heat-resistant glass as this is made to withstand
temperatures of up to 800ºC.
Remove the screws and glass clamp washers from
each corner and place them in a safe place. Note the
gasket spacers on the top corners. Do not attempt to
re-tighten the clamps without these spacers. Always
use the correct sized Phillips crosshead screwdriver
and use releasing oil if the screws prove difficult to
remove. Be careful not to dislodge the ribbon seal. If
this is damaged or worn replace it completely. Loose
ribbon can be held in place with rope seal glue
available from your dealer. Lubricate the screws and
holes and reverse the process, being careful not to
over-tighten the screws and clamps in case you break
the glass.
• Paint Finish
Your stove has been finished with
heat-resistant paint and is very easy to maintain.
Regularly remove ash and dust from surfaces with a
soft cloth or brush. To maintain the original paint
finish you can use traditional ‘stove black’ polish
which your Precision dealer can supply. Make sure the
stove is cold and use protective gloves as this type of
polish can cause deep staining to the skin and
fingernails.
Repair worn or scratched surfaces with a proprietary
heat-resistant spray paint made specially for stoves,
also available from your stove dealer. Never use an
aerosol spray on, or near, the stove when it is burning
or it is hot.
• Door Rope Seals
It is important that you maintain
a tight door seal as this prevents unwanted air leaking
into the fire chamber and helps make the Primary and
Secondary Air more effective in controlling the fire.
When the stove is cold, to check the door stove seal,
place strips of paper between the door and ‘door
frame’ and shut the door. If you have to pull hard to
remove these or they tear, then you have an effective
door seal. If these can be easily removed or if they
slide around you will need to replace the door seal.
Your new Precision stove is supplied with a spare rope
seal for the door. To replace, carefully remove the old
seal and completely clean the seal channel of debris
and old glue. Use liberal amounts of proprietary heat-
resistant fire rope glue and glue both ends to ensure
a well-sealed joint. Also replace the middle horizontal
rope that seals the ash pan chamber from the fire
chamber to maintain a good Primary Air flow.
The recommended rope seal diameter is 12mm.
• Air Supply Controls
There are three air supply
controls on the Precision Boiler stove (see page 4) and
you need to check that these remain fully functional
to ensure the best operation of your stove. Set the
Primary Air control to fully open and apply a few
drops of machine oil (there is no need to remove the
knob). Machine oil can also be applied with an aerosol
to the Secondary Air slider control mechanism under
the stove bodywork as well as the Thermostat flap
towards the back of the stove. Work the oil in by
opening and closing the controls a few times. Be
careful to protect the hearth and fireplace and any
other potentially porous surfaces from the oil and do
not use the aerosol when the stove is in operation.
STANDING DOWN
There will be some point in the year when you will not
need to use your stove for some time and taking care
to clean it thoroughly then will save you much time
later. This is also a good time to get your chimney
swept too as this will prevent any soot build up from
falling inside the stove or ‘caking’ and blocking the
flue way or flue system.
• Remove and clean any deposits from the top of the
baffle plate and check for wear.
• Remove any debris and deposits from the inside of
the stove particularly at the entrance to the flue way.
• Empty the ash pan and thoroughly clean out the ash
pan chamber.
• Check all rope seals and replace damaged ropes that
do not provide a good seal
.
• Check any fire cement bonds around the flue pipe
and other flue joints. Remove any loose cement and
re-seal.
• Check the grate for signs of wear. Excessive wear,
such as on the grate bars or fire fence which are bent
or warped, could be an indication of over-firing or
using inappropriate fuels such as petroleum coke.
Order genuine replacement components from your
authorised Precision dealer.
NB
If draining the system, do not leave the boiler
empty for any longer than is absolutely necessary and
when refilling always use a proprietary chemical water
treatment to protect the boiler from corrosion and the
build-up of solid deposits.
Never operate the boiler stove without water.
