TANKLESS WATER HEATER ISOLATION VALVE KIT INSTALLATION GUIDE
6. Repeat steps 1 through 4 to install the HOT water isolation outlet valve assembly onto the outlet
connection of the water heater. Please note that there should NOT be a shut off valve located between the
tankless water heater and the pressure relief valve.
INSTALLING THE GAS CONNECTOR*:
*Furnished in select Jones Stephens installation kits
WARNING: Gases can be ignited by a spark or flame which may result in property damage, personal
injury and/or death. Do NOT reuse connectors or join connectors together. Turn off gas supply at a gas
ball valve near the appliance. If a shut off valve is not near the appliance then the gas must be shut off
at a main valve.
7. Clean all male and female pipe threads with a wire brush. Ensure that connections are free of any dirt or
debris. Apply the appropriate thread sealant or gas-approved yellow thread tape to the male pipe threads.
8. Thread the adapter fitting onto the gas supply valve. Tighten with wrench.
9. Thread the other end of the gas supply line to the water heater. Do not use thread sealant or tape to the
flared ends of the adapter. Do not stretch or kink the gas connector.
10. Do not turn on the heater until all of the connections have been leak tested. Do not use matches or
flames to test for leaks. Use a clear water and soap solution or a liquid designed specifically for leak detection
to test for leaks.
11. To purge the air from the water line, turn on a faucet (at the furthest point from the appliance) and then
turn on the water supply. The valve should be in the fully open position to ensure proper operation. When
the water flows freely (without any air in the line) then the system has been purged and you can turn off the
water.
12. To purge the air from the gas line, turn on the gas supply and then turn on another gas appliance such as
a stove. This will purge any air from the gas lines. WARNING: Do not turn on the tankless water heater until
the water and gas lines have been bled and all of the connections have been leak tested. If any gas leaks
are detected, retighten and retest for leaks. Wait at least 10 minutes for any gas vapors to dissipate before
turning on the tankless water heater.
WARNING: Please install in accordance with all local code requirements.
