1.0 Introduction – Page 4
1.1 Description
1. The Baxi Windermere RF and TF and Grasmere RF and
TF are gas fired stove - style appliances with heat inputs of
8.17 kW (27,876 Btu/h) and 6.5 kW (22,178 Btu/h)
respectively at maximum setting. They are designed to be
used on Natural Gas only at a setting pressure of 20mbar
on an installation with a governed meter. The appliances
are intended for heating and decorative purposes.
2. For details of Propane appliances see section 13.0
Propane Models.
3. They incorporate a safety feature in the form of a spillage
monitoring system which must not be adjusted or
bypassed.
4. The stove is controlled by a knob which is positioned at the
lower right hand side of the appliance (Fig1). The knob has
four positions:
OFF IGN LOW HIGH
5. The pilot will be lit at IGN.
1.2 Installation
1. Prior to installation, ensure that the local distribution
condition (identification of the type of gas and pressure)
and the adjustment of the appliance are compatible.
2. The appliance is suitable for installation only in GB. and
I.E. and should be installed in accordance with the rules in
force. For Ireland install in accordance with l.S.813
“INSTALLATION OF GAS APPLIANCES”. The
installation must be carried out by a CORGI Registered
Installer or other competent person and be in accordance
with the relevant requirements of the current GAS
SAFETY (Installation and Use) REGULATIONS (as
amended), the BUILDING REGULATIONS issued by the
Department of the Environment, BUILDING STANDARDS
(Scotland) (Consolidation) REGULATIONS issued by the
Scottish Development Department and the LOCAL
BUILDING REGULATIONS. Where no specific
instructions are given, reference should be made to the
relevant BRITISH STANDARD CODES OF PRACTICE.
2. This appliance must be installed in accordance with
the manufacturers instructions and the rules in force
and only used in a suitably ventilated location.
3. Read the instructions before installing or using this
appliance.
Notice
Discolouration of wall surfaces
Most heating appliances generate warm air convection currents
and transfer heat to any wall surface against which they are
situated.
Some soft furnishings (such as blown vinyl wallpapers) may not
be suitable for use where they are subject to temperatures
above normal room levels and the manufacturer’s advice should
be sought before using this type of wall covering adjacent to any
heating appliance.
The likelihood of wall staining from convected air currents will be
increased in environments where high levels of tobacco smoke
or other contaminants exist.
1.3 Important Information
This product contains Refractory Ceramic Fibres (R.C.F.) which
are man-made vitreous silicate fibres. Excessive exposure to
these materials may cause temporary irritation to eyes, skin and
respiratory tract. Care must be taken when handling these
articles to ensure the release of dust or fibres is kept to a
minimum.
To ensure that the release of fibres from these articles is kept to
a minimum, during installation and servicing it is recommended
that a H.E.P.A. filtered vacuum is used to remove any dust, soot
or other debris accumulated in and around the appliance. This
should be performed before and after working on the
installation.
It is recommended that any replaced item(s) are not broken up
but sealed within heavy duty polythene bags and clearly labelled
“R.C.F. waste”. This is not classified as ‘hazardous waste” and
may be disposed of at a tipping site licensed for the disposal of
industrial waste.
Protective clothing is not required when handling these articles
but it is recommended that gloves are worn and the normal
hygiene rules of not smoking, eating or drinking in the work area
are followed and always wash hands before eating or drinking.

5.0 Arranging the Coals – Page 11
5.1 Arranging the Coals
It is important that all the coals are used and arranged
as shown in order to achieve the desired flame picture.
CAUTION: The coals are extremely fragile and must be
handled accordingly. To avoid soiling ones hands,
gloves should be worn and any inhalation of the dust
should be avoided. Keep the coals away from children at
all times. Never use coals other than those supplied or
Genuine Baxi Spare Parts. Never put additional coals on
the stove. Please read section 1.3 Important Information.

gas tap (adjacent to the control knob) and fit a pressure
gauge (Fig. 20).
2. Purge the air from the appliance by pushing in the
control knob and rotating to the ignition position (Fig.
21). Allow the air in the pipework to be purged, and
then rotate the knob further to operate the piezo igniter.
The pilot should light.
3. Once the pilot is established push the control knob in
and turn to the HIGH setting. Check the setting
pressure. (Setting pressure detail found in Section 2.0
Technical Data.)
4. Turn the control knob to the OFF position, disconnect
the pressure gauge and refit the pressure test point
sealing screw.
6.3 Spillage Monitoring Device (Fig. 22)
1The stove incorporates a spillage monitoring device.
This will cut off the gas supply in the event of spillage of
combustion products into the room.
2. In the event of this occuring there is a reset procedure.
Wait for 10 minutes before trying to reset the stove.
3. Unscrew the cap off the reset device and press in the
red button with a small screwdriver or similar
instrument.
4. Relight the stove as previously described. If this is not
possible, wait a further 5 minutes before pressing the
red button. If this fails, wait until the stove is completely
cool and reset it.
5. If the stove cannot be re-set or the spillage monitoring
device is frequently activated the flue condition must be
investigated.
WARNING: The spillage monitoring device must not be
adjusted in any way. The spillage monitoring device
must not be altered so that it will not operate or be
bypassed in any way. Only use genuine Baxi spare
parts.

7.0 Checking for Spillage – Page 14
7.1 Checking for Spillage
CAUTION - Whilst checking for spillage care must be
taken to avoid touching hot panels.
1. Before starting the test, close all doors and windows.
2. Operate the stove from cold at maximum input.
3. After approximately 5 minutes check for spillage.
4. Insert a lighted smoke match in the draught diverter at
the left hand side. The match should be positioned
35mm from the top edge of the diverter (Fig. 23). All the
smoke should be drawn into the diverter. If not, wait a
further 5 minutes and repeat the test.
5. If the test is successful repeat with any extractor fan on.
If a connected room has an extractor fan, the test
should be repeated with this fan on and any connecting
doors open.
6. If spillage occurs and the problem cannot be rectified
the stove must be isolated until the problem is resolved.
7.2 Possible causes of Spillage
1. The smoke match may have been positioned
incorrectly, resulting in the smoke being picked up by
hot convected air currents.
2. The flue installation may be unsound.
3. Down draughts may be present.
4. Flue blockages.
5. Rear flue - closure plate not sealed, stove not close
enough to closure plate.
6. Top flue – flue pipe not sealed to stove spigot.
