Can I hook up my propane fireplace to my propane grill?

Yes, you can easily hook your propane fireplace up to your propane grill. They use a common fuel and a common set of connectors so, other than possibly having a cable or hose that might be a little short, you can easily set this up. Be careful when you are setting things up so that all of the parts are connected securely and that any ground connections that have to be made are done correctly because adding extra pieces to your propane system can easily open you to problems later on. The key to the ability to set up this system is the fact that propane systems are based on same-sized parts.
