Install the regulator properly with gas flowing as indicated by the arrow on the casting
*NOTE - Do not install the regulator too close to the heating equipment or use in very cold environment. Heat or cold can change the resistance of the spring inside the regulator

KINDLY NOTE

WARNING: The NPT thread size is NOT referring to the size of the thread itself!
The plumbing industry standard for the pipe sizes is NOT always as straightforward as measuring the pipe
Measuring the pipe will often mislead you into choosing the wrong pipe size
The "pipe thread size" is measured and based on the inside of the pipe
A lot of people measured the thread / the opening for the thread/outside diameter！
