MAINTENANCE
Wayne Combustion Systems recommends yearly inspection/service of your oil heating system by a qualified service
agency or individual.
A qualified service agency or individual must be:
Licensed or certified to install and provide technical service to oil heating systems.
Experienced with all applicable codes, standards and ordinances.
Responsible for the correct installation and commission of the equipment.
Skilled in the adjustment of oil burners using combustion test instruments
APPROVALS
This burner complies with ANSI/UL Standard 296 and is for use with No. 1 fuel oil or No. 2 fuel oil and is UL listed for use
with Group I or Group II primary safety controls. The states of Massuchusetts, New York and local approvals are shown
on the burner’s nameplate label. All burners must be installed in accordance with the National Fire Protection Association,
and in complete accordance with all local codes and authorities having jurisdiction. Regulation of these authorities takes
precedence over the general instructions provided in this manual.
MANUAL ORGANIZATION
This manual is organized so that the licensed contractor can troubleshoot the service issue with the burner by working
through the GENERAL TROUBLESHOOTING GUIDE on page 7. The GENERAL TROUBLESHOOTING GUIDE is
organized by the performance issue or “problem” requiring attention. Each problem will list potential root causes that may
result in the problem listed in order from most likely to least likely, and the solution to correct each root cause that may be
affecting burner performance. The solution listed for each root cause will reference supplemental information regarding
normal burner/component operation and service instructions depending on the problem and root-cause. If this is a new
installation see GENERAL INSTALLATION INFORMATION on page 20.
MODEL DIFFERENCES
The EHASR burner utilizes unique air cones and oil gun assemblies to optimize burner performance in its rated firing
range. The air cone is a single piece construction and is fixed to the air tube. The oil gun depth is set in reference to the
fixed air cone The EH and EHA have the flamelock attached to the nozzle adaptor on the oil gun, this allows the burner to
have a variable gun depth setting based on the firing rate needed. An EHA burner is different from a EH because the EHA
uses an oil pump that is rated up to 3 gal/hr, while the EH model will use a larger pump that is rated up to 7 gal/hr to attain
the higher firing rates.
BURNER COMPONENTS
The EHASR, EHA, and EH model burners are constructed with components of varying design. For example, the ignition
device may be an iron core transformer or a solid state igniter. Both devices perform the same function, and they use the
same troubleshooting methodology. There are also two distinct types of motors utilized by these burners. The “Permanent
Split Capacitor” or PSC motors (silver in color) utilize a thermal protection device that automatically resets when the motor
cools down. The “Split-Phase” motors (black jacket) utilize a manual reset thermal protector. Appliance or equipment
manufacturers may specify one type of component over another. Please contact Wayne Combustion Systems for
assistance with replacement component selection.
Read this manual carefully and in it’s entirety prior to performing any maintenance or service on
the burner.
