1. Introduction

Pronto is a suspended atmospheric gas heating appliance. This Pronto version is suitable for natural gas. The Pronto 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.

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).

Wall bracket

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 ﬂ ue you should only use the installation set supplied by DRU. Always place the concentric system at a minimum distance of 500 mm from combustible objects and/or materials Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling. If the system is built in (for instance) a cove, it should be made with incombustible material all around it.

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.

Check the ignition of the pilot  ame.

➠

the pilot ﬂ ame burner should start at the ﬁ rst attempt. If the pilot ﬂ ame does not burn:

Check if the ignition sparks:

➠

a) If not, the ignition cable is probably not lying free from metal parts; b) If it does, there is probably still air in the pipe.

Bleed the pipe and/or

➠

Lay the ignition cable free from metal parts.

➠

8.3.2 Main burner

Caution
