* Includes intermittent pilot and

vent damper. Annual Fuel

Utilization Efficiency based on

constant circulation for hot

water models.

±GG models: Add suffix “S” for standard water boiler, “P” for packaged water boiler. Add suffix “E” for intermittent pilot igni-

tion system (available only with 24 volt gas valve). Type of gas: After model number, specify gas by name “Natural” or “Propane”

*Net ratings are based on a piping and pick-up allowance of 1.33 (steam) and 1.15 (hot water). Slant/Fin should be con- sulted before selecting a boiler for installation having unusual piping and pick-up requirements. Ratings must be reduced by 4% at 2,000 feet elevation and an addition al 4% for every additional 1,000 feet elevation over 2,000 feet.

†GXH and GX models: Add suffix “PT” for standard water boiler with tankless heater, “PZ” for steam boiler, “PZT” for packaged steam boiler with tankless heater. Add suffix “E” for intermittent pilot ignition system (available only with 24

volt gas valve). Type of gas: After model number, specify gas by name “Natural” or “Propane”.

** CSA output rating (Btuh).

§ Ratings for GXH-300H are for natural gas only.

‡Tankless heater ratings based on intermittent draw. NOTE: All boilers under 300,000 Btu input are tested and rated for capacity under the U.S. Dept. of Energy (D.O.E.) Test Procedure for boilers.
