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 must avoid (where possible) locating at the very rear and preferably avoid the very front.
ii. If mounting under the floor, the Space Heater must be positioned within the chassis members and
close to the axle to help protect the appliance.
iii. Please note: The Space 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 Space Heater to adjacent walls.
v. The hot air outlet of the Space Heater must be fitted to the hot air ducting system. The Space Heater
must be positioned to minimise the amount of ducting required and sharp bends in the ducting must
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. The Space Heater must be installed 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 must be positioned at the side or end of the caravan / motorhome. The exhaust flue
may only 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 Flue Locating Diagram
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 Space Heater as
possible to prevent any possibility of water traps. Ensure that neither the exhaust nor the combustion
air inlet flues are terminated in an underfloor box section.
x. The minimum length of the exhaust flue is 0.75 metres, and maximum length 2 metres. The minimum
length of the combustion air inlet flue inlet must be 0.75 metres, and maximum length 2 metres.
xi. When operating the Space Heater using gas, the combustion air inlet flue and outlet openings for the
products of combustion (exhaust flue) must never be obstructed. They must be checked regularly,
and if necessary cleaned by the user (e.g. in winter, snow must be removed from the combustion
outlet flue and combustion flue intake).

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 must be supervised to ensure that they do not
play with the appliance.
Ensure that a minimum of one hot air outlet vents is permanently open.
When using gas to operate the Space Heater, the combustion air flue and outlet openings for the products of
combustion (exhaust flue) must never be obstructed. They must be checked regularly and if necessary cleaned by
the user (e.g. snow or fallen leaves must be removed from the combustion outlet and air intake).
Where the open end of the exhaust flue terminates, three sides of the underfloor space must be kept open and not
obstructed, and must not contain through-floor ventilation openings.
The Space Heater, its gas supply and flues for the products of combustion must be inspected in accordance with
national regulations or if these do not exist, the Space Heater manufacturer’s recommendations. Whale advises that
this must be carried out at least annually.
The Whale® Space Heater must be checked periodically by a Whale® Approved Service Centre / Technician, or
competent person, at least annually. This must be completed according to the practice in the country where it is
used and according to the Whale® instructions. Whale recommends annual testing of gas soundness and
combustion by an accredited LPG gas engineer. The appliance contains ESD sensitive components and therefore
must only be opened by a Whale® Approved Service Centre / Technician (contact Whale® Support).
When using non Whale operating switches provided by the installer or vehicle manufacturer, they are responsible for
providing user instructions and identification of symbols on the control panel.
The inlet vents of the Space Heater must never be blocked and at least one hot air outlet vent must be permanently
open.
OPERATING INSTRUCTIONS
For operation of the Space Heater, a 12V d.c. supply must be connected at all times. To operate the Space Heater’s
electric elements, it must also be connected to a suitable 230V a.c. supply.

If the Space Heater has not been used for some time, dust may have settled inside the Space Heater and the
ducting. Run the Space Heater on the “Fan only” setting (if available) until it clears. The outside of the appliance
should not normally require cleaning. If it does, isolate the electrical supplies and wipe down with a soft, damp cloth
only. Do not use abrasive cleaners. Allow to fully dry before reconnecting the electrical supplies.
The Whale® Space Heater must be checked periodically by a Whale® Approved Service Centre / Technician, or
competent person, at least annually. This must be completed according to the practice in the country where it is used
and according to the Whale® instructions. Whale recommends annual testing of gas soundness and combustion by
