You may have a bad thermocouple. This is a device that when it gets hot (usually from the pilot light) enough it sends a signal (allows conductivity) which allows the heater to stay lit when switched into the 'heat' or functional mode.
It's a common safety element in all gas furnaces and stoves to ensure that the pilot says lit and no gas can escape in case it somehow extinguishes.

You might have a bad heat exchanger

Check out the thermocouple .

The pilot thermocouple is most likely defective, replace it, they are very cheap to buy. Check with a local appliance repair for the part.

I believe all the Empire manuals are there to download or read at their website: EmpireComfort.com.

the pilot oriface is blocked it needs cleaning out ,

flame sensor,just take some fine sand and lightly sand,it will be where the flame hits one of the burners,should look like a probe,if this helps please give me a fix ya
