© Oroflam s.r.l. 2011 Burner type WPB 30C is a pellet burner, with forced burning air, horizontal flame,  five-steps power modulating.  This burner must be installed in boilers with vacuum-  operating combustion chamber (with at least 0,25 mbar draught) and that are  arranged to work with a flame power suitable for the burner heating power. The  burner flame modulation follows the temperature change of the heating system  outlet water using a temperature feeler, part of the burner’s equipment.  The burner can be installed to work in combustion chambers of owens, little  furnaces, hot air generators, etc. expressely designed to be coupled with it. The  optimum combustion chamber dimensions are: 380 mm width, 460 mm height, 630  mm length; the suitable combustion chamber dimensions range are: 300 ÷ 500 mm  width, 460 ÷ 500 mm height, 410 ÷ 650 mm length, equal to a 68 ÷ 110 dm3 volume  range.  The burner may be installed also in a normal cast-iron boiler or in a boiler with a  little back-pressure in the combustion chamber: please see the back-pressure  graph on the left. This particular way of installation will need a working parameters  modification of the burner by the installer and will also need a boiler modification  adding an access door to the combustion chamber and placing inside it a tray for  the ash extraction. An inspection by an authorised technician will need to know if a  solution like this may be possible and cheap.
