Warning: Minimum Requirements
Before installing this appliance the installer must check that the
property in which the fire is to be installed complies with the
requirements of CE approval:
•The appliance must not be installed in a room smaller than that
specified.
•The room in which the appliance is to be installed must have a “free
air” wall vent of the specified size. This vent must be a minimum of 1
metre away from the appliance.
•The room in which the appliance is to be installed must have a window
which can be opened.
•The Inlet Gas pressure must be maintained at the specified level and
must be within +/- 1mbar of specification with all gas appliances in
the house switched on and also with just the Fire Line operating. If
outside of this tolerance the fault is most likely to be in the installation
pipe work or service governor at the meter. If the problem is the
meter governor, this is the property of the gas service provider (such
as Transco or Bord Gais) and they should be called to rectify this.
•For gas categories 2H, 2E and 2E+ only, the reduced heat output
version is available at high low input of 2.7/2.0kW at burner pressures
of 12.2/6.9mbar.
Noisy Pilot / Fire Shut Down
This appliance is fitted with a safety device. This will operate if the
requirements of the installation are not met. If the fire is run for a period of
time and starts to become noisy or suddenly shuts down this indicates a
possible problem. The most common fault is incorrect ventilation. The
ventilation is quoted as “free air” – it is not the size of the actual vent. Each
vent has a specified “free area”. Contact the manufacturer of the vent and
ask for this figure and check it complies with the minimum specified for the
appliance. This is a secondary heat source appliance and is supposed to be
used for short periods of time however it can also incorrect installation. If it
shuts down or is noisy - Do not use the appliance – Ask your installer to
return and confirm the following conditions are met before using the
appliance:
•Minimum Room Size
•Is the pilot shield fitted [see page 21]
•“Free Air” Wall Vent of specified size is installed in room.
•“Free Air” Wall Vent is not blocked.
•“Free Air” Wall Vent is over 1 metre away from the appliance.
•Gas pressure is within the specified limits +/- 1mBar.
•Room appliance is installed in has a window which can be opened.
Failure to comply with the minimum requirements of the specification will
render the appliance dangerous.

General Installation Requirements
The installation should only be carried out by a GAS SAFE
Registered fitter and in accordance with national and local
regulations for both gas & electricity.
The appliance is intended for decorative purposes only.
Foreign objects should not be placed on to the appliance or otherwise disturb
the fuel bed. Debris from any source, or soot formed, should be removed
from the appliance, see ‘Appliance Cleaning Instructions’.
The appliance may emit a slight smell for a period of time after
commissioning. This is quite normal and any odours will disperse within a
few hours of operation.
The pilot light and flame sensing device installed to the appliance are also
atmospheric sensing devices. The device is not adjustable and must not be
disabled. If evacuation of combustible products is interrupted the device
shuts down both the main burner and pilot light. In the event of a single
shut down, do not attempt to re-light the pilot within three minutes, once
three minutes have passed the appliance can be re-started in accordance
with ‘Appliance Start Up / Shut Down Instructions’. In the event of repeated
shut downs, do not use the appliance and have the flue and appliance
checked by a CORGI Engineer. If any part of the pilot assembly needs to be
replaced, including the pilot burner, thermocouple, electrode and injector the
complete assembly must be replaced with an original manufacturer's pilot
assembly by a CORGI Engineer.
Warning – Do not adjust the system.
Warning – Do not disable the flame sensing device.
Warning – Use only OEM parts.
The installation should only be carried out by a GAS SAFE Engineer and in
accordance with national and local regulations for gas. The installation must
also be in accordance with relevant parts of local and national building
regulations. For the Republic of Ireland, reference should be made to IS813
and ICP3 and any guidance notes from Bord Gais.
Read the instructions carefully before proceeding. Failure to do so could
result in an unsafe installation and may invalidate the warranty.
Failure to have the fire fitted by a qualified person will invalidate the
Warranty, and CVO Fire will not accept any claims for incorrect
installation.

VENTILATION REQUIREMENTS
•NOTE: The “FREE AIR” quoted above is the area of air which can pass
through the air vent. It is not the size of the grille on the wall. If in
doubt please contact the vent manufacturer and get the specification
for the vent.
•3.5Kw Version - The area the fire is to be installed in must have a wall
vent of at least 125cm² of ventilation (FREE AIR) and an open-able
window.
•2.7Kw Version - The area the fire is to be installed in must have a wall
vent of at least 100cm² of ventilation (FREE AIR) and an open-able
window.
•The wall vent must be positioned at least 1 metre away from the
appliance.
•Republic of Ireland – Two free air wall vents of not less that 60 cm²
each, one not less that 1.6m above the other, must be installed in the
room.
•When providing ventilation openings consideration must be given to
the avoidance of locations where discomfort from draughts may cause
the user to block the openings. Similarly the possibility of curtains or
furniture blocking ventilation openings must be considered.
•Floor vents, window vents or chimneys are not suitable means
of ventilation. On no account must inlet or outlet grilles be
obstructed. Working services include the air outlet grille.
•NOTE: In some installations, if the fire shuts down, additional
ventilation may be required. This can be due to how air circulates
within the room. If this is the case it is advised to add a second vent
positioned away from the first vent at a higher level.

Page 11 of 34
SECONDARY HEATING: The fire is intended as a secondary heat source and should
not be used as a primary heat source.Check that a primary heat source (such as
radiators) is present in the room before installing the appliance. The fire should not be
operated if the room temperature is below 15 deg C. If the fire is used in a room without
the primary heat source operating to raise the initial room temperature above 15 deg C
there may be a build up of condensation and it is likely the stone fascia will crack due to
heat shock. When the appliance is used properly there is no risk of the fascia stone cracking
and this damage is not covered by the warranty. Houses with warm air heating systems,
solid walls, or no damp proof course may be unsuitable for flueless appliances. This
appliance does not contain Asbestos.
ROOM AIR QUALITY: The fire must not be used in rooms where the atmosphere is likely
to contain water or chemical vapours that may adversely affect the appliance or its finish
e.g. a kitchen
DECORATING: Do not use the fire while painting or decorating even if it is in an adjoining
room. When decorating the residue can linger for some time and this will lead to unpleasant
smells from the appliance. It may be some weeks before this odour clears and it is advised
not to use the appliance during this period. Always completely cover the appliance while
decorating.
WALL MOUNTED: The appliance has been designed to be installed onto a wall. It must be
placed on a non-combustible surface of minimum of 12mm thickness. The surface on which
the appliance is to be mounted must be flat, level and square to the back panel. Care should
be taken with all wall coverings as it may discolour them in time.
GAS SUPPLY
Before working on any pipe work, plug the ends to prevent the entry of
debris. Decide upon the route for the gas and lay pipe work as required.
Where pipes pass through the walls they must be sleeved. Before
connecting any pipes to the appliance, fully purge pipes of debris or grease
etc. Inlet is via an 8mm gas tap (isolation valve) which is supplied fitted to
the appliance. Connect gas supply to the supplied pressure test point and
then to the 8mm isolation valve as shown below. The pressure test point
MUST BE as close to the isolation valve as possible to ensure
accurate inlet pressure testing when the fire is commissioned.

Page 12 of 34
SIDE VIEW of the Flueless Fire Line (below)
On no account must inlet or outlet grilles be obstructed.
Only the fascia supplied with the appliance must be used. Any other type
could affect combustion or overheat the gas controls. Any other types of
Fascia must be passed by CVO.
If fitting over an existing fireplace, the flue and cavity must be blocked off
completely to prevent suction on the back of the appliance. The top of the
flue should also be capped off to prevent the entry of moisture etc. Consult
building control if in any doubt.
Any under grate draught devices must be sealed off. A hearth will be
required in accordance with both CORGI and local regulations on a non-
combustible surface if the fire is to be mounted on the wall less than 300mm
from the base of the burner to the floor.
The client/installer can construct/supply their own hearth or CVO can supply
it as an extra item.
Unless a dress guard is fitted, this appliance shall be installed with a hearth
that projects at least 300mm in front of the naked flame/incandescent fuel
bed, and extends at least 150mm at either side, and around its periphery is
a height of at least 50mm above finished floor level.

Page 13 of 34
Warning for Fire Guards and Hearths
The appliance is not installed with an integral guard. In normal use
consideration may be given to the use of a fireguard conforming to BS6539
or BS6778, so that the approach to the appliance is limited such that access
to the flame is minimised. It is recommended that a fireguard conforming to
the requirements of BS6539 or BS6778 be installed if the appliance is used
in the presence of young children, the elderly or the infirm. For some
countries a non-combustible hearth must be installed in front of the
appliance in accordance with national regulations (e.g. United Kingdom). In
addition, the installer is to advise the user against placing combustible
material directly in front of the appliance.
Clearance to Combustible Materials and Shelves
A non-combustible shelf may be fitted to within 1500mm of the top edge of
the outlet of the fire. Note that shelves will get hot and delicate ornaments;
e.g. wax candles etc. should be kept away from hot surfaces.
As with all flueless fires the possibility of convection staining on surfaces in
the vicinity above the fire outlet shall be considered and the user advised.
Particular attention should be taken to ensure soft furnishings such as
scatter cushions, rugs and curtains are kept at least 1.5 metres from the
appliance. Material of any description should not be thrown on to the fuel
bed.
Preparing the Appliance for Installation
Unpack the unit. Ensure the appliance is correctly marked for the gas it is to
be used with. Take the fascia panel and stand this against a flat surface – Do
not lay the fascia flat.
DO NOT ATTEMPT TO USE THE APPLIANCE IF ANY PART OF THE
APPLIANCE IS FOUND TO BE DAMAGED.
Decide upon a route for the gas supply and if this is to be a concealed supply
it needs to be located to the bottom right of the fire. Lay in the supply as
required. Where pipes pass through a wall, cavity or un-vented void there
should be no joins in this area and the pipes should be fully sleeved. Before
pushing gas pipes through walls seal the pipe ends to prevent debris
entering the pipes.
The instructions for installation and maintenance and the user instructions
shall be handed to the user. The installer shall instruct the user in the safe
use and regular maintenance of the appliance and advise that the ventilation
opening shall not be blocked or restricted in any way.

Before Connecting the Fire
Check ROOM SIZE REQUIREMENTS.
Check VENTILATION REQUIREMENTS.
Check GAS PRESSURE REQUIREMENTS.
Fully purge pipes of air and any debris and connect the gas supply to the
8mm supply on the fire. Leak test the supply using an approved method.
Note: An isolating valve must be situated near the appliance for servicing.
In the even of gas leakage from the appliance the gas supply must be
turned off at the nearest isolating valve.
Before lighting, if the pipes have not been purged of debris do so
now before lighting the fire. Failure to do so will result in blockages
within the pilot.
All CVO gas fires are bench run and thoroughly tested. CVO is in the unique
position of knowing that every fire that leaves the factory in perfect working
order with accurate test records kept for every fire. This ensures every fire
complies with the CE approval.
Connect the 8mm gas inlet to a gas inlet test elbow. This should be
positioned as shown in the images. The elbow should be connected to the
isolation valve as shown in the images.
Gas Inlet Supply – This is via an 8mm gas tap (isolation valve) which is
supplied fitted to the appliance. A Gas Inlet Elbow is required to check inlet
pressure. This is supplied with the fire and must be position as close to the
isolation valve as possible.
It is recommended that if the gas pipe work is in excess of 1.5m the size of
the pipe work should be increased in diameter after this point to ensure a
stable gas supply.
IMPORTANT NOTE: LPG/Propane:
With Outside Tank: The tank must be fitted with a regulator and
suitable pipe work used to ensure the gas pressure (as stated on the data
plate) is maintained at all times. The pressure must be tested “at the
appliance” – see commissioning.
With Bottles: The minimum requirement is 2 x 47Kg bottles with a
changeover valve. Any other connections using bottles will result in
shutdown problems and damage to the fire. The bottles must be fitted with a
regulator and suitable pipe work used to ensure the gas pressure (as stated
on the data plate) is maintained at all times. The pressure must be tested
“at the appliance” – see commissioning.

Fitting Instructions
1. Refer to the section “unpacking the appliance” on page 7.
2. Positioning Wall Bracket.
a. The wall must be flat and level otherwise the burner flame will
be affected.
b. The Wall on which the fire is to be installed must be secure and
able to withstand the weight of the Fire and Fascia.
c. Decide preferred height of fire. (NOTE – There must be at least
300mm clearance between the floor to the fire opening and
1000mm from the top of the gather to the ceiling.
d. To get the desired height measure from the floor to the top of
the gather. Place the top of the wall bracket central and 40mm
lower than the gathers height, and mark out the holes.
e. Drill and plug holes and attach the fixing bracket to the wall
using 3 screws.
3. Place the gas burner unit enclosure onto the wall bracket. Mark out the
position of the lower securing points which are located within the
burner workings [see A above]. Remove the burner and drill and plug
holes then refit the burner onto the wall bracket and secure using the
two screws provided. WARNING: This must be done as it ensures the
fire cannot be lifted from the wall and the burner cannot warp while
operating.
4. A qualified GAS SAFE registered gas fitter must connect the gas to the
fire using the pressure test point provided. [See “Before Connecting
the Fire” Section – Page 14]
5. Once the fire is connected to the gas, fit the fascia in place by locating
the lugs on the back of the fascia into the slots on the burner housing.
As the fascia is heavy, it is advisable that another person helps.
6. Once fitted the fascia must be locked in place, this is done by locating
two cross-headed screws through both the fascias hanging bracket and
the enclosure situated on each side of the unit. [See Page 28]
7. A qualified GAS SAFE registered gas fitter must commission the fire.
[See “Commissioning the Fire” Section – Page 16]

Page 16 of 34
Commissioning the Fire
Refer to ‘Lighting the Fire’ Section for information on the start and shutdown
procedure. WARNING: UNDER NO CIRCUMSTANCES ADJUST THE
FLOW RATES FOR THIS APPLIANCE. The inlet flow rates for the fire are
factory set and are sealed and do not need further adjustment. This ensures
that the appliance complies fully with CE approval.
Test the Gas Pressure.
Ensure the fire has been installed using the test point provided and
in line with the image on PAGE 11.
1. Attach a manometer to an inlet test point next to the isolation valve.
2. Light the Fire and set on the “maximum” heat setting.
3. Check that the inlet pressure is within the allowed tolerance of (+ or -
1mb). For example in the UK – Natural Gas (20mBar) should be within
the range of 19 to 21. Propane (37mBar) will be 36 to 38.
4. Now turn on all the other gas appliances in the house and check that
the pressure still remains within the tolerance of +/- 1mb.
5. Now turn off all the other gas appliances and turn the fire down to pilot
only and check that the still remains in the tolerance of +/- 1mb.
IF FAILED : If the appliance fails the above test it must not be used until
either the gas pipe work to the appliance has been improved or the governor
to the house has been adjusted by TRANSCO, BORD GAIS or the propane
supplier. Running this type of appliance with incorrect gas pressure can
result in harmful emissions being released into the room and will render the
appliance dangerous.
IF PASSED : Disconnect the pressure gauge then replace the pressure test
point sealing screw and test for gas soundness. Replace the cover and the
control knob [if removed].

Installation Completion & Final Check List
Brief the customer on the operation of the appliance and give them the
instruction booklet. The customer must be told of the need for regular
servicing of the appliance (every 12 months), this will be at least once a
year, and they must be made aware that no rubbish is to be thrown onto the
fire bed. The customer must also be aware that purpose provided
wall vent “free air” ventilation should be checked regularly and must
“never” be intentionally blocked. The Fire is supplied with a
Warranty Card this should be completed by the installing Engineer
and handed to the customer for return to the factory.
•Is the Gas Pressure Correct? (within 1mb of rating)
•Is the Air Vent fitted and providing the specified amount of
“free air” – if in doubt contact the vent manufacturer for vent
“free area” sizing.
•Does the room comply to the minimum size or greater?
•Does the Room have a window that can be opened?
•Has the customer being shown how to operate the appliance?
•Has the customer been told of the reason for the air vent and
why it must never be blocked?
•Has the warranty card been completed and given to the
customer?
If you have any questions, or the fire is not operating correctly,
please use the fault diagnosis section or call the CVO Technical team
on 01325 327221 BEFORE you leave the installation. As part of our
Customer Service procedure you will be asked for the Fire Serial
number [on the front cover of the booklet] and Gas Safe
