Propex Heatsource HS2000 Installation & Operation Instructions page 4

g) 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.
h) Run the 2 core 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.
OPERATION
Before use: Pay particular attention to the exhaust outlet and combustion air
inlets to check that neither have been blocked or damaged.
a) Check the gas supply is turned on and that the battery voltage is correct.
Minimum operating voltage is 10v and max. operating voltage is 15v (for 12v
heaters) when measured at the heater.
b) Rotate the thermostat temperature dial fully anti-clockwise and put the 3 position
knob to the flame position.
c) Rotate the temperature dial until the fan starts. There will be a pre-purge pause
of approx 20 seconds to allow any un-burnt gas to leave the flue. A green LED
will illuminate after successful flame ignition.
d) If there is air in the line it may take a few attempts for the gas to ignite. See page
7 for gas lockout resetting. If ignition is not satisfactory the red LED will flash,
refer to the trouble shooting guide page 7.
e) Find the desired temperature setting by adjusting the dial on the thermostat. The
heater will then cycle on and off to maintain that temperature.
f) When the set temperature is reached the green light will go out and the heater will
start its post purge cycle.
g) If the 3 position knob is in the fan position the green LED will illuminate and the
fan will blow cold air continuously.
Sequence of operation:
Switch on
Heater motor starts
20 second pre-purge to clear gases from heat exchanger
Gas valve opens
Spark generator operates
Motor speeds up to normal operating speed
Heater switches off when thermostat temperature reached
Post Purge – fan runs on its own for 3 minutes
Temperature drops
Cycle repeated

l) 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.
m) The heater must not be used when the vehicle is in motion unless fitted with the
relevant flue terminal.
n) Observe all warnings.
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 - Shut off gas connection
- Turn off all gas appliances
Get the system thoroughly checked by a registered gas engineer.
Suitable for use on boats when supplied with correct flue terminal.

FITTING THE HEATER
a)
Find a suitable location which allows access to the heater with suitable room for service
and inspection, usually in a bed-box or locker. The Heatsource HS2000 should be
fitted in an area allowing a minimum distance of 25mm from adjacent walls, ceiling or
shelves from the main body of the heater. Check that there are no chassis members
underneath the location of the exhaust and combustion air spigots.
b)
Using the template provided, drill a 3mm pilot hole through the exhaust and
combustion air spigot centres. Examine underneath the vehicle to check that there is
adequate clearance for a 40mm hole saw. Cut away any carpet or matting around the
exhaust and open out the holes to 40mm. Ensure that three sides of the underfloor
space are kept open and are not obstructed.
c)
Loosen the 4 x M4 screws on the base of the heater and slot the mounting brackets
into position, then re-tighten the screws. Mount the heater in position and mark the 4
mounting holes on the floor of the vehicle for screwing the heater down. Remove the
heater and drill 4 x 3.5mm holes in the marked positions, then screw the heater in
place with the 3/4 x No.8 self tapping screws provided.
- Do not smoke
- Open windows and doors for ventilation
