Page 6: General Information
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. -

The Honeywell R7284 oil primary control’s reset button is the “i” button, the R7184, R8184 and Wayne control is the big red button. Pressing the reset button and restarting the burner more than once with the burner not lighting could cause oil buildup in the firing chamber. This will... - Page 8 (push and hold for 3 seconds if it is an older style safety check and remains in standby Wayne control), observe burner sequence of operations.

Page 10: Burner Does Not Light, Honeywell Control Remains On Standby
Troubleshooting tables on pages 10-11 are specific to burners that come equipped with an oil primary control, and these sections only apply if the general troubleshooting guide tells the licensed contractor to consult these sections while servicing the burner. NOTE: This section refers to Honeywell R7284 and R8184 series controls. The R7284G and R8184G control use a LED light to display the troubleshooting status, and the R7284P control comes with a display screen that will output the current operating state of the burner or any troubleshooting errors that might arise in normal burner operation. -

Intermittent flame failure occurs during a “call for heat” If the oil primary control stops sensing a flame after the flame has been proven and the trial for ignition timer has expired, the oil primary control enters a limited recycle mode where it will de-energize the burner for one minute, while the LED light will flash for 2 seconds on, and 2 seconds off. -

Make sure system is electrically energized, check circuit breaker, fuses, and close system switch if provided. Press and hold the oil primary control i button for two seconds and release (big red button for three seconds for old Wayne control). Set thermostat (controller) to “call for heat”. ... -
Page 20: General Installation Information
FUEL PUMPS Model EHASR, EHA and EH oil burners are provided with single stage 3450 RPM fuel pumps with the by-pass plug removed for a single pipe installation. This is satisfactory where the fuel supply is on the same level, or above burner, permitting gravity flow of oil. -
Page 21: Fuel Tanks
FUEL TANKS Local codes and regulations must be followed regarding tank and burner installation. Check existing tanks for water and sludge accumulation; clean if necessary. Also clean or replace existing piping. ELECTRICAL WIRING OF BURNER The oil burner is shipped completely wired. It is only necessary to supply the line voltage circuit, thermostat and limit circuit. -
Page 22: Air Supply For Combustion
In order to install or change the nozzle, the oil gun assembly needs to be removed from the burner. The EHASR, EHA, and EH burners has an arrow decal that lines up with the leading edge of the oil gun slot cover plate. This will help with re- installing the oil gun in the proper position once the nozzle has been installed. - Page 23 Figure 7 EH/EHASR Oil Line Assembly Fitting 2.

Page 33: Final Checks
FINAL CHECKS Be sure all screws are locked and the controls on heating unit are adjusted in accordance with the heater and control manufacturer’s instruction sheets. Note: O % should be over 3 %, and for CO emissions the lower the better but, typical applications for pressure washers should be under 250 ppm, and under 125 ppm for boilers. -
