Diagram 3: Typical Multiple Boiler Manifold Construction
*Based on Table 1 on the following page for natural gas, 0.6 specific gravity, 1,000 cfh/unit, actual header sizes will
vary with length of pipe run and fittings employed. For propane gas (1.6 specific gravity, 2,520 BTU/FT3) header
sizing, consult NFPA 54.
If supply gas pressure exceeds 14.0” W.C., a single header gas manifold lock-up type regulator, -or- individual lock-up
regulators can be used to bring the gas pressure down to 14.0” W.C. Header should be located above or behind boiler.
Gas piping should not be installed directly over top or front of any part of boiler. Sufficient clearances for maintenance
are required.
