The status light illuminates briefly, then blinks. The burner should ignite as
soon as pressure is restored. Press and to extinguish the status light.
Gyr machines The status light should illuminate momentarily, but this may be too
quick to see. The flame control automatically resets and attempts to ignite the burner.
5.10. Step 9: Minimum burner box air pressure

Fireye machines Select SETUP MODE E (see Section 4.1 , page 6 ). This sets the modulating
gas valve to 000 and displays the inlet temperature.
Gyr machines Set the modulating gas valve to position 000 (MVP=000). See Section
4.2 , page 7 .
1. Look at Figure 2, page 5 . Attach one side of the manometer to GAB (the lower pressure) and
leave the other side open to the atmosphere.
2. Remove the cover from SPBB . Carefully turn the center adjustment screw (white potentiome-
ter that the arrow points to) counterclockwise until the top of the screw is level with the collar.
Do not allow the adjustment screw to come out of the switch. The screw is spring loaded.
3. Adjust VB until the manometer shows the value specified in Section 2 , page 2 .
4. Look at the burner box pressure light ( ) on the status light panel. Slowly turn the adjust-
ment screw on
SPBB
clockwise until the status light illuminates and the burner extinguishes.
5. Close VB fully.
5.11. Step 10: Maximum back (air) pressure

The dial on
SPHD
(see Figure 2, page 5 ) is set at the factory to the value specified in Section 2 ,
page 2 . If the maximum back pressure is exceeded, this switch trips. This causes the message
"Back pressure high" or "Clean the lint screen" to appear on the controller display to indicate that
a lint screen may be blocked. It does not stop dryer operation. It may be necessary to adjust this
switch slightly once the machine is connected to the laundry ductwork. Air pressure in the ple-
num for this dryer may be affected by the ductwork configuration and by adjacent dryers.
It is difficult to adjust SPHD with a manometer. Initially, this switch was set with the dial alone
(the marks on the dial show the specified value). If the message appears too frequently, turn the
dial to a higher value. If the message does not appear when it should (when a lint screen is
blocked) turn the dial to a lower value.
