Over time the heater will accumulate "lint" from its surroundings,
a service person should be able to dismantle and clean all areas of the heater and plaques removing the lint and this 95% of the time will fix the problem.
Note: this type of service should be performed at least once every 2 years or sooner depending of the amount of usage.

I have a GloWarm propane/lp gas space heater. Can I use bottled propane tanks?

no you can't, and aren't you worried about carbon monoxide poisoning? Where does the burnt air go?

GloWarm Heaters - ventfree infrared heaters
GloWarm Infrared heaters are residential gas space heaters that are ventfree,
so no venting is required

GloWarm Plaque Infrared heaters direct heat from radiant plaques that
"warm like the sun."

Infrared heaters heat objects in the room before the air,
making them ideal for un-insulated rooms in your home.

All propane heaters require a 100 lb. tank or larger!

If you're referring to one of the ceramic plaques in an infrared heater? Yes, the plaque(s) can be replaced. However, the heater should not be used until the plaque(s) is replaced.

Without knowing what Brand heater you have and the correct Model Number, I have no way to tell you were to find the plaque you need.

My glo warm plaq doesnt glow red but has flame.thanks

The plaque may be out of place or may need replacing, depending on the age of the heater.
Also, although you have flame, make sure you have flame at that plaque that's equal to the other plaques. If you don't the burner may simply need cleaning.

The center ceramic segment does not glow red like the outside ones, it stays more blue, is there a flame adjustment?

No, no flame adjustment, but that section of the burner, behind the plaque may be clogged. If you don't service your heater at least annually or have it serviced annually, more than likely that's the problem. Also, check the condition of the plaque in question. Depending on the age of the heater, it may simply be cracked or worn out.

If you discover it needs replacement you can order one from FMI (the company that bought part of DESA International after the bankrupted) by calling 868-328-6951, then press 2.. You will need to have the Model # & Serial # of your heater when you call.

I have a glo warm gwrn30a a flame shoots over the top of the center plaque about a inch or sol

Check to see that the center (plaque) is seated in its holder securely. Also make sure these (plaques) are clean and there are no obstructions so gas can flow freely thru them. Easy hint for cleaning them is a compressor and blow gun, using pressurized air and blowing them out clean. Try this and it just could solve your problem.

Wont stay lit

If dust gets into the pilot safety device called an ODS (oxygen depletion sensor) then the safety thinks the air is low and kicks the pilot off. To remedy it I flush the pilot with a little rust buster. This cleans the dust out without disturbing the air flap. I have repair photos and a neat demo video that shows how it works HERE

Vent free infared heater

What you are experiencing is common if the plaques are either out of alignment or the burner is dirty. I know you said you cleaned it with low pressure air, but you need at least 120 PS. of air to clean the burner and plaques as per the owners manual.
