Flavel Firenza Gas Fire

[colchester]

My 2yr old grand-daughter decided to post her Christmas Card through the gap at the top of the fire
I cannot see any screws to release the cover enough to retrieve this card
Loathe to use the fire incase the Card/envelope with catch fire
Any help locating the cover release screws

do not use the fire, needs dismantling and card removing, could be a good time to get it serviced and safety tested
