Close the door and fasten it with the door securing
nuts, open it and check the impression of the sealing
grooves in the braiding. There should be a uniform
impression approximately 2mm in depth. Adjust by
means of the fixing nuts to obtain the required
impression. Tighten the fixing nuts and the door
securing nuts diagonally – as you would when
tightening the nuts on a car wheel. This is important
as it ensures an even and adequate seal between
the door and front section. Make sure all locknuts are
fully tightened and forming an adequate seal
between the door and combustion chamber.
