I am renting a house and have a rannai 1004f monitor heater, my son dropped water on the control panel and now the system is saying function lock....Is there anything I can do to fix this myself?

Thanks Kerry

My rannai propane heater makes a whistling sound.

Check the fan. Unplug the unit and remove the panel that houses the fan unit. Electrical cleaner can be sprayed onto the connection points of the nicad heater elements as well as the fan motor. It may be that one of the heating coils has a bad connection. Take apart and reassemble heating elements and connection points.

I have a Rannai 2001 heater which was working well, it is getting power as you can see and hear the igniter trying to light the pilot light which is no coming on. so it is not lighting the heater as there...

Make sure you have not run out of gas first if you are on LPG bottles. Sounds silly but it happens alot.

If the gas is ok they you are likely looking at a problem which would need to be looked at by a decent service technican. Try the Rinnai NZ website, I'm sure they have a helpline and might have a list of service agents. Otherwise ask at any local plumbing or heating shop. Sorry can't help much more.

This is a water heater not a heater, sorry. Remove the ignition probe just below a small window and adjusst the gap after polishing the probes. Make sure all wires are connected good. Test fire unit.

I get an error code 12 on my rannai, filter is clean, flute is clear, exhaust is clear,, could it be a burner that went out?

Remove the two screws that hold on the front panel. Unplug the wire that connects to the ignition light. Now look about low center for a small plastic cover held on by two screws. Remove the cover, all three wires noting which wire went where, and remove both ceramic probes. There is a paper thin gasket that tears easy so be very careful. Take a small green scrub pad and polish the ends of the probes. Take a pair of pliers and adjust the bull-horn probes a little closer. Reinstall and test fire. If it continues, you will need to have the gas pressure tested.

I just bought a used Rinnai 1004f propane monitor and it came without the vent to outside. How can I get a vent? (Maybe kit) The wall is 16 inches thick. Jim Marstaller Naples, Maine

is this a vented or non vented unit? have you checked the rinnai distributorship? call Adirondack Hardware in Keeseville NY. They have parts for Toyostove, Monitors and Rinnai heaters. Their staff are very well versed in all kero and propane heaters.

Rinnai Tankless Water Heater

Question, is there any other equipment that uses propane? You indicate that the problem started after a delivery of propane after running out. If so, I suspect a blockage in either the gas train or the rinnai itself. If tou have the temperature control that regulates the water temperature, you can recall error codes to pinpoint the issue. They are optional equipment so if you can wire one in or ask your propane gas supplier if their service department has one, it will aide in the diagnosis.
