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. If mounting under the floor the heater should be positioned within the chassis members and close to
the axle to help protect the appliance.
iii. Please note: The heater, ducts and flues will become hot. Please avoid anything directly touching
these.
iv. 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.
v. 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.
vi. In selecting the position of the Space Heater, ensure that the exhaust flue and combustion air inlet
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.
vii. 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.
viii. Only Whale® supplied flue components are permitted to be used. The open end of either flue must
not be positioned within 300mm 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.
Fig. 10 9
Fuel refuelling / breather vent

ix. The combustion air inlet flue can be terminated underneath the vehicle. The open end of it must be
at 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 inlet
flues are terminated in an under-floor box section.
x. The minimum length of the exhaust flue is 0.75m, and maximum length 2m. The minimum length of
the combustion air inlet flue inlet must be 0.75m, and maximum length 2m.
xi. When operating using gas, the combustion air inlet 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 outlet flue
and combustion flue intake).
xii. 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.
xiii. 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.
xiv. The heater must not be used when the vehicle is in motion unless the vehicle in motion flues and
bracket are fitted. The vehicle in motion kit is not standard and is available separately. Please refer to
the vehicle in motion kit instruction for further fitting considerations or contact Whale® Support for
more information.
If installing on the underside of the vehicle floor skip Steps 2 and 3.
Step 2 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 inlet and exhaust flues, then drill holes with a 51mm (2”) minimum diameter hole saw.
Fig. 11
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.
Fig.12

Step 3 Attach heater to the floor
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”), as
per Figs. 12 & 13
Fig.13
Proceed to Step 6
Step 4 Underfloor heater location
For under-floor installation the floor of the vehicle should be manufactured as per the Fig. 14. It is important that
wooden batons are incorporated in the floors construction to allow the screws to secure into.
Fig. 14
Locate the heater in the correct position such that the screws will enter the batons, and attached with 10 screws (No.
8 x 5/8”) provided. Ensure that the mains cable is fed through the rectangular cut out and is not trapped between the
outer cover box and the floor.

Fig. 15
Step 5 Securing the flues
Fig. 16
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 6 Mounting the flues
When mounting the combustion inlet flue and exhaust flue, 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.
12

The combustion air inlet 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 as per diagram, Fig.17.
Fig. 17
Step 7 Connect to gas supply
Fig. 18
13

Fig. 19
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 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.
Please note: The operating pressure for the gas supply should be either 28-30mBar Butane or 30mbar/37mbar
Propane.
Step 8 Fitting Hot Air Ducts
To fit the ducting push it onto the ‘outlet’ nozzle, where it will be gripped by the nozzle.
Fig. 20

Fig. 21
If fitting an under floor heater, fit the air duct into the hot air outlet fitting.
Important: At least one hot air outlet vent is to be permanently open. The hot air duct should not be fed into the
centre branch of a Tee fitting as per Fig. 22.
Fig. 22
Step 9 Fitting Cold Air Supply
The Whale® 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, push it onto the cold air inlet nozzle, where it will be gripped
by the nozzle.
