WARNING: Operating Precautions
This is a kerosene, direct-fired, forced air heater. It’s intended use is primarily temporary heating of buildings under construction, alteration or repair. Direct-Fired means that all of the combustion products enter the heated space. Even though this heater operates very close to 100 percent combustion efficiency, it still produces small amounts of carbon monoxide. Carbon monoxide (called CO) is toxic. CO can build up in a heated space and failure to provide adequate ventilation could result in death. The symptoms of inadequate ventilation are:

headache
dizziness
burning eyes and nose
nausea
dry mouth or sore throat

Be sure to follow advice about ventilation in the Safety Precautions section. Forced Air means that a blower or fan pushes the air through the heater. Proper combustion depends upon this airflow; therefore, the heater must not be revised, modified, or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modified in order to operate the heater. When the heater is to be operated in the presence of other people the user is responsible for properly acquainting those present with the safety precautions instructions, and of hazards involved.
WARNING: Safety Precautions
THIS IS A HEATING APPLIANCE. DO NOT ATTEMPT TO WARM OR COOK FOOD ON THIS HEATER.

Recommended for use with No.1-K kerosene fuel. Factory tested for use with No.2-K kerosene, No.1 or No.2 Diesel, No.1 or No.2 fuel oil, or JP8 Jet A fuel, and these fuels may be used as well. Never use gasoline, biodiesel, oil drained from crankcases, naphtha, paint thinners, alcohol, or any other highly flammable fuels.
Check the heater thoroughly for damage. DO NOT operate a damaged heater.
DO NOT modify the heater or operate a heater that has been modified from its original condition.
Suitable for either outdoor or indoor use where adequate ventilation is provided. Never use in areas normally for habitation. Not for use where exposed to the weather.
Use in well-ventilated areas, provide at least 2 sq. ft. (0.19 sq. m.) of opening near the floor and 2 sq. ft. (0.19 sq. m.) near the ceiling directly to outdoors. Increase air openings as marked for each additional heater.
Always keep combustibles, like paper and wood at least 8 ft. (250 cm) from the heater outlet and 3 ft. (91.4 cm) from the top, sides, and inlet. Locate 10 ft. (3.0 m) from canvas or plastic coverings and secure them to prevent flapping movement.
Caution: Due to the high surface and exhaust temperatures, adults and children must observe clearances to avoid burns or clothing ignition. Do Not Touch. Keep children, clothing, and combustible away.

Follow all WARNINGS and Precautions found in this manual.
Fill the fuel tank with clean kerosene. In extremely cold weather, condensation may develop in the tank and it is recommended that a tablespoon of de-icer be added for each gallon (4 liters) of fuel in the tank. When filling the heater, use at least 2 gallons (8 liters) of fuel. Be sure the heater is level and do not overfill. Use a funnel or can with a long fill spout.
Locate the heater at a safe distance from combustible materials.

IMPORTANT: Before filling the fuel tank the first time or after extended storage periods, drain the fuel
tank of any moisture or condensation.

HEATER STARTUP

Turn the thermostat to the lowest setting and make sure the “On/Off” switch is “Off”.
Plug the heater into a grounded 115V, 60 Hz, 1 Ø outlet.
Start heater by pushing toggle switch to “On” position (light signifies switch is in “On” position.)
Adjust the thermostat to the desired setting. The heater will cycle on/off as heat is required.

In cold weather (below 10 °F [-12.2 °C] ) starting may be improved by holding a finger over the vent hole of the pump adjustment screw cap until the heater starts.
This unit is equipped with an interrupt circuit. The reset is integrated into the “On/Off” switch. If the unit does not start, toggle the switch to “Off”, wait 5 min, and toggle the switch to “On”
EXTENSION CORD REQUIREMENTS: Up to 100’ (30.5 M) use 16 AWG conductor. 101’ – 200’ (30.5 – 61.0 m) use 14 AWG conductor.

HEATER SHUT DOWN
Push “On/Off” switch to “Off” position. For extended shutdown, unplug the heater from the power source. HEATER RESTART AFTER SAFETY SHUTDOWN

Maintenance and Storage

WARNING: To prevent personal injury, unplug the heater from the wall outlet before servicing. For maximum efficiency and trouble-free service, make the following periodic maintenance, cleaning, and inspections.
ADJUSTING PUMP PRESSURE
Due to varying fuel viscosities and normal component wear the pump pressure on this heater may need to be adjusted.

ADJUSTMENT PROCEDURE

Fill fuel tank.
Start heater.
Locate the pressure adjustment screw, located on the back of the power pack assembly and accessible by the handle of the heater.
Remove the rubber cap over the fuel pressure adjustment screw.
Using a flat-bladed screwdriver, turn the pump pressure adjustment screw:
• clockwise to increase pump pressure
• counter-clockwise decrease pump pressure By using the installed pressure gauge (if equipped) you may quantitatively calibrate the pressure. The manufacturer’s recommended pump pressures are in the specifications chart on page 3.
The desired qualitative burner characteristics are that the nose cone in the combustion chamber should be cherry red with no dark spots and the flame should not extend beyond the nose cone.

IMPROPER PRESSURE ADJUSTMENT
Problem:
The heater does not have a strong consistent flame. Heater smokes and spits raw fuel.
The nose cone does not get cherry red.
Adjustment:
Pump pressure is too low. Turn the adjustment screw clockwise to increase pump pressure
Problem:
Flame extends beyond the end of the heater.
Adjustment:
Pump pressure is too high. Turn adjustment screw counterclockwise to decrease pump pressure.

Daily Maintenance Schedule

GENERAL. Make a general visual inspection of the heater for loose or damaged parts. Check nuts and bolts to ensure against looseness caused by vibration or rough handling. Damaged parts should be repaired or replaced before using the heater again. Check heater operation to be sure it is operating normally (See “Servicing” section for a description of normal operation).
2. FILTERS. Dirty air or fuel filters will cause an imbalance in the air-fuel mixture. The best indication that this condition exists is an increase in odors or difficulty getting your heater to ignite. This heater should never be operated without the filters in place. If required, clean filters as described under “500 Hours” and “Annual
Schedules”.

500 Hour Maintenance Schedule

AIR INTAKE FILTER. Remove and wash the filter element with a mild detergent, dry thoroughly and replace. Do not oil the filter element. If your heater is used where there is considerable dust or dirt, clean as often as necessary(approximately every 50 hrs.).
REMOVE DUST. Clean heater twice a season (more often under dusty conditions). Remove accumulated dust from the transformer, burner, motor, and fan blades with compressed air. Wipe area clean with a clean dry cloth. Inspect the area to insure all foreign materials are removed, especially around the burner and combustion area. Safety glasses should be worn when using compressed air.
CAD CELL. Clean the glass portion of the cad cell with a soft dry cloth.
NOZZLE. Accumulation of dirt from fuel and carbon from the compressor vanes will eventually fill up the passages in the nozzle, resulting in a reduction of fuel and airflow. Pressure will gradually increase giving improper fuel-air mixture and excess odor and smoke. If this occurs, replace the fuel nozzle.
FUEL TANK. Clean twice a season (during frequently used periods, clean twice a month). Drain and flush the fuel tank with clean fuel oil. Make sure to dispose of waste fuel properly.

Annual Maintenance Schedule

AIR OUTPUT FILTER. Remove the air output filter and tap the contaminated side gently on a solid object to remove contaminates. Compressed air or liquids should not be used to clean this filter. Reinstall cleaned filter in filter body in the same position as it was when removed. If the filter appears extremely dirty, replace it with a new filter of the same type. When replacing the filter cover, be sure the gasket is firmly in place and the screws in the filter cover are tight to prevent air leaks.
FUEL FILTER. Remove the fuel filter from fuel line and direct compressed air through the filter in the opposite direction of fuel flow. Safety glasses should be worn when using compressed air.
AIR AND FUEL LINES. If the air or fuel lines are removed during cleaning, be sure all connections are tight before operating the unit.

Storage

Store the heater in a dry location free from fumes or dust. At the end of each heating season, clean the heater as described in the MAINTENANCE section. Drain and flush the fuel tank with clean fuel. The manufacturer recommends completely filling the tank with fuel for extended storage to minimize condensation inside the tank. It is recommended to only store kerosene in containers that are marked “KEROSENE”.

FAQ’S

Can you use diesel in Dewalt kerosene heater?

The DXH185KT thermostatically controlled forced air kerosene heater burns at 185,000 BTU/HR and can be used with kerosene diesel, fuel oil or JP-8 fuels.

How long will a gallon of kerosene last in a kerosene heater?

It will go through a full tank of kerosene in about 10 hours. So, a 5 gallon kerosene can will only last you about 25 hours.

Is it OK to use a kerosene heater indoors?

Asphyxiation. Kerosene heaters consume oxygen as they burn. If they are operated in a small room or in an inadequately ventilated area, oxygen in the air could be reduced to a dangerous level.

How does a forced air kerosene heater work?

The wick draws kerosene from the tank via capillary action. Once lit, the wick heats the Kerosene until it turns into a gas (gasification) and this gas is then burnt which heats air via convection or nearby objects via radiation. The burner is designed to properly oxygenate and distribute the flames.

Do kerosene heaters need to be vented?

Provide adequate ventilation
Adequate ventilation is necessary for safe operation of the kerosene heater. Burning kerosene consumes oxygen and produces carbon dioxide, sulfur dioxide, nitrogen dioxide, carbon monoxide and other gases.

What is the best fuel for a DEWALT kerosene heater?

The only fuel approved for DEWALT kerosene heaters is K-1 kerosene. K-1 kerosene is most commonly found at local convenience stores and service stations. Only buy kerosene that is rated K-1. Lesser quality fuels will produce odor and may cause other problems.

How long does it take DEWALT kerosene heater to warm up?

The DEWALT Kerosene Forced-air heater’s wick needs at least 60 minutes to soak up enough fuel to burn properly. It is important to WAIT 60 minutes ANYTIME the heater has completely burnt the fuel tank “dry”.

Why is my kerosene heater not working?

If your kerosene heater won’t light:
Make sure your heater is filled with quality K-2 grade kerosene, and that the wick has been soaked for at least an hour before attempting to light it. When you push the “ignite” button, the igniter should move into position above the wick surface and glow a bright orange.

How do you turn on a Dewalt heater?

Button all the way down that turns on the gas. And you’re going to light it. And you’re going to hold that down for a few seconds about 10 until the entire honeycomb is lit.

How do you reset a kerosene heater?

Drain the fuel tank and remove the wick assembly. Replace the wick and wick assembly and refill the fuel tank with kerosene.
Light the kerosene heater with little kerosene in the fuel tank. Allow it to burn dry until the flame starts to go out. …
Wait one hour, relight the wick with a match and let it burn out again.

How long does it take for a heater to reset?

Either way, restarting a furnace is a relatively simple task that takes no longer than 10 minutes to complete.
