GAS PIPING
A properly sized gas supply system is essential for maxi-
mum oven performance. Piping should be sized to pro-
vide a supply of gas sufficient to meet the maximum de-
mand of all appliances on the line without loss of pressure
at the equipment.
Example:
NOTE: BTU values in the following example are for
natural gas.
You purchase a BCX-14G to add to your existing cook
line.
1. Add the BTU rating of your current appliances.
Pitco Fryer
6 Burner Range
Deck Oven
Total
2. Add the BTU rating of the new oven to the total.
Previous Total
BCX-14G
New Total
3. Measure the distance from the gas meter to the cook
line. This is the pipe length. Let's say the pipe length
is 40' (12.2 m) and the pipe size is 1" (2.54 cm).
4. Use the appropriate table to determine the total ca-
pacity of your current gas piping.
The total capacity for this example is 375,000 BTU. Since
the total required gas pressure, 345,000 BTU is less than
375,000 BTU, the current gas piping will not have to be
increased.
NOTE: The BTU capacities given in the tables are for
straight pipe lengths only. Any elbows or other
fittings will decrease pipe capacities. Contact
your local gas supplier if you have any ques-
tions.
