The maximum volume does not replace the ceiling rule
KOHLER recommends an 8-foot-or-lower ceiling and directs an upgrade to the next generator size for each foot above 8 feet. SteamDesignPro conservatively treats a started partial foot as an upward step and flags it for review because the current documents do not publish a fractional-foot policy.
