Summary of changes to
original Riello burner
Note the following construction
differences between the general Riello
conversion burner and Riello burner
supplied for use on the Vitola boiler.
N200 and P200 burners for use with
Vitola 200 VB2-18 to VB2-40
The 40-(N,P)200 gas burners when
supplied by Viessmann for VB2-18 and
-22 are constructed with drawer
assembly diaphragm installed in the
combustion head assembly for natural
gas and propane.
Sleeve
Drawer assembly diaphragm
Orifice
The main gas orifice for natural gas is
changed from the 2.0 mm orifice
normally supplied with a 40-(N,P)200
aftermarket conversion burner to that
stated in the table below.
The differences in orifice size for the
VB2-18, -22 cause the manifold
pressure adjustment information in the
Riello 40-(N,P)200 manual to be not
applicable. Use the manifold pressures
in this manual as a starting point for
burner adjustment for the VB2-18, -22.
Do not change orifice, diaphragm or
sleeve-combination. Contact the
Viessmann Technical Department.
