General Information - Wayne EHASR-DC Manual

Read this manual carefully and in its entirety prior to performing any maintenance or service on
the burner
.
OPERATING VOLTAGE
The EHASR-DC and EH-DC burners covered in this manual typically receive operating voltage from the equipment's dc
charging system. These systems are often referred to as "12Vdc systems"; however, the actual voltage may vary between
12.5Vdc and 14Vdc depending on the system and the operating load. Components of the burner may have markings
indicating "12Vdc"; however, these components have been designed to operate at the voltage variations provided by the
equipment's charging system.
WARRANTY
Wayne Combustion Systems warrants its burner's specifically to organizations that have purchased it for resale, including
your dealer. If you have a problem with your burner, or its installation, you should contact your dealer for assistance. For a
full description of the warranty see page 37.
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 using combustion test instruments to adjust and troubleshoot oil burners.
APPROVALS
This burner is design certified by UL to comply with ANSI/UL Standard 296 and is for use with No. 1 fuel oil or No. 2 fuel
oil. All burners must be installed in accordance to the original equipment manufacturers instructions. If installation
instructions are not found in the OEM manual, use this manual as a guide and contact the equipment manufacturer for
installation help with our burner.
MANUAL ORGANIZATION
This manual is organized so that the licensed contractor can troubleshoot 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 22.
MODEL VARIATIONS
The EHASR-DC burner utilizes unique air cones and oil gun assemblies to optimize burner performance in its rated firing
rate 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-DC burner utilizes a flamelock that is 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 EH-DC uses an oil pump that is rated
up to 7 gallons per hour to provide the necessary fuel capacity.
BURNER COMPONENTS
The EHASR-DC and EH-DC model burners are constructed with a 12Vdc solid state igniter. Certain DC burners
specifications are built with a timer and flame detecting cad cell that will de-energize the 12Vdc igniter after the presence
of flame has been proven. The purpose of the timer is to reduce the overall electrical current consumption of the burner
when the power supplied from a generator is limited. The EHASR-DC and EH-DC burners are factory equipped with
"Permanent Magnet" motors that utilize a simple brush design making the motor maintenance free. Equipment
manufacturers may specify one type of component over another. Please contact Wayne Combustion Systems for
assistance with replacement component selection.
