Gas Fuel Connections
The local Gas Company should be consulted for the requirements for installation and inspection of
gas supply piping. Installation of gas supply piping and venting must be in accordance with all
applicable engineering guidelines and regulatory codes. All connections made to the boiler must be
arranged so that all components are accessible for inspection, cleaning, and maintenance.
A drip leg should be installed in the supply line before the connection to the boiler. The drip leg
should be at least as large as the gas piping connection on the boiler. See Figure 23 and Figure 24
for piping suggestions.
