VENTILATION
Even though this heater operates very close to 100 percent combustion
efficiency, it still produces small amounts of carbon monoxide.
Carbon monoxide (CO) is toxic. It can build up in a confined spaces and
failure to provide adequate ventilation can be fatal.
The early symptoms of asphyxiation caused by inadequate ventilation are:
1. Only use in well ventilated areas and make sure that ample ventilation is
present if the heater is being started following a long period without use.
2. Never attach any duct work to the front of the heater.
3. Never cover or impede airflow into or out of the heater.
WE RECOMMEND THE USE OF A CARBON MONOXIDE DETECTOR

DEVIL IRD40B HEATER OVERVIEW
FUNCTIONAL DESCRIPTION
A pump draws fuel from the tank and drives it to the burner under pressure.
Fuel is sprayed and atomised by the nozzle and then ignited by the burner
ignition device. A built-in radial blower provides combustion airflow while air
and fuel forms a combustion mixture. The flames heat up the front plate and
guard, thus releasing heat by radiation.
The burner pre-heater warms up the fuel before start-up and the post-
ventilation function cools down the chamber after each use. No flue or
exhaust pipe is required as all combustion gasses are catalysed during
operation.
The unit can be tilted from 12 to 27oto direct heat at a particular target.

SAFETY FEATURES
The unit is fitted with a temperature limit sensor, which is designed to turn the
heater off if the temperature should rise to an unsafe level. If the sensor is
tripped and the heater is turned off it may require a service. Once the
temperature falls back below the reset temperature, the heater should re-
start.
The heater is fitted with an electrical circuit breaker to protect the internal
components from damage. If the heater should fail to work, this fuse may
require checking by your dealer.
The heater is fitted with a tilt switch designed to turn the unit off immediately if
it should tip over beyond a pre-determined angle.

FILLING THE FUEL TANK
Before re-fuelling, disconnect from
the power supply and allow to cool
down.
Fill the tank with clean, water-free
diesel oil. When refilling, inspect the
mesh filter inside the filler neck for any
trapped contamination and clean
out if necessary.
• When filling the heater, make
sure that the heater is level and
do not overfill. Use a funnel or can with a long filling spout.
Plug the heater into any suitably earthed mains power supply.
NOTE: In cold weather, condensation may develop in the tank if the tank
is empty. Before filling the fuel tank for the first time or after
extended storage periods, vent the fuel tank of any moisture or
condensation.
POSITIONING THE HEATER
The heater must be located on a
hard, level surface to minimise the risk
of accidental tipping over or running
forward. Chock the wheels if there is
any possibility of movement.
Set the heater angle of inclination by
loosening and re-tightening the
positioning knobs on either side to
achieve the required angle of tilt.
This heater should not be used in
habitable areas.
MATERIAL CLEARANCES
It is important that the heater be positioned with at least 3 m clearance at the
front between the heater and any obstruction including walls or other
combustible surfaces. Always position the heater facing the centre of the
room. Never place any objects on, or against the heater.
Any equipment or workshop furniture should be a safe distance away as they
could be adversely affected by heat. When the heater is in use, periodically
monitor any buildup of heat on nearby surfaces.

VENTILATION
The heater must only be installed in a room which is well ventilated. Ensure that
sufficient air is available for combustion via windows and doors, especially if
there will be people staying in the room for any length of time. Constant
occupation is not advised although the heater should be monitored
periodically.
Ventilation is essential to reduce the dangers of oxygen depletion.
HEATER OPERATION WITHOUT PEOPLE IN THE ROOM
Ensure that sufficient air is available via windows and doors for complete
combustion. The heated volume (m3)/ heat output (kW) ratio must be at least
10:1, and personnel should not stay permanently in the heated room.
HEATER OPERATION WITH PEOPLE REMAINING IN THE ROOM
If people are to remain in the room for any length of time, the heated volume
(m3) /heat output (kW) must be at least 30:1. Air circulation must be ensured
through windows and doors or permanent openings near the floor and
ceilings, whose total open area (m2) is at least 0.003 times the total heat
output (kW).
