Preparing The Burner For Pump Priming - CLEAN BURN CB-1400 Operator's Manual

Preparing the Burner for Pump Priming

NOTE: It is necessary to allow the burner to warm up at least 15 minutes prior to activating the burner
during the pump priming sequence. The proving switch on the preheater block will not allow the burner
to start until the block is hot.
1. Turn the switch on the wall thermostat to OFF.
NOTE: If your thermostat does not have an OFF setting, disconnect one thermostat wire so the
burner will not run.
2. Turn the main power to the furnace ON.
3. Refer to Figure 5C.
4. Disconnect the oil line at the connector block on the furnace.
5. Position a one-gallon container (minimum) to catch oil which will flow from the disconnected oil
line during pump priming.
NOTE: It is important to thorougly flush the oil line during pump priming so that no dirt/debris
is fed to the burner.
6. Loosen the locking nut on the oil regulator, and turn the knob two to three full turns counter
clockwise so the oil regulator is completely shut off.
7. Loosen the locking nut on the air regulator.
