Keeping your Stove Glass Clear
To maintain clear glass there are 2 factors.
1. Correct and dry fuel
(see Principles of combustion, section 4)
2. Correct use of air controls
(see Making a fire - wood/solid fuel, section 4)
As a general rule the hotter the fire the clearer the glass will be. If you have wet fuel
the fire will struggle to reach high temperatures, an inefficient burn = blackening. If not
enough air is being drawn through the firebox, due to incorrect use of the controls, the
fire will slumber and not burn as well or efficiently also leading to blackening.
However there are also times within both the burn cycle and areas within the physical
firebox where the temperatures are cooler. As far as the burn cycle you can just wait
for a hotter fire and any discolouration will burn off. Cooler spots in the fire box such
as in front of the fuel retaining bar and the corners of the glass can show signs of
discolouration after a number of fires. This is easily dealt with. When the stove is cool
either use an off the shelf stove glass cleaner or dip a damp cloth/piece of kitchen roll
in wood ash and rub the area. Any persistant areas can be cleaned with wire wool.

Door Seal
If the door seal shows signs of deterioration, you may need to replace it. 14mm
diameter rope is required for fire doors, 10mm for oven doors. To test the effectiveness
of the seal, when the stove is cold, trap a piece of paper between the door seal and
stove body shutting the door completely, you should feel resistance when you try to
pull the paper out. Repeat this for each edge.

Door Glass Replacement
FIRE DOOR:
Remove the 4 or 6 stainless steel
screws retaining the double glazed glass panel.
This panel is two pieces of glass with a 2mm x
10mm seal between them. Replace the 2mm x
10mm seal if necessary. Position replacement
glass and fit retaining channels, tighten screws
just enough to pinch the glass. Overtightening
can result in the glass cracking.
OVEN DOOR:
The oven door is single glazed and
held in place with tabs. 2mm x 10mm seal is used
between the door and the glass.
