Install a Drip Leg in Gas

Supply Piping

Foreign matter could lodge in gas valve cutoff seals, resulting in gas leak-through, explosion or ﬁre.

Install a full-size drip leg or dirt pocket in the piping directly ahead of the main shutoff valve to capture foreign matter.

Provide Over-pressure Protection

CSD-1 requires that if gas pressure entering the building exceeds the rating of any gas train component an overpressure protection device must be installed.

Standard – An Underwriters Laboratories (UL) listed gas train is standard for the CG10 gas burner. This conﬁguration also meets CSD-1 requirements. See Figures 8A and 8B for typical component layout.

Propane (LP) – When the correct propane restrictor is added to a burner’s gas pipe assembly it changes the burner’s gas pressure drop so that the propane pressure drop is equal to the natural gas pressure drop of the same BTU ﬁring rate. That is why the Manifold

to Furnace Pressure Drop curves of Figures 14A, 14B, and 14C are correct for both propane and natural gas. That is also why a gas train adjusted for the burner’s natural gas requirements will be correctly adjusted for its propane requirements. R. W. Beckett provides the same pressure regulating safety shutoff valve in the gas train (usually a Honeywell V4944B) for both natural gas and propane. The valve is marked for natural gas due to its primary usage in a pressure range normally used by natural gas appliances. It is safe and effective for propane usage in this design application.

Optional – Gas trains for IRI and FM are available and must be speciﬁed when ordering a burner.

Verify – Verify that the train components are not damaged and all piping and ﬁttings are clean inside and out. The gas train is normally shipped as components and must be assembled and installed at the site.

Vent Lines – Install vent lines to any gas valve component that requires atmospheric air pressure to balance a diaphragm. Vent lines must be run to the outdoors, with the termination point away from fresh air intakes and windows. The terminal opening must be ﬁtted with a wire mesh screen to block insects and other contaminants from entering the vent and must be mounted in such a position that water, ice, dirt, or any other foreign matter cannot inﬁltrate and block the vent piping. Make sure the ﬁnal assembly is anchored securely.
