burner or circulating pump, as the case may be,
responds.
Ensure the external controls are calling for heat.
After ignition the display should read:
2. Gas Rate
Operate the boiler for 10 minutes. Check the boiler
gas rate (see Table 2), ensuring the boiler is at full
output whilst measurements are recorded.
