Question about Rinnai Desa Vent-Free Infrared Gas Heater: Vent-Free Infrared Gas Heater(18,000 BTU)

Pilot goes out after heating cycle

Rinnai model # REH-30DT-P, propane.

I can get the pilot lit, set the heat level, and the burner will ignite heat up and reach the heating level set. When the burner shuts down the pilot will diminish and go out, if I try to relight the pilot it will diminish and go out, after holding it down to allow the sensor to heat up, when I turn the dial to a setting. I have to wait until the heater cools off to light the pilot and have it remain on again, then once the burner cycles it does the diminish and go out thing again.

    Seems no one on the net can answer the question. It's gotta be a clear cut answer to such definate symptoms. Your description of problem is my EXACT problem also.

    I also have the same problem.  I sat and watched the cylcle to see when the pilot was actually going out.  After becoming impatient, I decided to turn down the thermostat to make the cycle stop sooner.  While still in the warm range the pilot would stay lit.  after the water got a bit hotter (top of the warm range) the burner turned off and the pilot seemed to slowly extinguish.  I was expecting to see it being blown out by the burner shutting off but that didn't appear to be the case.  I cannot re-light the pilot until the water has cooled.  I have replaced the Thermo-coupler.

Check regulator on the unit.
Check pilot unit on the heater
use soapy water to check for leaks if see bubbles turn off main gas supply valve.
always turn off gas supply before any checks or repairs are made
when all else failes call your local gas provider to check heater and gas supply

When I try to use my Thermolaire model SU402E, the pilot lights( and stays lit), but the main burner will NOT ignite.. any suggestions as to what could cause this if the pilot stays lit?


Bad igniter? When you 1st try it the gas valve will give enough gas that you would get the burner lit if the igniter was glowing red. If you're desperate you can light the igniter area w/ an aim n flame, but you definitely want to do that w/ caution and crank up your t-stat so the furnace stays on awhile Cuz you'll have to do it again for heat or buy an igniter($40 or so)

My Delonghi Propane Heater will not stay lit.

RHFE Rinnai 551FT gas heater is not working after 7 years


see this steps and fix it. God bless you
.
If there is no heat, check the electrical service panel for a burned fuse or tripped breaker. Relight the pilot light (see below).
If there is not enough heat, adjust the burner air shutter (see below); and clean the burner ports (see below).
If the pilot light does not light or does not stay lit, clean the pilot orifice carefully with a toothpick, test the thermocouple and replace it if it is faulty (see below).
If the flame flickers, adjust the pilot (see below).
If there is an exploding sound when the burner ignites, adjust the pilot to a higher setting and clean the pilot orifice and the burner ports.
If the burner takes more than a few seconds to ignite, clean the pilot orifice and adjust the pilot light.
If the burner flame is uneven, clean the burner ports. If the burner flame is very yellow, clean the burner; open vents in the furnace room to provide more air; adjust the burner air shutter.
To light the pilot on a standing-pilot (always on) ignition system, follow the lighting instructions located near the control. Otherwise, try these steps:
Light the pilot:
  1. gasfurnace1.jpg Press and hold the pilot control knob to start the pilot. Set the control knob to the pilot position. Hold a long match under the pilot gas port.
  2. Press the control knob; the pilot should light. Hold the control knob down until the flame is burning brightly (about 30 seconds). Release pressure on the knob, and turn it to the on position.
  3. If the pilot goes out when you release the control knob, try relighting, holding the control knob down longer. If the pilot again goes out, check the thermocouple (below).
Adjust the pilot:
  1. Remove any cap covering the pilot adjusting screw on a combination control.
  2. Turn the adjusting screw counterclockwise to increase the flame or clockwise to decrease it. It is correctly adjusted when the flame envelops the thermocouple bulb by 1/2 inch and appears dark blue with a small yellow tip.
Test and replace a thermocouple:
  1. Hold the control knob to pilot and light the pilot as above.
  2. Unscrew the thermocouple fitting with an open-ended wrench.
  3. Set a multimeter to the DVC (lowest voltage) scale.
  4. Clip one multimeter lead to the end of the thermocouple tube nearest the pilot and the other lead to the fitting on the other end of the tube.
  5. If the multimeter shows a reading besides zero, the thermocouple is functioning. Replace the thermocouple tube.
  6. If there is no reading, you will need to clean or replace the thermocouple following steps 7 through 11.
  7. Release the control knob and shut off the main gas valve on the gas-supply pipe that leads into the burner. Shut off power to the burner at the electrical service panel .
  8. Remove the thermocouple from its mounting bracket.
  9. Wipe the combination control clean and install a new thermocouple, tightening it by hand, then give it a one-quarter turn with a wrench.
  10. Insert the thermocouple into the pilot bracket, being careful to not crimp the tubing.
  11. Turn on power to the furnace and relight the pilot (above).
Adjust an adjustable burner air shutter:
  1. Set the thermostat to its highest setting to keep the burner running. Once the furnace has heated up, remove the burner access panel and loosen the locking screw.
  2. Open the shutter by turning it to the right until the blue base of the flame appears to lift slightly from the burner port surface. Then close the shutter until the flame reseats itself on the surface.
Clean removable burner tubes and ports:
  1. Shut off gas and power to the furnace.
  2. Unscrew or loosen and remove the tubes from the supporting bracket.
  3. Carefully clean the tubes with a brush or vacuum, making sure not to damage the burner ports.
  4. Use a stiff wire to clear any debris from clogged ports.

Propane heater goes out after heat cycle


I've seen excessive draft draw the pilot flame away from the thermo couple when the burners light so when the burners shut down so does the pilot.

Pilot light keeps going out


Dan, Since you just had the tank filled and the heatewr installed a tinty piece of trash could have entered the pilot orfice. Un do the lower floor panel take off the pilot assy. Blow out the small pilot orfice. Blow reverse from normal gas flow to unlodge the debre. Re asemble and light.
If this dosen't work It may be the pilot air intake is too open causing the pilot to blow itself out.If thats the case close off the air adjustment some. It will be located behind where the flame exits the pilot orfice.
