Re-Installing The Glass Door
1. Retrieve the glass door. Visually inspect the gasket on the backside
of the frame. Gasket surface must be clean, free of irregularities and
seated firmly.
2. Position the door in front of the firebox opening with the bottom of
the door held away from the fireplace. Hook the top flange of the door
frame over the top of the firebox frame.
3. Let the bottom of the door frame swing gently in towards the fireplace
ensuring that the gasket seats evenly as the door frame draws shut.
Fasten the two latches located underneath the firebox floor to the door's
vee-flange. Close both the latches securely.
4. Turn on the gas. Restore electrical power.
