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 flue gas discharge system / combustion air supply system. In
this concentric system the outer pipe serves as air supply and the inner pipe as flue 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
Internal precautions at the company will guarantee that appliances produced by DRU comply with the essential
requirements of the regulation concerning gas combustion appliances and the standards applied for that purpose.
This declaration will lose its validity if adjustments are made to the appliance, without prior written permission by
DRU. A copy of the CE test certificate can be downloaded via www.druservice.com.

6.5 Flue gas discharge / combustion air supply system
6.5.1 General
The appliance is of the C11/C31/C91 type.
The appliance is connected to a combined flue 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 first, 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 Appendix 4, 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 you should not install the restrictor slide; 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.

control works.
!Caution Do not ignite the appliance before the gas and discharge connections have been fully installed, rst observe the pro-
cedure described in chapter 8.3.
Below, we will describe how the receiver is connected.
7.1 Receiver
The receiver should be connected to the appliance, before the batteries are installed.
Follow the procedure below (see Appendix 4, Fig. 21):
➠
Slide the brown plug of the connecting cable onto the back of the receiver’s printed circuit board.
➠
Connect the white plug to the gas control block.
!Tip The plugs have dierent sizes that correspond with the connectors.
➠
Connect the cables of thermocouple 1 to the receiver; (see Appendix 4, Fig. 21, arrow B).
!Tip - The size of the eye corresponds with the size of the screw;
-The colours of eye and screw also correspond.
➠
Connect the ignition cable to the receiver; (see Appendix 4, Fig. 21, arrow A).
➠
Connect power:
a) When using batteries, see section 7.1.1 below;
b) When using an adapter:
- connect it to the receiver; (see Appendix 4, Fig. 21, arrow C);
- insert the plug into the wall socket.
➠
Place the receiver in the control box, as indicated on Fig. 22 (o), see Appendix 4.

7.1.1 Placing / replacing the batteries
Follow the procedure below when placing the batteries:
➠
Open the door of the stove.
➠
Pick up the receiver.
➠
Slide the cover o.
➠
Place or remove the 4 penlite (AA type) batteries.
!Caution - Avoid a short circuit between the batteries and metal objects/parts;
-Observe the “+” and “-” poles of the batteries and the holder;
-Use alkaline batteries.
➠
Slide back the cover.
➠
Place back the receiver.
!Caution Batteries are regarded as “small chemical waste” and may therefore not be disposed with the household rubbish.
7.2 Setting the communication code
Prior to putting the application into operation, a communication code must be set between the remote control
and the receiver. If the receiver or the remote control are replaced, a new code will have to be set.
Follow the procedure described below:
➠
If necessary, place the batteries in the receiver’s battery holder; see section 6.1.1.
➠
If necessary, place the 9V block battery in the remote controle; see User Manual.
➠
Hold down the reset button on the receiver, until you hear two consecutive sound
signals (see Appendix 4, Fig. 24).
➠
After the second, longer signal, let go of the reset button.
➠
Press the ‘small ame’ button on the remote control for 20 seconds, until you hear two short sound signals: this is the
conrmation of a good communication.
7.3 Alternative operation
Appliances made with an electronic ignition and radio remote control can be connected to an alternative external
control system (e.g. Domotics). For this purpose, there are 4 connection points at the side of the receiver (see Ap-
pendix 4, Fig. 20). For connecting an external control unit, you will need a “Domotics connection cable for GV60”.
Consult DRU’s service website.
The following contacts are possible:
- Ignition: connect both contacts 1 + 3, for one second (if there is a 2nd thermocouple, the appliance should burn
at full power for at least 20 sec. before the required position can be chosen).
- Flame high(er): briefly close contact 1 once per step, or 12 seconds for the highest position.
- Flame low(er) until switch-off (pilot flame remains on): briefly close contact 3 once per step, or 12 seconds for the
lowest position.
- Completely switching off the appliance (pilot flame included): close all three contacts 1 + 2 + 3, for one second.
The appliance will always continue to respond to the radio remote control supplied with it. The external control
system is able to use one of the two modes of this remote control.
1. Manual mode
This mode of the remote control is passive and will not take any action unless it is operated. The external control
system is able to control the functions for high/low position, ignition and switching off.
!Tip If the external control system has an intelligent clock function and/or thermostat function, the remote control sup-
plied with the appliance should have the manual mode in order to prevent interruption of these functions.
2. Clock/thermostat mode
This mode of the remote control is active and will be responsible for the clock function and thermostat function.
The external control system is able to control the functions for high/low position, ignition and switching off.
!Tip - If the appliance is switched o (the pilot ame included) manually or by one of the safeguards, ignition of the ap-
pliance will be blocked for a period of 3 minutes for reasons of safety.
-If it is no longer possible to operate the appliance with the external control system, you must switch it o and then
switch it on again with the supplied remote control.
