It should also be understood that twisting the blade 180 in the slots 185 in one direction, e.g., the right, will lock the blade into the +14° pitch position, which is appropriate for warm or hot weather operation since the fan would circulate air downwards. Conversely, locking the blade into the -14° pitch position would be better for cool weather operation since the fan would lift cool air and move the heated, stratified air at the top of the canopy 100 (with the vents 105 A preferably closed) downward.
