This is part 2 of gas piping and regulator for a Rinnai tankless heater.
Since I received quite a few questions from last weeks video on regulators about the sizing of gas piping for the Rinnai.

NFPA 54 is where you will find the national gas code.
Look for the gas code pages in you plumbing or gas code book for your local county or state.

Pietro Florentini 3/4" regulator black spring #F30052AABVA
2 pounds in 8"to14" out set at 8" from factory

Easy gas flex full 3/4" you should keep 18" and 36" on your truck

REMEMBER TO ALWAYS AIR TEST YOUR GAS LINE FOR 1 HOUR AT 2 TIMES THE WORKING PRESSURE
WHEN I TEST MY 2 POUND GAS SYSTEM I TEST IT AT 10 POUNDS AND MY 10 POUND PROPANE SYSTEM I TEST IT AT 25 POUMDS JUST TO BE SAVE.
SOAP TEST WITH GAS TEST SOAP ALL YOUR FITTINGS EVEN DURING THE 1 HOUR TEST.
PAINT ALL YOUR GAS PIPING INCLUDING THE THREADS WITH ENAMEL GRAY OR YELLOW PAINT.

If you have a question or would like a Rinnai guy sticker please e mail me at [email protected]
I hope you enjoy this video,
Mike
