Will this work with heatilator fireplace model gcdc60?

Yes, this pilot assembly will work with your model GCDC60

I have a heatilator fireplace model gndc30e, serial # ga 966710. it won't start light after turn on wall switch. does this assembly fit ?

No - this will not work. Please call 800.852.1224 & ask for Aaron. He can help find the corrrect pilot assmebly.

does this work for HEAT N GLO ST-HVB-IPI ?

This Type of pilot/generator comes in a number of configurations. As far as what it fits, I do not know. Best Advice is make SURE ! that it is EXACTLY like the one you have on your fireplace and FOR SURE WHAT GAS it uses !
