Type B Solid Cone Spray Pattern Advantages
The Delavan Type B solid cone design offers:
- Uniform droplet distribution throughout the entire spray pattern
- Excellent fuel-air mixing
- Reliable burner startup and ignition
- Stable flame retention
- Efficient combustion performance
- Consistent heat generation
- Reduced combustion irregularities
While Type B nozzles gradually become more hollow at very high flow rates, particularly above 8.00 GPH, the 1.35 GPH model maintains excellent solid cone characteristics for efficient burner operation.

- Inconsistent burner operation
Installation Notes
- Disconnect electrical power and fuel supply before servicing.
- Remove the existing nozzle carefully to avoid contamination.
- Inspect fuel filters and lines for debris or restrictions.
- Install the replacement nozzle according to equipment specifications.
- Confirm the proper flow rate, spray angle, and spray pattern.
- Test burner operation after installation.
- Verify combustion settings if required.
Important: Always replace burner nozzles with the exact flow rate, spray angle, and spray pattern recommended by the equipment manufacturer to maintain proper combustion efficiency and safe operation.
Maintenance Recommendations
- Replace burner nozzles during routine maintenance intervals.
- Keep fuel systems clean and properly filtered.
- Use clean fuel free from water contamination.
- Monitor burner flame characteristics regularly.
- Check fuel pressure settings during service.
- Replace contaminated or worn nozzles immediately.
