I'm going to try converting my Weber Smokey Mountain 18.5 to propane

Post by ed-ct » July 6th, 2018, 10:06 am

Got it as a gift over the holidays and have smoked st louis ribs, beef ribs, and a pork shoulder. The results were good but not great.

The reason I expressed interest in smoking meat was for brisket.

One of the problems I had was maintaining a proper charcoal fire, and the time spent on the shoulder suggests I look at alternative heat sources for type of time needed for beef brisket.

Some quick research showed weber smokey mountains modified for propane, lng, and electric. I'd like to try propane first with a box for wood.

It looks like cutting open one of the lower vents for the burner is common.



Some things I don't know:

high pressure vs low pressure (i assume low)?
how many btu burner will i need?
Is something like this all I need?

Images welcome





Any input/suggestions/recommendations welcome.

I was planning to do this as a winter project but maybe it will be easier than I expect. Thx

That's way too much burner. I'd guess 12 or 15,000 btu and low pressure is plenty . I'd work on maintaining a charcoal fire or electric but most folks that have them love them .


If it's tourist season, how come I can't shoot 'em?

Thanks for responding! I'd really like to move away from charcoal since ultimately I'd like to do 12 hour+ briskets.

Going electric seems easier too, maybe that's a better first modification, looks cheap and is easily reversible.



ok, so assuming I continue the propane route:

12 or 15k btu burner should work for a wsm 18.5
low pressure hosing/regulator/controller


I'm going to check on parts and see what i can come up with.

Propane is best left to a grill. If you don’t want to tend fires, go electric burner or pellet.

Go to this site and you'll learn how to run your charcoal no problem. I've done briskets with charcoal on 18.5 and 22 WSM's. Only time they're fussy is in high winds.
