The appliance and its individual shut off valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual
manual shut off valve during any pressure testing of the gas supply piping system at test
pressures equal to or less than ½ psi (3.5 kPa).
The gas pressure will be between these values 3.5 in W.C. (870 Pa) 10.5 in W.C.
(2610 Pa) for natural gas and 8.0 in W.C. (1990 Pa) 13.0 in W.C. (3230 Pa) for liquid propane.
The appliance should be located in an area where leakage of the tank or connections will not
result in damage to the area adjacent to the appliance or to lower oors of the structure. When
such locations cannot be avoided, it is recommended that a suitable drain pan, adequately
drained, be installed under the appliance. The pan must not restrict combustion air ow.
Do not obstruct the combustion air intake or heater exhaust and ensure air intake is not near
an area that will allow chemical fumes to enter the combustion air system.
Do not use to heat pools or spas (hot tubs) that use chemically treated water.
If a water heater is installed in a closed water supply system, such as one having a backow
preventer in the cold water supply line, means shall be provided to control thermal expansion.
Contact the water supplier or local plumbing inspector on how to control this situation.
