For Gas Operation: Operate the left-hand switch to the ‘on’ (flame) position. There will be a pre-purge pause of
approximately 5 seconds to allow any un-burnt gas to leave the flue and will extinguish when the water is up to
temperature. A green LED will light upon successful flame ignition. If there is air in the gas supply line, it may take a
few attempts for the gas to ignite. See Section 9 for gas lockout re-setting. If the ignition is not satisfactory, the red
diagnostic LED will flash - refer to the Trouble Shooting Guide (see Section 9).
For Electric Operation: The Water Heater is equipped with twin 600W / 1200 W immersion heater elements offering
operation at 600W or 1200W. Operate the right-hand rocker switch to the top position
element. To turn on both electric elements, operate the right-hand rocker switch to the bottom position.
