Refrigerator Service Manual
Flue
The
fl
ue on all NX6X / NX8X, NXA6X / NXA8X terminates a
few inches above the canister. See Fig. 24. The
fl
ue comes
equipped with a removable baf
fl
e ("spiral baf
fl

heat de
fl
ector.
The
fl
ue and its components should be checked annually. In
roof exhaust venting applications, the refrigerator must be
removed from the enclosure to check or service the
fl
ue or any
of its components.
In most sidewall exhaust venting applications, removal of the
side wall exhaust vent provides clear access to service the
fl
ue
or any of its components.
A one inch diameter, loop-handle, twisted wire brush with a 27
inch wire handle is recommended for sweeping clean the
fl
ue.
Heat Defl ector
The heat de
fl
ector, de
fl
ects hot exhaust gases to the sides.
See Fig. 24. It also keeps dirt and debris from getting into the
fl
ue. Cooling performance may be affected if the heat de
fl
ector
is not installed or is not installed correctly.
Spiral Baffl e
The spiral baf
fl
e, traps and transfers heat to the cooling unit
generator. See Fig. 24.
A retaining wire suspends the spiral baf
fl
e in the
fl
ue just
above the
fl
ame. See Fig. 25. The spiral baf
fl
e should be
checked annually. To remove the spiral baf
fl
e from the
fl
ue:
1. Remove the heat de
fl
ector.
2. Unclip the baf
fl
e retaining wire from the rim of the
fl
ue.
3. Pull the baf
fl
e out of the
fl
ue tube.
