Hi
I am getting ready for a sleigh show on the 20th and want to use my Clark 
Heater.  Does anyone know how to fuel the heater?  It has a drawer with two 
porous blocks that my husband thinks you soak in fluid and ignite the blocks 
and then adjust the vents.  So far this has not worked.  I thought you would 
put coals or coal into the drawer and let them  burn adjusting the vents.
Does anyone know the correct way to work the heater? or have any ideas?
thanks
