Basically, the primary air is used to start the fire, and the secondary air is used to maintain
the fire.
The RAIS 60 Insert stoves are equipped with an air control handle on the right of the door
near the bottom. When the handle is pushed all the way up to Position 1, the primary air
and secondary air are both fully open.
When the handle is pushed down about half way to Position 2, the stove gets only the full
secondary air, and if the handle is pushed down further toward Position 0, the air supply is
reduced. At Position 0 (down all the way), the stove will shut down.
Firewood used should be seasoned, split wood with an adequate low degree of moisture
(15 - 22%), and ideally about up to 20” (50cm) in length. 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.
Push the air control handle up to Position 1. 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 push the air control handle
down to Position 2. Use the door handle cover over the handle.
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.
The RAIS 60 Insert was developed to an optimal thermal output of 23,900 BTU/hr (7 kW)
with a water content of 18%, which corresponds to about 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, move the air control handle up.
