The manufacturer proudly states that this heater will run on diesel fuel as well as on kersosene. However, in using #2 diesel fuel the heater belched out enough flames and fumes to simulate tear gas. According to the red tag attached to the heater, fuel changes may require "air pressure adjustments" to the heater. The reader is referred to the operating manual. Fair enough -So I read the section on "adjusting pump pressure" on page E-4.

The manual, however, talks about the "fuel pressure adjustment screw." To add to the confusion, the manual identifies ref. #29 on the exploded view parts diagram as the fuel adjustment screw. However, it is not even close. When I finally found the adjustment screw, it was somewhere else and it was labeled "output filter."

Until the trial and error process was completed, this unit spewed out enough crap to cause the CO2 detector in an open garage to go off repeatedly. (Hey, Consumer Products Safety Commission, are you listening?) Not only that, but it would only run for 2 to 3 minutes at a time before overheating and shutting down. There was another nearby adjustment screw which is not even mentioned in the manual; I can only guess that it also has something to do with the fuel mixture and/or pressure.

After several frustrating hours of tinkering, I finally got the damn thing dialed in and working. The user's manual was of little to no help. They talk about components which are not found on this model, and use a parts diagram which is not altogether consistent with this model. In order for this type of heater to work right, it is imperative that the air nozzle settings be adjusted correctly. Maybe, just maybe, it would be helpful to include clear and concise directions and diagrams for that purpose.

Bought this after a lot of reasearch; I have an un-heated un-insulated garage in Chicago area to work on my race-car. Needed to do a lot of maintenance this off season and the heater is certainly helping me work comfortably. I can get the temps in the garage to 58-65 when then outside temp are around 10-30.

Quieter than my old Craftsman. Burns Kero. and Diesel. Problem with a cracked fuel hose after a year was traced to faulty batch of hose. Customer Service (The real people at the manufacturer in Cleveland) were helpful in resolving the problem although i had already replaced the hose. Also has on/off switch unlike my old Craftsman. The free shipping made this a fantastic deal.

I bought this to heat my woodshop in my 900 sq/ft basement. I make sure I have some ventilation. It works great. I also bought the thermostat which I haven't tried yet but I will post a review when I try it out. I don't know how it works under heavy use (construction environment) but it works great for what I need it for.
