Contents FoReWoRD We would like to thank you for purchasing a high efficiency Firebird condensing liquid fuel boiler with an Elco low NOx burner. This instruction manual is produced for the reference and guidance of qualified installation engineers, preferably OFTEC (Oil Firing Technical Association) registered. EU legislation governs the manufacture, operation and efficiency of all domestic central heating oil boilers.
saFety safety - conformity was demonstrated by meeting the HealtH & saFety inFoRMation following standards: The installer should be aware of his/her responsibilities under the current, local Health and Safety at Work Act. The BS EN 60335-1: 2012 + A2: 2019: Household and Similar interests of safety are best served if the boiler is installed Electrical Appliances - Safety - Part 1: general Requirements and commissioned by a competent, qualified engineer,...
stanDaRDs & Regulations to ensure the highest standards of installation & safety, it Regional water supply (water fittings) regulations/ is important that the boiler is installed and commissioned byelaws. by a competent, qualified engineer, preferably oFteC trained and registered. it is the responsibility of the Regional control of pollution (oil storage) regulations.
2.1 stanDaRDs & Regulations - ConDensate DisPosal Firebird condensing boilers, when in condensing mode, extract more heat from the flue products and the resulting condensate which is mildly acidic, needs to be drained from the boiler via a condensate pipe to the drainage system.

Care should be taken to locate it so as to prevent either the end user or their neighbours perceiving the plume to be a nuisance. It should be noted that the normal statutory clearances required around low level flue terminals may not be sufficient to cope with plume dispersal from a condensing boiler.
For concentric balanced flue: of installation (this can also be done online on the - the cone supplied should be inserted in to the end Firebird website). a copy should be retained by the of the flue; commissioning engineer.
BuRneR annual servicing must be carried out by a competent, qualified engineer, preferably oFteC registered and familiar with Firebird products. Please refer to the burner manual for specification and combustion check information. Do not commence service until both the electrical and fuel supply to the boiler have been safely isolated.
