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.

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.
