1  INTRODUCTION

1.1 Please carefully read the information in the

booklet to help you gain maximum if from your 

appliance with minimum trouble.

1.1.1 Your Ravenheat Condensing Combination 

Boiler has been designed to supply your Central 

Heating and Domestic Hot Water directly from one 

unit. When central Heating is operating, the 

circulation will be interrupted when domestic hot 

water is being drawn off. This will normally not 

affect the level of the heating.

1.2 CLEARANCES AROUND THE BOILER

Above 125mm     (5 inches)

Below 150mm     (6 inches)

Front   450mm     (18 inches)

Sides      5mm     (0.2 inches)

25mm (1 inch) at the front when installed

in a cupboard.

PLEASE NOTE

Due to the high effi ciency and resulting low fl ue  gas 

exhaust temperature a white plume of condensation

vapour (cool steam) will be emitted from the fl ue outlet

terminal, this is quite normal.  It will be particularly 

evident during periods of low outdoor temperatures or 

when the boiler is working at its optimum performance.

1.2.1 Minimum clearances are required for safety and 

maintenance.

Do not obstruct any purpose made ventilation opening 

if boiler has been fi tted in a compartment. Never hang 

clothes, etc., over the appliance.

1.3 USER CONTROLS

(See Fig. 1)

1.3.1 This appliance is designed to operate with the 

minimum of attention by the user.

All controls are to be found on the control panel.

1.4 OPERATING SAFETY CHECKS TO

PROTECT YOUR APPLIANCE

1.4.1 Before lighting the appliance check central

heating system pressure ( (7) is not less than 1 bar 

gauge. If it is below this do not light but consult your 

installer about refi lling your system as you may have a 

leak in the system.

1.4.2 A RED warning light on the control panel (8)

warns of a fl ame failure of the burner. This can be reset 

manually by pressing mains boiler on/off switch (1).

1.4.3 A RED warning intermittence light on the control 

panel (8) warns of a high temperature lockout on the 

overheat thermostat. This could occur due to air or poor 

circulation in the boiler/heating circuit. This can be reset 

manually by pressing mains boiler on/off switch (1). If 

lockout should persist leave the appliance shut down 

and consult your installer/service engineer

immediately.

1.4.4 The CSI SYSTEM AAA(T) 780 series condensing 

boiler is fi tted with a condensate outlet which must be 

connected by the installer to a suitable discharge point 

as specifi ed in the installation manual.

On no account should this discharge pipe be blocked 

or modifi ed.
