FireBird Enviromax Popular C20 Technical Manual page 4

FOREWORD
We would like to thank you for purchasing a high
efficiency Firebird C Range Condensing domestic
central heating oil fired boiler. This instruction
manual is produced for the reference and
guidance of qualified installation engineers such as
those who are OFTEC registered. EU legislation
governs the manufacture,
efficiency of all domestic central heating oil
boilers. Our boilers and burners will are supplied
as matched units tested and approved to OFTEC
Standard OFS Al00.
FIREBIRD Boilers are full manufacturing members
of OFTEC (Oil Firing Technical Association) and
are participating in its Boiler testing and approvals
programme to comply with OFS A100 and EC
Efficiency Directive.
You should ensure that all installation, servicing
and commissioning works are carried out by a
competent person, such as one registered by
OFTEC. It should be noted that it is the
responsibility of the Installer/Householder to
ensure that the
commissioned. Failure to do so may invalidate
the boiler guarantee and any extended
warranty.
SERVICING
The boiler requires servicing on an annual basis
to ensure it maintains its efficiency, continues
to perform reliably and as a regular check on
its built-in safety features. It is important that
servicing should be conducted by a competent
engineer, such as one who is OFTEC trained
and registered.
All appropriate OFTEC manuals and BS
Standards should be studied and their
requirements adhered to and used in
conjunction with these instructions. This
manual includes a list of some BS Standards
and Building Regulations.
OFTEC is conducting training and registration of
engineers and this is to be commended, as
reading of this manual alone for installation and
servicing procedures cannot replace the critical
advantage provided by training and years of
experience.

INTRODUCTION
Firebird domestic oil fired condensing boilers are
highly efficient and are all independently certified
to Sedbuk Band A. They use less fuel and have
lower running costs than non-condensing boilers.
Because of their increased efficiency they emit
less carbon dioxide than non-condensing boilers,
which will contribute to efforts to reduce global
warming. The incredible efficiency of the Firebird
C Range Condensing Boiler is due to the
development of a single boiler unit with three
unique heat exchanger units. This gives a
exchange surface greater than non-condensing
boilers.
This additional surface area increases the amount
of heat extracted from the combustion process
and thus reduces the heat wasted to atmosphere.
So much heat is extracted from the combustion
gases that their water vapour element condenses
into liquid form, releasing the latent heat that was
used to create the vapour in the first place. It is
this heat gain that gives the condensing boiler its
significant advantage over a non-condensing
model. In order to enable this high level of heat
extraction to take place, the water in the boiler's
heat exchanger must be cooled down to about
55˚C or less, this means that the boiler is
working at its maximum efficiency.
The condensate produced is often mistakenly
considered to be highly acidic. In fact the acidity of
condensate from a Firebird C Range Condensing
Boiler will be found to be as low, if not lower, than
that of vinegar.
A 20˚C. differential between flow and return
should be maintained to achieve maximum
performance from the Firebird C Range
Condensing Boiler.
The Firebird C Range Condensing Boiler is
suitable for underfloor heating provided the
return temperature is above 40˚C. at all times.
The Firebird C Range Condensing Boiler even
when not working in condensing mode will still
operate at extremely high efficiencies making it
suitable for fitting to an existing heating system
without alteration to the radiator sizes.
The burner is factory set for use with
kerosene 28 second class C fuel.
