Flue adapters
The Tofino i40 uses 3” flex tubing for the air intake and 4” flex tubing for the air exhaust. The Tofino i40 ships
with a flue adapter which fits onto the top of the firebox and is affixed with a connection bolt (Figure 11).
Depending on the amount of room available for the installation of the Tofino, the installer may want to remove
the flue adapter and attach it to the flex tubes which will have previously been inserted down the chimney.
The installer must make sure that the air intake vent and air exhaust vents attach to the correct ports on
both the flue adapter and the vent terminal. The vent terminal and the flue adapter are marked with an “I” (air
intake) and “E” (air exhaust).
