IMPORTANT PRE-INSTALLATION NOTES
Before installation, it is imperative that the following guidelines are heeded to ensure the trouble-free and efficient
operation of the boiler:
• Ventilation and Siting
When siting the boiler in a confined space it is essential that adequate ventilation be provided. This will ensure that air is
allowed to circulate freely around the appliance keeping down the ambient temperatures.
Refer to Ventilation Requirements (page 6) for further details.
Ensure that the area surrounding the boiler is kept free of items which would impede the good ventilation of the appliance
(eg. towels, linen, etc)
When siting the boiler, take into account the potential requirement for future servicing. Enough space should be provided at
the front of the boiler to enable an engineer to adequately service and/or replace items such as the PCB or heat
exchanger. Space should also be available for the removal of the front casing panel. Please refer to Siting Information
(page 5) for clearance dimensions.
• Power Supply and Wiring
The power supply to the premises must meet the minimum requirements of the unit being installed, with special attention
paid to the supply current, cable size, and RCD recommendation (see page 4 for details).
When fitting external controls, such as a room thermostat or programmer, particular consideration should be given to the
wiring of these secondary items into the appliance. Please refer to the wiring instructions (pages 10 to 17) for full details.
Any breakdown attended to by Trianco which is found to be caused by an incorrectly wired appliance will be chargeable.
It is important that the pump is wired back to the boiler as shown in the wiring diagram as the pump operates
on a switched neutral.
• System
We recommend the placement of isolation valves on both the flow and return pipework of each boiler to be installed.
These are useful as - from time to time - the boiler may require draining of water, and the lengthy drawing-off process can
be avoided by the astute placement of these valves. Please refer to page 8 for further details.
Ensure that any isolation valves are open before first use.
The boiler can be fitted only in an upright position, with the flow connections to the top of the boiler.
