LIGHTING THE FIRE
Thoroughly check all pipe work for leaks, especially
the pipe connections to the boiler before lighting.
Allow the Cooker to build up heat slowly at first.
Check that all dampers and catches are operating
correctly and ensure that all flue connections are
thoroughly sealed. See that the user has a copy of
the operating instructions.
Fully open the thermostat and direct damper and
kindle with paper and sticks in the usual way and
ignite by using a taper or rolled wad of paper
inserted into the ashpit. Under no circumstances
should any inflammable liquid i.e. petrol, paraffin etc.
be used to light the fire. When the fire is well
established close the direct damper fully and keep it
closed. Add fuel to the firebox as required and adjust
the thermostat to suit the current requirements.
FUELLING
When fuelling open the direct damper as this will
help to eliminate smoking. Afterwards be sure to
close the output from the boiler. Never pack fuel
tightly or fill the firebox to capacity. A lower level fire
is more effective particularly in regard to water
heating efficiency. The maximum fuel level is up to
the bottom of the firebox door and rising upwards at
a 30
o
angle towards the back of the firebox.
CONDENSATION
If the appliance is run for extended periods on a low
fire, especially when burning wood or peat the fire
can cool down to such an extent that vapour in the
flue gases may condense. This will make the inside
of the flue damp so that the soot sticks to the flue
and the tarry mixture formed may drip down into the
appliance. It is always a good idea to run at a high
rate whenever possible, because it is so easy to
light, a lot of people, especially in the Summer, run
the appliance for just a few hours with a strong
roaring fire. The appliance is then allowed to die
until the hot water is used up and then is relit. From
the appliance and flue point of view, this is a better
technique than running a low fire continually. (Fig. 7)
EXTERNAL RIDDLING
Lift the port hole cover on the ash door and insert the
operating tool into the hole until it engages with the
spigot on the grate and move vigorously. In addition
it is also recommended that the firebed itself be
thoroughly raked at intervals thus loosening up such
debris as clinker, stones, etc. which are then easily
removed. (Fig. 8).
