Location

Check

Is the make-up air supply free from corrosive elements and flammable vapors?

Is the water heater clear of combustible materials?

Is the gas control valve accessible for servicing?

Have you maintained the proper service and maintenance clearances?

Gas connection

Check

Have you tested all the fittings for leaks?

Does the gas supply match the gas type specified on the water heater's rating plate?

Is the gas supply pressure adequate as the gas supply pressure specified in the water heater's rating plate?

Does the installation conform with local codes or, in the absence of local codes, the National Fuel Gas Code ANSI Z223.1/NFPA 54?

Does the gas line have an inner diameter of at least 1/2"?

Water connection

Check

Is the water supply pressure sufficient (greater than 40 PSI)?

Have you verified that the cold water line and the hot water line do not intersect and have you tested for leaks?

Is the approved pressure relief valve installed properly?

Have you verified that there are no products installed which exceeds the maximum pressure specified in the water heater's

rating plate?
