My heat wont stay on

[chipsta71]

I have a new Gibson AC/Gas heat unit. The AC part works fine, but the heat side wont. What is happening is when I set my themostat to heat, it is signaling the unit to turn on and the flame then ignites, when the fan turns on the flame goes out. Can someone please help?

Call a service company.

As said call for service. When was the last time it was checked? Should be serviced every season anyway.
