The hinge side is secured by a parallel hinge system allowing the door to move away from the
front face of the boiler when turning the hinge nuts B anti-clockwise, but still secures the door to
the hinge pin.
The swivel bolts A on the latching side can be moved out of their securing slots once the nuts are
undone. In order to seal the door fully around the circumference, it is important to ensure the door

just the two on the latching side.
The door seal utilises a 25 mm x 35 mm square section glass rope which is glued into an angle
section welded into the perimeter of the door. Over a period of time the glass rope will lose its
