Liquid Propane (LP) Gas flow is given in thousands of BTU/hr. (This chart refers to low pressure LP, after regulation )
One cubic foot of LP gas = 2516 BTU
Pipe length must include "additional length" for all fittings.  Add approximately 5 feet per fitting.
Standard nominal pressure at the burner for Liquid Propane Gas is 11" of water.
Aaladin uses the same orifice for all propane burners: #63

Liquid Propane Example:
A machine with a burner that requires 440,000 BTU would need a 1-¼" pipe for a 20' long run.

Natural Gas flow is given in thousands of BTU/hr.
One cubic foot of Natural Gas = 1000 BTU
Pipe length must include "additional length" for all fittings.  Add approximately 5 feet per fitting.
Nominal pressure at the burner for Natural Gas is 3.5" of water.  (Typical machine supply 5"-7")
Aaladin uses the same orifice for all propane burners: #52

Natural Gas Example:
A machine with a burner that requires 440,000 BTU would need a 1-¼" pipe for a 20' long run.
