General information about heat
accumulating fireplaces
Heat accumulating fireplaces differ from other fireplaces
in that they are intended to provide a moderate heat
for prolonged periods with a limited time of burning.
Conventional fireplaces give off strong heat during the
burning period but with a very limited cool-down period.
The heat accumulating fireplaces from Nordpeis have
a long duct system where the heat developed in the
combustion chamber passes through the duct system
before it exits through the chimney. The heat from the
gases is absorbed by the material surrounding the
smoke ducts, and by the time the smoke exits through
the chimney. The efficiency of a well-constructed
heat accumulating fireplace is thus far better than the
efficiency of a conventional fireplace.
A heat accumulating fireplace can keep an even
temperature throughout the day with only one heating
cycle.
Double- action damper:
The stove is fitted with a double action damper, and
controls two functions: bypass and chimney damper.
When the damper rod is pulled all the way out, the flue
gasses will bypass the canal system and exit through
the chimney. This function is used when lighting the fire.
When the stove and the chimney has reached operat-
ing temperature after 10 – 30 minutes the damper rod
should be pushed half way in until a "click" is heard. In
this position the bypass damper is closed and the flue
gasses are forced through the stove's canal system
which is absorbing the heat of the flue gasses before it
is released to the chimney.
The bypass damper should also be opened before
opening the door for re-fuelling wood, and then closed
again.
WARNING: Using the stove over prolonged periods
with open bypass damper may expose the chimney
to higher temperatures that it is design for.
By pushing the damper rod all the way in, both bypass-
and the chimney damper will be closed. This closes
off the canal system from the chimney, preventing the
heat accumulated in the stove to be lost through the
chimney. This function should never be used before the
fire is out and only a bit of embers are left in the stove.
WARNING: Closing the chimney damper too early
can result in flue gasses entering the room and
cause carbon monoxide poisoning.
Convection heat
Salzburg L Convection is equipped with a convection
heat system which provides instant heat after kindling in
addition to the heat storing.
The convection can be engaged or disengaged by
opening or closing the convection grate.
Air Vent
When burning in a heat accumulating fireplaces the
air vent is traditionally kept open to a maximum. This
ensures optimal combustion and minimises carbon
deposits in the smoke duct system. In addition it makes
it easier to keep the glass clean during intensive
burning. However, should one wish for a longer burn
period and slower flames, the air vent is adjusted and
reduced. Salzburg is equipped with secondary
combustion technology, which can normally only
be found on modern fireplaces. This ensures clean
combustion and high efficiency, even at lower loads.

Cleaning the Smoke Duct System

When the fireplace is used every day throughout the
heating season, we recommend that the smoke duct
system is swept once a year. This is to maintain the
draught and efficiency. Soot isolate the ducts and
thus lower the efficiency. One can also notice that the
draught is reduced and that the flames are difficult to
control with the air vent function. Remember that the
fireplace must always be cold before it is swept /
inspected.
Sweeping of the vertical channels can be executed by
removing the inner and outer ash pan. Use a flexible
spring (steel Ø4-5mm, about 200cm long) with
accompanying brush (Ø50-80mm). Feed the spring
through the opening where the ash pan was and up the
duct system on both sides.
The entire depth of the duct system should be swept.
Soot that falls down into the bottom space under the
ash pan during sweeping should be removed using a
ash vacuum cleaner.

Ash and Ash-pan

The ash-pan consists of an inner part which is used for
the regular emptying of ashes.
The ashes must be emptied periodically. Please note
that the ash may contain hot embers even several days
after the fire has ceased. Use a container of
non-combustible material to remove the ashes.

Weight

The home owner must ensure that the floor can
withstand the load of the total weight of the product.

Firewall

Freestanding fireplaces can be installed without a
firewall. Observe all safety distances to combustible
materials.

Connection to Chimney

Follow specifications from the chimney manufacturer
for connection to the chimney. Dry stack the fireplace
for accurate height and positioning of the flue/chimney
connection.
