We recently replaced an existing single gas pressure regulator feeding that was feeding three boilers with three new dedicated pressure regulators to improve pressure control. The pressure after the new regulators was fluctuating until we disconnected the new ½” vent lines connected each of the regulator vent ports. The boiler technicians indicated that the pressure regulator vent lines were under sized and this was causing pressure fluctuations on the gas lines feeding the boilers.
The three new vent lines are ½” galvanized pipe, 60’ ft long and have about five 90 deg elbows. Is there a “rule of thumb” or local code (California) for sizing gas regulator vent lines based on the length of the pipe?
Can you please point me in the right direction? I am not afraid of reading but I just can’t seem to find the appropriate source for this information.
Thanks,
Celso
