Study Notes
Preparation for Startup
- Ensure the boiler has a valid inspection certificate before startup or after a prolonged shutdown.
- Review the manufacturer's recommendations for startup and operation.
Pre-Startup Checks
- Verify the boiler's altitude gauge indicates a minimum static pressure to maintain positive pressure at the highest point in the system.
- Ensure the isolation valve between the expansion tank and the heating system is open.
- Check the expansion tank level, and if high, drain and vent the tank to the correct level.
Expansion Tank Preparation
- If multiple boilers share a common expansion tank, follow site-specific procedures to ensure all on-line boilers are serviced.
- Ensure the expansion tank isolation valve is open.
Heating System Preparation
- Start the primary heating loop circulator pump and vent air at high points in the system until a solid stream of water flows.
- If the system has secondary heating loops, start the secondary circulator pumps following site-specific procedures.
Fuel and Air Supply Checks
- Check the fuel and fresh air supplies before startup.
- Verify the temperature setting of the high limit control.
Boiler Controls
- Ensure the boiler control switch on the panel is in the off position before startup.
- Set the control switch to low on boilers with a high-low firing rate control.
- For boilers with a fully modulating firing rate control, set the manual-automatic switch to manual and the flame control switch to low-fire.
Final Checks
- Push the reset buttons on the low water fuel cutoff and high limit control if equipped with mechanical reset devices.
- Ensure all checks are complete before starting the boiler.
