Notes to be Aware of:

  • Be sure that in extra wide grills your motor is not sitting too close to the grill. Due to the added weight of this drum, the rubber coupler can shear off once subjected to excessive heat where it can become soft. The solution for this is to choose the extra long 50" rotisserie rod above and to place the motor further away from the grill. Additionally refer to this LINK (Figures 126-155) to see how you can create a heat shield to protect the motor.
