Morso 7670 Installation And Operating Instructions Manual page 14

Do not for any reason attempt to increase the firing of your heater by altering the air control
adjustment range outlined in these directions.
Warning: Fireplace stoves must never be left unattended with the door open.
If the door is left partly open, gas and flame may be drawn out of the fireplace stove
opening, creating risks from both fire and smoke. We recommend that you fit a smoke
detector in the room where the stove is installed.
DO NOT OVERFIRE THIS HEATER. Overfiring may cause a house fire, or can result in
permanent damage to the stove. If any part of the stove glows, you are overfiring.
The maximum recommended weight of wood fuel per load is 2.0 kg/h/4.0Ibs (approx 3 split logs).
Under normal firing, the average flue temperature in the stove pipe, measured 20 cm above
the stove, is approx. 300° C (550°F). The maximum flue temperature in the stove pipe must not
exceed 450° C (750°F). If the flue temperature exceeds 450°C (750°F), it is considered as over
firing and may cause premature wear and tear of the stove.
To help gauge the correct running temperature of your stove, we recommend you use the Morsø
Flue Gas Thermometer (part # 62901200). The Flue Gas Thermometer magnetically attaches
onto the stove pipe approx 20 cm (8") above the stove's top plate and measures the surface
temperature of the stove pipe. Please see your authorized Morsø Dealer for availability.
Draft conditions
If smoke or fumes come out of your stove when lightning up and reloading, or if the fire simply
will not respond, a poor draft is almost certainly to blame. (In a very few cases, there may be
insufficient fresh air getting into the room - see installation advice above). Take advice from your
stove supplier on how best to upgrade your flue system to improve draft.
Rules of woodburning
If you want less heat, put fewer logs on the stove and reduce the amount of air. It is still important
to maintain a good layer of embers.
Less heat - less wood - less air
Greater heat - more wood - more air
Soot deposits will settle on the glass if the stove is run too slowly or if your wood is
not well seasoned.
We would strongly recommend that you do not leave your stove alit at night. It harms the envi-
ronment, and constitutes very poor use of the wood, as the gases in the wood do not ignite at
the low temperature, but settle as soot (unburned gases) in the chimney and stove instead.
