The glass in my fireplace is full of soot - what could be wrong?
Soot will appear on the glass if the combustion temperature is too low or if the lighting period is too short. When lighting the fireplace a lot of air must be supplied to warm up the chimney. Open the riddling grate and the air controls. If necessary, open the door a bit to supply as much air as possible. When the kindling have turned into embers, dry wood is supplied. Plenty of air must still be supplied. Close the riddling grate and primary air supply when the blue/purple flames have disappeared. The combustion is now exclusively controlled by the secondary air controls. Moreover, the combustion temperature is increased by supplying more secondary air and at the same time by keeping the riddling grate and primary air control closed. Besides, wet wood or poor draft conditions might cause sooty glass. Ask your Chimney sweep to measure the draft in your chimney.

How do I remove soot from the door glass?
You can clean the glass using Morsø Glass Cleanser. This must be done when the fireplace is cold. If heavy soot built-ups appear, use treble ammonia water to clean the glass. Soot may appear on the glass if the combustion temperature is too low or if the air controls are used incorrectly. The secondary air controls must be open and the primary air controls closed. The primary air either from the riddling grate or air control are only to be used during the lighting period or when dry wood is put into the fireplace.
