IMPORTANT INF OR M A T ION Waste oil contains various unknown materials and may also contain random amounts of gasoline or other volatile fuels. Specific safety and handling precautions should be considered when cleaning, maintaining and operating waste oil heaters. It is recommended to use a filter or some kind of strainer when pouring waste oils into the storage tank(s). This will increase chances of catching any particulates prior to the pump filter(s) to insure a cleaner fuel source.
NOTICE To insure the best performance, optimal efficiencies and heat output of the heating unit, it is recommended and necessary to become familiar with your unit and the procedures needed with initially starting, running, cleaning and maintaining the heating unit. Improper installation and or neglected maintenance will void the warranty. Avoiding maintenance of the unit can cause over fire or over heating of the unit and potentially create cracks in random welded areas of the heating unit.

HANGING OR MOUNTING THE HEATER When mounting the heater, make sure the heating unit is at least twenty inches (20”) away from any combustible materials. A minimum of thirty six inches (36”) away from the front of the unit is recommended. Notes: 1. All illustrations and specifications are based on current information available at the time of publication approval. MorrHeat reserves the right to make product changes at any time. These heaters are designed for indoor commercial and industrial use.
VENTING INSTALLATION 1. When installing the vent pipe, be sure all connections are fastened correctly to insure no leaks and proper draft is achieved. Minimum draft through the unit is, -.02- when checking through the sight or flame inspection port directly above the burner assembly, with draft meter. Draft up the stack must be -.04 to -.06 inches of water column when checking a draft meter for proper draft readings. 2.
• Be sure when priming or bleeding the fuel pump that you allow enough time to completely burp any and all air within the system out of the fuel pump and fuel lines. If any skips or slight interruptions are still present in the system, it is likely the unit will not properly ignite or run without a steady and consistent fuel supply. The flame sensor needs to recognize flame in the chamber or it will not ignite.

Oil Burner Technology MorrHeat’s waste oil burner technology improves the efficiency of the oil burn process by continuously burning the waste oil with no interuptions. The waste oil enters into the Oil Pre-Heater Block and is pre-heated to a specific temperature setpoint. Then compressed air from the air compressor is infused with the oil prior to spraying out the nozzle by breaking up the oil particles into a finer mist or spray.
Oil Burner Components • Igniter Transformer: Supplies high voltage to the electrodes generating electrical arc igniting the oil. Transfers the high voltage from the igniter transformer to the electrodes. • Solenoid Oil Valve: Opens when burner is running and closes when burner is not running eliminating bleed back of oil out of the Pre-heater block. • Air Band: Adjusts amount of air introduced into the combustion chamber.
• Electrodes: Provides continuous high voltage electrical arc from electrode to electrode igniting the waste oil as it is being sprayed out of the nozzle. • Nozzle: Low-pressure nozzle. (3 pc. and cleanable) • Flame Cone: Flame cone forces the flame into a swirl pattern improving the flame for a complete burn. • Burner Motor: Multitask motor turns the burner blower and integrated air creates combustion and atomization air at the same time.
Initial Start Procedure 1. Make sure the heating unit and all components have been properly and securely installed. 2. Check that all electrical connections and hook-ups are properly wired and connected. 3. It is recommended prior to priming the fuel pump and bleeding the air to pre-fill the fuel filter to help speed up the process. For a secondary check you can always pressurize the fuel lines to eliminate any potential leaks in the line or fittings.
SUGGESTED MAINTENANCE IT IS RECOMMENDED THAT YOUR FACILITY GETS ON A REGULAR MAINTENANCE SCHEDULE AND OR SET REMINDERS OF CLEANING AND MAINTENANCE OF THE HEATING UNIT, TANK, OIL FILTER, AIR FILTERS AND ALL OTHER WORKING COMPOENTS AND CONSUMABLES THAT MAY NEED ATTENTION OR REPLACED BEFORE OR DURING SEASON.
NOZZlE ASSEMBLY REFERENCE When cleaning, inspect all three pieces thoroughly. Electrode Adjustment Reference 3/8 from tip/center of nozzle flush with the Electrodes.
Troubleshooting ▲ Most likely || ▶ Less likely || ▼ Least Likely Problem 1. Heater shuts off 2. Loss of prime overnight 3.Fails to Start 4. Reduced air pressure and can’t increase 5. Hard starting (Diminished flame) Cause ▲ ▲ ▶ ▼ Manual reset Vacuum air leak in air line Plugged filter or tank empty Plugged pump screen ▲ Vacuum leak ▲ Inadequate fuel supply ▶ No pressure ▶ No pre-heat ▶ Auto start circuit not functioning ▶ No arc ▶ No air pressure ▲ Gauge may be bad.
6. Heater cycles frequently, without set temperature being reached ▲ Heater over firing ▶ High limit safety switch bad ▼ Temperature setting wrong ▲ Investigate and locate reason for over firing. I.e nozzle eroded, pump not functioning properly, decrease pump motor speed. ▶ Replace high limit fan safety switch ▼ Check temperature setting and adjust as necessary. 7. Heater rumbles and ▲ Pump setting wrong excessive heat blow back from flame vision port ▼ Draft incorrect. If proper draft can't be achieved.
Warranty Information - 10 Year MorrHeat warrants the materials and workmanship will be free of defects for the duration of the warranty specified. Warranty is valid from the date of delivery and warranty card must be sent in to MorrHeat within 30 days of delivery date. MorrHeat is not responsible for damaged goods. Please check your shipment for any damages.
WARRANTY CARD REMINDER: Warranty coverage is specific to the materials and workmanship of the unit and does not cover additional labor and freight charges unless written authorization is provided. Warranty assures and covers welds when maintained and used properly but does not cover stress cracks caused by excessive heat or over fire. Bad draft, back draft or simply too much fuel and too large of flame are a direct cause of an over fire or over heated unit.
