4.4.1 Concrete Work - Overview
Important
The weight of grain in a full NECO dryer will range from 16 tons to more than 200 tons.
•
Support the frame of the dryer with properly designed and sized footings.
•
NECO recommends having a concrete pad under the dryer to allow for easy clean-up.
•
The dryer must be anchored and secured against wind loading. Consult a civil engineer who has
experience with soil AND wind conditions in your area.
•
Work with your millwright or installer, and consult NECO if additional information is needed.
4.4.2 Set Up Fuel Supply
Hire a professional to plan, setup, and connect the chosen fuel supply: liquid propane or
natural gas. Either type MUST include an emergency shut-off valve.
For Dryer Installations in Canada
The equipment shall be installed in accordance with the Natural Gas and Propane Installation Code, CSA B149.1
and the Propane Storage and Handling Code, CSA B149.2, or applicable provincial regulations, which should be
carefully followed in all cases. Authorities having jurisdiction should be consulted before installations are made.
Propane (LP) Fuel Source
Contact your gas supplier regarding the location of fuel tanks and the safe storage, transport and handling of
fuel. The LP storage tank must be located at least 25 ft (8 meters) from any structures. Local codes may require
more distance.
When propane is the fuel source the tank, use a
vapor tap
and a
liquid tap
. Equip the liquid tap with a rapid
flow shutoff valve. This valve will stop the flow of propane if a fuel line breaks.
Prevent oil sediment from entering the fuel system by propping one end of the propane tank higher than the
other end, as shown in
.
