Example:
If the site elevation is 2000m
(6682 ft.) then 14 kPa (2 psi) must
be added to the pressure on the data
plate .
If it is necessary to adjust the pressure,
remove the cover on the regulator and
loosen the lock nut, see Figure 6. Turn the
adjusting screw (clockwise to increase pres
-
sure) until the required pressure is obtained.
Tighten the lock nut when finished adjusting.

Air-shutter Adjustment
1)
Record the V
set
.
2)
Open the doors and loosen the adjust
-
ment screw lock-nut Figure 6.
3)
Turn the adjusting screw one turn
counterclockwise.
4)
Close the doors, wait ten minutes then
measure V
set
.
If V
set
is greater than the original value or did not change
(air rich) turn the adjusting screw
another turn counter-clockwise and wait ten minutes. Continue until you observe a decrease
in V
set
then proceed to next paragraph.
If V
set
is less than original value (fuel rich)
refer to Figure 11. Notice that the peak of the
graph is within one quarter of a turn (either
direction) of the adjusting screw. Set the
adjusting screw so that it is one half turn air
rich.
Tighten the lock-nut.
2 .6 .5 Fuel Pressure Adjustment
If the fuel system and burner appear to be
operating correctly, the fuel pressure may be
slightly adjusted to match the TEG’s voltage
with the rated V
set
value. Figure 12 can be
used to determine how much to adjust the fuel
pressure .
EXAMPLE: Rated V
set
= 6.5 V
Measured V
set
= 6.8 V
Difference = -0.3 V
As seen on the graph, the fuel pressure must
be increased 8.5 kPa (1.2 psi).
