    I would try

    Nelson & Small. 207 775-5666 in Portland, ME. They were the biggest sellers of the 1001 back in the day. That product hasn't been manuf for 15+ yrs now. I just happen to be at Rinnai today, so I'll go see what I can find, if it exists.

    The 132 Air inlet elbow is available. The 1004F 520X03 is the right part number. The FOT-40-3. We just looked it up and you can use a part number 1004F-530X01 and use the current vent kit for the 1004 the FOT-151. The 151 is the standard vent which will adapt from a 4 1/2" to 9 1/2" wall thickness

    That's the best I can do!

    Thank you!

    Jack, thanks so very much for your time and help! I sincerely appreciate it and will contact Nelson and Small. The 1001 I purchased was so clean and appears to have only been used as a demo. It is spotless. I got lucky and purchased it at auction from one of the local retailers here in Northern Ca. I took the system to my local LP company and they tested it and it runs absolutely perfect....all be it missing the parts required to install it. The size of the heater is way over kill for my room size but I paid only 275 for what appears to be nothing more than a demo unit. Thanks again!

    Nelson and small.

    Nelson and Small's heating division was purchased by Webber Supply. They only deal in commercial laundry now. Webber supply's phone number is (207)767-0201.

    thank you

    This may explain why Nelson never responded to my request.

    I tried...

    getting some parts last year similar to yours. I was advised to not fix it and just buy another unit.

    In Mikes case, based upon his

    Description of the unit, it is certainly worth getting "available" parts to repair. The 1001 hasn't been produced for at least 15 yrs. As parts cycle through the recommendation would be to go with a newer modulating burner and fan unit, if your particular need cannot be fulfilled. If I was told by distribution that a part was nla, I'd check direct with the factory before replacing...depending on the general condition and history of the unit .Some parts are just NLA at this point.
