SECTION 4 CHIMNEY INSTALLATION
4.1Failure to provide proper venting of the heater exhaust gases could result in death, serious injury, and/or property damage FOLLOW CHIMNEY MANUFACTURERS INSTRUCTIONS.
4.2Safe operation of any gravity vented heating appliance requires a proper air make-up system to prevent the heater exhaust gases from being drawn into the building. These gases could cause death, serious injury, and/or property damage. Exhaust fans, paint booths may cause draft problems.
4.3Never vent this heater into another heating appliances chimney. Never vent into ‘Class B” chimney. Gas heaters use “Class B” chimney, it is rated for a much lower temperature than is required for your waste oil furnace. This heater must have its own separate “Class A” chimney.
4.4Inspect and maintain the chimney on an annual basis.
4.5Install a U.L. listed barometric damper in the chimney. Do not reduce or enlarge the vent pipe.
4.6Do not use more than one 90° elbow. Each 90° elbow equals a 10’ run of chimney. The maximum run for the chimney connector is 30’.
4.7To prevent the drawing of exhaust gases into the building, keep the barometric draft control at least 24” from the heater, exhaust fan etc..
4.8Position the draft control as shown. Chimney angle gate pins must be horizontal for proper operation.
4.9Secure all connections in the chimney connector with 3 screws per joint.
4.10The chimney connector clearance to any combustible material is 18”. The “Class A” chimney clearance to any combustible is 2”. Follow the manufacturers instructions.
4.11Do not install heat re-claimers, manual draft controls, or any other type of restrictive control in the chimney.

SECTION 12 FURNACE CONTROLS AND
OPERATION
12.1Room Thermostat:
The room thermostat automatically controls the on/off operation of the heater according to the setting of the desired room temperature.
The thermostat works in conjunction with the oil primary safety control.
12.2Oil Primary Safety Control/Cad Cell:
The oil primary control is mounted on top of the burner’s electrical box. When the thermostat calls for heat the oil primary control starts the burner by switching on the air solenoid valve, ignition transformer, combustion air blower, and the fuel pump. The oil primary control works in conjunction with the cadium sulfide cell (cad cell). The cad cell is mounted inside the burner cover, and faces the flame. The cad cell monitors the light level inside the combustion chamber to insure there is a flame present. If there is a loss of flame the primary control will go into its recycle mode. After 1-2 minutes the primary control will restart the burner. When this happens if there is a flame present, the burner will continue to function. If on start up no flame is established in 30 seconds the primary control will lock out.
CAUTION: Do not press the reset button more than twice. If the burner fails to start refer to Section 17 Trouble Shooting.
12.3 Fan/Limit Control
The fan/limit control performs 3 functions. The fan/limit control monitors the temperature of the air inside the cabinet. When the air reaches a set point (usually 120º F) it will switch on the heater fan. When the temperature in the cabinet drops below 90º F the fan/limit control will turn the fan off.
