10 INSTALLATION REQUIREMENTS
The boiler installation must be in compliance with BS5410 : PART 1 and the Building
Regulations.
10.1 General Requirements
10.1.1 Hearth
The boiler has a hearth temperature of between 50°C and 85°C and should be stood on a rigid,
non-porous, non-combustible base, which is not softened by warmth, to comply with the
Building Regulations.
10.1.2 Service Access
24” (600mm) Clearance should be provided above and in front of the boiler to allow for routine
servicing. Pumped, System and Combi models may require access to the top.
10.1.3 Heating System
The heating system should be installed to HVCA current codes of practice. Before installing the
boiler the new or existing system must be thoroughly flushed to clear all sludge or other foreign
matter such as solder, steel wool and copper filings. The system must be cleansed, neutralised
and protected from corrosion in accordance with BS5449 and BS7593 using suitable cleansing
agent(s) and inhibitor(s) and carried out in accordance with the cleanser / inhibitor
manufacturers‟ instructions. The system must be dosed to the concentrations specified by the
inhibitor manufacturer (refer to the Technical Data section of this manual for the volume of the
boiler when calculating the total system volume). Inhibitor concentrations must be monitored
and maintained on an ongoing basis. Failure of components such as, but not limited to, pumps,
auto air vents, pressure relief valves, plate heat exchangers and non-return valves due to
corrosion product in the system will not be covered by warranty.
10.1.4 Air Vents
The plastic plugs of the auto air vent(s) factory-fitted to the boiler must be loosened when filling
the system in order to bleed the air from the boiler. In addition to any factory fitted air vents it is
recommended that another air vent is fitted at the highest point in the system. Where the flow
pipework drops down from the boiler the installer must ensure that an automatic air vent is fitted
to the top of the pipework to prevent air being trapped in the boiler.
10.1.5 Drain Cock
For all appliances not factory-fitted with drain cocks, one should be fitted to the boiler drain boss
located to the left hand side of the burner. Drain cocks should also be fitted to the lowest points
in the system to allow the system to be completely drained.
10.1.6 Frost Protection
Where there is a risk to the boiler or installation from frost then a suitable frost thermostat
should be fitted. Alternatively the system could be dosed with an anti freeze agent. The Kabin
Pak Combi boiler is factory fitted with a frost thermostat as standard. For all other Kabin Pak
models covered by this manual a Frost Thermostat Kit (Code FSK1) is available as an optional
extra.
10.1.7 Pipework
We strongly advise that all installation pipework is run in copper. However, if plastic pipe is
used, it must be recommended by the pipe manufacturer for use with oil fired appliances and, in
any case, the last 1000mm of pipework connected directly to the appliance must be of copper.
All connections to the appliance must be made with compression fittings.
