Harry,

The manual may be misleading when we use the word "propane" which should have been "startup gas". The startup gas' properties will vary depending on altitude and outside temperature. The best all around gas is the propane/butane mix for reasons mentioned above. Next manual revision will reflect this change.

Please understand that reply to RCU post might be a bit slow so for best reponse time, please use our direct email. Thank you.
