Section: Start the Burner

2.Push in on pin (G) to disengage the motor from the damper shaft and cam stack. Rotate the damper shaft by hand to place the adjustment cams in a position where their adjustment scale can be easily seen. Release pin (G) to secure the damper shaft and cam stack to the motor.

3.Using the wrench (C) supplied with the damper motor, adjust the blue low fire cam (D) to the initial setting listed in Table 3.

4.Using the same wrench, adjust the red high fire cam (H) to the initial settings listed in Table 3.

5.To adjust the high fire transition, use a small straight edge screwdriver. For high/low firing burners, turn the white adjustment screw located in the orange transition cam (J) until the cam indicator is half way between the high and low settings on the scale. For modulating burners the orange transition cam is not used.

6.After setting all the cams, make sure the damper shaft and cam stack is set between its low fire setting and its high fire setting. (If you don’t it may not move when it is powered.) Push in pin (G), move the damper by hand so that notch (E) is between the low fire setting and high fire setting on scale (F), then release pin (G) to re-engage the motor. When the motor is powered it will go to its low fire setting.

7.This initial setting should be adequate for starting the burner at low fire. Once the burner is in operation, the air setting will be adjusted for best performance as discussed later in this manual. Don’t forget to re-install the cover after all adjustments have been made.

The damper plate is attached by screws to its shaft, and bears

against a flat on the shaft for alignment. The shaft is secured to the damper motor by a sleeve coupling with two setscrews bearing against the damper shaft and two more against the motor shaft. The motor shaft has a flat matching the one on the damper shaft. The flats on the damper shaft and the motor shaft should be aligned so that the position indicator in the damper motor reads accurately. The best way to align the flats is to tighten the setscrews that bear against the flats on the shafts first, and then tighten the ones that bear against the round surface of the shafts afterward.

The test for proper alignment is to disengage the damper motor from its shaft using the disengaging pin (Item G in Figure 10B) and rotate the damper plate to its full closed position. The position indicator should point to 0° within +/- 5° tolerance.
