Continue to screw the adjusting knob (23) clockwise into
the valve spindle (20) until the holes for the spring pin
(17) are clear. Install the spring pin. Be sure that it sits evenly in
the hole. Back the adjusting knob out counter clockwise to apply

While depressing the lever (21), insert the valve spindle (20)
through the venturi lever (16) and into the case (10). Be sure
the valve spindle engages the two index flats molded into the case.
Gently release the lever.
CAUTION:
Do not allow the lever to spring up forcefully as
it passes through the case. This could cause the lever to
disengage from the shuttle valve, requiring disassembly of
the valve spindle assembly.

Slide the o-ring (3)
down the threaded
end of the valve spindle (20).
Screw the heat exchanger (2)
clockwise with the hexagon
facing outward, onto the valve
spindle until hand tight. Using

crow-foot, tighten the heat
exchanger to a torque of 26.5
in-lbs (3 Nm).
CAUTION:
Ensure that the lever is vertical after tightening.
CAUTION:
Excessive tightening of the heat exchanger will
damage the two flats inside the case.
