Care and Maintenance Maintenance Filters All maintenance and service are to be performed by a qualified service technician, preferably one who has attended Rinnai service training classes on the Direct Vent products. Dirty filters reduce the air flow and the appliance’s ability to produce heat. The filters should be cleaned frequently during the heating season. If the filters become blocked the filter indicator lamp will flash and the appliance will beep.
Before Making a Service Call Before making a service call please check the following: At Ignition: Heater does not operate. Is the heater plugged in? Have the fuses or breaker blown at the fuse box / breaker panel? Is there a power failure? Is the air filter blocked? Is anything blocking the outlet for the hot air? Is the flue blocked? Warm air does not flow when the burner lights. The fan is started automatically after a short delay.
Fault Codes If there is a malfunction the appliance may shut down as a safety precaution and display a fault code to assist in diagnosing the problem. The fault code will flash in the display on the control panel. When making a service call, this code will assist with diagnosing the fault. CODE DISPLAYED You may be able to clear the fault code by turning the heater off and then on again.
Restart Function If the appliance fails to ignite, the appliance will attempt ignition after 1 hour. The “Ignition Failure” fault code, 11, will appear during that hour and disappears after a successful ignition. If ignition fails again, then the fault code will remain and another attempt to ignite will occur in 1 hour. The fault code is not stored in the fault code history. If the flame is extinguished during forced combustion then the appliance will attempt ignition after 1 hour.
Installation Instructions General Instructions WARNING Do not use substitute materials.
