How to Convert a Blackstone Griddle To Bulk Propane

Blackstone Griddle Bulk Propane Tank

The Blackstone 17″ and Blackstone 22″ griddles come equipped to use a 1 pound propane tank. These small propane tanks are great when you’re camping or on the go with the griddle, but unfortunately, they don’t provide many cooking sessions before needing a refill or replacement.

One solution is to convert your Blackstone 17″ or Blackstone 22″ griddle to a larger bulk propane tank. You lose some portability, but this may be an excellent option if the priority is more propane and more cooking sessions between fill-ups. Here’s what you need to know when it comes to how to convert a Blackstone griddle to bulk propane.

Bulk Propane Tanks

Bulk propane tanks can carry significantly more propane than the 1 pound tank your tabletop griddle comes equipped to operate with. Your typical bulk propane tank is a 20-pound tank, so that’s 20 times more propane at your disposal. 

Though the 20-pound bulk propane tank is the most common, various bulk propane tank sizes are available. Here are some of the more extensive options available for purchase to choose from.


As previously mentioned, the larger the propane tank you use, the less portability it has. The reduced portability is due to the size and weight of the tank. Here are the approximate weights of each tank when empty and once filled with propane.

Tank Size Weight Empty Weight Full
30 lbs. 24 lbs. 54 lbs.
20 lbs. 17 lbs. 37 lbs.
5 lbs. 9 lbs. 14 lbs
1 lb. 2 lbs. 3 lbs.

How to Convert Your Blackstone Griddle to Bulk Propane

Converting your gas griddle to a larger propane tank is not too complicated, fortunately. All you need is a new propane regulator and a few minutes. 

Blackstone sells a replacement regulator for the conversion; however, quite a few 3rd party options are available from Amazon and work just as well, if not better.

Once you have the replacement regulator in hand, here are the steps to convert your Blackstone griddle from a 1 pound propane tank to a bulk propane tank.

Step 1:

Make sure your Blackstone griddle is turned off and cool. Unscrew the one-pound propane tank from the griddle regulator. 

Step 2:

Take your replacement adapter hose and screw it into the griddle regulator from which you removed the 1 pound tank.

Step 3:

Next, connect the other end of the adapter hose to your bulk propane tank. Screw the connector onto the propane tank, making sure it’s on tight. 

Step 4:

Your griddle is now converted to a bulk propane tank. Now, test the new connection to ensure it’s working correctly. 

Step 5:

Slowly open the bulk propane tank and then light your griddle. Check if it lights properly and the flames from the burner (or burners if you have the 22″ model) look good.

Final Thoughts

One of the great features of a tabletop griddle is its portability. Being able to quickly and easily transport it allows you to take it to many places. When you are going to be stationary, a larger propane tank can undoubtedly be more valuable. Fortunately, you can take advantage of this simply by using a bulk propane adapter.

The bulk propane adapter can be installed or removed quickly, allowing you to easily switch between a 1 pound propane tank and a bulk propane tank. This flexibility will enable you to use the smaller tanks when camping or tailgating and bulk propane when at home.
