Assembly of the gas train
The gas train is type-approved according to standard EN 676
and is supplied separately from the burner.
The gas train can enter the burner from the right or left
side, depending on which is the most convenient, see
Fig. 18.
The gas train must be connected to the gas attachment
1)(Fig. 18) with the flange 2), the gasket 3) and the screws
4) supplied with the burner.
The gas solenoids must be as close as possible to the
burner, to ensure that the gas reaches the combustion
head within the safety time of 3 s.
Ensure that the maximum pressure necessary for the
burner is included in the calibration field of the pressure
adjuster.
When fitting the burner on the two guides, it is
advisable to gently draw out the high voltage cable
and flame detection probe cable until they are
slightly taut.
