This is a beautiful product.  Great fit and finish.  One of the best of any 'assemble to own' products I have every purchased.  In fact, it is all but impossible to tell that it didn't come out of the crate pre-assembled.  Packed very carefully.  Not a singe flaw anywhere.  Takes a couple of hours to build, but not complicated at all.  The furnace itself works great.  Instant heat.  Easily warms the specified cubic footage coverage and then some.  I highly recommend this product.
