Yes, the HOTTAP works with Butane as long as you have a gas hose that can plug from the HOTTAP into the Butane bottle. Our HOTTAP has a male GASKNECT fitting on the end of it.
If your gas hose doesn't have an adapter, we have the female GASKNECT on our website. You can connect this to your butane gas hose. You can purchase it here.
Read more about gas requirements from our Gas Types & Usage for HOTTAP page.
