FLAT FLAME TM BURNERS ORIFICE PLATE INSTRUCTIONS
All 4832 Burners have an orifice plate in their main air connection. Plates are mounted as shown in Figure 5 to give flame clockwise spin (viewed from rear of burner). 4832-2 thru -7
Pressure tap on main air flange must be on side opposite plate handle, as indicated by arrows. If necessary, rotate main air flange to achieve this.

Spin
For field conversion of -5 and -6 sizes from gas to dual-fuel, position orifice as shown in Figure 6. For conversion of other sizes, orifice is positioned per Figure 5. Pilot and flame detector must be installed so spin carries pilot flame toward the flame detector (Figure 7). If spin is counterclockwise, reverse pilot and flame detector positions.
