Refrigerator Service ManualN6XX/N8XX Models
Flue
The flue on all N6XX/N8XX terminates a few inches
above the canister. See Figure 14. The flue comes
equipped with a removable baffle ("spiral baffle") and a
metal heat deflector.
The flue 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 flue or any of its components.
In most sidewall exhaust venting applications, removal
of the side wall exhaust vent provides clear access to
service the flue 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 flue.
Heat Deflector
The heat deflector, see Figure 14, deflects hot exhaust
gases to the sides. It also keeps dirt and debris from
getting into the flue. Cooling performance may be
affected if the heat deflector is not installed or is not
installed correctly.
Spiral Baffle
The spiral baffle, see Figure 14, traps and transfers
heat to the cooling unit generator.
A retaining wire suspends the spiral baffle in the flue
just above the flame. See Figure 15. The spiral baffle
should be checked annually. To remove the spiral
baffle from the flue:
1. Remove the heat deflector.
2. Unclip the baffle retaining wire from the rim of the
flue.
3. Pull the baffle out of the flue tube.
Flame Appearance
The flame should be light blue with sharp blue root
cones and a steady burning flame plume. See Figure
16.
A flame that is mostly orange or yellow, is erratic, and
unstable, indicates a "dirty" burner. Burner cleaning
procedures appear on page 30.
!
CAUTION:
Do not cut or modify the spiral baffle retaining
wire! The wire positions the baffle for optimal heat
transfer.
