Model 99FRD, 102CRD & EZ-66 Oil Burners — Instruction Manual

3.  Prepare Burner 

(continued)

•  The nozzle line heater needs power when the burner is in standby (no 

call for heat from the appliance). Make sure the nozzle line heater is 
powered directly from the 120 VAC HOT line, not through the appliance 
operating control circuit. The nozzle line heater wiring should be shown 
on the wiring diagram supplied with the appliance/burner unit.

•  The nozzle line heater is supplied with an electrical disconnect harness, 

allowing removal of the combustion head assembly without discon-
necting wires. Position the heater harness disconnect in the rear of 
the blower housing, above the blower access cover. The wire leads to 
the disconnect route through the side of the housing into the junction 
box.

  When first starting the burner, or after the service switch has 

been off for some time, the heater requires about 15 minutes 
to bring the oil to operating temperature.

Figure 14  One-line fuel system

One-line fuel system requirements

See Figure 14. The standard burner fuel unit is a single-stage, 3450-RPM 
oil pump. Apply this fuel unit only on one-line systems where the fuel sup-
ply is on the same level with, or higher than, the burner. This ensures oil 
flow by gravity. Also make sure the total lift does not exceed 8 feet (height 
difference from bottom of oil tank to fuel unit). For other conditions, you 
must provide a two-line fuel system. You may also have to change the fuel 
unit to a two-stage type.

Inspect/install fuel supply

  Inspect the oil supply system. Ensure that the fuel lines are 

correctly sized and installed and that the fuel flow is unob-
structed, the oil tank is clean and only # 1 or # 2 heating oil 
are supplied. Failure to supply a reliable oil flow could result 
in loss of heat and potential severe equipment damage.

Nozzle line heater

•  Oil burners often operate in spaces where temperatures tend to be 

cool, typically 60°F or lower. Cool oil has higher viscosity, which can 
affect atomization, ignition, combustion and fuel consumption. The 
nozzle line heater avoids this problem by heating the nozzle line oil to 
between 120°F and 130°F, resulting in smoother ignition and improved 
combustion.

General guidelines:

•  When installing oil lines, use continuous runs of heavy-wall copper 

tubing if possible.

•  Check fuel unit (oil pump) data sheet for recommended line sizing, lift 

limitations and maximum length.

•  Check all connections and joints to ensure they are air-tight.
•  Use flare fittings. Do NOT use compression fittings.
•  Never use pipe sealing tape. Fragments can break off and plug fuel line 

components.

•  Install a shut-off valve at the tank and one near the burner. (Use fusible 

handle design valves when possible or when required by codes.)

•  Install a large capacity fuel filter (rated for 50 microns or less) near the 

burner.

Fuel unit bypass plug

  The fuel unit is shipped with its  bypass plug not installed, 

intended for a one-line oil system. Install the bypass plug only 
if connecting to a two-line oil system. Operating with the plug 
in place on a one-line system will damage the fuel unit and 
could lead to oil leakage and fire hazard.

  If the fuel line or fuel supply is above burner, never exceed 3 

PSIG pressure at the fuel unit inlet. Install a suitable OSV to 
reduce the pressure. Operating the fuel unit with higher inlet 
pressure could result in fuel unit seal damage, oil leakage 
and potential fire hazard.
