4.1 InstallatIon - BoIler
Please note following important points before commencing
installation:
InstallatIon & CommIssIonIng
Boilers must be installed, commissioned and serviced by a
competent, qualified engineer, preferably OFTeC registered
and as set out in the installation manual, using correct test
equipment.
WarnIng
The manufacturer cannot accept responsibility for any damage
to persons, animals or property due to error in installation or in
the burner adjustment or due to improper or unreasonable use
or non observance of the technical instruction enclosed with
the burner, or due to the intervention of unqualified personnel.
PosItIonIng tHe BoIler
Compliance guide to part L now states that when installing
a boiler on a new or existing system, the system should be
cleaned, flushed and then protected with a suitable protection
inhibitor
ensure that adequate clearance is available for making the water
and flue connections.
The boiler is serviced from the front and a clearance of 750mm
must be available at the front of the boiler.
No special hearth is required as the boiler is fully insulated, but
the floor must be level and capable of supporting the weight of
the boiler and its water content.
Sound levels must also be a consideration. Whilst Firebird
condensing liquid fuel boilers are one of the quietest boilers on
the market, some householders are particularly sensitive.
a suitable corrosion inhibitor must be added to the heating
system.
underfloor HeatIng
The boiler should not be directly connected to underfloor
heating, as a minimum return temperature of 40˚C is required (it
can be used with underfloor heating with adequate temperature
controls to ensure return values are as stated above).
InHIBItor
Once the initial fill has been completed, ensure adequate
inhibitor is added to protect the boiler and system from
corrosion.
PlastIC PIPIng - WarnIng
The boiler thermostat control and safety system is not designed,
and must not be relied on, to protect plastic pipe from
overheating. Plastic pipe must never be connected directly to
the boiler and there must be at least 1 meter of copper pipe
between the boiler and the first plastic connection. If you choose
to use plastic pipe anywhere on your heating circuits, please
consult the plastic pipe manufacturer for their instructions on
how to ensure their product never overheats. Our boiler control
and safety high limit thermostats are not designed to fulfil this
function. firebird accepts no responsibility for failure of
plastic piping and fittings for whatever reason.
magnetIC fIltratIon
It is recommended at the time of installation of this boiler,
to install a permanent effective magnetic filter on the return
pipework after the last radiator on the central heating system.
This will maintain maximum operational efficiency and protect
the boiler from the damaging, long-term effects of "magnetite"
(black iron sludge). It is essential that the filter is sized similar
to the return pipework e.g. 22mm (¾") or 28mm (1"). In all
circumstances, an effective magnetic filter must be installed in
accordance with the manufacturer's instructions and serviced
annually.
BoIler tHermostat / tHermIstor funCtIon
The control thermostat on the boiler allows the householder to
vary temperature to central heating from a low of 60˚C to a high
of 80˚C, depending on the model. Thermostats have a tolerance
of ±4˚C.
In accordance with eU boiler standards, your boiler is also fitted
with a safety high limit thermostat, fixed at 110˚C. This system
protects the boiler in the event of the control thermostat failing
and keeps the boiler safe.
The safety high limit thermostat will shut the boiler off and will
require the limit button to be pushed to restart the boiler. If this
occurs, you should call your service engineer.
In cases where the flow from the boiler is down to the heating
system, fitting a pump over run thermostat (a pipe stat) is
recommended. This is to prevent the residual heat build up in the
boiler from unnecessarily activating the high limit thermostat
and thus causing nuisance. See Heatpac wiring diagram.
Firebird Kitchen and Heatpac models are factory fitted with an
over run thermostat pump.
tIme and temPerature Controls
The Building Regulations state that central heating systems
must have time and temperature control on the pipe circuits
(eg. thermostatic radiator valves / TRVs, room thermostats,
cylinder thermostats etc.).
Burner
the burner is factory set for use with Kerosene 28 second
Class C2 fuel.
room sealed BalanCed flues
BS 5410-1: 2014 - Code of practice for oil firing. Installations
up to 45kW output capacity for space heating and hot water
supply purposes.
The flue terminal should be mounted so that it is separated from
any combustible material forming a part of the building.
Such combustible material may take the form of cladding on the
surface of a non-combustible wall through which the flue outlet
passes. In such a case, the cladding adjacent to the flue outlet
should be replaced by non-combustible material extending
not less than 50mm beyond the outside dimensions of the flue
outlet.
The wall through which the flue outlet passes may itself be of
combustible material, and if so the flue outlet, where it passes
through the wall, should be surrounded by non-combustible
insulating material not less than 50mm thick. The insulating
material itself should be contained in a steel liner to provide the
necessary structural rigidity and to prevent moisture reaching
the insulating material.
PressurIsed HeatIng system
Firebird recommends that a pressure switch is fitted to all
pressurised heating systems to prevent the burner firing should
the system pressure drop.
If fitted to a pressurised heating system, then adequate
expansion provision must be made to prevent damage to the
heating system and boiler.".
