HEAVY DUTY (HD) HEAT SOURCE
•
Ensure that filter at water inlet is clean.
NOTE: that this is an ‘O’ ring seal and does not need to be
excessively tightened. Just make sure ‘O’ ring is engaged inside machined surface in brass housing.
Isolate water supply to DD before removing filter for cleaning and inspection. Ensure water in storage
cylinder is not excessively hot before removing HD inlet filter.
•
Ensure all HD (s) are operating. Ensure power is available to HD (s) if it is not operating. Check Socket Outlet.
Ensure power is available to the HD (s) before applying power to thermostatic controller and pump(s).
•
Many new jobs or ones where the gas supply has been modified need to purge the gas supply lines as they
are full of air. Purge should be carried in accordance with AS/NZS 5601, Appendix 'D'.
•
Look at flame through inspection window for conical shape, blue base and yellow tip. Flame height will vary
if heater is modulating. Inspection window is located behind the front cover on the burner unit (next to flame
rod) of the appliance.
•
All HD models: when operating the number displayed should be higher than the temperature setting on the
thermostatic controller.
•
Eg Tank = 65°C,HD = 75°C. These are factory standard settings.
•
Eg Tank = 82°C, HD = 85°C. These are the maximum allowable settings.
•
All HD models will display a fault number if one has occurred. The following table lists all of the fault codes.
•
In jobs that operate for long hours and/or in dusty or smoky environments the combustion air fan may become
dirty. This may be indicated by fault 10. Contact Rinnai Service.
•
Internal heaters may operate for a short period of time and then stop. This can be caused by the flueing not
being pushed together properly and exhaust gases are re-entering the inlet air. Push the flue together to
remedy this. Also inspect flue terminal for any cause to divert exhaust air back into the inlet air. Ensure flue is
terminated correctly in accordance with AS/NZS 5601.

Extended flue: Installation where the total flue length exceeds 7 metres (refer to table below), the
SW1 of both DipSW1 & DipSW2 are set to '
OFF
'.
For Internal (FFU) models only (except HD210i)
