Table 16 – Combustion Settings

It is required to use a combustion analyzer to verify final adjustment according to

the combustion chart (Table 16). Failure to do so could result in serious personal

injury or death.

It is very important that this conversion be set within the recommended CO

measurements listed in Table 16. Visually looking at the burner does not deter-

mine combustion quality. Failure to measure combustion with a Combustion

1. When low fire settings have been obtained, flip DIP switch seven (7) to its original (OFF) position. This will

return the appliance to normal mode.

2. Flip DIP switch six (6) to ON (high fire). Again check combustion readings with a combustion analyzer.

3. When complete, flip DIP switch six (6) to its original (OFF) position. This will return the appliance to nor-

mal mode.

4. Allow appliance to operate normally. Ensure it is operating properly.

5. Reinstall the appliance front cover.

If the readings obtained are lower or higher than the combustion readings in Table 17, use a T40 Torx key to

adjust the offset screw in a clockwise (positive) or counterclockwise (negative) direction (approximately 1/4

turn). See Figure 19. Check your combustion values. Repeat this procedure until the values obtained on the

combustion analyzer agree with those stated in Table 16.

NOTE: If the appliance makes a whistling sound (harmonics) at low fire, adjust the offset screw in a

clock- wise (positive) direction (approximately 1/8 turn). Check your combustion values and ensure they

agree with those stated in Table 16 before proceeding.
