1. WATER HEATER FAILS TO IGNITE/HEAT WATER
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 o 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.
Recommended outlet pressure is 11”WC.
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 dials from the front of the unit
6. Removethecoverfromtheunit-screwsarelocatedatbottomrearcorners
7. With cover removed, locate red and blue wires running from computer board (bottom le corner) to
the micro switch (front and center). e wires are connected with using white connectors.
8. Detach the white connectors from each other, thus separating the computer board and micro switch.

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
two“D”cellbatteriesinaseries(congurationasfollows:+[battery#1]-+[battery#2]-).Withthe
