In the past I have replaced the ignition battery a couple of times when it needed doing but never had a problem removing the front cover of the gas fire (pull towards at the top and lift up), this weekend on site it was wet and chilly so I went to turn on the fire and no ignition, I then continued to remove the front cover and it would not budge and I could not find much info from the Truma leaflet, I then found a post on my phone saying someone had the same problem but found a phillips headed screw centrally situated behind the top grill, this I removed and the front came away, hope this might help someone out there who thinks their front cover will not come away,
