Cleaver-Brooks CBEX (firetube)
The CBEX is Cleaver-Brooks' flagship integrated firetube (boiler, burner and controls in one 'EX technology' package) — listed in the condensing-hydronic catalogue but largely a steam-plant line with hydronic variants, so Boilers.ca records it as firetube context.

About the CBEX (firetube)
Cleaver-Brooks positions the CBEX as its flagship integrated firetube boiler: boiler, burner and controls engineered together under 'EX technology', with emissions copy of under 5 ppm NOx / under 10 ppm CO without SCR, renewable-fuel capability and a 3-pass option with pre-piped economizer.
Although the CBEX appears in Cleaver-Brooks' condensing-hydronic catalogue listing, it is primarily a steam-plant line (hydronic variants exist), so Boilers.ca keeps it as a firetube context hub rather than a condensing-hydronic recommendation.
