Why is Pipeline Natural Gas Harder to Start with the Manual Start Version?

Reasons Analysis

1. Gas Supply Pressure Differences

   • Pipeline Natural Gas: The supply pressure is generally lower (0.25 PSI ~ 5 PSI), making it harder to achieve the ideal fuel-air mix quickly.
   • Bottled Natural Gas: High pressure (30~40 PSI) ensures a steady gas flow, making ignition easier.

2. Starter Speed Differences

   • Electric Start (PDE): Provides high and stable cranking speed, compressing the fuel mixture effectively for reliable ignition.
   • Manual Start (PDM): Lower and inconsistent speed makes ignition harder, especially with low-pressure gas.

3. Fuel-Air Mixing Efficiency

   • Low-Pressure Conditions: Pipeline natural gas's low pressure hinders efficient mixing of air and gas, affecting ignition concentration.
   • High-Pressure Conditions: Bottled natural gas's high pressure ensures better mixing efficiency.

4. Ignition System Requirements

   • Manual start requires a higher fuel concentration for successful ignition, making low-pressure natural gas more challenging.

Suggested Solutions

1. Choose the Electric Start Version The electric start version (4500PDE) performs better with pipeline natural gas, especially in low-pressure conditions.

2. Consult a Professional For pipeline natural gas, consult a technician to ensure proper installation and pressure settings.
