INTRODUCTlON
The Moduloflame 280 and Moduloflarne~ 420 are low water content floor standing open flue boilers. They are intended for

commercrai appficatrons and are suitablaior both open vented of sealed systems. Each boiler comprises two or three modules,
each module havrng its own water circulating pump, gas valve. burner and heat exchanger assemblies. The modules e&t have
an output of 40 kW and are mounted vertically one above the other providing a high output to floor area ratio. The boilers are of
a lightwerght ~~nstn~ction and so provide a high output to weight ratio. The Moduloflame 280 and 420 models are supplied with
flanged connections to albw for the simple connectron to system pipework or to other Moduloflame boilers of the same sire to
make up banks of boilers and thereby multiples of the output of each boiler. Each boiler has an integral flue duct and is
contained in a pre-assembled case with a single door that can be reversed to enable easy access for installation and
mantenance. Each module can be turned off and serviced independantly and all components are accessible and removeable
from the front. Optional side panels are available as accessories.
