SAFE USER CHECKS

What you can check safely

  1. 1. Record H.01.00 and the full model label (Startec Premix 24, Startec Premix 30). The published meaning applies to the manufacturer-described model family, not every boiler of this brand.
  2. 2. If you smell gas, do not touch switches, plugs or controls; move to safety and call the local gas emergency number from a safe location.
  3. 3. If there is no gas smell, observe the external pressure display and any visible warning indicators. Never open the casing, fan, flue, gas valve or electrical connections.
  4. 4. Check only items expressly permitted by the manual for that specific model. If the fault relates to combustion, gas, a sensor or electronics, leave diagnostics to authorized service.
  5. 5. If the manufacturer manual explicitly allows a reset, try it only as instructed. Do not repeatedly bypass a safety lockout.
  6. 6. Tell service the code, model, pressure reading, onset and other symptoms. Qualified staff should confirm the cause by measurements.
AUTHORIZED SERVICE

What a technician should confirm

Qualified service must use the model-specific service documentation and suitable measurements. Gas, flue, electrical, heating and refrigeration repairs are not safe do-it-yourself tasks.

Verification after service

After manufacturer-authorized inspection, check that H.01.00 no longer appears during ordinary operation. If the warning returns, stop and contact service again.
