be found bolted to the inside of the door
Before installation check that the local distribution conditions, nature of the gas
and pressure, and adjustment of the application are compatible
2 This appliance is intended for use on a gas installation with a governed meter
3 A GAS SAFE REGISTERED INSTALLER or equally recognised competent
person must fit the appliance That person is legally responsible for the safe
installation of the appliance with due regard to all relevant local and national
building regulations
4 All outer surfaces of the stove excepting the gas control knob and valve cover
flap are defined as working surfaces
Installation site
5 Any installation area previously used for a solid fuel fire or stove would probably
be deemed suitable for the appliance

Flue Arrangement
The GAS SAFE REGISTERED ENGINEER commissioned to install this
appliance is wholly responsible for deciding the suitability of any flue
arrangement to operate in conjunction with this gas appliance.
The chimney or flue system that is to be fitted to the Hawk gas stove must comply with
the current rules in force
(The Hawk gas stove is also suitable for other specific class 2 installation arrangements:
pre-cast flues, ridge-vent flues and pre-cast chimney block and with the relevant
adaption, the appliance will operate in a closure plate type system )
It is suggested to run flue pipe at least 615mm vertically from the unit before there are
any changes in direction of the flue system Wherever possible horizontal runs of the flue
system should be avoided
It is suggested that the flue has a minimum of 3 meters of vertical height Please note for
rear flue appliances it is recommended that the vertical flue run be established as soon as
is practical from the rear flue exit (Caution should be taken locating the exit of the flue
as explained in ‘The Building Regulations - Document J’ )
Before commencing any installation work the installing engineer must check that the flue
is free from all blockages, the chimney should be given a precautionary clean, and finally
the chimney should be smoke tested to ensure soundness Additionally any flue dampers
must be permanently fixed open or removed altogether
The flue collar and flue blanking plate should be fitted to the stove using the supplied
gaskets
Additional Air Venting (GB Only)
The supply gas heat input into the appliance is nominally less that 7kw, therefore under
the directives of the current gas safety and use regulations (1995) No additional air vents
are required in the room the appliance is situated

7
Opening the Stove Door
NOTE! This appliance must never be used with the door open or removed.
Before gaining access to the burner tray, first make sure that the stove is switched off and
is cold Now the cast iron door can be opened, this is secured in place by one fixing bolt
Firstly remove the door handle by turning anticlockwise
Keep turning until the handle is completely removed, as
shown in diagram 3
The door-fixing bolt can then be removed using a
13mm spanner as shown in diagram 4
Gas Supply Connections
The appliance is supplied with an 8mm Bundy pipe and an 8mm compression elbow to
allow easy connection to the mains gas supply This gas supply pipe should incorporate a
gas service isolation tap that is situated within 1 metre of the application
Diagram 5 shows the 8mm Bundy pipe
being fitted to the gas inlet on the valve
The compression joint is tightened with a
14mm open-ended spanner

Testing Supply Pressure
ALWAYS CLOSE TEST POINTS AFTER USE!
The gas pressure at the appliance is measured with the
appliance running at full rate (For information on
how to achieve ‘full rate’ read ‘Lighting the main
burner’ in the ‘Operating the Appliance’ section of the
User Instructions)
The test point should be opened with flat bladed screwdriver and
is shown in diagram 6
Burner Gas Pressure should be:
Natural Gas@ 19mBars +/- 0.3mBar

FIRE-BED ARRANGEMENT
F ITTING THE C ERAMIC M ATRIX
Place the ceramic matrix onto the tray
top, making sure that the cut-outs in
both of the front bottom corners of the
ceramic line up with the corresponding
matrix positioning brackets on the tray
top This is shown in diagram 7
Pull the Ceramic matrix forward so that the
bracket fits into the hole, as described by
diagram 8 Looking from above the matrix,
make sure that the ceramic matrix does not
cover the holes in the tray top
The spacing with the bracket should central,
and even either side If you lift the matrix
slightly the channels underneath should line
up above the vertical slots in the burner
tray
This appliance can be fitted with either ‘coal effect’ or ‘log effect’ ceramics
If you are fitting ‘Coal Effect’ ceramics please follow the instructions set out in ‘Section
A – Fitting the Loose Ceramic Coals’ - Page 10
If you are fitting ‘Log Effect’ ceramics please skip ‘Section A’ and follow the instructions
set out in ‘Section B – Fitting the Loose Ceramic Logs’ - Page 12

4 x Medium Ceramic Coals
2 x Large Diamond Ceramic Coals
The first coals to be placed are the two ‘Diamond’
shaped coals These should be placed in diamond
shaped cut-outs as shown in diagram 9 Make sure
that the coals do not block the flame port holes in
the matrix
The next coals to be placed are four of the
medium coals In a similar fashion to the coals
already placed, these should be positioned around
the flame port holes in the matrix as shown in
diagram 10
Finally the five small coals are
located behind the existing row
of coals, this time to each side of
the rear holes in the matrix so
that they rest on the back of the

T EST FOR S PILLAGE
A Spillage test MUST be made before the appliance is left with the customer
Carry out the test by first closing all doors and windows in the room containing the fire
The Ceramic Coal, or Log picture complete, the door sealed and handle replaced
Ensure that the fire is burning at full rate for a minimum of 5 minutes
Using a smoke match – run along the edge of the draught diverter, both sides of the TTB
bracket (located at the rear of the stove), as shown in diagram 20
If most of the smoke is not drawn
into the draught diverter leave for a
further 10 minutes and repeat test
If there is a fan in an adjoining room
the spillage test must be repeated with
the fan running and all connecting
doors between the fire and fan open
If there are still problems the
chimney/flue may require attention
S PILLAGE M ONITORING S YSTEM
The appliance is fitted with a thermostatic switch (TTB) This switch is located in the
draught diverter and shuts off the gas supply should the flue lack sufficient flow to
prevent flue gas spillage The system MUST NOT be adjusted, changed or put out of
action by the installer The TTB MUST NOT be removed or ‘bridged out’ for any
reason and only genuine Hunter Stoves replacements should be used Nuisance shut
down may occur if the stove is not installed in accordance with the clearance distances
set out in page 5

standard servicing procedures used by the servicing engineer
1 A GAS SAFE registered fitter using only original Hunter Stoves parts should
carry out servicing
1 Open the stove door as described on Page 7
2 Carefully lift-off the ‘coals/logs’ and remove the ceramic matrix
3 Using a soft brush, clean away any lint or light carbon soot deposits out of the
gas ports on the burner top plate
4 Replace the ceramic matrix and loose ‘coals/logs’ as per the arrangement
instructions (Page 9- Fire-bed Arrangement) using all re-serviceable ‘coals/logs’
and any new replacements
5 Check the gas operating pressure and pipe work for soundness, carry out a
spillage test and check the condition of the flue system
6 If for any reason the TTB switch is removed or replaced during a service, we
recommend wiping the mating surfaces clean and re-applying a thin smear of
150°C Heat Sink Compound to the face of the TTB
