System Setup

SYSTEM SETUP:

Figure 1 shows a typical oil-fired appliance and the expected ranges of several readings taken at various locations in the system. Note: If a vent pipe reducer is required, use a smooth walled gradual reducer. Place it at the venter inlet as shown in Figure 1.

1.Set the choke plate in the power venter, or extension kit, to its full open position. Set the draft control adjustment weight to its midpoint position.

2.Adjust the thermostat so that the unit will run continuously. Allow the unit to operate for 5 to 10 minutes to ensure stack temperature stabilization.

3.Find out the manufacturer’s recommended over-fire or breeching draft. Close the choke plate on the SWG until the draft above the draft control reads approximately 0.04” w.c. greater than the recommended breeching draft. Example: If the appliance manufacturer recommends a 0.02” breech draft, adjust the choke plate to get an approximate 0.06” draft above the draft control.

4.Adjust the barometric draft control to obtain the manufacturer’s recommended draft over-fire or at the breech. The draft control gate should be open approximately half its full swing during normal operation. This allows the gate to swing open or closed depending on changes in atmospheric pressure or operating conditions.

5.If the proper draft cannot be obtained at the breech or if the gate does not open as described, then adjust the choke plate in the SWG to reduce or increase the airflow. Re-adjust the draft control to obtain the required draft, since moving the choke plate will change the system draft.

Procedure for adjusting the pressure switch

•Turn pressure switch adjustment clockwise until the burner quits.

•Turn counter-clockwise slowly until the burner starts.

•Turn an additional 1/4 to 1/2 turn counter-clockwise.

Note: Every installation will require unique pressure switch adjustment.
