This may mean that the plaques are cracked, if they are cracked you cannot repair them, you would just have to replace them. You can contact Master Parts they may be able to help you. You can contact them toll free at 800-446-1446. Thank you

Why does the heater turn off?

If it's thermostatically controlled, if shuts off the burner when it reaches the set temperature. Is the pilot flame going out too? These heaters require a certain amount of fresh air to operate properly. If the oxygen level gets too low, it is designed to shut off completely for your safety.

After all 5 burners ignite, one of either outside burners will flash out and blu flame licks upward.

If you have 'inshot' burners or the standard old 'ribbon' burners, there could be little wings on the sides of the burners that are responsible for spreading the flame from the igniters location to the burner next to it. I would think the two outside burners need to be 'tweaked' a tad bit either clockwise or counterclockwise to align better the little 'flame-spreader' wings. Some older ones ignite the burners by use of a 'zip-tube' which carries the igniting flame across the top of the row of burners to light them in a 'blanket' pattern. This style was typically the old 'atmospheric' burners and not the ones with combustion air fans.

How can I adjust the flame? I have the CGCFTP and one side of the flame is higher (alot) than the other side. It's burning the top of the metal insert.

Normally, you can raise and lower the flame height, with the Control Knob (Wider the white stripe the higher the flames. Narrower the stripe, the lower the flames). But, I don't think that's your problem. From your description, it sounds like the burner may be clogged or there is a air shutter control problem on the open end of the burner. This controls the air to gas ratio. Also, depending on the age of this Compact Classic Firebox and whether or not annual maintenance was preformed regularly, the burner may be shot entirely. Since DESA International, who made the Comfort Glow line for Lowe's, went out of business in 1999, we know the heater is at least 2 years old, minimum. Although, I suspect yours is an older model, based on the Model Number you provided. If you feel comfortable troubleshooting it yourself, I have provided a link to your Owner's Manual, in case you have misplaced yours. You can down load and print it for future, as well as for any parts you may need.

If you don't feel comfortable repairing it yourself, contact your propane provider. As most propane providers also do service and repair for this type of Vent-free Gas Fireplace.

Hope this helped to steer you in the right direction.

My heater lights but the flame is blue on the bottom and a yellowish white about 2 inches after. Why is it not all blue. This set to natural gas.

This could be caused by an improper gas to air mixture. Generally, it's an indication the air indicate valve is clogged with dust or lint. The air intake valve is part of he burner, It can be seen as an opening where the gas line from the control valve attaches to or enters the burner.

Turn the heater off and remove the front cover. This will give you access to all the inner workings of the heater. Using a vacuum cleaner that has a hose and crevice tool attachment, vacuum the burner(s) and the air intake valve I described above. While you're at it, clean all of the interior of the heater ( a brush attachment works well for this). Blowout the pilot tip with canned compressed air that has a straw nozzle (like you clean your computer with). Reassemble the heater cabinet and light the pilot, then the burner(s). Do the flames appear to be blue with yellow tips? If so, you've solved the problem and also, what's called "Annual Maintenance". Which normally is done in the Fall, before firing up the heater for the Winter. Do this every year and you should have years of trouble free service from your heater.

Let me know if this solved your problem.

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.
