V
set
Vs Set up Power
If less than rated power is desired:
5)
Determine the desired power output.
6)
Determine the corresponding set up power by adding 0.3 watts to the desired power for
each ºC difference between the present and maximum ambient temperatures.
7)
Refer to Figure 12 to determine the related V
set
and record as Item 6.
2 .8 Fuel & Air Adjustment
After the TEG has been operating for one hour, V
set
should not be changing with time. The
readings on the start up data sheet at 40 and 60 minutes should not differ by more than 0.2
volts. When you are satisfied that V
set
is not changing with time, compare the measured value
of V
set
with the required V
set
, Item 6. Proceed with air shutter adjustments to optimize the burn-
er first (section 2.9) then adjust the fuel pressure as required (section 2.10).
