I've just bought an Essex 1000. I know very little about such equipment but, being young and inexperienced, (69) I dove blindly in to this task. The unit was built in 1982 but was used less than 2 seasons (a friend owns it so I'm acquainted with the history). It is now installed inside a 4000 sq ft building and set up to provide heat thru the floor as well as hot water. I will have to remove it and ultimately install it at my place. My thoughts are to use registers/radiators inside central heat systems in both my house and my shop here in NW Arkansas, locating the boiler unit in an old well house equal distance between the 2 buildings which are approx 100 ft apart, My total sq ft will be approx 3300 sq ft. The big problem (that I'm aware of) is that I don't have any manuals or other paperwork to cover assembly, installation, operation or maintenance and have been unsuccessful in contacting the mfg in Conn or Mass by telephone or internet. I need to know the following: 1) Does my installation scheme seem sound? 2)Tips on disassembly/inspection/assembly. 3) Are manuals or drawings available and if so how can I get copies? 4) Is there a special cleaning/maint kit required, if so where do I go to get it? Any advice will be appreciated. Thanks, C.W.
