INSTALLATION OF STACK PROBE FOR PDS 1:
A stack probe is used with Draft Switch. The Draft
Switch monitors the pressure inside the stack and sig -
nals the control to shut down the appliance if insuff-
cient draft exists inside the stack. The probe must be
installed between the appliance and the exhaust fan.
For all installations, the stack probe must be placed
so the flow through the stack is perpendicular to the
tip of the probe. Locate the probe at least the distance
“A” away from any elbows or tees in the stack.
The distance “A” is designed as at least three (3) vent
diameters; A ≥ 3 *V (see figure below). To prevent
condensation from entering the probe or Draft Switch
when installed on a horizontal stack, the probe
must be installed above the centerline of the stack.
For replace installations, the stack probe should be
installed as close to the exhaust fan as possible.
Mechanical Installation
INSTALLATION OF DRAFT SWITCH
The Draft Switch is for indoor installation only. The
Draft Switch
must be installed in a vertical position
with the pressure connection pointing down. Secure
the switch by using the mounting holes as shown on
the gure. After installation connect the tubing from the
probe onto the port marked accessible through the
small of the plastic enclosure. Connect tubing to the
NEGATIVE (-) port on the Draft Switch.
Factory wiring comes with three wires that are already
crimped onto the Draft Switch. The purpose of these
wires is to provide a point in which you can extend the
length of the wire by using wire nuts and additional
wire (not provided).
