Install your dryer exhaust vent as short as possible
Install your dryer exhaust vent as straight as possible
Use as FEW elbows as possible in the dryer exhaust vent routing
Terminate the dryer exhaust vent on a side wall or low side wall ( easy access/avoid roof terminations)
Use four inch (4") rigid round smooth interior metal pipe with a minimum 26 gauge.
Connect all of the vent joints with a heavy duty all weather metal tape/and/or metal clamps. Face the male end of the vent pipe towards the termination.
Do not use any sheet metal screws at connection points or create any protrusions in the vent
Always use a recessed dryer box at the rear of the dryer appliance to minimize any chance of the connector hose (transition hose) kinking or crushing to the rear of the appliance
If possible, ensure that there is easy access to the connector hose ( transition hose), consider a high side wall or ceiling mount connection from the dryer appliance to the dryer wall port.
