• A shut-off valve is not supplied with this unit but one should be installed.
• The appliance and its shut-off valves must be disconnected from the gas supply piping system during
any pressure testing where the pressure exceeds 1⁄2 psig (3.45 KPa) or the valve will be damaged.
• The unit 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 pressures equal to or less than
1⁄2 psig (3.45 KPa).

Always check for gas leaks with a soap and water
solution after completing the required pressure test.
NEVER USE AN OPEN FLAME FOR
LEAK TESTING.
