SECTION 13: CONVERSION BETWEEN GASES

SECTION 13: CONVERSION BETWEEN GASES 13.1 General

Conversion between gases will require a change of burner injectors and the gas valve re-commissioning to the new conditions.

13.2 Burner Conversion

Conversion of the burner assembly from one gas to the other is the same for all types of heaters.

1.Remove the burner compartment cover as shown on Page 27, Section 15.2.

2.Remove the 4 screws holding the manifold and pull out the manifold.

3.Remove inshot burners by rotating them and sliding out the bracket.

4.Remove the main burner injectors.

5.Replace with the injectors for the new gas ensuring a gas tight seal.

6.Refit all components in reverse order.

13.3 Gas Valves

All gas valves used on the CTCU have pressure regulators that may be set to operate on natural gas or LPG.

Conversion is carried out by re-setting the burner pressure to the value in the data table during commissioning. See Page 6, Section 4.3. Ensure that the gas inlet pressure to the heater is correct for the new gas, and that the gas supply has been purged of the old gas.
