DESCRIPTION OF SYMBOLS WARNING Risk of damage to or malfunction of the appliance. Pay special attention to the warnings concerning dan- ger to people. DANGER OF BURNS Wait for the appliance to cool down before working on the parts exposed to heat. DANGER - HIGH VOLTAGE Live components - electrocution hazard. -
Page 4: General Precautions
GENERAL PRECAUTIONS This boiler has been designed to heat water to a temperature lower than boiling point at atmospheric pressure. It must be connec- ted to a central heating system and to a domestic hot water supply system according to its performance and power output. Before having the boiler installed by a qualified service engineer, make sure the following operations are performed: •... -
Page 5: Commissioning The Boiler
1. COMMISSIONING THE BOILER To light the boiler correctly, proceed as follows: • Check that the system pressure is correct (section 6); • Power the boiler; • Open the gas tap; • Select the required heating mode (section 1.2). During initial ignition, the burner may not ignite (causing the boiler to shut down) until any air in the gas pipes is vented. In this case, repeat the ignition procedure until gas reaches the burner. -
Page 6: Prolonged Shutdown. Frost Protection
2. PROLONGED SHUTDOWN. FROST PROTECTION Do not drain the whole system as filling up with water again could cause unnecessary and harmful scale to build up inside the boiler and the heating elements. If the boiler is not used during winter and is therefore exposed to the danger of frost, add some specific anti-freeze to the water in the system (e.g.: propylene glycol coupled with corrosion and scale inhibitors). -
Page 7: Filling The System
6. FILLING THE SYSTEM The pressure displayed on the pressure gauge has to be between 1 - 1.5 bar, with the system cold. If it is lower, turn the system filling tap installed by the fitter. IMPORTANT: open the tap very slowly in order to vent the air. The boiler is fitted with a hydraulic pressure switch which prevents the boiler from working if there is no water. -
Page 8: Instructions Prior To Installation
The boiler is supplied without the circulation pump. This component must be installed on the heating return to allow water to circu- late between the boiler and the low loss header and can be purchased off the shelf or supplied by POTTERTON COMMERCIAL as an accessory (modulating pump). -

TABLE 1A ∆P (Pa) If the flue and air ducts installed are not supply by POTTERTON COMMERCIAL, make sure they are certitied for the type of use and WH 90 have a maximum pressure drop as indicated in the table to the side. -
Page 10: Electrical Connections
11. ELECTRICAL CONNECTIONS This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety re- gulations. Connect the boiler to a 230V single-phase earthed power supply using the supplied three core cable, observing correct Live-Neutral polarity. -
Page 11: Connecting The Room Thermostat
11.1 CONNECTING THE ROOM THERMOSTAT The connections in terminal block M1 are in high voltage (230 V). Before making connections, make sure the appliance is disconnected from the power supply. Check the polarity: L (LIVE) - N (NEUTRAL). To connect the Room Thermostat to the boiler, proceed as de- scribed below: •... - Page 12 KEY TO FIGURE MENU Enduser Engineer Commissioning ALL MODIFIED PARAMETERS SHOULD BE NOTED DOWN IN THE TABLE AT THE END OF THIS MANUAL (page 31).
