DRAFT INDUCER INSTALLATION
SINGLE UNIT
In single unit applications the oven must be
mounted to its cart before completing these
steps.
DOUBLE UNITS
When installing the draft inducer in a stacked
application, it must be completed only after
the previous "Stacking Instructions" have been
performed.
1. Install the bracket that came with the draft
inducer with three (3) of the #10 sheet metal
screws provided.
2. Make certain the knockout is
removed from the unit, top unit ONLY
in stacked situations. see illustration
shown here.
3. Place the draft inducer, without the
louvered cover, on top of the unit,
over the exhaust collector.
4. Slide the inducer forward until
secured under the attached bracket.
Using six (6) #10 sheet metal screws,
fasten this assembly onto the top of
the oven.
5. Connect the 9 pin and two single
electrical connections from the
draft inducer to the wiring harness
protuding from the top of the unit.
NOTE: There is no polarity
distinction between the single
connections.
6. Test the Inducer by plugging in the
120V connection to the oven (upper
oven on stacked assemblies) and
make sure the axial fan(s) on the draft inducer are turning. The fans will turn without the
controls being on.
7. Fasten the draft inducer cover to the top of the oven with the #10 sheet metal screws
provided.
IMPORTANT: IMPROPER DRAFT INDUCER INSTALLATION WILL ADVERSLY
AFFECT THE PERFORMANCE OF YOUR LANG EQUIPMENT.
EARTHQUAKE STRAPS
If the oven is to be installed with casters, it must be secured to the building structure. To do
this, attach an oven earthquake strap (not supplied) to the eye bolt (supplied) at the bottom
right corner of the oven. For stacked ovens, attach the strap to the eye bolt of the uppermost
oven. Connect the earthquake strap to the wall or other structure per instructions supplied
with the strap.
