Refer to Table 11 for Schedule 40 metallic pipe length
and diameter requirements for natural gas, based on the
total of all PRESTIGE Solo Boiler inputs (divided by
1,000 to obtain cubic feet per hour required).
- Table 11 is based on Natural Gas with a specific
gravity of 0.60 and a pressure drop through the gas
piping of 0.30”w.c.
- For additional gas piping sizing information, refer to
A
NSI Z223.1. For Canadian installations refer to
CAN/CSA B149.1.
