INSTALLING THE APPLIANCE
Pre-installation notes
1. Check the stove data plate to establish the gas type required. The data plate can
be found on a chain at the top left rear corner of the stove.
Before installation check that the local distribution conditions, nature of the gas
and pressure, and adjustment of the application are compatible.
2. A CORGI 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.
3. All outer surfaces of the stove excepting the gas control knobs are defined as
working surfaces.
4. Installation site
Any installation area previously used for a solid fuel fire or stove would probably
be deemed suitable for the appliance.
5. The stove must not be installed onto a combustible wall. Any combustible
materials must be removed from behind the appliance.
1. The appliance must be sited on a non-combustible hearth of minimum 12mm
thickness.
7. The hearth should be edged or raised to prevent combustible floor finishes
(e.g. Carpet) from being laid too close to the appliance.
8. Opening Clearances
For the relevant clearance distances for installing the appliance in an opening see
diagram 2 below:
4
Diagram 2

IMPORTANT NOTE! Adequate clearance must be given between the appliance and
the walls so that a satisfactory spillage test can be performed as detailed on page 15.
Flue Arrangement
The CORGI 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 Herald 6 gas stove must comply
with the current rules in force.
(The Herald 6 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.
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.

Removing the Stove Body
THE BODY OF THE STOVE IS HEAVY! To reduce weight it is recommended that the
cast iron doors be removed before attempting to remove the stove body.
Removing the Cast Iron Doors
Open the right-hand door. While holding the door
with one hand, gently push up the two hinge pins
(Top and bottom) with the other hand. Remove the
hinge pins and the door can then be removed.
Carry out the same process for the left-hand door.
Removing the Stove Body
The stove body is secured in place by four 13mm
bolts. Two of the bolts are located just inside the
door opening (Diagram 4) and two at the back of
the stove (Diagram 14 – Page 14). Slacken the rear
bolts using a 13mm socket/spanner and remove the
front bolts (Diagram 4). Gently pull the body
forward. The body can then be lifted away from
the stove.
Removing the Glass
The glass is held in place by 4 fixing clips, 2 at the
top and 2 at the bottom. Slightly slacken the lower
two fixing screws with a flat blade screwdriver.
There is no need to fully remove the screws.
Holding the glass with one hand, as shown in
diagram 5, slacken the top 2 fixing screws until the
clips have moved away from the glass panel. The
glass panel can then be lifted out.

Gas Supply Connections
The appliance is supplied with a 8mm Bundy pipe and a 8mm compression elbow to
allow easy connection to the mains gas supply. This supply gas pipe should incorporate a
gas service isolation tap that is situated within 1 metre of the application.
Diagram 6 shows the 8mm Bundy pipe being
fitted to the gas inlet on the valve. The
compression joint is tightened with a 12mm
open-ended spanner.
Testing Supply Pressure
1. Gas pressure at the appliance is measured via the rearward test nipple (Test nipple
‘A’ in diagram 7) on the left-hand side of the control valve. (Turning the screw
approximately half a turn anti-clockwise with a small flat-bladed screwdriver opens
the test point.)
ALWAYS CLOSE TEST POINTS AFTER USE!
2. The gas pressure at the appliance is measured with the appliance running at full
rate. (For information on how to achieve ‘full rate’ read ‘Adjusting Between High
and Low Output Settings’ in the ‘Lighting the Appliance’ section of the User
Instructions.
Burner Gas Pressure should be:
Natural Gas@ 19mBars
LPG @ 36mBars
3. The supply pressure coming into the appliance can also be checked by using test
point ‘B’, shown in diagram 7.

Fitting the Loose Ceramic Coals
4. The first row of coals consists of 4
small coals and 4 large coals. The first
row of coals are placed so that they sit
on top of the front and middle ceramic
matrices.
Starting with a large ‘diamond shaped’
coal, place the front of the coal on top
of the left hand support leg of the front
ceramic. The back of the coal should
rest on the middle ceramic. Then take a
small coal and place the front of it in
the first left notch in the front ceramic,
the back of the coal resting on the
centre ceramic.
Continue this process, alternating the
coal size until all the 8 coals are placed
as shown in Diagram A11.
Note!
Make sure that the coals do not fall down between the front and middle matrices.
A gap must be left between the coals to allow the flames to pass through.
5. The second row of coals consists
of 4 medium sized coals. They are
placed between the large coals so
that they sit on the middle ceramic,
shown in Diagram A12.
Note!
The coals must not block the gap
between the middle and rear ceramic
matrices.
6. The third row of coals consists
of 6 medium sized coals (6 small
coals for LPG stoves). The coals
are placed so that they sit on top
of the last row of coals and into
the notches on the rear ceramic
matrix, shown in Diagram A13.
Note!
Gaps must be left between the
coals for the flames to pass
through.

7. The fire-bed should now be completed. The stove should be lit and the flame picture
checked with the glass panel fixed securely in place. Any adjustments to the flame picture
can then be made as required.
The stove can now be re-assembled as shown in ‘Re-assembling the Stove’ – Page 14
Section B - Fitting the Log Effect Ceramic Matrices
The fire-bed is constructed of 3 ceramic matrices and 6 loose logs.
A. Place the rear ceramic matrix into the
fire as shown in diagram B8.
The ceramic should sit on the burner
tray top and be placed so that it touches
the back of the firebox. As shown in
Diagram B8.
B. Place the middle ceramic matrix into
the fire so that the flat surface sits on the
burner tray. Push the middle ceramic
back until it rests against the rear ceramic
shown in diagram B9.
Note!
Make sure that the middle ceramic does
not block any of the burner tray slots.

log, place at the angle shown in
diagram B11. The bottom of the
log should sit in the cut-out on
the front ceramic matrix, with
the flat underside of it resting on
the flat area on the middle
matrix. Of the longer 2
branches, the tip of the right
hand branch should rest in the
left hand cut-out on the rear
ceramic.
E. The second log has two short
branches coming from it. It sits in the
furthest left cut-out on the front ceramic
and rests in the groove on the centre
ceramic, shown in diagram B12.
F. The third log to be placed is the thin
‘twig’. The ‘Twig’ is placed in the cut-
out between the first two logs. The
small branch on the twig should sit at an
angle into the cut-out on the front
ceramic and so stopping the twig from
falling between the front and centre
ceramic. The top of the twig should rest
on the large log as shown in diagram
B13. (Make sure that the position of the
‘Twig’ does not block any of the burner
ports)

G. The fourth log is the shorter of
the two straight logs. The log should
rest on the middle ceramic on the
flat section to the right of the large
log. The top of the log should rest in
the groove on the rear ceramic, as
shown in diagram B14.
H. The fifth log is the longer of
the two straight logs, the top of
this should sit in the final
groove on the rear ceramic in
between the large log and the
shorter straight log. The log
should also rest on the join
between the other 2 placed logs
as shown in diagram B15.
I. The sixth and final log has
a single branch coming from
it and one end is shaped to
be parallel with the mirrored
side. It should sit on the flat
surface on the centre
ceramic as shown in diagram
B16.
J. The fire-bed should now be completed. The stove should be lit and the flame picture
checked with the glass panel fixed securely in place. Any adjustments to the flame
picture can then be made as required.

RE-ASSEMBLING THE STOVE
8. When the desired flame picture has been achieved, the stove body can be
reassembled.
The stove body can be slid back into place, making sure
that the body locates onto the 2 securing bolts at the back
of the base, shown in diagram 14 (There is no need to
tighten these down).
The two front fixing bolts can then be replaced and
tightened to fix the body in place (Shown in Diagram 4 –
Page 6).
9. The cast iron doors can then be refitted which is the
reverse process of that shown in Diagram 3 – Page 6.
FITTING THE CANOPY – (OPTIONAL)
There are two types of canopy available for your
Hunter Herald 6 gas stove.
The options available are:
• Low Canopy
• High Canopy
Both canopies fit in exactly the same way.
Once the stove body has been secured, the canopy
can be simply slid into place on the top plate of the
stove body (Shown in diagram 15), making sure that
the two welded tabs (located either side of the
canopy) fit under the top plate.
The canopy is then secured in place by
tightening the fixing screws (one located either
side of the canopy) with a flat-bladed
screwdriver, shown in Diagram 16.

TEST FOR SPILLAGE
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.
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, as shown in diagram 17.
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.
SPILLAGE MONITORING SYSTEM
This appliance is fitted with an ‘oxygen depletion system’ (ODS) pilot assembly
which will monitor any spillage from the appliance.
The system MUST NOT be adjusted or changed by the installer.
Replacement systems must be obtained from Hunter Stoves; no other pilot assembly
must be substituted in its place.
OPERATING THE APPLIANCE
FULL OPERATING INSTRUCTIONS ARE GIVEN IN THE USER INSTRUCTIONS.
Fitting the Remote Control (Optional)
Fitting the Motor to the Valve
Un-screw the cover retaining
screw with a small Philips
screwdriver, shown in Diagram
18. Prise off the cover at the snap
connection that is located on the
right-hand side of the valve with a
small flat-bladed screwdriver.
15
Diagram 17
Diagram 18

Turn the main burner control
knob (Knob ‘B’ – diagram 19)
fully anti-clockwise until the end
stop is reached.
Fit the motor as shown in diagram
20, making sure that the motor sits
on the locating pin.
Replace the valve cover and
tighten the Philips headed screw.
(Do not over-tighten the screw as
this may effect the operation of
the control). Make sure that the
snap connector has located
properly. When fitted correctly,
the valve cover holds the motor in
the correct position.
Attaching the Remote Control Receiver Box
The control lead is then attached to the receiver box using the plastic connector and to
the valve motor by the two spade terminals.
The Remote Control Receiver Box is powered by 4 x AA batteries (supplied). The
batteries are fitted by sliding the cover off the receiver box the orientation of the
batteries shown on the diagram in the box.
Fit the 9-volt battery to the remote control handset.
Test that the remote control system is working by pressing the increase and decrease
buttons on the handset.
If the system is working correctly, the receiver box can be sited. The ideal position for
the receiver box being on the hearth, at the back of the stove. The remote control
system is ultra-sonic and hence the receiver box does not have to be in line of sight of
the remote handset.
WARNING!
The receiver box should not be sited anywhere that the temperature will be greater than
50°Celsius. High temperatures will shorten the battery life and may cause the remote
control receiver to stop operating.
