Hold the Red Button for much longer than you think. It has to fully heat the thermocouple safety device. Then release VERY slowly. There are tips here

Check the thermocouple

Clean pilot first if this does not work it could be your thermocouple also check gas in tank

I have a table top heater and was wondering why I have flame shooting out of the top of it when I should have like a blue flame, what can I do

The thermocouple is bad. That is the part right next to the pilot light that sense's the flame and hold the gas valve open to the pilot. Take the old thermocouple off and go to hard ware store and get a 18" one of what ever length you need and replace. 5 dollar part.

I called Nexgrill technical support at 1-800-913-8999. They are sending me a new thermo couple to keep the valve open when ignited - so the patio heater will stay on. I needed to give them the serial number (inside the propane tank door) and fax them a copy of the receipt.

Hope this helps.

There must be a blockage in the hose and regulator or your large tank may be checking and not allowing the unit to stay lit. Remove the large bottle. Let the gas line equalize for about 30 seconds and then reattach the bottle. Very slowly, open the knob on the large tank and I mean very slowly. Did I say open it slowly. The new OPD propane tanks often have a very touchie excess control valve that won't allow enough gas through if opened too rapidly. Now tray and light the heater. If you still experience the same, get a technician involved so they can inspect the gas pressure.
