Table C altitude and ambient heat rejection factor adjustment for HT and LT circuits
LT & HT circuit heat rejection calculation procedure
1. Determine derate multiplier vs. temp derate from table A.
2. Using the multiplier from #1 above as the percent load factor, determine the heat rejection.
3. From table C find the HT and LT circuit multiplier.
4. Multiply the result of step 2 by the result of step 3 to obtain the heat rejection at your altitude and temperature.

Notes:
1. Ambient temperature is the same as air filter inlet temperature. LT inlet temperature is 40 °C, or 10 °C above ambient,
whichever is higher.
2. Table refers to the capability to run at continuous power level. For short periods of time the genset can run at 5 °C higher
temperature with reduced efficiency.
3. Subtract 3 °C ambient temperature capability for each 100 mm (4 in.) H
2

page 3.
4. This generator set is capable of operating for short periods of time under with the LT temperature and/or the fuel methane
number outside of the recommended limits with decreased performance. Operation in the green area will result in normal
performance. Operation in the yellow area is recommended only for short periods of time and will result in reduced efficiency
and shorter spark plug life. Operation in the red area is NOT recommended.

Continuous rating definition
Applicable for supplying power continuously to a constant load up to the full output rating for unlimited hours. No
sustained overload capability is available for this rating. Consult authorized distributor for rating (equivalent to
continuous power in accordance with ISO8528, ISO3046, AS2789, DIN6271, and BS5514). This rating is not
applicable to all generator set models.
