Gas Type Conversion Procedure
The 620130 & 630130 are approved for Natural and LP gas types only.
Conversions to Butane or TLP gas are illegal.
For warehouse gas type conversions the burner operation and gas
tightness testing must be completed by dry firing the water heater or
fully assembled burner/gas control assembly. Do NOT leave the main
burner on for more than 30 seconds if dry firing. Where gas is
unavailable for testing gas type conversions must NOT be conducted.
1. Isolate gas supply to the water heater.
2. Remove the access cover (outdoor models) or the front metal cover and gas control
plastic cover (indoor models).
3. Disconnect gas supply pipe and remove the union or elbow from the gas control.
4. Disconnect the following from the gas control -
a. Piezo igniter lead. b. Pilot feed pipe.
c. Thermocouple. d. Burner feed pipe.
5. Remove the holding screw from the burner mounting bracket.
6. Remove the burner assembly.
7. Remove the gas control top cover.
8. Remove the gas control from the sheath by releasing the spring clip.
9. Change pilot injector to suit gas type. Ensure gas tight joints.
10. Change burner feed pipe and main burner injector to suit gas type. Ensure gas tight
joints.
NOTE: The burner-connecting pipe MUST be changed from a fully rounded
type suitable for Natural or TLP Gas to a partially flattened type when
converting to LP or Butane Gas. The reverse applies when converting from
LP or Butane Gas to Natural or TLP Gas.
11. Fit primary aeration shutter when converting to Propane, Butane or TLP gas, remove
the primary aeration shutter or open fully if converting to Natural gas.
12. Refit burner assembly ensuring joints are gas tight.
13. Fit replacement gas control and lock into place on the sheath.
14. Refit the gas control top cover.
15. Reconnect the following to the gas control –
a. Piezo igniter lead. b. Pilot feed pipe.
c. Thermocouple. d. Burner feed pipe.
15. Reconnect gas supply line. Ensure gas tight joint.
16. Restore the gas supply.
17. Light pilot. Ensure lighting instructions, provided on the access door (outdoor
models) or the front of the water heater (indoor models), are carefully followed.
18. Test operation of main burner.
19. Test for gas leaks using soapy water solution.
20. Fit manometer and check burner gas pressure.
21. Check flame quality and if necessary adjust aeration shutter. On LP & Butane Gas the
normal position is fully open, on TLP gas the normal position is 10mm open).
22. Change rating label details and fit new gas type labels.
23. Refit access cover (outdoor models) or the front metal cover and gas control plastic
cover (indoor models).
