affect the extraction of flue gases from the wood 
insert. Check the combustion air supply (if required, 
open the cover flap)!
3. Adjust the combustion air regulator to the far right, 
and open the firebox door (swing open).
4. Place chopped wood into the middle of the firebox 
using the funeral pyre method (use softwood).
Caution: The height of the wood pile must not exceed 
the lower marking on the deflector plate!
5. Place standard firelighter cubes under
the wood pyre to help start the fire. (paper is not rec-
ommended because it burns too quickly and causes 
ash to circulate).
6. Never use methylated spirits, petrol, oil or other 
easily combustible liquids.
7. Light the fire using the firelighter cubes and, if 
required, leave the firebox door open by approx. 3-5 
cm. The fire should now light, burning
brightly and intensively.
8. When the kindling wood is burning well, add smaller 
hardwood logs or larger softwood logs using the 
funeral pyre method and close the door.
9. When the wooden logs are burning well, the air con-
trol lever can be set to a position in the middle.
10. You can find out more about the correct volume of 
wood to add to the fire in the section ‘‘Volume of wood 
to add per hour’’.
Lighting the fire in your masonry insert is very easy if 
you follow the instructions given below:
1. A fire may only be started in the masonry insert 
when the firebox lining has been correctly installed.
2. Turn off any air extraction ventilation (kitchen, bath-
room, WC etc.). This will avoid low pressure building 
up in the installation room that can
affect the extraction of flue gases from the wood 
insert. Check the combustion air supply (if required, 
open the cover flap)!
3. Adjust the combustion air regulator to the far right, 
and open the firebox door (swing open).
4. Place chopped wood into the middle of the firebox 
using the funeral pyre method (use softwood).
Caution: The height of the wood pile must not exceed 
the lower marking on the deflector plate!
5. Place standard firelighter cubes under

the wood pyre to help start the fire. (paper is not rec-
ommended because it burns too quickly and causes 
ash to circulate).
6. Never use methylated spirits, petrol, oil or other 
easily combustible liquids.
7. Light the fire using the firelighter cubes and, if 
required, leave the firebox door open by approx. 3-5 
cm. The fire should now light, burning
brightly and intensively.
8. When the kindling wood is burning well, add smaller 
hardwood logs or larger softwood logs using the 
funeral pyre method and close the door.
9. When the wooden logs are burning well, the air con-
trol lever can be set to a position in the middle.
10. You can find out more about the correct volume of 
wood to add to the fire in the section ‘‘Volume of wood 
to add per hour’’.
11. When the wood has been completely burnt and 
only embers are remaining from the initial wood added 
to the
fire, new wood can now be added as required (hard-
wood is ideal).
12. Depending on the weather conditions, adjust the 
control lever towards the middle setting or a little over.
The correct setting is always based on experience and 
the current local conditions.
13. Always open the firebox door slowly. This will 
ensure that you avoid sudden low pressure in the fire-
box and prevent exhaust gases leaking into the living 
room.
14. This will prevent any possible smoke leakage 
through the opened door when adding new wood 
during the ember phase.
15. Never consistently add more wood than the recom-
mended amount . 

Caution: The height of the wood pile must not exceed 
the lower marking on the deflector plate!

6.3.1 FLASH FIRE

A flash fire is a small fire burned quickly when you 
don’t need much heat. After your kindling has “caught”, 
load at least 3 pieces of wood, stacked loosely. Burn 
with the draft control fully open if adjustable or open 
the door upward with 1 1/2 inches for 3 minutes if 
required.

6.3.2 EXTENDED FIRE

Load your larger pieces of wood compactly, packed 
close enough to prevent the flames from penetrating 
it completely. 

DO NOT OVERFIRE THE APPLIANCE!
OVERFIRING CAN OCCUR BY:

A. Burning large amounts of smaller wood pieces such 
as furniture scraps, skids or treated wood.
B. Operating the appliance with a poor gasket seal on 
the main door.
C. Overfilling your appliance. Go by the following 
specifications:

Appliance

Wood consumed per hour 

Insert-600

1,8 kg/hr

Insert-700

2,1 kg/hr

6.3.3 SMOKING

A properly installed appliance should not smoke. If 
yours does, check the following:

Has the chimney had time to get hot?
Is the smoke passage blocked anywhere in the appli-
ance, chimney connector or chimney?
Is the room too airtight and the air intake not con-
nected to the outside? Try with a window partly open.
Is the smoke flow impeded by a too long horizontal 
pipe or too many bends?
Is it a weak draft perhaps caused by a leaky chim-
ney, a cold outside chimney, a too large diameter of a 
chimney, a too short chimney, or a chimney too close 
to trees or a higher roof?
Has a direct flue connection been used rather than a 
chimney liner continuous from cap to appliance flue 
collar.

7. MAINTENANCE

WARNING

APPLIANCE MAY BE HOT, DO NOT SERVICE UNTIL 
APPLIANCE HAS COOLED. DO NOT USE ABRASIVE 
CLEANERS.

Check your chimney and chimney connector for creo-
sote and soot buildup weekly until a safe frequency for 
cleaning is established.

If accumulation is excessive, disconnect the appliance 
and clean both the chimney and the appliance. You 
may want to call a professional chimney sweep to 
clean them. Both have to be cleaned at least once a 
year or as often as necessary.

Remove baffle plates and clean above them once a 
year. Replace any broken bricks.
