I have owned my ProCom MTB300TBA for more than 5 years without any problems other than cleaning the ignitor by using a compressed gas electronics duster. This is usually necessary when dust accumulates around the pilot which extinguishes the flame preventing the unit from igniting the burner. In addition to this I've noticed that the central part of the burner after lighting surges directly in front of the pilot light causes the flame to reach higher towards the top of the inside of the unit. Which didn't occur at all during the first few years of the units' winter operations. Is this behavior due to a loose connection of the coupler connection to the burner? This hasn't created any reason for concern other than wondering if the burner and the pilot need adjustment, replacement or anything else you might know of that I should have knowledge of. If a picture of the unit while in operation would be helpful, please advise. Thank you in advance for any information you can provide or inform me about which will increase the efficiency, safety and the operation of the unit. Thank you, Richard

I purchased a Procom 20,000 BTU Vent Free Propane Heater. After it was installed, it produced yellow-tipped flames, primarily when working in low mode. I contacted my propane supplier, and they sent a technician who installed a new regulator on my supply tank and adjusted the pressure between 12 to 14. It continued to produce yellow-tipped flames, and emitted an odor. I checked the air supply to the room and it has very good ventilation. The humidity level stays below 30%. I contacted ProCom customer service and described this situation, and they decided to replace the unit, which was purchased from Home Depot. I received and installed the replacement unit, and it is producing yellow-tipped flames, and an odor, exactly the same as the first unit that I purchased. Today, I had a technician from the propane company inspect the tank and regulator, and they confirmed that the pressure was between 12 to 14. The technician told me that the issue is not related to pressure, since he varied the pressure and inspected the unit during the process, and the yellow-tipped flames and odor persisted. Please advise. Sincerely, Mike Krumrine
