SAFETY WARNINGS & GENERAL INFORMATION
The Heatsource HS2000 is intended for use only as a space heater in
caravans, motor caravans, mobile homes/units and boats (see b below).
Installation and servicing of this appliance must only be carried out by persons
registered with the Gas Safety Register (GB), Corgi (NI), or the relevant national
organisation, in accordance with the relevant regulatory and safety
requirements.
Heater installations must comply with the current British standards for
Motorhomes / Caravans and BS 5482 Part 3 for Boats, and must not be
used incorrectly. Heatsource HS2000 is only suitable for boats when
supplied / fitted with the correct marine installation kit.
This heater is not suitable for installation on the outside of the vehicle.
The heater must not be operated when refueling: the vehicle, towing
vehicle, other appliances or when the vehicle is in a confined space, such
as a garage.
The exhaust gas outlet must not be fitted on the entry door nor in any
position where combustion products may enter the interior.
The heater is designed to operate on Propane gas 37mbar or Butane at 28
or 30mbar (I3+and I 3B/P (30)). The HS2000 may also be used on 30mbar

FAULT FINDING
The Heatsource HS2000 is equipped with an electronic diagnostic system which will detect
fault conditions ranging from poor gas or electricity supply to internal heater malfunctions. In
the event of a failure the yellow light on the thermostat or timer control will flash a certain
amount of times, pause, and repeat until switched off. Count the amount of flashes and refer
to the table below.
Manual Overheat Cut-Out.
The HS2000 incorporates an overheat cut-out which has to be reset manually. If the heater reaches an unusually high tem perature during operation the cut-out
will disengage the gas solenoid valve, cutting off the gas supply to the burner. The operation
of this cut-out could be caused by either a restricted hot air outlet or air inlet, or the heater
being switched off by a battery isolating switch depriving it of its purge cycle. To find the cutout, remove the electronics cover on the heater and look for it positioned above the PCB with
2 yellow wires attached to it. Press the small red button between th e terminals, the fault code
is 7 flashes.

Minimum operating voltage is 10v and max operating voltage is
15v (for 12v heaters) when measured at the heater. Check
propane but the heat output will be reduced. A 50mbar Propane model is
also available. Under no circumstances should an adjustable regulator be
used.
Do not allow materials to come in to direct contact with the heater. Under
no circumstances must the re-circulation air inlet be covered or obstructed
at any time.
The Heatsource HS2000 heater has a type C53flue, and has been tested
and passed the relevant sections of the following standards:
EN 50081-1:1992, EN 55014-1:1993, EN 60945: 1997, EN 298(NNA):1995,
EN 55014-2:1997, EN 50165:1997, EN 50082-1:1997, BS EN 624:2000,
BS EN 298:1994
A data label is situated adjacent to the gas inlet.
The gas supply line should be checked regularly for damage or leaks and
tested under pressure with a proprietary leak tester. NEVER TEST FOR
GAS LEAKS WITH NAKED FL AME. If a gas leak is detected or smelt,
turn off gas at the bottle immediately and ventilate the area. Contact a
registered installer (see a) above) to rectify the problem.

Gas Lockouts
Gas lockouts must be cleared by moving the left-hand knob from gas on (flame) position
to off position then back to the on position. The complete sequence of switch movements
must be completed within 2.5 seconds for a lockout to be successfully cleared. If there is
air in the gas line, e.g. after a gas bottle change, the space heater may require several
attempts before it lights.

IMPORTANT: Do not direct the combustion products outlet terminal (exhaust flue)
towards the combustion air inlet terminal.
Page 3
A 0.75 metre length of 22mm flexible stainless steel tubing with a special
end cap is supplied for ducting the products of combustion away to the
edge of the vehicle. The tubes may not be shortened but can be extended
for certain applications
A “P” clip is provided for fixing the end of the pipe to the underside of the
vehicle with t he end cap slightly protruding under the sill or bumper and
pointing towards the rear of the vehicle.
The maximum overall length of the flue and inlet pipe combined can be up
to 2 metres if required. However, the flue pipe should never be shorter than
the combustion air inlet pipe.
A 0.75m length of combustion air pipe is provided, which is also fitted with
an end cap. This should be attached to the heater with the hose clip
provided and pointed in the same direction as the flue pipe.
Note: The combustion air pipe can be terminated underneath the vehicle
making sure the end of it is at least 0.5 metres away from the end of the
exhaust and that they are not pointing directly at each other. Take care to
ensure that both pipes have a slight downward slope to prevent any
possibility of water traps. Make sure that neither the flue or the combustion
air inlet pipe are terminated in an under-floor box section.
WIRING INSTRUCTIONS
f)
The Heatsource HS2000 heater is supplied with 2 wring looms, a 2 core
(red and black) and a 5 core (red, black, orange, white and green), both are
fitted with terminals and housings to plug into the main PCB positioned
under the removable electronics cover on the heater. The connectors on
the PCB are marked CN24 (power) and CN27 (switches) Grommets are
fitted to the looms which should slide into the slots above the air inlet.
Find a suitable location for the thermostat between waist and shoulder
a)
b)

The heater uses an 8mm (5/16”) gas connection but can be fitted with an
adaptor to take ¼” copper pipe if preferred.
The gas supply should be connected with copper gas pipe with an isolating
valve and all connections made with brass compression fittings, fitted with
copper olives.
Both the air inlet and exhaust hoses MUST be sealed with silicone (tape or
beading) to ensure a gas tight seal and must be inspected annually in
accordance with national regulations.
When the gas line is complete all joints should be tested for leaks using
leak detection solution - NEVER WITH A NAKED FLAME.
Gas pressure should be verified where the gas pipe connects to the heater
using a low pressure gauge or “U” tube, any tests or connections should
only be undertaken by a registered person (see item a) on page 2).
NOTE. Net Heat Input: 2.1kw, average consumption 148 g/h.
