Electrical Information

This heater operates on a dual-voltage system (120V/240V), requiring proper grounding and adherence to local electrical codes. For safety, a dedicated circuit breaker is recommended. Before installation, it’s essential to configure the voltage settings correctly to ensure optimal performance.

Recommended Installation Tips

  1. Location Matters: Install the heater outdoors in a well-ventilated area with proper clearance as the manual specifies. Avoid placing it near flammable materials or in confined spaces.
  2. Gas Line Requirements: Use appropriately sized natural gas lines for consistent fuel flow. Consult your local codes or a licensed professional for proper sizing.
  3. Plumbing Connections: Utilize 2-inch plumbing for optimal flow and minimal pressure loss. Ensure connections are leak-free.
  4. Voltage Configuration: Confirm the correct voltage setting before connecting to the power. For safe wiring, a licensed electrician is recommended.
  5. Regular Maintenance: Inspect and clean the heat exchanger and burners to maintain efficiency and extend the heater’s lifespan.
