4.2
HANDLING THE UNIT
4.2.1
The weight of this appliance exceeds that recommended for a one-man lift. It will therefore be necessary to gain
assistance at times during the removal from its packaging and during installation procedure. Manoeuvring the
boiler may include the use of a sack truck and involve lifting, pushing and pulling.
4.2.2
It should be noted that this appliance may contain sharp edges. Care MUST be taken when handling the appliance
to prevent injury. We advise the engineer to wear suitable P.P.E.
4.2.3
Once the appliance has been fired beware that certain parts will be hot to the touch.
4.2.4
Do not install flues during rain, high winds or in severe weather conditions.
4.2.5
The manufacturers instructions supplied must not be taken as overriding any statutory requirements.
4.3
OPERATING THE APPLIANCE
4.3.1
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless they have supervision or been given instruction
concerning use of the appliance by a person responsible for their safety.
4.3.2
Children should be supervised to ensure they do not play with the appliance.
4.4
ELECTRICAL SUPPLY
4.4.1
Ensure the mains supply voltage, frequency, number of phases and power rating comply with details on
the rating label.
4.4.2
All wiring must be in accordance with the appropriate standards. The equipment must be supplied with a double
pole isolator switch and for new heating systems, and where practical replacement installations, the isolator shall
be situated adjacent to the appliance.
4.4.3
Ensure safety regulations and practices are adhered to when installing and using this appliance.
4.5
GAS SUPPY
4.3.1
It is the responsibility of the Gas Installer to size the gas installation pipework in accordance with BS 6891. Whilst
the principle of the 1:1 gas valve ensures the QuanTec range is able to deliver it’s full output at inlet pressures as
low as 14mb, other gas appliances in the property may not be as tolerant. When operating pressures are found to
be below the minimum meter outlet of 19mb these should be checked to ensure this is adequate for correct and
safe operation.
4.3.2
Allowing for the acceptable pressure loss of 1mb across the installation pipework, it can be assumed that a mini-
mum permitted operating pressure of 18mb will be delivered to the inlet of the appliance. (Reference BS 6400-1
Clause 6.2 Pressure Absorption).
4.3.3
The external gas cock could further reduce the operating pressure when measured at its test point. The pressure
drop is relative to the heat input to the boiler (kW), see Figure 2.
IMPORTANT:
Installation pipes must be fitted in accordance with BS 6891. In IE refer to IS.813.
