BURNER GAS PRESSURE TESTING AND ADJUSTMENT
The burner gas pressure must be checked and adjusted (if required) as part of
the commissioning procedure. Refer to gas details in the table on page 34 or
check the rating label of the water heater for the burner test point pressure with
the burner operating.
To check and adjust the burner gas pressure of the water heater:
1. Remove the access cover.
2. Close down the gas control (refer to “Close Down Procedure” on page 47)
and close the gas isolation valve to the water heater.
3. Using a small flat
bladed screwdriver,
lever and remove the
black plastic cover
surrounding the
burner pressure test
point on gas control.
4. Remove the screw
from the burner
pressure test point on
the right side of the
gas control and attach
the manometer hose
to the test point.
5. Open the gas isolation valve fully.
6. Light the water heater and ensure the burner is operating (refer to “Lighting
the Water Heater” on page 43).
7. Take the manometer reading (burner must be operating).
The burner gas pressure should be:
1.0 kPa (±5%) for this natural gas model.
If adjustment is not required, proceed to step 9.
If adjustment is required, proceed to step 8.
