The 'universal' adapter style is designed for units that don't have a replaceable sliding vent door like the Kamados do.
Both variants of the Universal Adaptor are 70mm / 2.8" long and have a female coupler to insert the Smartfire Controller into on one end, and the the other end has a male 1" BSP pipe male thread to make it easy to screw tight some lock nuts on either side of a pit wall or connect into other ball valve adaptors.
The 'Dual Thread' variant also features a female 3/4" BSP thread on the inside of the pipe end that has the 1" BSP on the outside. This provides two methods to connect the adaptor to your pit. This is ideally suited for Weber/WSM/ProQ folk who instead of drilling a 35mm hole want to connect through the bottom air inlet daisy wheels. It's a little more expensive as the more complicated design has to be machined from solid stainless steel pipe!
Universal Adaptor (Standard) is Designed For:
- Offsets, such as Radar Hill Smokers.
- Custom smokers that may be using a BSP ball valve (BYO 2" to 1" adapter as required).
- Weber kettles.
- Dual Thread Universal Adaptor is Designed For bullet style smokers with daisy wheel air inlet(s) near the charcoal basket, ie:
- ProQ Smokers, such as the Elite series.
- Weber Smoky Mountains.
- To use it, you simply insert the Smartfire Controller into the precisely machined female adapter end - which is of the same dimensions as other draft control units.
- If you're drilling a hole, use of this adapter this does require careful location of a ~35mm drill hole that won't disturb ash but isn't too close to the main fire.
- Daisy Wheel installation requires use of a round file to increase one of the daisy wheel holes to ~20mm. You'll also need to block the other three unused holes, the recommendation is cut small tear drop sized pieces of tin and insert between the daisy wheel and the BBQ wall. Purchase a 15mm to 3/4" BSP male plumbing adaptor and 15mm lock nut. Insert the 15mm end through the daisy wheel and attach the lock nut on the internal side. Attach the Dual Thread Universal Adaptor to the 20mm / 3/4" BSP.
