OPERATION

KEROSENE (1-K) For optimal performance of this heater, it is strongly suggested that 1-K kerosene be used. 1-K

kerosene has been rened to virtually eliminate contaminants, such as sulfur, which can cause a rotten egg odor

during the operation of the heater. Be advised that these fuels do not burn as clean as 1-K kerosene, and care

should be taken to provide more fresh air ventilation to accommodate any added contaminants that may be

added to the heated space. NOTE: Kerosene should only be stored in a blue container that is clearly marked

“kerosene”. Never store kerosene in a red container. Red is associated with gasoline.

• NEVER store kerosene in the living space. Kerosene should be stored in a well ventilated area outside the

living area.

• NEVER use fuel such as gasoline, benzene, alcohol, white gas, camp stove fuel, paint thinners, or other oil

compounds in this heater (THESE ARE VOLATILE FUELS THAT CAN CAUSE A FIRE OR EXPLOSION).

• NEVER store kerosene in direct sunlight or near a source of heat.

• NEVER use kerosene that has been stored from one season to the next. Kerosene deteriorates over time. OLD

KEROSENE WILL NOT BURN PROPERLY IN THIS HEATER.

• Use 1-K kerosene in this heater. #1 fuel is a suitable substitute.

OVERVIEW OF HEATER DESIGN

Fuel System: This heater is equipped with an electric air pump that forces air through the air line connected to

the fuel intake, and then through a nozzle in the burner head. When air passes in front of the fuel intake, it causes

fuel to rise from the tank and into the burner nozzle. This fuel and air mixture is then sprayed into the combustion

chamber in a ne mist.

IGNITION

The electronic igniter sends voltage to a specially designed spark plug. The spark plug ignites the fuel and

air mixture described. The Air System: The heavy duty motor turns a fan that forces air into and around the

combustion chamber. Here, the air is heated and then forced out the front of the heater.

THE SAFETY SYSTEM

Temperature Limit Control: This heater is equipped with a Temperature Limit Control designed to turn the heater

off should the internal temperature rise to an unsafe level. If this device activates and turns your heater off, it may

require service. Once the temperature falls below the reset temperature, you will be able to start your heater.

ELECTRICAL SYSTEM PROTECTION

This heater’s electrical system is protected by a fuse mounted to the PCB Assembly that protects it and other

electrical components from damage. If your heater fails to operate, check this fuse rst and replace as needed.

Refer to specication chart.

FLAME-OUT SENSOR

Utilizes a photocell to monitor the ame in

burn chamber during normal operation. It

will cause the heater to shut off should the

burner ame extinguish.

FUELING YOUR HEATER

Never ll the heater fuel tank in the living

space: ll the tank outdoors. Do not overll

your heater and be sure heater is level.

IMPORTANT: REGARDING FIRST IGNITION

OF HEATER. The rst time you light the

heater, it should be done OUTDOORS.

This allows the oils, etc., used in

manufacturing heater to be burned

off outside.

VENTILATION

Provide a fresh air opening of at least three (3) square feet (2,800 sq. cm) for

each 120,000 btu/hr. rating. Provide extra fresh air if more heaters are being

used.

Example: A NM-175K heater requires one of the following:

1. A two-car garage door raised six inches (15.24 cm).

2. A single-car garage door raised nine inches (22.86 cm).

3. Two, thirty inch (76.20 cm) windows raised fteen inches (38.1 cm).

TO START HEATER

1. Fill fuel tank with kerosene or No. 1 fuel oil.

2. Attach fuel cap.

3. Plug power cord into three prong, grounded extension cord. Extension

cord must be at least six feet long.

Extension Cord Wire Size Requirements:

• 6 to 10 feet (1.8 to 3 meters) long, use 18 AWG conductor.

• 11 to 100 feet (3.4 to 30.53 meters) long, use 16 AWG conductor.

• 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.

4. Turn THERMOSTAT CONTROL KNOB to desired setting and push power

switch to “ON” position. Power indicator lamp will light and heater will

start.

• If heater does not start, the thermostat setting may be too low.

• Turn THERMOSTAT CONTROL KNOB to higher position to start heater.

If heater still does not start, turn power switch to OFF and then to ON

position.

• NOTE: The major electrical components of this heater are protected by a

safety fuse mounted to the PCB board. If your heater fails to start, check

this fuse rst and replace as necessary. You should also check your power

source to insure that proper voltage and frequency are being supplied

to the heater.

TO SHUT DOWN HEATER

Turn power switch to “OFF” and unplug power cord.

TO RESTART HEATER

1. Wait 10 seconds after stopping heater.

2. Repeat steps under, “TO START HEATER.”

ELECTRICAL OUTLET

• Shock Hazard

• Never plug in an appliance with more than a

5amp rating into this outlet.

• Always keep outlet covered when not in use.

120V 30amp max(non fused).

IMPORTANT: Reinstall plug fully into hole in tank;

otherwise it will not seal completely.

• Make sure storage place is free of dust and

corrosive fumes.

• Store the heater in the original box with the

original packing material and keep USER’S

MANUAL with heater.

The room temperature display will indicate the following:

* When the temperature is less than 0° F, the display says “LO”

* When the temperature is more than 99° F, the display says “HI”

* Between 0° F and 99° F the display shows the actual room temperature
