Question about Procom MN100TBA Heater
The problem is the pilot assembly needs cleaning. This means cleaning the tip and the Oxygen Depletion Sensor (ODS). You will need to turn the gas off and remove the front of the heater's cabinet. Once you do, you'll have access to all the inner workings. Plus, you'll proabaly find a lot of dust and lint inside the heater cabinet. A shop Vac with a hose, brush and crevice tool attachments works well for cleaning all the interior of the unit (Cabinet interior, burner(s), etc). To clean the Pilot Assembly, use a can of compressed air with a straw nozzle ( Like you lean your computer with). Place the straw nozzle just barely into the tip of the pilot and give it a quick shot of air. Look down the pilot from the tip and you will see a small hole in the side of the pilot. That's the ODS sensor. Place the straw nozzle just barely into the hole and give it a quick shot of air. You'll probably see debris blow out the other side. Once you have completed all of this, reassemble the heater, turn the gas line valve back on and light the pilot as you normally would. It may not light the first try or two, because there may be some air in the gas line. Once the pilot lights, hold the Control Knob in for One Minute, then slowly release it and the pilot should remain lit. Turn the control knob to ON and the Burner(s) should light and burn as they should.
If all the above worked, congratulate yourself, you just completed what's called "Annual Maintenance". Which should be done every year, in the Fall, before you fire the heater up for the heating season.
