20 Most Recent Rinnai RHFE-1004FA 38,400 BTU Energy Saver Ductless Heater - Natural Gas Questions & Answers


Hi This is happening to us and I called Rinnai... they suggested that if anyone either in our apartment or an ajoining one has painted walls or varnished a floor that the convection heater picks up the smell and the only way to get rid of it is to burn it off by running the heater for several hours in a well ventalated room...

I am going to try it tomorrow.

will let you know

check the temperature control bulb that is located on the rear of the unit at the bottom near the power cord comes out of the unit. a thin gray wire maybe three feet long at the end is located the little glass black bulb. you will have to place this bulb where it can monitor the room temperature. if it is to close to the heater it will cut of whit out heating the room and keep coming on. like wise if to far way or in an area that is to cold then it will keep running. you will have find the right placement for the sensor bulb. it may take a little time.

Sand off all the corrosion to bare metal. Use a metal etch to scrub it down (any phosphoric acid will do), this can be gotten at Home depot or any home center in the paint section (also know as naval jelly). Clean the area with clean water after applying the acid and let dry. The naval jelly will leave a slight coating after the rinsing and this will prevent rusting afterward. Prime the metal with automotive primer, 2 or 3 coats will do. Let each coat dry completely. Use an epoxy paint (I've used single stage polyurethane and 2 part mixable epoxy type). The 2 part mixable epoxy is more expensive but lasts indefinitely and gets very hard). McMaster-Carr Supply has these products and they can be ordered on line. Apply the paint, let it dry according to the manufacturers directions and you shouldn't have any problems.

If its not producing heat, yep! If it is, it indicates that there is an error code stored in memory.

Water heaters are the part of every home in America. The one of the most common reason of that problem is your lithium battery you have used is outdated. Follow these steps to check the problem.

Closed the valve of gas from back end.
open the water heater cover
Replace lithium battery with new one
Screw in the water heater
Check it
Now it will start
