Operating Instructions

Normal operation through thermostat control.

Set thermostat to HEAT mode and desired temperature.
Furnace will initiate startup sequence: inducer motor, pressure check, ignition, main burner.
Blower will start after warm-up period.
System will cycle on/off to maintain set temperature.
For continuous fan operation, set thermostat fan to ON position.

WARNING! If you smell gas, turn off furnace immediately, evacuate, and call gas company from outside.

Maintenance Schedule

Regular maintenance ensures efficiency and longevity.

Frequency	Task	Notes

Seasonal	Visual inspection	Check vents, flame appearance
Annual	Professional service	Combustion analysis, component check
As needed	Clean flame sensor	If experiencing ignition problems
5 years	Blower motor maintenance	Professional service recommended

Care & Cleaning

Basic maintenance tasks for homeowners.

Air Filter: Replace every 1-3 months depending on usage and environment.
Vents: Keep intake and exhaust clear of snow, leaves, and debris.
Burners: Visual inspection for clean blue flame (professional cleaning required).
Drain Lines: Check for obstructions in condensate drain system.

CAUTION! Turn off power before performing any maintenance. Do not attempt internal repairs.
