Hello. I fire it up. It runs one minute and shuts off. Piolet and all. I start it up. Runds 5 min and same thing.
Here's the problem. The Oxygen Depletion Sensor (ODS) which is part of the Pilot is clogged with dust, lint and/or pet hair. When that happens, the ODS sensor reads the oxygen level as unsafe for operation and shuts the unit down, by closing the gas control valve. This problem occurs quite often when the heater doesn't receive Annual Maintenance and Service.
To solve this problem yourself. You will need to dismantle (remove) the front part of the heater, carefully remove the log set and you will be able to access all of the interior workings that need to be cleaned. A Shop Vac with a brush attachment and a can of compressed air with a straw nozzle (like you clean your computer with) works well in completing the clean process. Be sure to vacuum all of the interior of the firebox, as well as the burner(s). Be sure to clean/vacuum thoroughly. While you have the logs out, vacuum them on all sides. To clean the pilot, use the can of compressed air with the straw nozzle attached and blowout the pilot tip with a quick blast of air. Look down the pilot from the tip (where the flame comes out) and about 2/3rd's of the way down, you will see a small hole in the side of the pilot. That's the ODS Sensor. Place the tip of the straw nozzle just barely into that hole and give it a quick blast of air. You will probably see debris blow out the other side. Once you have completed all of this, start to reassemble the heater. Be sure to install the logs identically to the way they were original installed. Failure to do this correctly, will cause sooting problems. If in doubt, consult your Owners Manual. Once you have completed reassembling the heater, light the pilot. Be sure to hold the Pilot Control Knob in for one minute, before releasing it and turning it to ON. If everything now works as it should, pat yourself on the back, As you just completed what's called "Annual Maintenance". This should be done every Fall, before firing the heater up for the season. If you have house pets, you should do this twice a season. First in the Fall and again in mid-January.
If all of the above did not solve the problem, the Thermocouple, which is part of the Pilot Assembly has started to fail and needs to be replaced.
Hope this helped you solve the problem. Please let me know and be sure to rate my response to you. Thanks!
