Notes for Model 94 Boilers
1. Ratings: Net I=B=R water ratings are based on piping and pick-up allowance of 1.15. Net I=B=R steam ratings are based on
the following piping and pickup allowance of 1.288.
2. Gas pressures based on minimum pressure required to inlet of gas train under full-flow conditions.
3. All boiler-burner units to be force draft fired. Vent termination need not exceed the height of the roof by more than 3 feet.
4. Burners for “H” boilers must be capable of firing the boiler at rated input and specified overfire pressure without flame
impingement. Any burner modifications and/or adjustments in the field to obtain proper operation are the responsibility of the
installing contractor and/or start-up engineer.
5. “H” boiler burner mounting plates will have the following permanent tag: “The operation of the burner mounted to this boiler
