Leak Check
Gas Leak Testing
WARNING
Fire and Explosion Hazard
●
Ensure test pressures are below 40in-wc (100mbar).
●
DO NOT use matches, candles or other sources of
ignition when checking for gas leaks.
●
Use a gas leak detection liquid or equivalent.
●
Make certain to re-test all fittings after making
adjustments to loose connections.
Failure to follow instruction may lead to serious injury,
property damage or death.
1. Verify the power switch on the water heater is in the “OFF”
position. (Fig. 18)
2. Turn on the gas supply or alternative pressure supply.
3. Check the appliance and all gas connections for gas leaks
with leak detection liquid (not provided) or an equivalent
gas leak detection method. Bubbles indicate a gas leak
that must be repaired.
4. Repair gas leaks as needed.
5. Repeat gas leak check after any adjustments to loose
connections.
NOTE:
After leak checking, make sure the gas supply
pressure corresponds to the operating pressure of the
appliance 11~14in-wc (27.4~34.9mbar).
Water Leak Testing
1. Verify the power switch on the water heater is in the “OFF”
position .(Fig. 18)
2. Turn on the water supply to the unit
3. Open water faucets to fill the system with water. Close the
faucets when the water is flowing smoothly and all air is
