Testing propane furnaces with a portable tank

Is it possible to test propane furnaces with a gas grill tank?

YES.

I agree with Brian…YES. But, before you do that please contact your E&O and General Liability insurance provider and add me as an “Additional Insured”…I’ll figure out later how to file a claim.

Yes, but it is not the preferred method, because you can check the lines for leaks, but you don’t get the long term test that you get with the gas hooked up.
