A. Connecting the Gas Piping
Refer to Fig.16 for the general layout at the boiler. It shows the basic fittings you will need. The gas line enters the boiler from the right side jacket
panel. The boiler may receive the gas supply pipe through the left side, or rear jacket panel by relocating the gas valve connector and pipe assembly.
The boiler is equipped with a 1/2-in. NPT connection on the gas valve for supply piping. The following rules apply:
1. Use only those piping materials and joining methods listed as acceptable by the authority having jurisdiction, or in the absence of such
requirements, by the National Fuel Gas Code, NFPA-54-2002/ANSI Z223.1-2002. In Canada, follow the CAN/CGA B149.1 and .2
installation Codes for Gas Burning Appliances and Equipment.
2. Use pipe joint compound suitable for propane gas on male threads only.
3. Use ground joint unions.
4. Install a sediment trap upstream of gas controls.
