Do not mix different types of antifreeze. The addition of anything which may interfere with the Trianco cannot be held liable for damage caused to normal operation of the boiler without the written the boiler or water system as a result of the incorrect permission of Trianco Ltd could invalidate the use of antifreeze or other additives.
INSTALLATION AND ASSEMBLY The appliance must only be installed on sealed 3.2 UNIT ASSEMBLY heating systems. The boiler must be installed in a position complying Do not use galvanised radiators or pipework, as this with the dimensions set out in section 3.1. will lead to the formation of gas in the system.

ACCESS TO THE INSIDE OF THE BOILER To gain access to the combustion chamber, proceed as follows: 1) Remove the two screws from the underside of the control panel (fig 13) and bring forward, pulling from the top. 2) Remove the two screws behind the control panel. 3) Lift the front door upwards and then forward to remove.
ELECTRICAL Always isolate the power supply to the appliance before carrying out any work on the electrical systems and components. Wiring to the boiler must conform with all requirements of the current issue of the IEE Wiring Regulations for fixed wiring to a stationary appliance, and any local regulations which may apply.

5.3 CONTROLS & WIRING Combi (CB) Model System (SB) Model The boiler should be connected to a double-channel The boiler should be connected to a double-channel programmer with volts-free switching to allow the programmer with volts-free switching to give the control of the central heating and hot water.
Only Trianco flues are permitted for use on this Please refer to the Trianco catalogue for a full list of appliance. Correct operation of other manufacturers’ available flues and configurations. flues on the boiler cannot be guaranteed.

6.17 ALTERNATIVE FLUEING EXAMPLES When determining the flue length on non-typical flue courses, it is important to take into consideration that each additional elbow added to the run will dectract from the overall permitted flue length. A 90° elbow should be classed as reducing the length of the overall run by 1500mm. A 45°...

7.3 MODE FUNCTION – ADJUSTABLE PARAMETERS The MODE function (button ‘E’) and the ‘+’ and ‘-‘ programming control buttons (‘F’ and ‘G’) are for use by the installation/commissioning engineer during the initial set-up of the boiler running parameters. To read or set these parameters, first press the reset button (‘D’), and while this is still held, press the MODE button (‘E’) for at least five seconds.
7.4 MODE FUNCTION – INFORMATION PARAMETERS To access the information-only parameters, press and hold the MODE button (‘E’) for 15 seconds. Repeatedly pressing the reset button will cycle through the available parameters to view. To exit from this function, press the MODE button once more, or leave the reset, ‘+’...
details of other fault codes and general fault-finding, 7.5 FROST THERMOSTAT refer to section 13. To prevent damage to the appliance during very cold 7.9 ANTILOCK FUNCTION weather, it is advisable to fit an external frost thermostat to the installation, which will supersede the central heating and hot water settings to temporarily After 21 hours of inactivity, the pump will activate for activate the boiler should the temperature drop too...
10 COMBUSTION ANALYSIS The combustion analysis should be carried out in heating mode. While in this function, the boiler temperature limits are deactivated and the boiler will operate at the maximum setting of 88°C. However, should this be problematic (e.g. in summer), it is possible to use the domestic hot water circuit If the values are found to be inconsistent with these, (combi model only).

11 PROPANE CONVERSION To convert the boiler from natural gas operation to propane, the following steps must be carried out: 1) Isolate the electrical supply to the appliance. 2) Close the gas supply to the appliance. 3) Gain access to the internal sealed chamber of the appliance, following the directions on page 16.
12 SERVICING AND MAINTENANCE To ensure safe and efficient operation of the Clean the condensate trap by unscrewing the appliance, the boiler must be serviced at least once a plastic cover on the underside of the boiler. Check year by a CORGI-registered engineer. Failure to do so inside for deposits and clean as necessary.
12.2 BURNER & HEAT EXCHANGER SERVICING Ensuring that both the electrical supply and gas supply to the boiler are isolated, disconnect the gas pipe (item 1, fig 46). Remove the 2 x nuts (2) and remove the manifold (3). Disconnect the air pipe and electrical connections from the fan.
13 FAULT-FINDING After an appliance malfunction, the boiler will enter a lock-out state (indicated by the illumination of LED ‘H’). The multifunction display will show a three-digit fault code. In most cases, the fault can be eliminated by switching the boiler off then on, using ON/OFF button ‘A’.
If the problem persists, refer to the following fault-code chart: If in doubt, fully-trained Trianco technical operatives are available to help you with any on-site need. For technical advice, call 0114 257 2300 (Monday-Thursday: 08:30 – 16:45, Friday: 08:30 – 14:30).
14.1 CONTROLS CONNECTION PLUG On the System (SB) Model only, this item is used to connect external controllers to the boiler. See wiring diagram (section 5.6, fig 24) for correct placement. Using a crimping tool, attach the external control wiring to the terminals provided and insert into the plug provided. Connect as shown FIG.
