The captured official documents do not print an efficiency column for both sizes, so the comparison rests on capacity and the printed mechanical data. The ClearFire-V 60 HP is rated 2,070 lb/hr steam from and at 212°F against the ClearFire-V 50 HP's 1,725 lb/hr. The 50 HP and 60 HP are the largest CFV sizes: both use a 3 in steam outlet, 1-1/4 in feedwater, 1-1/2 in gas, a 10 in stack, 8 in combustion air and a 1,200 W blower, with the 60 HP adding 345 lb/hr of steam capacity.
Water and pressure data are printed in the family document. Pressure rating: 150 psig design; 60 psig minimum operating on the smaller unit against 150 psig design; 60 psig minimum operating on the larger.
Both models are documented in the same official Cleaver-Brooks material, so the choice is a load and plant-layout decision: size to the calculated demand, then verify connections, venting and weight in the family document for the exact model.
