NATURAL GAS : PIPE SIZING CHART

Natural Gas (NG) flow is given in 
thousands of BTU/hr. = 1 cubic 
foot of NG gas - 1000 BTU

Nominal pressure at the burner 
for Natural Gas is 3.5” of water 
column. (Typical machine supply 
5”-7”)

Pipe length must include 
additional length for all fittings. 
Add approximately 5 feet of pipe 
per fitting.

Natural Gas Example: A machine 
with a burner that requires 
440,000 BTU would need a 1 -1/4” 
pipe for a 20” long run. 

LIQUID PROPANE : PIPE SIZING CHART

NOTE: The sizing charts above list the specific pipe sizes required for the amount of BTU’s for a new gas line installations. If you 
are using an existing gas line you must take into consideration the existing gas line capacities to ensure you will have proper 
pressure. 

This chart is for reference only, we recommend you consult with a Licensed Plumber/Gas Fitter or NFPA54 (National Fuel 

Gas Code - current edition) for more details.

Liquid Propane (LP) Gas flow is 
given in thousands of BTU/hr.  =
1 cubic foot of LP gas - 2500 BTU.

This chart refers to low pressure LP, 
after regulation, Standard nominal 
pressure at the burner for Liquid 
Propane Gas is 11” of water column.

Pipe length must include additional 
length for all fittings. Add 
approximately 5 feet of pipe per 
fitting.

LP Example: A machine with a 
burner that requires 440,000 BTU 
would need a 1” pipe for a 20’ long 
run.
