Chimney Fires - Heta Scan-line 7 Series Operating And Installation Instructions

It is advised not to use very oil-containing
woods like teak tree and mahogany, as this
can cause damage to the glass.
heating value in wood
You have to use about 2.4 kg normal wood to
replace one litre of heating oil. All woods have
almost the same heating value per kg, which
is about 5.27 kW/hour for absolute dry wood.
Wood with a moistness of 18% has a efficiency
of about 4.18 kW/hour per kg, and one litre hea-
ting oil contains about 10 kW/hour.
Co release

At combustion 1000 litres of heating oil forms
3.171 tons CO . As wood is a CO

energy source, you save the environment about
1.3 kg CO every time you have used 1 kg nor-

mal wood.

Chimney fires

In the event of a chimney fire – which often re-
sults from incorrect operation or protracted fi-
ring with moist wood – close the door and shut
off the secondary/start-up air supply to smother
the fire. Call the fire department.
airflow regulation
The stove is supplied air by means of the control
handles placed at the back of the side panel of
Scan-Line 7 B C D. See figure 1.
The secondary airflow handle is the upper hand-
le and the one for the the start-up airflow is the
one below. The secondary airflow is completely
open in top position.
The secondary air is gradually closed during
firing. The damper closes after start-up.

On the Scan-Line 7 L, the controls are located at
the bottom of the front, secondary air to the left
and start-up air to the right. See figure 2.

The Scan-Line 7 stoves are designed and tested
to burn extremely cleanly with very little smo-
ke discharge and are exempt for use in smoke
control areas throughout the UK when burning
dry wood logs. To comply, a permanent stop is
fitted to ensure that the air control slider cannot
be closed beyond 50% of its fully open position.
A permanent amount of air will therefore enter
the firebox to feed the fire producing negligible
amounts of smoke and unburnt hydrocarbons.
The appliances will only be considered as an
exempt appliance if this stop is in place.
lighting
To ignite the fuel, use fire lighters, small paraffin
ignition bags or small pieces of wood placed on
the bottom grate. Place larger pieces of wood
on top of this kindling material, at right angles
to the firing, doors. Completely open the start-
up and secondary air supply and leave the firing
door ajar – i.e. approx. 1 cm open. Once the fire
has taken a good hold of the fuel and the chim-
ney has heated up (after about 10 min) close
the firing door. We recommend that you burn
the entire first firing with the secondary air sup-
ply fully open to make sure that the chimney is
thoroughly heated.
Note:
If the fire dies down completely or embers are
smoldering, then it will be necessary to place
some firelighters onto the grate with some kind-
ling or small pieces of wood to reestablish the
fire once again. Leave the air control fully open
and allow the fire to build before refueling with
larger pieces of wood. Then adjust the air con-
trol for optimum combustion. Do not overload
the firebox by loading above the tertiary air dif-
