A warm welcome to Contura

A warm welcome to the Contura family. We hope you will

get a great deal of pleasure from your new stove. As a new

owner of a Contura stove you have secured a product

with timeless design and long service life. Contura also

has combustion that is both environmentally friendly and

eﬃcient for the best heat production.

Read through these installation instructions carefully before

installation. Read how to best light your stove in the lighting

instructions.

NOTE!

Report the installation of a stove to your local authority

The owner of the house is personally responsible for ensuring compliance with the mandatory safet y requirements and must have the installation approved by a qualified inspector. Your local chimney sweep must also be informed about the installation as this will affect the routines for regular chimney-sweeping services.

WARNING!

The stove becomes very hot

During operation, certain sur faces of the stove become very hot and can cause burn injur y if touched. Be aware of the strong heat radiated through the hatch glass. Placing flammable material closer than the safe distance indicated may cause a fire. Pyre lighting can cause quick gas ignition with the risk of damage to property and personal injury.

Building application

Before installing a stove or erec ting a chimney it is necessary for you to make a building application permission to your local authority. Ask your local authority for advice regarding building regulations and the application.

Structural support

If the hearth is to be positioned on a wooden joist, a structural engineer should evaluate the load capacity of the floor. When the gross weight exceeds 400 kg, reinforcement of the wooden joists is usually necessary.

Hearth plate

If the floor under the hearth is flammable, it must be protected by a non-flammable material which covers at least 300 mm to the front and 100 mm on each side. The hear th plate can consist of natural stone, concrete or 0.7 mm thick metal. A painted metal or glass hear th plate is available as an accessory.

Chimney

The insert requires a draft in the chimney of at least –12 Pa. The draft is affected both by the length and area of the chimney, and by how well sealed it is.

• Once the lighting phase is complete, this inser t must be operated with the door closed because of the risk of smoke entering the room. Always open the door carefully and slowly to prevent blow back because of the changing pressure in the stove.

• Carefully check that the chimney is sealed and that there is no

leakage around soot hatches and flue connections.

Note that a flue with sharp bends and horizontal routing reduces the draught in the chimney. Maximum horizontal flue is 1 m, on the condition that the vertical flue length is at least 5 m. It must be possible to sweep the full length of the flue and the soot hatches must be easily accessible.

Wall behind

If your Contura 11 / 21 is to be installed against a flammable wall the

wall must be protected by a firewall or by the integrated protective screen that is sold an as accessory for these models. A firewall must be at least the same width and height as the surround. More information about the requirements made of the fire wall material is available in the separate instructions for the insert. Remember that non-flammable walls can also require protection if they are bearing walls or have flammable material behind them.

Concrete

The surface of concrete, by it s nature, is not free of defec ts. In order to achieve a neat end result some of the concrete may need to be filled and sanded. If greater damage occurs to the concrete it can be repaired by mixing water with the cement powder supplied and filling the holes.

Because of the settling in buildings and the fact that concrete shrinks, cracks may occur in the grouting between the block s in the first few months. Scrape out the grout and brush the surfaces clean. Fill with new grout and paint over when dry.

General

This manual contains instructions about how the Contura 11 and 21

must be constructed and installed. More information about the insert is available in the separate installation instructions. To ensure the function and safety of the hear th, we recommend that installation is carried

out by an authorised technician. Our Contura dealers can recommend

suitable technicians, information about our dealers can be found at www. contura.eu

Instructions for lighting are also supplied with the insert. Read them carefully and keep them safe for future use.

The hear th is type approved in accordance with EN 13240 and must be

connected to a chimney dimensioned for a flue temperature of 350°C, the external connec tion diameter is Ø200 mm. Supply of combustion air

from the outside must be arranged, see page 42.

FACT S

Knockout

To insert the combustion air hose through the base plate, tap out the knockout from the concrete using a hammer, remember to protect the floor.

Supply of combustion air

Combustion air can be provided directly via a duct from outside, or

indirectly via a vent in the outer wall of the room where the stove is to be placed. The amount of combustion air used for combustion is

approximately 30 m³/h (applies with closed hatch),

Some installation alternatives are shown to the right. The air duct

connection on the stove has an ex ternal diameter of Ø100 mm.

In hot areas the duct should be insulated with 30 mm mineral wool covered with a moisture inhibitor (aluminium tape). It is impor tant that the lead-in between the pipe and the wall (or floor) is sealed using jointing compound.

A 1 m length of condensation insulated ducting for combustion air is available as an accessory.

INSTALLATION DISTANCES

Selection of chimney connection and material in the wall behind mean that different requirements are made of installation. Note that a non-flammable wall or firewall must meet the requirement s stated on page 41. In other cases the accompanying protective screen must be used.

Installation alternatives

Non-ﬂammable wall / Firewall

If the wall behind is non-flammable or protected by a firewall the surround can be installed directly against it. The small, 100x15 mm, air intakes in the protective screen on the surround sides can be filled if so desired. Top and rear connection can be made without any extra insulation or screening of connection pipes.

Protective screen

When the surround is installed together with the integrated protective screen it is important that the airflow is not blocked. For top connection, the gap between the top of the surround and the chimney insulation must be covered by a cuff to shield the radiant heat from the start pipe. It is also possible to connect to the rear through the protec tive screen, on the condition that a fully insulated chimney is used and the necessary safety distances observed. Ensure that there is a seal between the chimney and the protective screen.

Standard surround

CHIMNEY

Non-ﬂammable wall / Firewall

When the height ex tension section is installed in the integrated protective screen, the air outlet at the top of the surround nearest to the wall must be sealed and the whole top sur face insulated. It is also possible to connect the chimney with a backward angle through the height extension section that requires a seal above the angle.

Protective screen

When the height ex tension section is installed the protective screen must be extended with a heat deflec tor through the height extension section. Ensure that the heat deflector is also ventilated. The top of the surround is also insulated using the insulation sheet provided.

CHROME

On aluminium and steel fronts there are adjustment screws that can be used to adjust the front panel by height. When the front panel is set the outer Torx screws are screwed until they support against the concrete. The top rests on the turned down angles at the rear edge, these can be adjusted to get the top to the level of the concrete.

When installing the height extension section:

• with an integrated protective screen, go to page 58.

• in combination with a non-flammable wall and

chimney connection straight backwards, go to page 62.

• in combination with a non-flammable wall and

chimney connection angled backwards through the height ex tension section, go to page 65.

For installations without height extensions, top connection to stainless steel flues is now possible; follow the chimney manufacturer ’s instructions. Then continue on page 57 with joining and painting.

Final inspection of the installation

Before the stove is used, it must be inspected by an authorised chimney sweep. Read the “Instructions for

Lighting the CI 10 / CI 20 series” before lighting the fire for the first time.

ASSEMBLY

The gap between the concrete and the wall behind can be grouted if so desired. It is important that the air inlet, 100x15 mm, at the bottom of the section two is not blocked if the integrated protective screen is installed. If the surround is installed against a normal firewall the air intake can be blocked if so desired.

When the paint is dr y the grilles can be installed. The top grilles* are placed in position on the upper side, and the lower grille pins are installed using the springs and lugs supplied. * (not used when installing the height extension section).

Even off the edges between the concrete blocks by applying a little grout in the joint s and then using the corner of a filling knife to scrape out the excess and retain the marked edges.

Fill and sand small scratches and pores in the concrete. As soon as the silicone, grout and any repairs to the concrete are dry the surround can be painted with a silicate paint.

ASSEMBLY

Install the protective screen according to the separate instruction and the surround at ordinar y height according to page 47-56. Then apply silicone to the top of the surround and lift up the concrete sides of the height extension section. Support the first side so that it does not fall while the other side is installed.

Hang the safet y rail between the sides and ensure

that they are straight. Check that the width is the

same as section 1 at the front and rear edges.

Note the different installation methods of the height extension section. When using a protective screen the airflow must not be restricted at any point.

ASSEMBLY

Install the right half of the heat deflec tor by inserting sideways and hooking the tabs around the concrete. Note that the heat deflector at the bottom edge must be positioned in front of the protective screen’s heat deflector.

Install the lef t half of the heat deflector in the same way, and screw the two halves together.

ASSEMBLY

For top connection

Check that the measurement between the top and the

chimney mantle is 25-30 mm. Then position the small insulation plate over the chimney hole in the top and connect the chimney. The chimney must press the insulation together approx 5 mm so that it is tight, but the weight must be on the insert and not the top panel. If the start pipe has a diameter greater than 150 mm the hole in the insulation must be cut out to fit.
