In the unlikely event of leaks in the gas system, or if there is a smell of gas:
- Extinguish all naked flames
- Do not operate any electrical switches
- Turn off all gas appliances
- Open windows and doors for ventilation
- Do not smoke
- Shut off gas connection
Get the system thoroughly checked by a registered gas engineer.
-The space heater shall not be operated in the following situations:
•When refuelling the vehicle, the vehicle towing the caravan, or other appliances
•When the vehicle in which the heater is installed is in motion.
•When the vehicle in which the heater is installed is in a confined space such as a garage
This appliance is not intended for use by persons (including children) with reduced physical, sensory
or mental capabilities, or lack of experience and knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the appliance.
Ensure that a minimum of one hot air outlet vent is permanently open at all times. This should ideally
be the first outlet and not more than approximately 1 metre from the heater.
Any alteration to the appliance, including flue components, use of non-Propex spare
parts/accessories and non-observation of the installation and operation instructions shall lead to
cancellation of the warranty and exclusion of liability claims and results in it becoming illegal to use
the appliance.
Please note that incorrect installation, misuse or use of non original Propex parts may invalidate the
warranty. It also becomes illegal to use the appliance if incorrectly installed, and in some countries
this even makes it illegal to use the vehicle.
When operating using gas, the combustion air flue and outlet opening for the products of combustion
(exhaust flue) shall never be obstructed. They should be checked regularly, and if necessary cleaned
by the user (e.g. in winter, snow shall be removed from the combustion outlet and air intake).
This symbol indicates that this appliance is suitable for use in Leisure Accommodation Vehicles.
This symbol indicates that this appliance is suitable for use in boats when the correct flue
terminal is used.

DIMENSIONS
In vehicle installation
Step 1 Find suitable location for Space Heater Installation
Consider the following points:
i. For weight distribution in caravans aim to position the Space Heater as near to the axle
as possible. You should avoid (where possible) locating at the very rear and preferably
avoid the very front.
ii. Please note: The heater, ducts and flues will become hot. Please avoid anything directly
touching these.
iii. Ensure the position allows access for servicing the Space Heater and that there is a
minimum of 25mm distance around the heater to adjacent walls.
iv. The hot air outlet of the heater is to be fitted to the hot air ducting system. The heater
should be positioned to minimise the amount of ducting required and sharp bends in the
ducting should be avoided.
v. In selecting the position of the Space Heater, ensure that the exhaust flue and
combustion air flues can be installed avoiding all chassis members and gas pipes etc.
that are located underneath the floor. Remove the flue template from the back of the
instruction manual and use this to find a suitable location.
vi. The open end of the exhaust flue must not be fitted at the side of the caravan /
motorhome where an awning may be fitted. It is thus preferable to install the heater on
the opposite side of the caravan / motorhome to avoid routing the exhaust flue to the far
side of the caravan / motorhome.

6
vii. Only Propex supplied flue components are permitted to be used. The open end of either
flue must not be positioned within 500mm of a refuelling point or fuel tank breather outlet
or any ventilator from the fuel system(s). The exhaust flue must not be fitted within
300mm of a ventilator for the living space or an opening part of a window. The open end
of the exhaust flue must be positioned at least 500mm from the open end of the
combustion air flue and be pointing in the same direction. The exhaust flue should be
positioned at the side or end of the caravan / motorhome. The exhaust flue may be
positioned vertically below an opening part of a window if the appliance is fitted with an
automatic shut-off device to prevent operation when the window is open.
viii. The combustion air flue can be terminated underneath the vehicle. The open end of it
must be least 500mm away from the open end of the exhaust flue, and pointing in the
same direction. Take care to ensure that both flues have a slight downward slope from as
close to the heater as possible to prevent any possibility of water traps. Make sure neither
the exhaust nor the combustion air flues are terminated in an under-floor box section.
ix. The minimum length of the exhaust flue is 0.75m, and maximum length 2m. The
combustion air flue length must be 1.00m min and 2.00m max.
x. When operating using gas, the combustion air flue and outlet openings for the products of
combustion (exhaust flue) must never be obstructed. They should be checked regularly,
and if necessary cleaned by the user (e.g. in winter, snow shall be removed from the
combustion flue outlet and combustion air intake).
xi. Where the open end of the exhaust flue terminates, three sides of the under-floor space
are to be kept open and not obstructed, and not contain through floor ventilation
openings.
xii. The heater, its gas supply, ducting and flues are to be inspected in accordance with
national regulations or if these do not exist, the manufacturer’s recommendations,
however, it is advised that this should be done at least every year.
xiii. The heater must not be used when the vehicle is in motion.

7
Cut out holes for exhaust and combustion air flues
Position the template on the floor where the heater is to be mounted. Mark the position of the two
holes for the combustion air and exhaust flues then drill holes with a 51mm (2”) minimum diameter
hole saw.
Push on the ends of the flues with the blue adaptor to the pipes on the underside of the Space Heater
ensuring they are fully pushed on, and secure with supplied hose clips.
Step 3
From inside the vehicle feed the exhaust and combustion air flues through the holes drilled on the
floor. Locate the heater so that the flues are centralised in the holes and attach heater to floor with 4
screws supplied (No. 8 x ¾”)

8
Push on the ends of the flues to the pipes on the underside of the Space Heater ensuring they are
fully pushed on, and secure with supplied hose clips.
When mounting the combustion air and exhaust flues, they should ideally run downwards from the
heater to their open end to allow any condensation to drain out. The open ends should be angled
downwards to prevent rain from entering. Care should be taken to route exhaust flues around chassis
members and avoiding gas pipes and wires. The flues should otherwise be kept as straight as
possible.
Please Note:- The exhaust flue should be positioned at the side or the rear end of the vehicle. The
open end of the combustion air flue must be at least 500mm away from the open end of the exhaust
flue and pointing in the same direction.
The combustion air flue is attached to the underside of the floor with two of the brackets supplied. The
remaining brackets supplied with the flue kit are used to attach the exhaust flue. Clip the bracket
around the flue and use two screws (No.8 x ¾”) to attach each bracket to the floor.

9
Connect to gas supply
The appliance should be installed by a competent person in accordance with the installation
instructions and comply with any relevant regulations in the country where the appliance is installed.
The Space Heater is supplied with a compression nut and olive for 8mm (5/16”) pipe. The supply pipe
should be checked and be free from dirt or other particles before connection to the compression joint
on the space heater. The supply pipe should be routed so that the appliance can be removed for
servicing.
A gas shut off valve should be located in the vicinity of the space heater and all connections should
be kept to a minimum.
It is recommended that a gas pressure test point is be fitted to the inlet of the appliance.
When the gas line is complete all joints should be tested for leaks using leak detection solution –
Never with a naked flame.
The gas pressure should be verified at the pressure test point.
Note: The operating pressure for the gas supply should be either 28-30mBar Butane or
30mbar/37mbar Propane.
Fitting Hot Air Ducts
Place a hose clip over the hot air duct then push on to the hot air outlet nozzle and tighten the hose
clip.
Important:- Ensure that a minimum of one hot air outlet vent is permanently open at all times. This
should ideally be the first outlet and not more than approximately 1 metre from the heater.

10
Fitting Cold Air Supply
The Propex Space Heater must be adequately supplied with cold air. If the heater is installed in a bed
box or another confined space, either vents into the area must be fitted or ducting used to supply the
heater with cold air. If a vent is fitted, it must be no smaller than one designed for use with 60mm
ducting. If ducting is fitted it should supply air from the living space of the vehicle. To fit the ducting,
place a hose clip over the end, then push on to the cold air inlet nozzle then tighten the hose clip.
Mounting of the Propex Control Panel
When mounting the Propex control panel find a suitable convenient and accessible position. For good
temperature control select a position away from draughts and approximately 1.5m above the floor.
Ensure suitable access for wiring loom connection and cable. Note that the cable to connect the
control panel to the space heater is 3.5m long. The minimum depth behind panel for wiring must be
40mm.
When you have chosen the location, drill a pilot hole in the area you expect to retrieve the heater
cable. If the clearance is OK, open the pilot hole out to 20mm. Remove the two blanking plugs from
their transit posts on the rear of the thermostat. Push the connector on the rear of the thermostat
through the hole and fix the thermostat into position using the two screws provided. Once happy with
the installation cover the holes with the blanking plugs. Take the 6 and 3 core loom from the heater
and connect to the plug on the rear of the thermostat ensuring that the latches are mating correctly. If
access to the rear of your panel is limited then pull the cable end from the heater through your
previously drilled hole and make the connections before pushing it back through the hole, you may
find you need to drill a 25mm hole if using this method.
Electrical Connections 12V
Run the red (12v+) and white (12v-) cable to a convenient DC supply (usually at the battery) and
connect using the fuse holder supplied. Check battery is 12v. Refer to data label for heater voltage.
Insert the 5 amp fuse and test. Ensure ALL electrical connections are completed before connecting to
supply.
The space heater and control panel come complete with electrical connectors fitted.
Please note: We recommend that a 5 amp automotive fuse is fitted in the 12v supply.

11
Electrical Connection 230v
The appliance should be installed in accordance with the installation instructions and comply with any
relevant regulations in the country where the appliance is installed. Electrical installation should be
carried out by a suitably qualified electrician. The electrical supply must be connected to a 13 amp
fused spur provided with an all-pole disconnection and the appliance must be earthed.
Please Note: If the supply cable is damaged it must be replaced by the manufacturer or a Propex
Approved Technician.
Warning: The appliance must not be supplied through an external switching device, such as a timer,
or a circuit that is regularly switched. This is to avoid an inadvertent resetting of the thermal cut out.
Ensure the Space Heater is not located immediately below the electrical supply socket.
Completed installation
Please note: After completing the installation, carry out a full function check including gas soundness
to ensure the appliance has been installed and operates correctly. The gas soundness check must be
carried out by an accredited LPG gas engineer and a test certificate issued.
