3.4.11 Boiler Control Panel Connections
Make sure the control panel is secured properly on the front of the boiler
(Section 3.3.5)
.
Install the 2 sensors bulbs from the control panel in well # 27
(Shown in Section 6.1).
Sensor bulbs
need to be pushed all the way to the bottom of well. Capillary tubes should be bent carefully over lip
of well and clipped into place
(Section 3.3.5)
.. Verify that the thin sensor for the Lo-Limit thermostat
is installed in the dry well located on the blower box
(Section 3.3.5)
. Set the Lo-Limit thermostat to
90 °C (194 ºF)
(Section 4.1)
.
3.4.12 Description of Functions
Note in brackets
(Section 4.1).
To start the boiler from cold, the reset switch
(N)
must be pressed, after which a relay closes and re-
mains active. The relay switches the fan and circulator on. When the boiler temperature reaches the
minimum thermostat setting
(P).
Boiler thermostat (I) regulates the boiler. If the boiler temperature
falls below minimum thermostat setting
(P),
the fan and the circulator pump is switched off.
3.4.13 Operating Thermostat
The operating thermostat regulates the fan and must be set high, possibly at max. There is a stop screw
behind the thermostat knob corresponding to the setting for a minimum operating temperature of about
85°C (185 ºF). The stop for the knob must be on the left side of the stop screw so that the boiler tem-
perature is kept above 80°C (176 ºF)
(see Section 4.1).
3.4.14 Lo-Limit Thermostat
There is a Lo-Limit thermostat B15 on the boiler control panel which switches off the fan and the cir-
culation pump M7 if the wood has burned out. Set the dial to 90°C (194 ºF), the thin sensor must be
placed in the flue gas collection box (Blower box) immersion tube. This ensures that the fan is
switched off relatively quickly after the boiler has run out of fuel
(see Section 4.1).
3.4.15 Circulator Pump
The boiler control panel controls the circulator pump M7. The pump must be connected to M7. Pump
M2 is not used and has no thermostatic function. Circulator pump M7 is regulated by the Lo-Limit
thermostat
(see Section 4.1).
3.5 Commissioning the Boiler
