Firing Options | Four options for stage sequencing are available. Select number 1, 2, | |
| 3, or 4 as follows: | |
| #1 | No Lead/Lag: Stage 1 of heater #1 always fires first. The |
|
| remaining stages and heaters will fire in order as demand |
|
| increases. |
| #2 | |
|
| rotated to the next heater. This distributes the work load |
|
| equally among all heaters. |
| #3 | Lead/Lag & Rotate: With this option, heater #1 always fires |
|
| first, then the remaining heaters fire in rotation. Since some |
flue |
| designs require heater #1 to fire first; this option meets this |
|
| requirement while still providing limited rotation. |
