Gas boilers hardly ever make hot water inside them and residential boilers are rare today that have to be kept up in temperature to keep them from weeping between sections (your GV4 has elastomeric (rubber-like) seals between sections, so they move while keeping sealed), so they are almost all (comparatively) cold start. You wired your system for cold start, which is fine.
