Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)

1 Answer

Pilot and Burner shut off at same time at various run times.

After lighting pilot and engaging burner, both will shut off at same time. Some time the house will be heated for only 5 min, sometimes an hour. Pilot relights without problems, blower kicks on shortly after burner heats up unit. Everything seems to be in good working order. I took the blower motor out and cleaned the wheel cage and motor, checked all wiring for loose connections. I am stumped and getting tired of moving space heater room to room. Please help, I have a pet rabbit and i cannot use space heater near him for fear of injuries.Thanks.

Sounds like your pilot saftey is working.the pilot flame heats a device called a thermacoupler which gives a signal to the gas valve letting it know its ok to open main valve. you may need a new thermacouple , might have a dirty pilot orfice or a problem with gas pressure or worse case a cracked heat exchanger in any case in less you have some type of training you should call a pro

Why does burners and pilot forced off after burners are engaged


We get asked this question many times.

If you light your pilot light, hold in the button and then when you release it and the pilot light goes out, generally you need a new thermocouple. Gas repairs can only be undertaken by a qualified gas technician so you can't do this job yourself.

The thermocouple is a safety device that recognises that the pilot has a good flame and is enough to ignite the main burners. The thermocouple open that valve to the burner.

In limited circumstances the thermocouple doesn't need replacing, either the shield that aims the flame to the thermocouple has become dislodged, or the pilot jet is a little blocked by debris. Either way, having the appliance serviced by a qualified gas fitter is the way to go. I am sure you will have seen news stories about explosions caused by gas leaks and faulty appliances.

For (fire) safety, there is usually a thermostat that will turn off the gas if pilot light goes out.

So when you try to light the pilot you will have keep press & hold the pilot gas supply for at least 10 sec until the thermostat is heated up. Then only when the pilot light stays on continually, can you turn on the burner.

Forget about changing to a High pressure regulator!

Small Pilot flame on MrHeater MHBF20lpt & pilot won't stay on.


You will probably need to remove the pilot orifice and clean it out use a small needle or orifice cleaning rod. The pilot flame is not big enough to keep the thermocouple engaged.

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.

I have a PROCOM model ML300TBA, two years old. Here is my problem: Pilot lights fine. Burner lights fine. When I go back the next morning, often times it is out. Burner and pilot are out. It will...


You could try cleaning up the thermocouple with steel wool. Some manufacturers call this a flame generator as well. Any how make sure it is clean and positioned in the top center of the pilot light for best signal. This is only speculation as these are common problems that will arise on heaters in general. This also turns the gas to the burners and pilot light so thats why to start here first. Hope this helps you out.

My pro comp heater will light the pilot but will not light the heater. It just sparks attempting to light, after a while it will shut off completely.


Could be your thermocouple. The spark should light the pilot and the pilot lights the main burner but if the thermocouple doesn't pick up the heat from the pilot the igniter will keep trying to light it until it times out and shuts off to prevent gas buildup.

Pilot light will stay on until the burner shuts off. Seems to blow out the pilot each time the burner shuts off.
