Normal operating range
This unit is tested in accordance to UL 2200 standards with an operating temperature of -20 °F (-29 °C)
to 122 °F (50 °C). For areas where temperatures fall below 32 °F (0 °C), a cold weather kit is
recommended. When operated above 77 °F (25 °C), there may be a decrease in engine power. See
Engine.
These generators are rated in accordance with UL 2200, Safety Standard for Stationary Engine Generator Assemblies, and CSA-
C22.2 No. 100-04 Standard for Motors and Generators.
* NG ratings will depend on specific fuel joules/BTU content. Typical derates are between 10-20% off the LP gas rating.

Engine power is subject to and limited by such factors as fuel BTU/joules, ambient temperature, and altitude. Engine power
decreases approximately 3.5% for each 1,000 ft (304.8 m) above sea level, and also will decrease approximately 1% for each 10 °F
(6 °C) above 60 °F (15 °C) ambient temperature.
