Can someone give me a good web site on the inspection for the AD for this heater. I downloaded the AD from the FAA site but it does not go into detail on the inspection, such as how to pressure check the pressure switch.

This is a reliable outfit I have used for years. On their Website, click on the Tech Page. There you will find all of the ADs and Manufacturer’s Service Bullitens you will need to service your heater. They have repair and parts manuals, as well as test equipment and spare parts, for sale. They also repair separate units, or entire heater assemblies. Their phone number is on the site and they are always helpful. I wrote heater articles for the August and September issues of The Twin Cessna Flyer that may contain useful info. Good luck – Larry Denning
