3 Installation

Warning

Installation work should be carried out by an approved installation engineer in compliance with the general and local regulations imposed by the gas, water and power supply companies and the fire service.

The appliance may only be installed in a room that complies with the requirements stated in national and local ventilation

regulations (1.3 "Regulations").

3.1

Introduction

This chapter describes the installation activities to be carried out before you

 

 

actually start using the appliance (9 "Starting and running"), namely:

 

 

•

Packaging;

 

 

•

Environmental conditions;

 

 

•

Technical specifications;

 

 

• Water connections, Vented;

 

 

• Water connections, Unvented;

 

 

• Water connections, Vented;

 

 

•

Gas connection;

 

 

• Solar heating system;

 

 

• Air supply and flue;

 

 

•

Electrical connection;

 

 

• Checking the supply pressure and burner pressure.

For conversion to a different gas category, see conversion (4 "Conversion to a different gas category").

3.2

Packaging

To avoid damaging the appliance, remove the packaging carefully.

 

 

We recommend unpacking the appliance at or near its intended location.

 

 

 

 

 

Caution

 

 

The appliance may only be manoeuvred in an upright position. Take care

 

 

that the appliance is not damaged after unpacking.

3.3

Environmental

 

The appliance is suitable for either open or room-sealed combustion. If

 

conditions

installed as a room-sealed appliance, then the availability of the necessary

external air supply will depend on the place of installation. In this event, there are no additional ventilation requirements.

If the appliance is to be installed as an open system, then it will be subject to the guidelines and ventilation regulations that are in force locally.

The alternative installation types are B23, C13, C33, C43, C53 and C63.

Caution

The appliance may not be used in rooms where chemical substances are stored or used, due to the risk of explosion and/or corrosion of the appliance. Some propellants, bleaching agents, degreasing agents etc. disperse vapours which are explosive and/or which cause accelerated corrosion. If the appliance is used in a room in which such substances are present, the warranty will be void.
