The "1-D" designation indicates a specific capacity range and electrical supply (3-phase alternating current).
: The gas supply line must be thoroughly purged of air or inert gas before the first start-up.
Preventative maintenance prolongs the lifespan of the burner and prevents costly emergency shutdowns. The service manual mandates an annual inspection checklist. Routine Maintenance Steps
3-phase, 400V, 50Hz control voltage typically stepped down to 230V. Main Assemblies
Monitor gas dynamic pressure; clean the ionization probe/UV cell. Defective fan, blocked pressure hoses, or faulty switch. Weishaupt G7 1-d Service Manual
) to ensure it meets the minimum threshold outlined in the manual.
The service manual provides a detailed fault code table. Common issues with the G7 1-d include:
Open air dampers; re-verify diffuser disc positioning via the manual. 7. Genuine Spare Parts and Documentation
When the Weishaupt digital combustion manager detects a fault, it will lock out the burner and display a specific flash code or digital error code. Burner Fails to Start The "1-D" designation indicates a specific capacity range
