STANDBY RATING: Standby ratings apply to installations served by a reliable utility source. The standby rating is applicable to varying loads for the duration of a power outage. There
is no overload capability for this rating. Ratings are in accordance with ISO-3046-1. Design and specifications are subject to change without notice.
Note: Fuel pipe must be sized for full load.
For Btu content, multiply ft

/hr x 1000 (NG)
For megajoule content, multiple m³/hr x 93.89 (LP) or m³/hr x 37.26 (NG)
Refer to "Emissions Data Sheets" for maximum fuel flow for EPA and SCAQMD permitting purposes.
