relative positions between the RTD sensor
and clip for the left or right-hand boilers.
On the Dometic boiler tube, there are usually
several crimps to hold the inner pump tube.
The best location for the temperature sensor
is above these crimps as shown in Fig 3b -
Sensor Location 1. If it is difficult to mount the
temperature sensor above these crimps,
make sure the tip of the temperature sensor
is in good contact with the boiler tube so that
reliable temperatures are measured by the
temperature sensor (Fig 3b Sensor - Location
2).

Most Norcold boiler tubes are located in front
of the flue tube; exceptions are
Polar 7, 8,
when accessing the boiler assembly is
usually the boiler tube. The location of the
flue tube determines the RTD clip alignment
in step 5. Generally the Norcold clip would be
to the right as seen in Fig. 4a.
