RATINGS FOR WATER
± 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.)
