What kind of propane regulator do I need for my RL 94 rannai?

That is a water heater or boiler? You need to contact a gas service contractor. It would be dangerous to do it any other way as the gas pressure needs setting.

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.

Would high winds and rain cause pilot light on a rannai tankless water heater to go out?

High winds can cause reversal of air flow down vent pipe causing pilot flame to blow out.
If situation happens frequently, then special roof cap has to be added.
Have plumber check natural draft up vent pipe.
Other things can cause same problem, for example if vent fan is located in same room as water heater, or house is tightly insulated, and vent fan is ON, then it will draw air down the water heater vent and blow out pilot.

The drum spins but it never gets warm or hot, so it does not dry the clothes.

its probably the problem concerning the heater coil . Please check for connection faults in the heater coil . Thers also a separate fuse for it at the back side fuse box , Also check that proper power input and voltage input is reaching the machine . Thank you . Replace the coil if required .

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.

Rannai 2520

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.

Blow off periodically releases small amt of water.

This may be the case. If you have a check valve installed on the heater to prevent the hot water from backing up into the inlet or cold water side this may happen. A hot water expansion tank at the heater or water hammer devices near the fixture itself should cure the problem.
One question, how high is you water pressure?
