I have 2 blodgett 1000's stacked with stone decks. They are great for pizzas, bagels, and artisan breads. I teach in a high school that is brand new. I was part of the design team for my room and the company that supplied all the new commercial appliances-venting system, floor, tables, mixers, sinks, etc, (the blodgetts are from 1976) is a friend. He told me that people contact his company all the time about putting commercial kitchen stuff in their exisiting and new home plans. He said that for a licensed vendor/service person to install or work on one in a home, the home must be up to commercial standards and if they are called in to service on one that is not up to the standards remove it. He also told me of people who have designed a new home to commercial specs just to have their kitchen! Like Tom said, make sure you have enough gas pressure and they put out a lot of heat. They are 120,000 btu's each. I wonder if dealing with the gas company would raise a red flag and being a detached garage make things different/exempt?? As far as working on them, it is no sweat. A monkey wrench, screwdriver, channel lock, a couple open end wrenches are all that is needed to replace most every part. Kind of like being able to work on an old car with a basic tool kit........... Most of them need the gas safety valve/thermal coupler replaced from the non servicable mercury original to a magnetic retro part(the red button you have to hold to light the pilot. I could easily work on my ovens but have to have a licensed repair person do it. They are set up for easy access for repair/replacement parts. I prefer the stone to steel decks. For home use the 1048 would be more than you would ever need. .I can tell you once you get to using one the home oven will never satify you again! Walter
PS: Blodget sells an inexpensive propane converion kit. Tha might be something to look into to.
