Extended Appliance Shutdown - Thermo Pride OPA Installation And Service Manual

All installations and services must be performed by qualified service personnel.
NOTICE: Remind the homeowner of the importance of monthly filter
inspections during operation to ensure maximum operating efficiency.
F. Extended Appliance Shutdown
: Do not attempt to start burner when:
• Primary reset has been engaged more than two times.
• Excess oil has accumulated in the combustion chamber or beneath the
burner assembly.
• The combustion chamber or the heat exchanger is full of fuel vapor.
• The combustion chamber is very hot.
Should the appliance be shutdown or turned off for an extended period of time,
several steps can be taken to help insure a smooth and reliable restart of the
heating system.
ON SHUTDOWN:
1. Close oil supply (or manual shutoff) valve.
2. Disconnect all electrical power to the unit.
3. Fill the oil tank to reduce water condensation in the tank.
4. If the shutdown period will exceed one heating season, an oil stabilizer
should be added to the oil tank. Consult your oil supplier for
recommendations.
ON STARTUP:
1. Have system inspected and started by a qualified heating contractor.
2. Check oil level in tank. If the tank has not been filled with fresh oil, inspect
the remaining oil for signs of contamination with water, algae, dirt or other
impurities. If excessive, consult your oil supplier for recommendations.
3. Change the oil filter cartridge and clean the canister.
4. Set the room thermostat above room temperature.
5. Open all valves in the oil supply line.
