Wiring Preparation - Thermador HPCN36WS Instructions

Calculating the optional chimney extension height
Optional chimney extensions are available for purchase in
6'' (153 mm) and 18'' – 35'' (457 – 889 mm) sizes to cover
the space between the top of the hood and ceiling.
1. Measure height from floor to ceiling (A, figure).
2. Measure height from floor to cooking surface (B,
figure).
3. Measure hood mounting height from the bottom of
hood to cooking surface (C, figure). Dimension must
be a minimum 30'' (762 mm).
4. Calculate optional duct cover height (D, figure):
D = A – (B + C + 18'').

*Follow cooking appliance manufacturer's recommendations.
NOTICE: The hood could incur some damage from heat if
a Thermador Professional series range or rangetop is
operated with multiple burners at high settings under a
hood that is installed at minimum clearances while the
hood is turned off.

Wiring preparation

IMPORTANT: Cutting off a connector to the appliance,
blower, or to the extension cable kit will void the warranty.
Ensure wiring does not interfere with optional chimney
duct cover (where the cover touches the wall).

Prepare the wire hole cutout in the ceiling with a 5/8''
(16 mm) diameter clearance hole for a ½'' (12.7 mm)
conduit to the junction box.
