## Questions & Answers

**Q: Hello, can you provide the link to the mounting, and ducting?  I can't find you "warm air accessory" page.  Can this be mounted outside?**
A: Hello, if we describe a warm air accessory' page we are most likely just referring to our Butler Technik web page, apologies for the confusion. Perhaps if you can message us and let us know exactly what items you require in addition. Thank you for your enquiry. David

**Q: It looks like it auto adjusts to at least 7,200ft(2200m), will adjust at higher altitudes without a modification? 12,000ft?**
A: Thank you for your question. That's correct, current standard factory units will only adjust for altitude up to max 7200ft 
see link https://www.butlertechnik.com/downloads/Webasto_Air_Top_EVO_Thermo_Top_EVO_-_Altitude_operating_ranges.pdf
It is possible for special order only eg military application etc to build for higher altitude operation. For single unit purchasers the 'special build' solution may be somewhat delayed and potentially cost-prohibitive. cost prohibitive

**Q: Does this heater needs high altitude adjustment at 9000 feet?**
A: This heater is not ideally suited to operate continuously at 9000ft

**Q: This one is diesel fuel.  Do you sell gasoline units of this model?  (altitude compensating)**
A: Hello, thank you for your enquiry. Yes, we can supply gasoline fired versions of this heater model EVO 40, though they are a special order from the manufacturer. Lead time is 14-20 days from order placement. Thank you once more

## Customer Reviews

### ⭐ RIPPOFF!! This is a FOREIGN built unit. NOT COMPATIBLE IN THE USA!!!
*by H***A on November 25, 2023*

I thought I was buying a USA unit as these are twice the cost of the Russian units. This is a ripoff!! I can't even use it as intended! Can't use a SmarTemp controller with it and the dial thermostat is clunky and sometimes acts up. This will be reported as fraud!

### ⭐ Russian
*by J***M on August 21, 2023*

You can tell by the cloth wrapped wiring. US versions have plastic sheathing. The problem, outside the wiring is the programming. It doesn’t work well if you change elevations. It has an electronic switch for elevations above 1500meters. These are junk if you need it to compensate for your elevation.
