Gas Line Connection (Typical) - NTI FTV110 Installation And Operation Manual

Lighting the Boiler│
When performing a pressure test on the gas line piping, be sure the boiler is disconnected
or isolated if the test pressure is expected to exceed 1/2 PSI (14 in. w.c.), as damage to the
gas valve could occur resulting in fire, property damage, serious injury or death.
Manual Gas Shutoff Valve
Should overheating occur or the gas
supply fails to shutoff, close the Manual
Gas Shutoff Valve to the boiler.
Drip Leg
Union
Test all gas piping, internal and external to the boiler, for leaks. Failure to follow these
instructions may result in fire, property damage, serious injury or death.
