Fire Risk.
Explosion Hazard.
High pressure will damage valve.
•  Disconnect gas supply piping BEFORE 
pressure testing gas line at test pressures 
above 1/2 psig.
•  Close the manual shutoff valve BEFORE 
pressure testing gas line at test pressures equal 
to or less than 1/2 psig.
B.  Gas Pressures
Proper input pressures are required for optimum appliance 
performance. Gas line sizing requirements need to be 
made following NFPA51.
C.  Gas Connection
Verify inlet pressures.
•  High pressure may cause overfi re condition.
•  Low pressure may cause explosion.
•  Verify minimum pressures when other household
