Specifications
Aluminum conductors: Do not use aluminum conductors.
Terminals can accept aluminum conductors but the
conductor surface has to be clean and the oxidation
removed and sealed by neutral, acid-free grease before the
conductor is connected.
Additionally, the terminal screw must be retightened after
two days due to the softness of the aluminum. Maintain a
gas tight joint connection to prevent oxidation.
