Question about Procom QL300TYLA Heater

1 Answer

Just turns off?

We recently bought a home, and it has a procom heater in it. However, when we try to start it, it will run for a while and then just turn off. It isn't the ODS in operation, as we have always had plenty of fresh air in the house, even going as far as to open windows and doors when running the heater. What is the problem?

Re: Just turns off?

From my memory, this is an unvented model. The ODS could be bad and turning off the unit or you could be experiencing a bad thermocouple. If there is any way to temporarly bypass the ODS, I would try this first. Do not run this unit unattended. If the unit stays on when the ODS is bypassed, you found your problem. If not, change out the thermocouple. It is a small diameter copper probe that goes from the gas valve up to the pilot light. Good Luck.

Hello, I just bought the PROCOM MD300TGA Garage heater.I did'nt receive any paper work with the unit regarding what size propane line to run to it.I would guess it to be either 3/8 or 1/2.What do you...

Depending on the run of gas line required, most area building codes require a minimum of a 1/2". However, the last 6' can be 3/8".

Also, you can download the Owners Manual from the ProCom Website or from the World Marketing website.

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.

Heater will not stay lit on auto procom ml 300 blue flame

If you have an ML300HGA, it is a manual-control heater, which means you turn it on and you turn it off. No thermostat. It does not have an AUTO setting.

Likewise, the thermostat-controlled models do not have a Manual mode. If you have the ML300TBA, it has a thermostat and will turn itself on/off in order to maintain a room temperature.

On manual models, the numbers (if any) on the dial are heat output selections. Set the control to the highest heat setting and that's what it does until you turn it off.

On automatic thermostat models, the numbers on the dial are temperature selections. Set the control to the highest heat setting and the heater will continue running until it is 85-90 degrees, then shut off. Set it around 2 and it will maintain a temp of around 70 degrees.

All Procom heaters are either automatic (thermostat-controlled) or Manual. None are both.

The QL300 has a range of 20,000 to 30,000 btus. That shouldn't be too big for your 300 square foot room with high ceilings and a loft. It has a thermostat, so it will shut off when the room gets warm. 1 pound of propane contains about 21,000 btus, so you will be burning 1 to 1.5 pounds each hour that the stove is running.
