7.6.3 Installation of Temperature Sensor and
Burner Cables
NOTICE
When installing a Logamatic control, you
must replace the installed brass well with
the chrome well supplied with the Logam-
atic control.
Remove factory installed sensor well.
Apply sealant to Logamatic well and screw into tap-
ping.
Remove plug.
SYSTEM DAMAGE
Be careful not to kink or have the capillary
tubes come in contact with sharp surfaces.
CAUTION!
Route the capillary tubing carefully and
avoid kinking. Route capillaries and
sensor wiring to the immersion well.
Strap excess tubing and wiring together and place on
top of insulation.
Plug the burner cable into the designated location of
the Logamatic control (Fig. 63, page 68).
Burner wiring can be routed down towards the front
of the boiler. If burner is supplied with a wiring har-
ness, route harness between jacket panels and boil-
er insulation.
Connect end of burner cable into green plug to Log-
amatic control panel.
Bring the sensor bundle to the installed chrome well
and slide bundle into the well. The plastic holding clip
will slide back.
Insert all sensing elements fully into the well and se-
cure tubing with furnished metal holding clip.
NOTICE
Ensure all sensing elements are all fully in-
serted into the well and make good contact
with well inner surface. Use the tension
clip in the middle of sensing elements.
