TRIO - INSTRUCTION FOR INSTALLATION
1. Introduction
The Trio is a freestanding atmospheric gas heating appliance. This version of the Trio is suitable for natural gas. It is
not possible to make the appliance suitable for a different type of gas by using a so-called conversion set.
The Trio is a closed appliance. A closed appliance does not extract the combustion air from the living environment,
but from outside. This is done through a combined fl ue gas discharge system / combustion air supply system. In
this concentric system the outer pipe serves as air supply and the inner pipe as fl ue gas discharge.
This system can be installed through the wall, or through the roof.
The concentric system can be supplied in the colour of the appliance.
The appliance is supplied with a wireless remote control that works on batteries.
2. CE Declaration

essential requirements of the Gas Appliance Directive.
This declaration will lose its validity if adjustments are made to the appliance, without prior written permission by
DRU.

Place the appliance as follows:
Caution
- Always place the appliance and/or the discharge
pipes at a minimum distance of 500 mm from combustible objects or materials;
- Do not make any changes to the appliance.
➠
Determine the location of the appliance; the dimen-
sions can be found in
Fig. 1;
➠
Provide a gas connection at the location. For details,
see section 6.3;
➠
Make a duct for the ue gas discharge/combustion
air supply system with the following diameters. For
details, see section 6.5.

TRIO - INSTRUCTION FOR INSTALLATION
➠
Place the appliance on its destined location.
Caution
- Place the appliance at a distance of at least 40 mm from the back wall;
- Do not cover the appliance and the discharge material and/or do not wrap it in an insulation blanket or any other
material.
6.5 Flue gas discharge / combustion air supply system
6.5.1 General
The appliance is of the C11/C31 type.
The appliance is connected to a combined fl ue gas discharge/combustion air supply system, hereafter 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 section 6.5.3).
If necessary, you can also use an existing discharge channel (see section 6.5.4).
Caution
- Only use the concentric system supplied by DRU (Ø100 / Ø150 mm). This system was tested in combination with the
appliance; DRU cannot guarantee a proper and safe 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 DRU.
The concentric system is constructed from (the discharge stump of) the appliance.
If structural circumstances require that the concentric system is placed fi rst, the appliance can later be connected
with a telescopic pipe piece.
!Tip
DRU does not recommend placing the telescopic piece, because this visible pipe piece cannot be supplied in colour
and does not really combine well with the appliance.
6.5.2 Application with wall duct
6.5.2.1 Construction of concentric system with wall duct
The concentric system with wall duct has to comply with the following conditions (see Fig. 2):
- 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;
- On the vertical part a bend of 90° is connected;
- The total horizontal pipe length can have a maximum of 3 meters (wall duct excluded).
Under these conditions, the baffl e should be set to 65 mm (see section 6.7); the air inlet guide will not be placed.
6.5.2.2 Placing concentric system with wall duct
Place the concentric system as follows:
➠
Build the system up from (the connection stump of ) the appliance.
Caution
- Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling;
- Use heat-resistant isolation material when passing through combustible material;
- The rosette (mounting inner plate) of the wall duct is too small to seal the Ø 250 mm opening when passing through
combustible material. That is why you should rst apply a su ciently large heat-resistant intermediate plate to the
wall. Then, the rosette is mounted on the intermediate plate.
!Caution
Some heat-resistant isolation materials contain volatile components that will spread an unpleasant smell for a pro-
longed time; these are not suitable.
➠
Remove the top plate from the appliance; this plate is loose;
➠
Remove the cover plate by unscrewing the 2 parkers (see Photo 1);
➠
Place a lacquered pipe piece on the appliance;
➠
Apply a lacquered clip binding with silicon sealing
ring onto the connection between appliance and
pipe piece;
➠
Re t the cover plate with the 2 parkers;
➠
Place the top plate carefully onto the appliance, so
that the lacquered pipe piece will not be damaged;
➠
If necessary, connect the vertical (lacquered) concen-
tric pipe pieces;
➠
Connect the lacquered bend;
➠
If necessary, connect the horizontal (lacquered) con-
centric pipe pieces;
➠
On each connection, apply a (lacquered) clip binding
with silicon sealing ring;
➠
Use a parker to x the clip binding to the pipe on lo-
cations that are unreachable after installation;

TRIO - INSTRUCTION FOR INSTALLATION
➠
Apply su cient clamps, so that the weight of the pipes does not only rest on the appliance;
➠
Determine the remaining length of the wall duct;
➠
Make sure the wall duct has the right dimensions.
!Caution
- 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
from entering.
➠
Mount the rosette (mounting inner plate); if necessary, on a heat resistant intermediate plate when passing through
combustible material;
➠
Attach the wall duct from the outside with four screws in their respective holes.
6.5.3 Application with roof duct
6.5.3.1 Construction of concentric system with roof duct
The 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.
Depending on the construction, the appliance is set by means of the baffl e and/or the air inlet guide.
In the following procedure you can see how the allowability of a concentric system can be determined and which
settings are needed.
➠
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.
These data will help you determine whether the concentric system is allowed by using Table 1 for G25 and Table 3
for G20.
In Table 2 you can read for G25 and G20 which setting is required for the appliance.
Follow the procedure described below:
➠
In the rst 2 columns of Table 1/Table 3, search the number of bends required and the total horizontal pipe length:
➠
In the 3rd column of Table 1/Table 3, search the total vertical and/or sloping pipe length.
If you end up in a box with the letter A, B, C, D or E, 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 guide (for placing/setting see section 6.7).
Examples G25
To clarify, we will give 2 examples for Gas 25, to determine the allowability of a concentric system and the conditions
for setting the appliance.
In Table 1 the route to be followed is indicated by arrows. The result is indicated by an underlined letter (= allowed)
or a dash “-“ (= not allowed).
Example 1
1) 2 bends
2) 3 meters horizontal
3) 8 meters vertical/sloping
→ Construction of this concentric system is allowed.
→ Situation D applies for setting the appliance
Example 2
1) 3 bends
2) 4 meters horizontal
3) 9 meters vertical/sloping
→ Construction of this concentric system is not allowed.
