Codes and standards
1. EZ-1/2/3 application information
Conversion burners
General information — conversion burners
Carlin Elite burners are shipped for general distribution, with fuel units set
for 100
psig
. Burners are usually shipped assembled, with a universal slip-
on flange. Air tubes and housings will be installed or shipped in separate
boxes for field assembly.
Before installing the burner, follow guidelines in this manual to ensure you
are using the correct nozzle, head-positioning bar and air tube length.
Oil nozzle selection — conversion burners
If oil nozzle selection information for the application is not available from
appliance documents, you can use Table 1, page 4, for an initial nozzle
selection for the application. Specific applications may require testing more
than one nozzle to obtain both clean combustion and a good match of flame
shape to the combustion chamber.
OEM burners
General information — OEM burners
Elite burners manufactured for heating appliance manufacturers (OEM’s)
are generally identical to conversion burners (distributed through supply
houses) with one or more of the following differences:
• Burners may be fully assembled, with a welded flange set at the proper
insertion depth and pitch for the appliance.
• Burners may be installed on the appliance or shipped in a separate
carton.
• Burner nozzles may be installed in the burner, bagged or tied onto the
burner chassis, or located in the appliance packaging.
• Head positioning bars may be installed or bagged to the burner chas-
sis. Up to seven bars may be supplied. Use the bar with a range that
includes the nozzle size used.
Elite burners with the “-HP” suffix are only supplied through the heating
appliance manufacturer (OEM) market. These burners differ from standard
models as follows:
• Fuel unit pressure is factory-set between 130 and 150
psig
. Check
heating appliance manufacturer’s specifications for the correct pressure
setting.
• The air band scale is calibrated for the fuel unit pressure. Set the air
band to match the nozzle size installed. See page 11 in this manual
for further information.
Installing OEM burners
• Burner flanges are welded to the air tube to ensure the correct pitch.
Do not attempt to adjust the pitch using the air tube locking screws.
• Burners shipped installed on the heating appliance are supplied with
four extra shipping screws in the air tube. These screws do not need to
be removed, and can remain in the air tube for the life of the burner.
Oil nozzle selection — OEM burners
• Use only the nozzle specificed in the heating appliance manufacturer’s
manual or burner supplement.
