## Description

Maxitrol Pressure Regulator for Natural Gas (NG) Product Description: Brand: Maxitrol Gas type: Natural Gas (NG)Refer to the pictures on how to find the correct pipe thread size. This regulator has 13/16" openings for 1/2" gas pipes. 1/2" IN and 1/2" OUT Female Pipe Thread. The 1/2" gas pipe means interior diameter 1/2" but outside diameter is 13/16", refer to the pictures before buying.Inlet pressure (CSA rated and Maximum operating): 1/2 PSI (34 mbar).Outlet pressure range: 3” - 6” Water ColumnAmbient operating temperature range: 32°F - 225°F (0°C - 107°C). Attention: NOTE: GAS PRESSURE REGULATORS WILL NOT TURN OFF THE FLOW OF GAS.The pipe fittings for this regulator are based on NPT pipe threads - dimensions according ANSI/ASME B1.20.1 standards.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. How to find the correct pipe thread sizeWARNING: 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 of the pipe, and thought that was the thread size. It was WRONG.The NPT thread is referring to the Interior Diameter of the pipe.

Review: BBQ gas regulator. Worked like a charm - My built in bbq was not working like it should. So glad I found this regulator. It fixed my problem and saved me a ton of money. I would have had to pay someone to come fix it $$ or worse buy a new bbq $$$$.
Review: Works well, but I had to adjust it to increase the gas flow as my grill was not getting hot enough. - It seems to be a high quality regulator, all connections were easy to make. After using my grill again after replacing my old regulator with this one, I found that the grill was not getting hot enough even on the high setting. I removed the screw cap and adjusted the gas flow using a screwdriver, and then did it a second time to get the flames to the right heat level. Now the grill is back to normal heat range.

## Questions & Answers

**Q: Does the opening size matter if I use reducers?  3/4 thread down to 1/2 thread**
A: Why don't you just buy the correct size? Yes, you can use the reducer.

**Q: I need to reduce 13.5” to 6-9” range. Do you have a recommendation for that?**
A: This Product could be a good candidate for you. Using a digital manometer I recorded my feed pressure at 14.7"H2O and outlet pressure at 6.2"H2O.

**Q: What is the max btu hour input for this? my needs are for 125,000.**
A: Sorry - you many need to check the manufacturer's website for this.

Thanks

**Q: How do you adjust this to get 1/2 PSI gas out for low pressure grills?**
A: You can not get 0.5 psi outlet pressure from this regulator. This regulator is designed to have a maximum inlet pressure of 0.5 psi and will provide pressure less then its input depending on what spring the regulator is equipped with.
