Switch from propane to house gas

Done some looking but haven’t found anything to help with this specific issue.

I have a propane smoker that I want to run off house gas to make things cheap and simple.

I bought an adapter that goes from 3/8 gas line to the little green bottle adapter fitting. Hooked the hose up and screwed it into the regulator on the smoker. It lights but as expected the btu content is so low it won’t get over 190 degrees and wind blows out the flame. I thinking there is an orifice to drill out (5000 btu burner so #80 bit) but before I go do that I wanted to check if that’s the rights way. Will the regulator (which is my flame control) cause any issues? Is there a better way to do this?

you have to change the orifice out to natural gas size.

Natural gas runs at a lower pressure . That's why you have a lazy flame . As said in post 4 you need the smaller orifice to work with the lower pressure for natural gas . Maybe they make a kit for the brand of smoker you have .

Yup if your house is natural gas you will need to make some changes away from propane gas fittings. But at all cost keep safety in mind.

Your burner delivers too many BTU's... Mod the burner also... Here are some methods to lower the BTU's..... along with orifice size change and line pressure adjustment... Use a needle valve to control gas flow also.....
