Safety and warning instructions
Introduction
Safety must always be the operator's prime concern. The operator must read and under-
stand this manual and all safety signs on the heater before operating the equipment.
Failure to follow these safety precautions could result in property damage and/or per-
sonal injury or death. This safety summary describes basic safety measures, which apply
to the use and maintenance of the equipment. Further safety measures are described in
other sections throughout this Manual.
Definitions
The following safety alert symbols are used throughout this manual:
Danger Indicates immediate hazards which WILL result in severe personal injury
or death
Warning Indicates hazards or unsafe practices which COULD result in severe per-
sonal injury or death
Caution Indicates hazards or unsafe practices which COULD result in minor per-
sonal injury or equipment damage
Note Indicates special features or operation of the heater
Caution
Follow all rules of safety and safe operation.
Danger
The heater must be earthed while in use to protect the operator from electrical shock.
The heater is supplied with a three-core cable and three-pin earthed plug to fit correctly
earthed sockets. The green (or green/yellow) core in the cable is the earthing wire. Nev-
er connect the green (or green/yellow) wire to a live terminal.
Danger
Always disconnect the power cable from the electrical source when not in use, before
servicing and when changing accessories.
Danger
Use only commercial Diesel (Dieso) or the following NATO, US and civilian designations:
F34 (AVTUR (FSII)) or JP-8 or JET A-1 (b), F35 (AVTUR) or JET A-1, F44 (AVCAT) or JP5 or
TURBO 5, F54 (Dieso), & F58 (KeroB).
Do not use petrol/civgas/gasoline as it may cause a fire and an explosion.
Danger
Observe all standard fuel handling precautions when handling fuel. Avoid spilling fuel
on or near the heater to prevent possible fire. Always stop the heater when changing the
oil lance from one drum/jerry can to another.
Danger
Do not park vehicles, engine driven generators or other equipment which produce toxic
or noxious fumes near the heater. These exhausts could be drawn into the fresh air in-
take of the heater. Avoid operating the heater in a location near objects which could
cause down drafts. Flue gases from the heater stack could be forced downward into the
fresh air intakes.
Warning
Never operate the heater in the shelter to be heated.
The heater is designed for placement in outside (open air) installations using flexible
ducts to connect the heater to the shelter or other enclosed spaces.

Safety and warning instructions, continued
Warning
If, at any time, exhaust fumes or fuel odours can be detected in the space being heated
or ventilated, shut the heater down immediately. If an external source of the fumes can-
not be detected and eliminated the heater combustion chamber must be inspected for
cracks or other defects.
Warning,
electrical hazards
Electrical shock
This heater, and its associated thermostat, operates at 1 × 230 V AC; 50 Hz and conse-
quently there is a risk of electrical shock. Electrical safety precautions are to be strictly
observed. Always disconnect the power supply from the heater unit prior to servicing or
movement. Ensure that regular checks for damage to cables and connectors of both the
electrical supply and the thermostat are carried out; any damage found must be recti-
fied immediately.
Earthing
This heater must be earthed through the 3-core electrical supply cable.
Warning
handling and use
of fuel
Handling of fuel
Fuel is a hazardous substance. Refueling operations must take place in well ventilated
areas, away from sources of ignition. Refer to relevant safety data sheetsand COSHH as-
sessments. Avoid any spillage of fuel. Wherever possible use a drip tray under the heater.
Use of fuel
Before and during use of the heater ensure that all fuel lines/hoses are secure and leak
proof. When connecting the fuel lance to the fuel tank/jerry can or 205 l drum ensure
that it is secured into place in the fuel container and avoid any spillage of fuel on or
near the heater. Stop the heater when changing fuel lances between one fuel drum and
another. When the heater is not in use for any extended period, or during transporta-
tion, ensure that the fuel lance is disconnected from the fuel supply hose and both are
securely stowed in the housing. In such circumstances ensure that the cap of the fuel
container is securely closed. Avoid the build up of water in the bottom of fuel supply
containers.
Risk of fire
Ensure that the burner unit is correctly located into its operational housing and the
locking bar is applied before use. Ensure that any fuel spillages are mopped up and ab-
sorbent material disposed of. Do not let hot heater surfaces come into contact with
items which could readily ignite.

Warning
location and ex-
haust fumes
Location
Never operate the heater in a confined space without adequate ventilation. The heater
should be located externally, and the heat transferred to the shelter by the insulated
flexible ducts. The location of the heater should avoid any possibility of ingesting ex-
haust fumes from other sources such as vehicles, generators or other engines. Any local
downdrafts of air with associated fumes should be avoided.
Fumes
Should at any time personnel in the heated shelter experience fuel odour or fumes the
heater is to be shut down and the source investigated. If the source of the fumes cannot
be detected and eliminated the heater must be changed and the defective heater in-
spected for combustion chamber cracks or other defects responsible for the fumes.
Obstruction of air intakes and ducts
Ensure that all air intakes/ducts, and where fitted, exit ducts are totally free from the
ingress of vermin or debris. Take corrective action to clean/remove obstructions on a
regular basis.
Warning,
physical handling
Lifting and movement
The weight of the heater is shown in the specifications, page 83 and is beyond the safe
handling of one person. Lifting and/or movement should be either undertaken by Me-
chanical Handling Equipment (MHE) or by sufficient numbers of personnel correctly lo-
cated around the heater so as to avoid injury or strain. When lifting the handrails are to
be used.
Caution
If the heater has been stored for an extended period the heater should be run for 5
minutes before connecting the air ducts.
Caution
Do not disconnect the power until the air supply fan has completely stopped.

General description
Purpose and field
applications
The Dantherm portable, duct type, heater model VA-M40 MK II is designed primarily to
supply un-contaminated, heated air to tents and other types of temporary or portable
shelters.
In addition, the heater is suitable for various field applications such as the warming up
of cold soaked equipment, engines, vehicles, aircraft, and other spot or space heating
requirements.
Principle
The heater operates on the indirect fired (clean air) principle thus ensuring that no com-
bustion products or fumes are introduced into the occupied spaces. The forced air sys-
tem provides the most rapid of warm-up capabilities. The units are essentially self-
contained requiring only a source of external electric power.
Performance char-
acteristics
The heater has a maximum heat output of 38 kW with a minimum combustion efficiency
of 85 %. The unit will start at temperatures as low as - 40 °C, and is factory set for oper-
ation to an altitude of 1,500 m Operation at higher altitudes requires minor field ad-
justment of the oil burner. The protective cabinet allows operation in snow or rainy con-
ditions.
Set up and opera-
tion
Set up and operation can be done by a single person. After start up, the heater functions
are automatic, thus permitting the item to be left unattended between periods of refuel-
ing. An optional remote thermostat may be connected to the heater for accurate tem-
perature control within a tent or other enclosure type. The control system also includes
a "vent" only position, which can be used to bring in fresh air, or circulate interior air,
even when heating is not required. The item is designed to be suitable for all standard
transportation modes.
Replacement of
parts
All critical sub-systems and component assemblies are replaceable as modular kits; this
ensures a repair capability at Unit level. No special tools are required for module re-
placement.
Standard configu-
ration
The following is the standard configuration:
Heater VA-M40 MK II
Insulated flue stack
Oil lance for 205 l d6rum
Service manual
2 wheels with rubber tires
