General Information
The DXRH012E is safe for indoor use in small recreational enclosures having means
for providing combustion air and ventilation, such as enclosed porches, cabins, shing
huts, trailers, tent trailers, tents, truck caps and vans. It may be used for emergency
indoor heating when connected disposable 465g propane (G31) OR 450g Butane/
Propane mixture (G30+G31) cartridge and for indoor use in commercial enclosures,
provided that there is sufcient air for combustion and ventilation (specied in OPERATING
PRECAUTIONS page 5).
NOTE: This heater can be used outdoors, but may experience nuisance shutoffs in certain
wind conditions.
• A DEWALT battery is necessary only for Fan, USB Power Outlets, and Light operation.
• A Propane gas supply is necessary only for Heating operation.
• When the heater is cold or at room temperature, it will take a few minutes for the burner
tile to turn bright orange. This is normal and the heater is working properly. If burner tile
is visibly aming, turn heater off and call a qualied service technician.
• When the unit is lit, there should be about a quarter inch (.635 cm) border around the
tile that will not turn bright orange. This is normal.
• When operating the heater for the rst time, the top area of the reector may discolor.
This is also normal and is no reason for concern.
• The protective grill on the front of this heater is coated with a special high-temperature
resistant paint. When the heater is used for the rst time, the grill may give off noticeable
smoke or fumes. This is normal and will not occur during subsequent uses. The fumes
are not harmful.
• When operating the heater at altitudes over 2.13km above sea level, the unit may not
burn as bright as in lower altitudes. This is normal. At higher altitudes the heater may
shut off. If this happens provide fresh air, wait 5 minutes, and then re-light. Due to local
atmospheric conditions heater may not re-light.
• When moving heater when lit or bumping heater setting it down, the tip over switch may
shut off heater. If this happens, relight.
• Due to natural operation of small cartridges, condensation may build up on cartridge
and drip on surface under heater. Sometimes this condensation may freeze due to the
extreme cold caused when propane (G31) vaporizes. This is normal and no reason for
alarm.
• Operating time will vary depending on the heater setting and the supply cartridge size.
Up to 1.5 to 3.5 hours on a 450G 70/30 Butane/Propane mixture (G30+G31) cartridge.
Due to the properties of Propane gas (G31), run times can be signicantly reduced
when operating continuously at temperatures below -6.6 C.
WARNING: If the information in this manual is not followed
exactly, a re or explosion may result causing injury or loss of life.

WARNING
Asphyxiation Hazard
•Do not use in unventilated areas
•The ow of combustion and ventilation air must not be obstructed
•Proper ventilation air must be provided to support the combustion air
requirements of the heater being used.
•Refer to the specication section of the heater’s manual, heater
dataplate, or contact the factory to determine combustion air ventilation
requirements of the heater.
•Lack of proper ventilation air will lead to improper combustion
•Improper combustion can lead to carbon monoxide poisoning leading
to serious injury or death. Symptoms of carbon monoxide poisoning can
include headaches, dizziness and difculty in breathing.
Fuel Gas Odour
Propane gas(G31) and butane/propane mixture (G30+G31) gases have man-made
odourants added specically for detection of fuel gas leaks. If a gas leak occurs
you should be able to smell the fuel gas. Since Propane (G31) is heavier than air
you should smell for the gas odour low to the oor. ANY GAS Odour IS YOUR
SIGNAL TO GO INTO IMMEDIATE ACTION!
• Do not take any action that could ignite the fuel gas.
• Do not operate any electrical switches.
• Do not pull any power supply or extension cords.
• Do not light matches or any other source of ame.
• Do not use your telephone.
• Get everyone out of the building and away from the area immediately. Close all propane
gas (G31) tank or cylinder fuel supply valves, or the main fuel supply valve located at the
meter if you use natural gas.
• Propane gas (G31) is heavier than air and may settle in low areas. When you have
reason to suspect a propane leak, keep out of all low areas.
• Use a telephone remote from the area of the leak and call your fuel gas supplier and
your re department. Do not re-enter the building or area.
• Stay out of the building and away from the area until declared safe by the reghters
and your fuel gas supplier.
• FINALLY, let the fuel gas service person and the reghters check for escaped gas.
Have them air out the building and area before you return. Properly trained service
people must repair any leaks, check for further leakages, and then relight the appliance
for you.
Odour Fading - No Odour Detected
• Some people cannot smell well. Some people cannot smell the odour of the man-
made chemical added to propane gas (G31). You must determine if you can smell the
odourant in these fuel gases.
• Learn to recognize the odour of propane gas (G31).
• Smoking can decrease your ability to smell. Being around an odour for a period of time
can affect your sensitivity to that particular odour. Odours present in animal connement
buildings can mask fuel gas odour.
• The odourant in propane gas (G31) is colorless and the intensity of its odour
can fade under some circumstances. If there is an underground leak, the movement
of gas through the soil can lter the odourant.
• Propane gas (G31) odour may differ in intensity at different levels. Since Propane gas
(G31) is heavier than air, there may be more odour at lower levels.
• Always be sensitive to the slightest gas odour. If you continue to detect any gas
odour, no matter how small, treat it as a serious leak. Immediately go into action as
discussed previously.
ATTENTION - Critical Points to Remember!
• Propane gas (G31) or Butane/Propane mixture (G30+G31) has a distinctive odour.
Learn to recognize these odours. (Reference Fuel Gas Odour and Odour Fading
sections on this same page)
• Even if you are not properly trained in the service and repair of the heater, ALWAYS be
consciously aware of the odours of propane gas(G31) and natural gas.
• If you have not been properly trained in repair and service of propane gas(G31) or
Butane/Propane mixture(G30+G31) then do not attempt to light heater, perform service
or repairs, or make any adjustments to the heater on the propane (G31) or Butane/
Propane mixture(G30+G31) gas fuel system.
• A periodic sniff test around the heater or at the heater’s joints; i.e. hose, connections,
etc., is a good safety practice under any conditions. If you smell even a small amount of
gas, CONTACT YOUR FUEL GAS SUPPLIER IMMEDIATELY. DO NOT WAIT!

Status Light Diagnostics: Steady On/Off Blinking
If the Status Light is blinking on and off steadily this is an indication that the DEWALT battery
is low on charge. See Battery Charging Precautions and Instructions, starting on page 9.
The battery must be removed from the heater in order to charge.
Status Light Diagnostics: Double Flash
(2 Blinks, 1 Pause)
If the Status Light is “Double Flashing” (repetition of 2 rapid blinks followed by a pause) this
is an indication that the battery is outside of its operating temperature range.
Maintenance
Always keep the heater area clear and free from combustible materials, gasoline and other
ammable vapors and liquids.
Keep the vent areas (slots in the bottoms and the top at the front and rear of heater) clear
at all times.
Visually inspect the pilot ame and burner periodically during use. The pilot ame should be
blue in color (not yellow) and will extend beyond the thermocouple. The ame will surround
the thermocouple just below the tip, see Figure 8.
A slight yellow ame may occur where the pilot ame and main burner ame meet. The
burner should be bright orange (with a slight blue color around the border, a red-orange
haze that is visible on the ceramic tile is acceptable) and without a noticeable ame. A blue
ame that rolls out at the top of the ceramic tile indicates an accumulation of dust, lint or
spider webs inside the casing assembly and main burner assembly. If the pilot is yellow or
the burner has a noticeable ame, cleaning may be required. Use the following procedure
to inspect the casing assembly and main burner assembly. It is necessary to periodically
check the burner orice and burner venturi tube to make sure they are clear of insects/
nests or spider webs that may accumulate over time. A clogged tube can lead to a re.
Electronic Operation
When a charged DEWALT battery is inserted into the battery
dock, Figure 7, the heater may activate the following electronic
features. The battery inserts into the battery dock upright, with
contacts facing the roof of the dock. These Electronic features
may be used individually or simultaneously. When any of them are
in use the status light, Figure 8, will illuminate with a steady green
glow to visually signal that an electronic feature is active. If the
status light is blinking see the diagnostics section below.
Lights
Toggling the Light control button on the back of the heater
activates/deactivates the lights in the handle bar. The Lights
operate with any orientation of the heater and handle.
Fan
Toggling the Fan control button on the back of the heater
activates/deactivates the fan. Using the fan while the heater is
active enhances the heaters convective heating ability. Using the
fan while the heater is inactive will make the heater into a fan,
meaning that you may enjoy the DXRH012E no matter the season!
USB Power Outlets
Inside the USB Compartment which houses the pulse igniter are
also 3 USB Power Outlets, a power button, and a status light.
Toggling the power button will activate/deactivate the USB Power
Outlets with 5 Volts of DC current at 2 amps rating, signaled by
illumination of the status light. The USB Power Outlets facilitate
the charging or powering of up to three USB devices. NOTICE:
The USB power should be shut off when not in use. Failure to do
so may cause battery to drain.
