A gas appliance includes a pair of separate manifolds which each supply gas to two burner assemblies. Each manifold includes a relatively short and straight steel tube having a central section with a generally square-shaped cross-section and end sections with generally circular-shaped cross-sections, and a pair of end plugs closing the end sections to form a sealed interior space. The end plugs and the tube are swaged together at the end sections to form a gas-tight seal. A pair of bolt-through type valves are associated with each of the manifolds to regulate flow of gas from the manifolds to the burner assemblies. The valves have inlets directly secured to the manifolds and outlets connected to the burner assemblies with burner tubes. A pair of light-weight aluminum supply tubes connect a gas inlet with the two manifolds. The supply tubes are preferably secured to the manifolds with bolt-through type adapters located at the longitudinal centers of the manifold tubes and between the two valves.
