Tip: Perform combustion analysis after installation.
Gas Line Connections
Gas supply connection procedures.
- Shut off gas supply at main valve
- Install sediment trap before gas valve
- Use approved pipe compound on threaded connections
- Install manual shutoff valve within 6 feet of unit
- Pressure test: 14" WC for 10 minutes (no drop)
- Check manifold pressure: Adjust as specified
- Leak check: Use bubble solution on all connections
WARNING! Gas connections must be performed by licensed gas fitter.
Startup and Commissioning
Initial startup and system verification.
- Verify all connections are secure
- Restore power and gas supply
- Set thermostat to heat mode
- Check ignition sequence and flame
- Measure temperature rise (35-65°F typical)
- Verify blower operation and airflow
- Test safety controls and limit switches
- Complete installation checklist
Maintenance Guidelines
Routine maintenance procedures.
- Monthly: Check air filter, replace as needed
- Annual: Professional inspection and cleaning
- Seasonal: Test safety controls and operation
- Components: Clean blower, check heat exchanger, lubricate motor if required
