This morning it was 26 C in my shop. By this afternoon it will be pushing 34 C. In a few months it will be pushing 44 CIt was 26F this morning outside and 44F in the shop.
I did it last year already. It worked out great. I bought a kit online to convert it. I changed the jets in the burner and the pilot, and changed the spring in my existing valve. I saved a lot of money heating my shop with NG instead of LP.Marcel
You will need to change the jets in the burner and also either a different gas valve or get the right spring in your existing valve to match the NG pressures. Propane and NG run at different pressures.
