Draught Regulator - Honeywell Braukmann Fr 124 - Assembly Instructions - Atmos C15E Instruction Manual

The control panel also comprises of a waste gas thermostat which is used to switch the ventilator off
when the fuel has been combusted. When igniting, position to the "firing-up" position (minimum
value). When the fuel has sufficiently flared up, set it to the operating position in which the ventilator
runs until the fuel has completely burnt out. It is necessary to seek and discover an optimal position
of the thermostat; which depends on type of fuel, chimney draught and other conditions. The outgoing
water temperature should be monitored on the thermometer /18/ situated on the control panel. There
is also an irreversible safety thermostat on the panel. Wood supply gasification boiler DC50SE is not
equipped with Honeywell draught regulator FR 124 and typical regulation valve (aperture for FR 124
on the water outlet from the boiler must be blinded). It is equipped with regulation valve with a servo-
drive and spring placed in the combustion air inlet. This valve is controlled with regulation and waste
gas thermostat in accordance with outlet water temperature; like the draught ventilator. When the
thermostat is switched off, it switches off automatically. Regulation valve is set by the manufacturer
to a maximum opening of 30 mm. Maximum valve opening can be altered as necessary. This can
change the boiler output and its combustion. Boiler DC15E is not equipped with a ventilator, regula-
tion, waste gas and safety thermostat. Output regulation is carried out only with Honeywell FR 124
draught regulator, which controls the regulation air valve. Panel on DC15E type is equipped with a
switch and thermostat for a pump.

FR 124 – Assembly instructions
Disassemble the lever /1/ and coupler /2/ and screw the regula-
tor into the boiler.
Setting
Heat the boiler to approx. 80°C. Set the setting handle to the
temperature read on the boiler thermometer. Tension the air flap
valve chain in a way that provides the required boiler output;
the gap at the air (control) flap valve may range between 3 – 50
mm. The valve minimum gap is set by a setscrew to 3 – 8 mm;
boiler service-life prolonging feature, do not decrease. Other-
wise, the boiler and ventilator may get covered in tar and their
service life would be reduced. In cases where there are insuf-
ficient general draught conditions, slightly increase the permis-
sible minimum gap.
Draught regulator functional check
Set the setting handle to the required temperature of water exit-
ing the boiler (80 - 90 °C). When the water temperature reach-
es its maximum of 95°C, the control flap valve must be fully
closed (only providing the setscrew gap). It is always necessary
to fine-tune the specified operating temperature (80-90°C) uti-
lising the mixing valves behind the boiler either manually or by
electronic regulation with electric actuator.
