  3. Electrical wiring: Connect to dedicated 120V circuit; proper grounding required.
  4. Venting system: Install according to manufacturer specifications for category IV venting.
  5. Drain line: Connect condensate drain to proper disposal point.

WARNING! Installation must be performed by qualified HVAC technician. Improper installation can cause fire, explosion, or carbon monoxide poisoning.

First-Time Setup

Initial startup and configuration procedures.

  1. System check: Verify all connections are secure and proper.
  2. Gas pressure adjustment: Set manifold pressure to specifications.
  3. Blower speed settings: Configure for proper airflow and static pressure.
  4. Thermostat configuration: Program for optimal heating operation.
  5. Safety testing: Verify all safety controls function correctly.

CAUTION! Never bypass safety controls. Always test carbon monoxide detectors after installation.
