The handle on the right side just below the door controls the shaker grate. It simplifies the
cleaning of the stove. You just shake the ashes through the grate into the ash pan.
Refer to Removing the Ashes in the CARE AND MAINTENANCE Section of the
Manual for detailed directions.
Firewood used should be seasoned, split wood with an adequate low degree of moisture
(15 - 22%), and ideally about 12 - 14” (30 - 36cm) in length and for the RAIS 86, 10 - 12”
(25 - 30cm). In order to get “dry wood”, it should be stored in a dry place under a roof with
sufficient fresh airflow for at least one full year for softer woods and a minimum of two
years for hardwoods.
Only use the wood fuel as described in the FIREWOOD Section of this manual!
Building the Fire
To start the fire lay a few pieces of kindling or dry twigs and paper at the back of the
firebox (enough for a small fire). Build the wood directly on the stove hearth, and do
not use a grate or elevate the fire.
Set the air control to Position 1. On the RAIS 4 and RAIS 106, open the baffle plate (lift the
handle on the right to a vertical position). Also, a smoke plate located at the top in the
firebox can be pulled forward to help the smoke exit faster. Use the smoke plate hook to
move and adjust the smoke plate. Light the fire, and during start up you can leave the door
slightly cracked (with supervision) until the kindling is burning well.
Add 1 or 2 split logs on the kindling fire and allow enough time for them to catch on fire
(about 2 - 5 minutes). Now close the door completely, and set the air control to Position 2.
Further adjustments to the air control may be made later on if necessary. Never reduce
the air intake to Position 0 while logs are still burning. This will cause incomplete
combustion (creosote), risk of explosion, and soot on the glass. Once the door is
closed and burning correctly, the stove does not require supervision. Adjust the baffle plate
to horizontal and push back the smoke plate.
The RAIS Classic Series was developed to an optimal thermal output of 20,500-27,300
BTU/hr (6-8 kW) with a water content of 18%, which corresponds to about 4-4½ lbs
wood/hour. If the fire is fed more than recommended, there is a danger that the stove will
be overloaded and might discolor. Over firing is unnecessary and will void the
warranty.
Check for a Proper Burn
For a proper burn, the inside of the firebox and the glass panel should be free of soot, and
the ashes in the bottom should be light gray (not black). To allow more air in to the heating
chamber, open up the air controls (handle/vents to the right).
For normal operation the air control should be set at Position 2. However, if the wood is
burning too quickly, you can adjust the air control (handle/vents toward the left).
