6. Install the remaining smoke stack and the steam stacks (if you have hoods). Then install
the collars around the stacks, above the roof jacks.
7. Install the Chinese hats or/and the rope operated stack covers. In the case of the stack
covers, make sure the dominant winds will close them.
8. The last step is to install the steel wires holding the stack in place. Make sure not to tighten
too much. The chimney will expand significantly with the heat.
INSTRUCTIONS
Only use dry wood, without paint or other chemicals (no treated wood). Never use any products
made of plastic, tires, coal or any other combustible material. The use of any unauthorized
combustible will void the warranty.
To optimize combustion, the best length for the wood used in the Venturi evaporator is 20”. The
grates inside the burning chamber are 20” long. So with 20” logs, we get the maximum benefit
of the air drawn in the burning chamber.
The quality of the wood that will be burned is an important factor in the performance of the
evaporator. Poor quality wood will reduce the boiling rate, you will fill the burning chamber
more frequently and the maple syrup produced will be darker. See table 1 to find the heat
potential for each type of wood.
