Ortal have now obtained certification for all the CE marked fires to use flexible flue liners - with certain conditions.

The conditions are;

1. For use only with renovation or adaptation of an existing chimney

2. The Metaloterm Renovation Kit for joining

the liner to their approved flue terminal must be used.

3. The flexible liner itself can be locally

sourced but must be approved to EN 1856-2. (This European Standard supersedes the withdrawn BS715 )

4. During installation the flue restrictor plate

size is selected using the same tables as used with rigid flues. (Restrictors are supplied with the fires)

Ortal Technical Guide December 2015

This appliance has a ceramic Fire-bed arrangement; this contains Refractory

Ceramic Fibres, which are man-made vitreous silicate fibres.

Excessive

exposure

to

these materials can cause irritation to eyes, skin and

respiratory organs.

Hence

we recommend that when handling these

materials the release of dust should

be

kept to a minimum. During installation and servicing we recommend that a HEPA filtered vacuum be used to remove any dust and soot in and around the fire. If

any

of the

ceramic fire-bed components need to be replaced we recommend that

the removed parts be sealed in a heavy-duty polythene bag, and be labelled as RCF

waste. RCF is not "Hazardous waste" and can be disposed of at a

licensed

tipping

site for the disposal of industrial

waste.

The appliance incorporates a permanent pilot. This is located on the front of

the

burner, and must not be adjusted by the installer. This system must not

be put

out

of operation, and if any parts require changing, only original

manufacturer

parts

shall be

used.

This appliance is designed to be used either Natural or LPG gas however, each

individual appliance is only capable of running off the type of gas

specified at

the

time of purchase. It is important to note that once a type of

gas has been

specified

the stove cannot run off any other type. The type of

gas that your stove is

capable

of burning is stated on the data information

panel.

This appliance has been designed, tested and approved to meet standards in place

for product use, performance and safety. Installation of your appliance

must

comply

with current building regulations. It is therefore recommend

that a registered

gas

installer be employed for this task. The engineer will

provide you with

information

about the safety limits of the installation and

should fix a notice plate in a

place

where it can be readily

seen.

This appliance is designed as an efficient heating device and consequently all body

parts become very hot in use. Except for the control knob and control access door, which are designed to stay cool, all other parts are working surfaces and

should

not be

touched.

The glass and frame on this appliance acts as a fireguard conforming to BS: 1945

—1971 and satisfies the Heating Appliance (Fireguards) regulations

1991.

No

part of the window or frame should be permanently removed. It

does not give

full

protection for young children or the infirm, extra protection

should be considered

for

these conditions conforming to BS 6539 or BS

6778.

Bearing in mind that the heat given off by this appliance may affect articles

placed

close to it, curtains should not be placed within

30cm.

The appliance is not designed as a

dryer. It is not therefore recommended

that

the

appliance be used in such a manner. Do not place any articles within

30cm of

this

appliance as this may result in damage to the

articles.

The installation must be carried out in accordance with the following regulations:

Ortal Technical Guide December 2015

Ventilation

This appliance can be installed in a completely sealed or mechanically

ventilated

house without extra ventilation and/or fume

extraction.

General Balanced Flue

Notes

There are many possibilities for installing this Concentric Balanced Flue

system

into a building, both Roof and Wall terminations are possible, and the flue

can

either be built into an existing chimney or a completely new flue system may

be

constructed.

The system is based upon a Concentric Flue system which utilises an inner flue which passes through an outer flue, for flue size see ‘Flue Design Options’ . The

flue gasses that are the products of combustion of the fire, pass through the inner flue and are safely vented to the outside environment. The gap between the inner

and

outer flues is the channel by which the stove is supplied with air for

combustion.

These concentric flues terminate outside of the property in a terminal, this

terminal

will keep the expelled gasses and the fresh air for combustion separate. It

is

important that the terminal is not blocked, a suitable guard maybe required if

the

terminal is located at a "Low" level (usually when the terminal is within 2m of

floor

level).

The Balanced Flue gas appliance can be installed as an insertion into an

existing

or new fireplace. If an existing Flue or Chimney is to be utilised, then the

installation

engineer must be consulted. If the chimney has been previously used it must

be

professionally cleaned and certified as being sound and fit for

use.

The European CE approval on this appliance is restricted to the Flue systems as specified by the supplier, thus the appliance must only be installed with the

original

flue system, no others may be

used

The gas fire, in combination with the concentric flue system, has been approved in

accordance with the European CE-norm for gas appliances and may

therefore

be used only with this system. The guarantee is invalidated if the appliance

is

(completely or partially) installed using a different

system.

The concentric flue systems can be used with either a newly-built or

existing

chimney.

These appliances are designed with the "Firebox" raised up off the ground level

by

the built in "Base unit".

Thus these appliances require no special Hearth arrangements, as the floor will not get hot and is protected by the steel construction of the "Base unit".

The appliance must not be fitted against a rear wall constructed from a

combustible

material; a gap of 300mm should be given all round the stove before

combustible

materials may be used in the wall construction.

If the appliance has to be located in an opening, a minimum clearance of

50mm

should be allowed to non-combustible

materials.

8

Ortal Technical Guide December 2015

If the appliance is located in a recess, then the recess must have adequate

ventilation, we recommend a minimum total vent area of 200 cm 2.

The stove must be located at least 280mm from any combustible materials.

Timber Frame

Construction

Whilst it is possible to install room-sealed appliances in timber frame

properties

,

great care needs to be taken to ensure that the flue assembly does not interfere with the weather proofing qualities of any outer wall which it may penetrate.

Before attempting this work, further details need to be referenced, (e.g. "Gas Installations in

Timber Frame Buildings" from the CORGI installer series in the UK).

Carport or Building

Extension

Where a flue terminal is sited within a carport or building extension,

it should

have

at least two completely open and unobstructed sides. The distance between

the

lowest part of the roof and the top of the terminal should be at least 600mm.

Note: A covered passageway should not be treated as a carport. Flues should not be sited in a covered passageway between

properties.

Basements, Lightwells and Retaining

walls

Flue terminals should not be sited within the confines of a basement area, light well

or external space formed by a retaining wall, unless steps are taken to ensure

the

products of combustion can disperse safely at all times. It may be possible to

install

this Balanced Flue system in such a location provided that it is not sited lower

than

1m from the top level of that area to allow combustion products to disperse safely.

Flue terminals should be sited to ensure total clearance of the combustion

products

in accordance with the enclosed information.

When the products of combustion are discharged, they should not cause a

nuisance

to adjoining or adjacent properties and they should be positioned so that

damage cannot occur to other parts of the building. If the outer wall surface is constructed of combustible material, a non-combustible plate should be fitted behind the

terminal

projecting 25mm beyond the external edges of the

terminal.

A. A ventilation opening serving an occupied room, a toilet or a

bathroom

B. A heating air supply, when the supply flows through an occupied

room.

C.

A window that can be opened and that is near an occupied

room, a

(**)

If the outlet is positioned at least 1 m higher than the intake supply opening, or a

window that can be

opened.

(***)

If the required distance cannot be achieved, the position of the outlet must

be

at least 1 m above the highest

facade/roof.

Important note for Roof Terminations,

(C31).

When installing the appliance with a roof termination (classification C31), it

is

important to fit a 30mm flue restriction strip across the flue outlet inside the stove.

COMMISSIONING THE

STOVE

A soundness test MUST be made before the installed stove is left with

the

customer.

Ensure that the fire is burning at full rate for a minimum of 5 minutes to warm

the flue. If there are

problems,

the flue may require

attention.

The stove will produce an odour and/or smoke for the first few hours of use.

Please

ventilate the room. Also please note that during this initial burning

period, a grey

dust deposit will be formed on the inside of the glass, please clean this

before

leaving the appliance with the

customer.

To avoid adverse effects

11

Ortal Technical Guide December 2015

For model size 150 and over it is recommended that the glass is handled by 2 people. Use appropriate glass suction cup lifters where necessary, support with gloved hands as much as possible. Place the glass on a sheet or soft surface to protect the edges. When replacing glass the retaining screws should be ‘finger tight plus a quarter turn’. Do not over tighten or the glass may crack.

For TS, LS, RS and Island models

When the glass is finally assembled ensure the glass to glass joints are pushed together before tightening the retaining screws and cold. It is recommended that a thin smear of high temperature silicone sealant is used on the glass to glass joints: Place masking tape down the edges of the adjoining glass to protect the faces, smear a small amount of silicone to seal the joint, wiping away excess so only a small film fills

the corner of the joint and remove tape before operating the fire. At service this film can be carefully cut with a sharp thin blade, taking care not to damage the glass edges. On reassembly the sealing procedure is repeated.

SERVICING INSTRUCTIONS

The following outlines only the minimum work that should be performed on an

annual basis. This service work, like any other work on the appliance, must only be done by a qualified and competent engineer who is Gas Safe registered. Open the door and remove all ceramics.

Remove any debris from the top of the burner using a vacuum cleaner and brush. Inspect the burner unit.

Perform an ignition check. Perform a flame failure check

There should be no need to service the burner. If however this is required, then the

engineer should check the setting pressure at the gas valve. Brush off and replace ceramic arrangement as shown in this manual, replacing any

broken or damaged pieces.

Check all seal on door (including glass) and refit the door. See ‘Commissioning the

Stove’

Check the installation for gas leaks.

Check the flue joints are secure, including those in voids, and that the flue is working satisfactorily.

Check that there are no flue products leaking from the appliance.

If

any parts need to be replaced use only genuine manufacturer parts, non-standard

parts will invalidate the guarantee and may be dangerous.

If you wish to install a flat screen television or similar electronic device above your Ortal gas fire, here are some things you should consider.

Most TV manufacturers have specified in their instructions that the TV should not be installed on, near or above a heat source. Ultimately, the decision of the TV location rests solely with the house holder. Robeys and Ortal will not be held liable for any adverse affects on a TV or other equipment located near to the fire.

These drawings are suggestions as a guide to reduce temperatures for those consumers who decide to locate their TV’s above the fire.

For the 110 & 130 models, the 100/150 size flue is most suited to straight vertical or vertical with up to 3m horizontal flue arrangements. For more complex flue arrangements it is recommended that the 130/200 flue size is used.

To use a 100/150 flue a USVK10 13 reducer will be required. This must be installed above the USA adaptor.

Ortal Flue Design Options

The permitted flue configurations and flue restrictor sizes are as shown in the tables. V = total vertical height H =total horizontal distance X = configuration not permitted There should be a minimum of 1m vertical connected to the fire before any bends. The only exception to this is for a vertical flue and termination, where it is permissible to connect 2 x 45 degree bends directly to a USA adaptor above the fire to offset the flue. The maximum offset in this condition is a horizontal distance of 0.5m

Additional Bends

It is permitted to add 2 additional bends to form an offset but this reduces the available maximum horizontal distance. The bends can be 2 x 45 degree*, 2 x 30 degree or 2 x 15 degree bends. * The bends cannot be put together to form a 90 degree bend.

When referring to the flue/restrictor tables add 0.5m for each additional bend to the measured horizontal flue length to give an equivalent length, check this is permitted from the tables. See example below. If the offset is in a horizontal section of the flue it can offset in either horizontal or vertical (upwards only) plane. 90 degree bends are not normally permitted in the horizontal plane i.e. both inlet and outlet ends are horizontal unless specifically approved through Robeys Technical Department at the planning stage before installation.

Calculation Example

These are typical configurations, however other flue configurations may be permitted on a case by case basis. If you have a special configuration contact Robeys Technical Department to discuss a solution. If the flue configuration falls outside the limits then consideration should be given to using a concentric fanned flue system.

Example: Clear 110 model using 130/200mm flue

Total vertical height (V) = 2m

Horizontal (H) = 3m actual + 1m (2 x 45° bend @ 0.5m per bend)

= 4m total equivalent horizontal

Refer to table,

V =2m with H =4m is permitted with the use of a 50mm flue restrictor

V = 2m total

H = 3m total

Troubleshooting

The gas pilot will not ignite or stay lit?

Ensure the gas is turned on at the appliance and the meter/cylinder. Depress the control knob for at least twenty seconds once the pilot is alight to ensure the operation of the safety thermocouple valve. Ensure that the pilot injector is not obstructed or blocked and it is free from any dust or dirt. Ensure that the thermocouple has not been damaged in transit. This is a very delicate Electro-magnetic device. On propane, the cylinder could be empty.

The pilot is not burning or performing correctly?

Ensure the pilot flame is the correct size for the type of gas. The flame should be focused on the thermocouple probe. The pilot flame will have been set correctly in the factory.

The Main Burner does not seem to be burning correctly?

Ensure adequate gas pressure to the appliance. Test pressure by releasing the pressure test screw and applying a manometer. Ensure adequate volume of gas is being used. Once the fire is burning on maximum, turn off all other gas appliances in the house and calculate the fuel being burned from the gas meter. Make sure that the burner is burning correctly. The flame should be even across the top of the burner before any coals are placed on top.
