Ductwork: Ensure proper return and supply air connections.

WARNING! Gas appliances can be hazardous; installation must comply with all local codes and manufacturer specifications.

First-Time Setup

Complete installation verification before initial startup.

Gas pressure adjustment: Set manifold pressure to 3.5" WC for natural gas.
Blower speed selection: Adjust dip switches for proper airflow (CFM).
Thermostat configuration: Connect standard 24V thermostat wires.
System checkout: Verify proper ignition sequence and flame characteristics.
Combustion analysis: Check CO levels and temperature rise.

CAUTION! Only qualified HVAC technicians should perform initial setup and adjustment.
