concentration in the flue gases, their temperatures and the average
temperature of the water in the boiler.
To suit the required appliance output, fit the nozzle then adjust the pump pressure, the setting of the
combustion head and the air damper opening in accordance with the following schedule.
NOZZLES RECOMMENDED :
Monarch type R
Delavan
type W
(till 0,65 GPH)
Delavan
type B
(from 0,65 GPH)
Steinen
type Q
Danfoss type S
Satronic type S
Fluidics
type SF
PRESSURE:
12 bar :
The pump leaves the factory set at this value.
COMBUSTION HEAD SETTING
: This is done when fitting the nozzle, with the blast tube
