof exit?

I'm wondering if this is just bad documentation and they mean rear exit vs top exit? That makes much more sense. Call for clarification from Blaze King.

When I was installing mine I was curious to why they have it listed that way. I'll be watching for the answer!

I'm only 6 inches off the wall but it's a solid masonry wall so I moved it to the minimum allowable distance that BK lists.

There isn't a rear exit option on the Princess.

Doh. / :red: of course. Seems to be based on an assumption of single wall pipe. Which they don't recommend. It doesn't make a lot of sense when using double-wall connector.

Any chance it has to do with the horizontal section? ie - maybe the shortest pipe section they make means the stove has to be 5 more inches from the wall to fit? Or maybe they want the horizontal pipe-to-90º fitting joint to be a bit away from the wall so you can see if it's connected properly?

Hmmmm. I never thought of the distance from the wall. I think code requires the class A to be 2 or 3 inches into the room, so you might be on to somehting here Cozy.

BeGreen, right below the picture you posted from the manual, page 22: Due to the high efficiencies of these units, Blaze King recommends the use of
double wall pipe from the stove top to roof or wall exit. I think in another place in the manual it says use single wall pipe IIRC.

I went over the installation instructions and found them a bit frustrating. There were so many exceptions that they just should have done a separate table for double wall pipe vs single wall. Not the best docs that I've read.
