Can I use gas logs (just the logs parts) from a vented gas fireplace on my ventless system??

I bought a Ventless gas logs set with burner and remote on Ebay, when I recieved it the logs were broken into pieces due to the fact that the person did not pack it properly ( I am trying to get a refund), Can i use the logs (just the logs not the burner) from the vented gas logs I had in my fireplace with the new Ventless burner i bought??
