Section 15 - Start-Up Procedures
Waste Oil Burner Start-Up
1. Make sure the main electrical service for the heater is turned off, and locked out.
2. Fill the oil supply tank with an approved fuel to a level that is above the pick-up tube check valve.
3. Check for proper draft in the chimney. The draft must read -.02 W.C. cold.
4. Make sure there is air pressure at the heaters air filter/regulator, set it at 12 PSI. Set the primary regulator on the air
supply line to 30 PSI.
5. Set the fan/limit control slide switch to automatic.
6. Check the combustion air adjustment baffle for proper setting. Refer to Section 17, Flame Adjustment.
7. Set the room thermostat below room temperature (if applicable).
8. Turn the main electrical service ON.
9. Push the reset button on the oil primary control for 3 seconds.
10. Flip the lighted rocker switch for preheating on the burner electrical box to the ON position (pre-heater OFF the
light is off, pre-heater ON the light is on.).
11. Prime the fuel supply pump. Refer to Section 16, Priming the Fuel Supply Pump.
12. If using waste10W-50W oil or automatic transmission fluid for fuel, flip the pre-heater rocker switch on (light ON, and
wait 5-7 minutes for the pre-heater assembly to reach operating temperature. Leave the pre-heater switch OFF if
using No. 1 or No. 2 fuel oil.
13. Turn the room thermostat up above the room temperature (if applicable). The burner will now fire, check the sight
glass on the rear of the burner also inspect the flame through the inspection port. Refer to section 17, Flame
Adjustment pages 29-30.
14. Adjust the burner air filter/regulator to 12 PSI, and the primary air regulator to 30 PSI. NOTE: 12 PSI on the air
filter/regulator is the starting point, you may need to adjust from there when setting the flame. See pages 29-30.
15. Adjust the fuel pressure gauge on the left side of the burner to read 7lbs.. NOTE: Adjust the knob on the fuel regula-
tor clockwise to increase pressure, and counter clockwise to decrease pressure to the burner. The oil pressures listed
above are a starting point, you may need to adjust from there when setting the flame. Refer to section 17, Flame
Adjustment pages 29-30.
16. Adjust the barometric damper to obtain a draft of -.06 W.C. while the heater is hot and operating. NOTE: It is VERY
IMPORTANT that the barometric damper is set to the required settings to ensure the natural draft of exhaust gases.
See Section 5, Draft , page 11.
17. Depending on the type of fuel used, the elevation, temperature, and oil viscosity, the combustion air baffle will need
to be adjusted for optimum performance. Refer to section 17, Flame Adjustment pages 29-30.
The combustion air baffle is NOT factory set
