3.3 Mounting of transducer
Attention must be paid to the position and location of the transducer. Fig. 5 shows the required position. Failure to follow
this instruction may result in an inoperable system.
y An Ashcroft XTP-sensor used for sensing draft should be mounted within six (6) feet of the stack probe.
y An Ashcroft XTP-sensor used for sensing room pressure should be mounted within fty (50) feet of the Outdoor
Pressure Probe.

3.4 Installation of stack probe (if applicable)
The probe (page 5) is inserted into the chimney or stack at the point where the draft should be kept constant. This could
be at the appliance outlet, in the vent or similar. Use a 1/4” drill bit to drill a hole in the side of the chimney for the probe.
Acceptable positions are shown below.
Fig. 6
Connect the stack probe to the transducer using the silicone tube. Make sure the tube is connected to the proper trans-
ducer port as show in Fig. 7.
