Are there any particular installation requirements for steel components?

No. The usage guidelines for COMAP XPress carbon and stainless steel press-fit systems are the same as for copper press-fit systems.
The COMAP XPress EZ carbon steel system is not recommended for exterior use if it is not housed in polypropylene or without prior application of anti-rust paint.
