Assembly with silencer hood for GZ 3
and GZ 4
When a silencer hood is fitted, the pipe double nipple may have
to be lengthened to a size of 200 mm.
The pipe length between gas ramps and burner
should be as short possible. For gas burners GZ 3 and
GZ 4, the max. pipe length is 800 mm. A bracket is required
to take the weight of the gas ramps.
The dimension H must be checked before erecting boilers with-
out boiler foundations.
