NSTALLING 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 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.
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.
6. 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 when installing the appliance in
an opening see diagram 2 below:

Issue F: 18/02/14

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 Verona gas stove must
comply with the current rules in force.
(The Verona range of stoves 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.
The flue must have a minimum of 2.6 meters of vertical height measured
from the top of the stove to the bottom of the terminal outlet. 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
First completely remove the 2 securing
bolts that are located behind the valve
cover plate by using a 10mm spanner,
as shown in Diagram 3. Make sure
that the 2 rear fixings (Diagram 18 –
Page 16) are loose.

Issue F: 18/02/14

Gently slide the stove forward and lift
clear of the stove cartridge (Diagram 4).
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, slacken off the top 2
fixing screws (Diagram 5) until the clips
have moved away from the glass panel.
The glass panel can then be lifted out.
Levelling the Stove
To achieve the optimum operating results the
stove should now be levelled with its
surroundings. This is carried out by
increasing or decreasing the length of the
levelling bolts located at the foot of each of
the stove legs, shown in diagram 6.

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 7 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 8) 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

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 A12.
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 A13.

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 B15.
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

TEST FOR SPILLAGE
A Spillage test MUST be carried out 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, both sides of
the TTB Bracket as shown in diagram 17.
Most of the smoke should be drawn into the
draught diverter. If not, leave the stove running
at full rate for a further 10 minutes and repeat
the test. I
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 or
ventilation may require attention. The stove
should not be used until the fault is rectified.
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 HS Gas; no other pilot
assembly must be substituted in its place.
The appliance is also 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 TTB MUST NOT be
removed or ‘bridged out’ for any reason and only genuine HS Gas
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.

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.
