 It is normal and desirable that this valve allows a small quantity of water to be

discharged during the heating cycle. If it discharges more than a standard bucket

of water during a 24 hour period or discharges continuously there may be another

problem

 If water continuously dribbles from the valve, try easing the valve gear for a few

seconds as described in the section ‘Maintenance and Regular Care’ on page 6.

This may dislodge any foreign matter and alleviate the problem.

 Check to ensure the electric isolating switch(es) at the switchboard (usually marked

“Hot water” or “water heater”) is switched ‘ON’.

 Check to ensure that the electric fuses for hot water at the switchboard are intact

 Check the temperature of hot water delivered with a thermometer placed under the

closest outlet (usually the kitchen sink) on a non-tempered hot water line

 This test should be done early in the morning after overnight electrical boosting

before any hot water is used. The temperature of the water delivered should be at

least 55°C (allowing for heat losses in pipe work)

 If this is not the case or the temperature may need to be increased. Contact your

installer or Rinnai to discuss adjusting the thermostat.
