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.
WARNING:
Waste oil heaters should not be used in any hazardous areas that may contain flammable or
volatile vapors or even combustible dusts. It is not recommended to use a waste oil heater in
any areas that may have chlorinated or similar chemical vapors. This will cause deterioration
& corrosion of the metals the equipment is constructed of (this would void the warranty).
Antifreeze does not burn and will interrupt the performance of the unit and potentially shut
down completely until re-primed and restarted. If too much antifreeze is present just like
water, the unit will not fire. Do not expose units to water, moisture or rain. This is an inside
unit, not designed for outdoor use.
Oils and different Viscosities that can be burnt, but not limited to:
*Used Motor Oils *Transmission Fluid *Hydraulic Fluids *Diesel Fuels
Do not use old contaminated oils or fuels and keep in mind underground tanks and outdoor
oil storage could have unknown amounts of water and moisture, outside barrels will leak
water and moistures through the bunghole.
IMPORTANT:
The instructions and information within this manual are provided to remind you of any
warnings and to assure you have properly and successfully setup the equipment purchased. The information is also intended to help the end user/installer be aware of the operations
and service required for optimal performance. These heaters are recommended for primary
or an auxiliary source of heat but are not recommended for use as the sole source of heat
in case of any expected or unexpected downtime with the unit. If a steady supply of fuel is
not present or interrupted at the burner unit, the burner unit will shut down. Be prepared
with an alternate source of heat to insure the building and all pipes are not at risk of freezing
temperatures.
Taking Delivery of Equipment:
When taking delivery of your equipment, please be sure to check the shipment for any
potential damages (MorrHeat is not responsible for any damaged shipments if signed for
non-damaged). If any damage is identified upon delivery, either sign for as damaged goods
specifically noting in detail the apparent damage / or / refuse the shipment completely and
be sure to file a claim with the shipping company immediately regardless of the damage.

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.
It is important to remember when burning used or dirty oils that contaminants could be
present. Because of various contaminates, be aware of needing to change filters when
needed. Keep the chamber and heat exchanger(s) passageways clean. Make sure the fuel
pump is primed and lines are free of any debris, air bubbles or interuptions.
Draft is just as important as the rest; bad draft can cause serious problems and not allow the
gasses within the unit to correctly leave the heating unit. Correct draft is needed for optimal
performance. Bad draft will cause over-fire or overheating due to bottling up the heat or
creating back pressure back in to the heating unit. If black smoke is present, bad draft, bad
combustion or both is occuring.

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. If proper or desired draft isn’t easily achieved, a third party draft inducer or power vent
may be needed to prevent back draft from occurring (not provided).
3. Install a barometric damper (NOT included) in the stack only if the draft up the stack
exceeds -.08. Draft up the stack must be -.04 to -.06 inches of water column. Check with
draft meter between the top of the heater and damper. The draft should be a minimum of
-.02- checked through flame inspection port.
4. Keep the draft moving. If draft is too slow or bottles up, this could create a back draft and
over-fire or over heat the unit. If a damper is present, losing the damper will increase draft
make sure passageways are clean and clear.
FUEL SUPPLY LINES
• Use only 3/8” ID copper tubing with flare fittings from the tank to the fuel pump assembly
and the fuel pump assembly to the heating unit. Ferrule fittings are not recommended
and Teflon tape is not needed. Using a Teflon tape or liquids that dry on the threads increases the potential of creating a piece or flake of the material that could block passageways.
• Always keep the fuel suction line at least six to eight inches (6” - 8”) from the bottom of
the oil storage tank to prevent sucking water and sludge from the bottom of the tank. Drain water and sludge from the bottom of the storage tank when needed.
• It is recommended to use an inside supply tank vs. an outside or underground tank. If
pulling from an underground tank it is possible a secondary transfer pump would be
needed (Not Provided). Outside storage tanks or barrels can have water mixed in with the
fuel supply. This will create issues (Not Recommended).
• The fuel pump assembly that comes standard with every unit needs to be mounted at
tank level or below. Setting the fuel pump assembly at ground level will function properly. The fuel pump will push oil up to 100ft horizontal & up to 25 ft vertical.
MorrHeat - Most Heat In The Industry - Rev 1/31/2019
Page 7
• 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.
• It is necessary to connect the 3/8” ID copper fuel line from the storage tank to the filter
housing, to the fuel pump inlet that is located on the same side as the bleeder valve. Once
connections are secure, continue the fuel line from the fuel pump assembly to the burner
assembly.
WIRING
• You will need to wire 120v power into the main electrical panel mounted directly on the
backside of the heating unit with separate 20 amp circuit protection using 12-gauge wire.
• Make sure to connect the power line to the black wire and all white wires which are neutral
or common together. It’s very important that the ground wire gets connected to a mounting
point within the main junction box or at least grounded.
• Wires from the main junction box need to be connected to the fuel pump assembly power. Yellow connects to yellow and the neutral or common connect together, which is white to
white.
• The low voltage thermostat needs to be wired to the “T” terminals on the oil primary, located
on the top of the burner assembly. (wire diagram pg. 10)
NOTICE
Installation and use of this product shall be in accordance with the standard for oil burning
equipment ANSI/NFPA 31-2016 along with the national electric code ANSI/NFPA 70-2017, the
requirements of the inspection authorities having jurisdiction.

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. The
electrodes mounted above the nozzle provide an electrical arc across the electrodes to
ignite the fine oil mist as it sprays out of the nozzle. Once ignited the flame is forced
into a vortex caused by the burners blower and flame cone providing a very efficient and
thorough burn.
(See page 12-13 for parts & components)
MorrHeat - Most Heat In The Industry - Rev 1/31/2019
Page 10
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. Air
band is adjusted at the factory for optimum performance, closed to 1" inch
open.
•
Oil Primary Control: Controls the oil burner ignition. Checks for flame in
the combustion chamber, if no flame is detected within 45 seconds, the oil
primary will shutdown the oil burner. To restart the unit, reset the red button
on the oil primary. Hard lock-out may require holding the reset for 30-45
secs.
•
Oil Pre-Heater Block: Pre-heats the oil and air before entering combustion
chamber.
•
Photo Eye: Senses flame in combustion chamber and signals oil primary when
no flame is present, to shut down or lock-out the system from operating.
•
Air Pressure Gauge: Displays air pressure supplied by onboard air compressor.
(8-14 PSI depending on unit)
•
Air Muffler/Filter: Filters air and quiets the sound generated by the compressor.
•
Pre-Heater Control Circuit Board: Controls temperature of the Oil Pre-Heater
Block and controls safety feature of not allowing burner to energize until
oil has established operating temperature setpoint or shutdown burner if
Pre-Heater Block temperature falls below shutdown temperature setpoint.
MorrHeat - Most Heat In The Industry - Rev 1/31/2019
Page 11
•
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.
•
Air Pressure Adjuster: Adjusts the air pressure going to the pre-heater
block. Should be adjusted between 8 PSI and 14 PSI as indicated on the Air
Pressure Gauge.
•
Oil Filter With Housing: The fuel filter with housing allows an easy spin on/
off feature making it simple when changing filters. Pre-filters the oil prior
to the burner.
•
Suntec/Webster Fuel Pump: Single stage fuel pump will push the waste oil
25 ft. vertical, and 100 ft. horizontal. (Always run fuel lines up to the burner,
never down, or you could create an air pocket in the system - Hard to Bleed)
•
Power Indicator: Indicates when power is present at the burner.
•
Run Indicator: Indicates that the burner is ready for operation after the initial
pre-heat, this process could take 3-4 minutes to pre-heat the system.

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. Consistent fuel supply to the
burner is very important.
4. Check that venting connections are properly installed and connected from the heating unit.
5. While first starting the unit it may take several minutes to get the oil in the pre heater
block up to temperature. Once the oil reaches the desired temperature, oil is then supplied
through the fuel pump assembly and burner assembly. Make sure burner and pump are
turned on.
6. Optimal draft when running the unit is another very important part of the process. Be sure
desired draft is achieved while burner is running. If exhaust fans are present in the building,
it is possible you will need a draft inducer or power vent of some kind (not provided).
7. Thermostat must be off while supplying power to the burner assembly.
8. After the oil in the pre heater block has hit the desired temperature, while the burner is
running, briefly jump the “F” terminals on the oil primary to allow the burner to run during
the fuel pump and priming procedure.
9. After bleeding the fuel pump and flame is established at the burner assembly, remove the
temporary jumpers on the “F” terminals on the oil primary control. This allows the safety
features of the controls to operate properly.
10. Adjust air pressure to 8-14psi if needed.(can vary due to geographic area) (pre set from
manufacturer)
11. Air band on the side of the burner assembly should be closed to 1” open (pre set from
manufacturer) Open too far can cause delayed start or no fire.
13. After properly running and all minor adjustments, if any, are made (pre set from manufacturer)
Check inspection port for bright yellow not orange flame.
14. Flame should be halfway or less down the chamber.
15. Use adjustment screw on the air compressor to achieve proper air (8-14 psi)
16. Contact installer or manufacturer for fuel pump adjustment if needed
DO NOT START HEATER WHEN DELAYED START HAS OCCURRED AND CHAMBER / HEAT
EXCHANGERS ARE HOT, LET UNIT COOL BEFORE ATTEMPTING ANOTHER RESTART &
CHECK FOR ACCESSIVE OIL IN THE CHAMBER PRIOR TO RESTART. TOO MUCH OIL IN THE
CHAMBER UPON RESTART CAN CAUSE A BACKFIRE IN THE COMBUSTION CHAMBER. IF
TOO MUCH OIL IS PRESENT, IT IS RECOMMENDED TO CLEAN OR WIPE UP AS MUCH AS
POSSIBLE BEFORE A RESTART TO AVOID THIS FROM HAPPENING.

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.
Make sure the unit is clean prior to every heating season
HIGHLY RECOMMENDED TO TURN POWER OFF OR UNPLUG THE BURNER UNIT WHEN
CONDUCTING CLEANING AND MAINTENANCE
Monthly:
• Check the ash build up periodically for optimal performance
• Remove all ash when cleaning the combustion chamber and heat exchangers. The viscosity
and oil’s being burnt, cleanliness of the oil and run time play a factor when determining a
maintenance schedule. Every end user will have a little different schedule with all factors
considered for every location and application.
• Check or change oil filter
• Check or change air filters
• Clean flame cone if needed
Twice Per Season:
• Clean or change fuel pump filter. Fuel pump cover comes off to access filter, gasket inside
may also need to be replaced.
• Inspect, adjust or replace electrodes if needed (See part description for desired setting)
• Drain excess water and sludge from fuel storage tank(s)
Once Per Season:
• Remove ash build up within the vent pipe
• Replace nozzle if needed (will erode over time). When replacing make sure the nozzle sticks
slightly past the end cone (1/4” past inside radius of flame cone) to insure no buildup of oil
occurs at the nozzle and flame cone.
• Check the vanes and carbon plates for any chips, cracks or wear within the onboard air
compressor, replace vanes and carbon plates if needed.
The cleaner the unit, the better it performs and longer it lasts!
