4.11 Measuring gas pressure

General rules for gas pressure measurement

1. Shut off the burner.

2. Open the test point connection cover.

3. Attach a silicone hose to the test point connection. Attach a gauge to the other end

of the hose.

4. Start the burner.

5. While the burner is running record gas pressure readings using the instructions

below.

6. Perform adjustments if needed.

7. Shut off the burner.

8. Finally close all the test point connections and remove measurement equipment.

Make all adjustments when the burner is running!

All stated pressure values are only for reference. The actual values may

vary depending on operating conditions.
