Door Seal Testing and Adjustment
Without a good sound airtight seal around the door the stove will not work
as designed and will lead to the glass blackening and a loss of control.
Over time the rope seal compresses and the seal between the door and the
fire cube is compromised resulting in the need to replace the rope.
Testing the door seal
With the stove cold take a piece of paper, open the door and place the
paper between the door and the stove. Close the door. The paper should
be trapped between the door and the fire cube. There should be some
resistance when pulling the paper out. This should be done on all four sides
of the door.
Adjusting the door
Where the paper is not trapped the door needs to be adjusted. If the
adjustment needs to be made on the handle side of the stove, wind or
unwind the handle one complete turn and retest. For appliances that have
a restricted 90 degree handle, release the grub screw on the side of the
door boss (figure 4) to allow the mechanism to turn fully. Replace after
adjustment. If the handle does not line up with the door simply screw the
grub screw in or out until it does.
Figure 4
For adjustments on the hinge side of the stove the door must be removed.
Lift the top off the stove, twist and rest on the fire cube. Open the door
(Shoreditch, Shipton, Salisbury and Beaumont models) and lift from the
hinge pins.
Loosen the grub screws under the hinge pins, rotate hinge pin in clockwise
direction to reduce the gap between the door and fire cube, anticlockwise
to increase the gap. Replace door and check seal before tightening grub
screws.
