Setting Up the Weber Vents to Cook
Low and Slow
The approach to smoking “low and slow” requires setting
up the draft restriction on the Weber kettle. As you know the We-
ber has two controllable vents – a lower and an upper vent.
Shown below is a photograph of the lower vent system. Take a
common pencil, place it in the slot where the arrows are in the
photograph, and slide the vane or spoke against the pencil, the re-
sult is about a 3/8” gap in each lower vent, which isthe mini-
mum setting!We currently use the lower vent fully open and
have no problem regulating temperature. The lower vent gap can
be varied to compensate for a leaky kettle. You can calibrate the
vanes on the Weber Gold’s ash catcher and can regulate tempera-
ture via the lower vent. On the less expensive Weber Silver
model it’s difficult to set the vents with any precision. Regardless
of model, we use the upper vent to control temperature in the ket-
tle. It is the most reliablewhen running dry the lower is set very
narrow.
