qualit

y

, performance and safety requirements

.

As a result of which the user is able to enjoy using your appliance for years to come

.

This appliance is CE marked; it complies with the essential requirements of the European Appliance Directive.
The a

pp

liance is supplied with two manuals: the installation manual and the user manual.

You the installer should be professionall

y

skilled in the fi eld of decorative gas heatin

g.

The installation manual gives you all the information you will need to be able to install the appliance in such a way
that it works correctl

1. Introduction

T

he appliance is available in two models, the Largo and the Largo Tunnel

.

T

he Largo is a ‘standard’ gas fi re and should always be installed against a wall. The Largo Tunnel is just that, a ‘tunnel

fi

re’ with both a front and back window.

T

he Largo and the Largo Tunnel are closed decorative fi res. A closed tunnel draws its combustion air from outside and
ot from the living area. This is done by way of a combined system that discharges the fl ue gases and supplies the

c

ombustion air. In this concentric system the outer pipe serves as air supply and the inner pipe as the fl ue

.

T

his system can be installed through either the outer wall or the roof

.

T

he appliances are built into a chimney breast. The DRU product range includes several chimney breasts

.

Th

e chimney breast must be well ventilated to ensure a good heat distribution. DRU can supply various ventilation

elements

.

T

he appliances are supplied with a wireless, battery-operated remote control

.

.5.1 Genera

l

The appliance is of the C11/C31 type

.

The appliance is connected to a combined fl ue gas
dischar

g

e/combustion air supply system, hereafte

r

referred to as the concentric system

.

The passage to the outside can be made with a wall
duct

(

see section 6.5.2) or with a roof duct (see sec

-

tion 6.5.3)

.

If necessary, you can also use an existing discharge
c

h

annel (see section 6.5.4

).

N.B.

- Only use the concentric system supplied by DRU

(

Ø100 / Ø150 mm). This system was tested in com-

b

ination with the appliance; DRU cannot guarantee

a proper and sa

f

e operation of other systems and

cannot accept liability for these systems

;

-

For connecting to an existing chimney  ue you

should only use the installation set supplied by

DR

U.

The concentric system is constructed from (the di

-

scharge stump of) the appliance

.

If structural circumstances require that the concen

-

tric system is placed fi rst, the appliance can later be
connecte

d

with a telescopic pipe piece

.

all duc

t

The concentric system with wall duct has to comply
with the

f

ollowing conditions

:

➠

First, a concentric pipe of at least 1 meter should be connected vertically to the appliance;

➠

The total vertical pipe length can have a maximum of 4 meters

;

➠

After the vertical part a bend of 90° is connected

;

➠

When using a minimum 1 up to maximum 4 meter vertical pipe length, the total horizontal pipe length may have a

m

aximum of 3 meters (wall duct not included; see Fig. 4a).

Depending on the construction of the concentric system, further adjustments should be made to the appliance.
The next 2 con

fi g

urations are allowed for the construction

:

1) a minimum 1 meter up to maximum 4 meter vertical pipe length in combination with a 90° bend and a wall duct (i.e.
no horizontal

p

art; see Fig. 4b

).

- When using this confi guration, you must not remove the air inlet guides

;

- When using this confi guration, you must not set the restriction.

2) a minimum 1 meter and maximum 4 meter vertical pipe len

g

th in combination with a 90° bend and a maximum

3 meter

h

orizontal pipe length and a wall duct (see Fig. 4a).

- When using this con

6.5.2.2 Installing the concentric syste

m

T

o install the concentric system commence as follows

:

➠

Construct the system from the (connection stub of the) appliance up

.

N.B.

- Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling;

I

f the system is built-into a cove for example, incombustible material should be applied all around

;

- Use heat-resistant insulating material for ducts made of combustible material

;

- The rosette (mounting inner plate) of the wall duct is too small to seal the Ø 250 mm opening when passing through

c

ombustible material. That is why you should  rst apply a su ciently large heat-resistant intermediate plate to the

wa

ll

. Then, the rosette is mounted on the intermediate plate

.

➠

Connect the concentric pipe sections and the bend(s);

➠

Fit a clamping strip and silicone sealing ring to every connection

;

➠

Secure the clamping strip with a self-tapping screw in places which will be inaccessible after installation;

➠

Use enough brackets to ensure that the weight of the pipes does not rest on the appliance;

➠

Determine the remaining length of the wall duct

;

➠

Cut the wall duct to size

;

!

N.B.- Make sure that the right insertion length is maintained

;

- Place the wall duct with the groove/folded seam at the top;

- Make sure the horizontal concentric pipe pieces are sloping towards the wall duct, in order to prevent rain water

f

rom entering.

➠

Mount the rosette (mounting inner plate); if necessary, on a heat resistant intermediate plate when passing through

c

ombustible material

;

➠

Attach the wall duct from the outside with four screws in their respective holes

.

!

N.B. Some heat-resistant isolation materials contain volatile components that will spread an unpleasant smell for a pro-

l

onged time; these are not suitable

.

6.5.3 Application with roof duc

t

6.5.3.1 Construction of concentric system with roof duc

t

T

he concentric system with roof duct has to comply with the following conditions

➠

The construction of the chosen system has to be allowed. (See the procedure described below)

;

➠

First, a concentric pipe of at least 1 meter should be connected vertically to the appliance

.

epending on the construction of the concentric system, the appliance is set by placing the baffl e and/or removing

t

he air inlet guides

.

n the following procedure you can see how the allowability of a concentric system can be determined and which

s

ettings are neede

d.

➠

Determine the following data:

1

. The number of bends required (no distinction is made between 45° and 90° bends

);

2

. The total number of meters of horizontal pipe length

;

3

. The total number of meters of vertical and/or sloping pipe length (wall duct not included)

.

With th

ese data and Table 1 you will be able to determine whether the concentric system is allowe

d.

n Table 2 you can see which setting the appliance needs

.

ollow the procedure described below

:

➠

In the  rst 2 columns of Table 1, look for the number of bends required and the total horizontal pipe length

;

➠

In the 3rd column of Table 1, look for the total vertical and/or sloping pipe length.

f you end up in a box with the letter A, B, C or D the concentric system chosen by you is allowed.

➠

Use Table 2 to determine which conditions apply for the ba e and/or the air inlet guides (for setting see section 6.8);
