2 Safety • Do not make any alterations before: - to the unit, - around the unit, - to the gas, air, water and electricity supply lines, - to the expansion relief valve and drain line for the heating water, - to the flue gas pipes. This also applies to alterations to structural elements in the vicinity of the appliance which might affect its operational safety. For example: - Keep all openings for air and flue gas free.
Safety 2 Instructions for operation 3 2.3 Regulations For installation of the appliance laws, regulations, technical rules and standards must be considered and adhered to ensure the safe installation of your appliance. 2.3.1 Regulations (Great Britain and Eire) Attention shall be made to the regulations, guidelines and standards in force.
3 Instructions for operation 3.3 Requirements of the installation site Vaillant ecoCRAFT gas-fired condensing boilers must be installed in a boiler room. Ask your heating engineer which national regulations must be observed. The entire installation site should be frost-proof. Observe the specified frost protection measures in Chapter 2 if you are unable to ensure this requirement.
Instructions for operation 3 only inconvenient, it is also completely unnecessary, for a correctly functioning thermostatic valve will do all this by itself: if the room temperature rises above the value set on the sensor head, the thermostatic valve will close automatically; when the temperature falls below the set value it will open again. Do not cover thermostatic valves Do not cover the thermostatic valves with furniture, drapes or similar objects. The room air must circulate unhindered.
4 Operation 4 Operation 4.1 9 Overview of the operating controls 1 2 9 Rotary knob for setting the storage tank temperature (on units with the VIH domestic hot water cylinder connected ). When using the VRC 430 for controlling the cylinder temperature, set the knob to the clockwise end stop so that the working range of the hot water regulator in the VRC 430 will not be restricted. Digital Information and Analysis System (DIA) 11 3 8 7 6 5 4 Fig. 4.
Operation 4 This operating mode can only be ended: - via vrnetDIALOG or - by altering the temperature setting on the rotary knobs (8) or (9) by more than ± 5 K. This operating mode can not be ended: - by pressing the "Fault reset" button (7) or - by switching the unit on or off.
4 Operation 4.3 Start-up 4.4 Hot water preparation For hot water preparation, a Type VIH domestic hot water cylinder must be connected to the boiler. 2 4.4.1 Setting the hot water temperature 2 3 1 Fig. 4.4 Switching on the appliance • Use the main switch (1) to switch the appliance on and off: 1: "ON" 0: "OFF" When you switch the unit on the display (2) shows the current heating flow temperature. To customise the settings in the unit, read Sections 4.4 and 4.
Operation 4 4.4.2 Deactivating the storage tank mode On units connected to domestic hot water cylinders, you can deactivate the hot water generation or recharging operation whilst keeping the heating system in operation. • Turn the rotary knob for setting the hot water temperature all the way to the left. Only the frost protection function for the cylinder remains active. h Note When using a VRC 430, turn the rotary knob to the clockwise end stop and switch the cylinder circuit to "Off" on the VRC 430.
4 Operation 4.5.3 Switching heating mode off (summer mode) 4.6 Status displays 1 Heizbetrieb - Bren 1 2 Fig. 4.8 Switching off heating (summer operation) Fig. 4.10 Status displays You can switch off the heating in summer without switching off the hot water supply. • Turn the rotary knob (1) for setting the heating feed temperature all the way to the left. 4.5.4 Adjusting the room thermostat or weather compensator 1 The status displays provide information on the operating status of the unit.
Operation 4 4.7 Troubleshooting Should problems arise while operating your gas condensing boiler, you can check the following points yourself: No hot water, heating stays cold; Appliance does not start: - Is your house stop cock in the gas supply or the gas stop on the appliance open (see Section 4.2.1)? - Is the power supply switched on? - Is the main switch on the gas-fired condensing boiler switched on (see Section 4.
4 Operation 4.7.4 Filling the appliance/heating system The filling pressure must be between 1.0 and 2.0 bar when the system is cold in order for the heating installation to operate properly (see Section 4.2.2). If it is less, have the water topped up by your heating engineer. If the heating system extends over several storeys, a higher filling pressure may be required. Ask your engineer for details.
Operation 4 4.9.3 Maximum output measurements h Note! The measurement and checking work described in this section are only carried out by your chimney sweep. 4.10 Maintenance and Customer Service 4.10.1 Maintenance Permanent operational readiness and safety, reliability and a long service life require inspections and maintenance work to be carried out annually by a heating engineer.
