My husband and I are considering purchasing the stove that is described
in the text below for our home. Are we crazy? Are we asking for a
torched house?

You should verify that Southbend will honor the warranty on a commercial
range used for residential installation. They typically use local service
agencies who are commercial, and may or may not do work in your home. Also,
I have been selling and repping kitchen equipment for 12 years, and I would
NEVER sell a commercial piece for someone to use at home. You may need to
call around to buy one, and will likely not find a commercial service shop
to do install or repairs.

In response to a previous answer, the gas pressure CERTAINLY DOES matter, as
much as the size of the hose. Just because you have a 3/4" hose, doesn't
mean that you have enough PSI to operate to full potential. You;d need a
plumber to verify this.
