My gas fireplace shuts off after burning about five minutes - both main burner and pilot shut off.

Most fire place burners have an oxygen depletion sensor on them nowadays. If you can restart it after a while, a few minutes or so, and shuts off, it is probably the oxygen sensor. The owner lights fireplace and shuts the door, and the fire depletes the available oxygen and the fire will start producing copious amounts of CO which is a hazard. Most fireplaces have a fresh air supply available to provide combustion air but needs to be opened for the fireplace to work properly. Check the manufactures recommendation as to the proper installation of the fireplace furnace.
Hope this helps

We have a Rinnai REH-15F-2A natural gas heater (approx 15 yrs old). it has just started going out, it doesn't leak gas. is this something repairable or beyond repair? thanks tameka

Tameka, what you described sounds like the Thermocouple or Thermopile is failing. If your heater is a Flue-less heater, the Oxygen Depletion Sensor (ODS) which is part of the Pilot assembly, may simply need cleaning. Any of the causes I listed are repairable and would require a service technician to do it.

Hope this helped you. Please let me know.

I have a everdure 6 burner gas heater. its pretty old and works sometimes. the problem is that it take a while to turn on and once it started it just turns its self off with in minutes. this happens...

Your flue-less gas heater may simply need a a good interior cleaning and servicing. From what you described it sounds like the Oxygen Depletion Sensor (ODS) may be clogged with dust, lint etc. The ODS is part of the pilot assembly and constantly reads the oxygen level in the room, when the heater is in use.If the oxygen level drops to 25% the ODS shuts the unit OFF by closing the gas valve. This can occur if the ODS is dirty, because it's falsely reading the oxygen level.

One other thing that can mimic this problem is a faulty Thermocouple. With age, they wear out. It's also a safety feature that controls the gas flow to the pilot.

Everything I have mentioned is repairable. But, if you want to make it a DIY project, it will require some dismantling of the heater cabinet to access everything and replace parts. If the heater is as you say "pretty old", you may want to consider buying a new heater. Sometimes, it's just not worth the time and effort to repair an old heater.

Hope this helped you to troubleshoot and solve the problem.

I replaced the thermalpile in my wall heater and when I turn the stat up the pilot goes out what do I do

The air intakes of the burner may be clogged or you wired the "thermopile" to the wrong contacts on the control valve.

You didn't mention if this was a vented or vent-free heater. If it's a vent-free heater the same things listed above still apply. However, it may be that the Oxygen Depletion Sensor (ODS) which is part of the pilot may be clogged with dust, lint and/or pet hair. When the T-stat calls for gas to light the burners, the ODS senses there's not enough oxygen for safe combustion and closes the gas valve.

Also, gas pressure to the heater may be low. Only enough to keep the pilot burning, but not enough to ignite the burner(s).

Hoe this helps to head you in the right direction on further trouble shooting the problem.

The unit will light however after a few minutes of running the heater shuts off and does not continue to heat

Does this unit have an OXYGEN DEPLETION SENSOR ? if so, then are you using the heater in an area that is too confined or too closed-up? You say it is forced air, therefore the air must move continuously or the over-heat sensor will stop the gas since there is no air to remove the heat being produced. If this unit has a thermocouple flame sensor, the flame my not be touching thethermocouple sufficiently and the thermocouple thinks something is wrong and stops the gas. Or the thermocouple can be weak and not give a strong signal to allow the gas valve to stay open. This is common on heater and hot water heaters, and you simply change the thermocouple.
Good Luck, Macgivor

Pilotlight will not light, getting spark, but no propane.

make sure you have the gas valve knob on turned to pilot while pressing that down while pushing the spark it should light or it is tripped on a safety like rollout switch or oxygen depletion sensor if equipped which all ventless heaters are

Glo warm heater

These are vent-free heaters and use an oxygen-depletion sensor to shut a unit off if there is not a sufficient amount of oxygen available for combustion. It is either doing it's job and you may have to open or crack a window while it's operating.
