Due to the modularity of the TopTier™ Modular Brewing Stand, which is its best feature, you are required to purchase a couple pieces of 1/2" pipe and assemble a gas manifold for it.
For example, you could have one-, two- or three-burner tiers (balance being shelves) needing fuel, and these can be installed on any of the four faces at any height. Had we designed a limited fixed configuration stand like our competitors, we would have included the piping. But that means you'd be stuck with that configuration and could never change it as your equipment, batch size and brewing process changes and develops.
Fortunately, we do include nearly all the fittings you'll need. With the product, you'll receive a black iron tee, a brass flare adapter for each tier, and also a plug to cap off the top of the manifold. All you'll have to provide are the straight lengths of pipe, which are readily available in a variety of lengths at your local hardware store or home improvement center. If you want a specific length, many of these stores will cut and thread your pipe to length for free or for a small fee. If you don't have a plumbing-supply store nearby, McMaster-Carr is an online source for these parts.
The manual provided with the stand includes detailed instructions and photos on assembling your manifold, which is a simple process. We also provide a nice stainless-steel, bellows-type gas hose to connect the burner to the manifold, as well as hardware to mount the pipe manifold to the stand. These are the more difficult and expensive parts to acquire that are not available at the above stores.
