Q. DOES THE IGNITER SPARK?
A. NO:
1. Check that the batteries are installed correctly and hold a positive charge.
2. Detach your gas supply (turning off gas supply will not release built up pressure so you must detach
gas supply to perform troubleshooting.)
3. Attempt running water through the unit with the gas supply detached. If your unit sparks the igniter
without the gas supply attached you may have a gas regulator with an outlet pressure too high.
Required gas pressure - 11"WC LPG - 8"WC NG
4. If the unit fails to spark the igniter with the gas supply detached, there may be an issue with the
microswitch used to control the electronics.
5. Remove the dial from the front of the unit and center the water flow and gas flow levers.

10. If a spark is produced when doing so, the unit micro switch has failed. If no spark is produced,
the unit computer board or battery compartment is faulty.
To test for a faulty battery compartment
With unit cover removed, remove the red and black wires from the top of the battery compartment. Tape
