I have run the Diesel heaters on gas but it won't work running the gas heater on Diesel . Gas being more volatile than Diesel readily ignites in a DA-6.. The Diesel version has a pre-glow cycle and is controlled by a ECU.

The BA-6 doesn't pre-glow, there is no combustion valve which restricts the combustion air in order to heat up the burn chamber quickly, or a small quantity fuel pump which delivers a lesser amount of fuel on start-up. These are components that  Diesel  needs.
Same reason a Diesel engine needs glow plugs.  
 I have two of the DA-6 in stock for sale- I need to find two temp sensors to make them work on the high setting.
E-mail me for more info-

Subject: BA6 & DA6 aux heaters

I'm trying to get some information on aux heaters for an 86 Syncro.  I tried
calling Automotive Heater Technology, but they are no longer there.  I want
to install a diesel heater, and want to know where it goes in relation to
all the Syncro drive components and also if I can convert a gas heater to a
diesel heater.

Thank you.

Sincerely,

Craig Rogers
