Am seeking advice as to how to remove the gas-fired furnace in my Scamp.  It is not obvious to me how best to do this, and I am seeking directions or comments from anyone who has done this before.

Or, if necessary, suggestions on where to get such information, or names of reputable companies I could/should contact if necessary. I live in WA state, so WA/OR/CA firms could be considered if all else fails.

Thanks.
