Boiler room & chimney
The construction regulations of the National Housing Board include detailed norms for the design of
the boiler room, position of boilers in boiler rooms, performance of gas flue etc.
The boiler room has to
have a supply air valve with an at least 2 dm² area, this may not be closed during the time when the
boiler is operating. Exhaust fan may not be installed inside the boiler room.
The installer and chimney-sweeper could give closer information.
The boiler should be placed on a flat and stably molded concrete bed.
The chimney connection
The ULMA LAMBDA BOILER has a design of the combustion chamber and flues that give the
possibility of firing with very high efficiency. The boiler is suitably connected to chimney/gas flue with
the provided turning flue pipe horizontally. The flue pipe canal may
never go down. The chimney
should be inspected and possibly test pressed before installation if is has never been used and had
continuous maintenance by the local chimney-sweeper. At the slightest doubt, contact your certified
chimney-sweeper for inspection. Note that at too low flue gas temperature the flue gases can
condense with a risk of frost damage on the chimney as result. As a rule you should aim at least 70-
80°C flue gas temperature 1 m down in the chimney when the burner is running, this is primarily valid
for brick chimneys or similar material. The choice of flue gas temperature depends on the design and
isolation of the chimney, a steel chimney or bricked chimney with flue lining tube will not be as easily
damaged of low flue gas temperatures, provided that possibly condensate is continuously drained
from the lowest point of the chimney. This is the responsibility of the installer to control at installation.
Place the boiler at least 100 mm from the wall/bricks to facilitate service. Also leave room for possibly
existing cleanout door in the brick wall.
If the chimney is made out of bricks, you
have to take up the hole in the chimney
shaft so that there is an approx. 20 mm
blank space around the pipe. Then place
the pipe in the chimney shaft and mark out
the dept. Cut the pipe if needed. The pipe
should be placed so that it does not cover
the hole of the flue from above in any way.
Then wrap the pipe with a according to our
recommendations with 2-3 layers of heat
resistant insulating mat. Thickness of the
insulating mat is as normal standard
approx. 12 mm. Then add some extra
isolation from the outside in the opening
and then clean the wall brickworks.
Water the polish with a sprinkler a couple of
hours after to avoid cracking if the polish
burns too fast. The insulating mat makes it
closely and at the same time you escape
cracking in the chimney wall since the pipe
can move a little from thermal expansion.
The draft limiter ( Back draft door)
The draft limiter shall at installation be
adjusted by the installer of approx.
0.15 hPa under pressure. Too low under
pressure can create problems with
overheating of the burner and risk for
accumulation of flue gases in the hearth
that leads to producer gas puffs at the
ignition moment of the burner, a too high
under pressure can cause ignition problem.
