EXTENDED HEAD KIT
“Standard head” burners can be transformed into “extended
head” versions, by using the special kit. The kits available for the
various burners, giving the original and the extended lengths, are
listed below.
DEGASSING UNIT
It may occur that a certain amount of air is contained in the fuel
sucked up by the pump.
This air may originate from the fuel itself as a consequence of de-
pressurisation or air leaking past imperfect seals.
In double-pipe systems, the air returns to the tank from the return
pipe; in single-pipe systems, the air remains in circulation causing
pressure variations in the pump and burner malfunctions.
For this reason, we advise installing a degassing unit near the
burner in single-pipe installations.
Degassing units are provided in two versions:
CONNECTION FLANGE KIT
A kit is available for use where the burner opening on the boiler
is of excessive diameter.
SOUND PROOFING BOX
If noise emission needs reducing even further, sound-proofing
boxes is available.
LPG KIT
For burning LPG gas, a dedicated kit is available with RLS dual
fuel burners.
GAS MAX PRESSURE SWITCH KIT
If necessary a gas max pressure switch kit is available.
GAS TRAINS APPROVED ACCORDING TO EN 676
Refer to the instruction manual.
