If the burner fails to light, turn the gas off at the
cylinder and allow it to disperse before trying
again.
Once lit, hold down the gas relay button for about
30 seconds.
Only use the heater for the purpose it was
designed for. Improper use may cause expensive
damage and could be dangerous.
If it will not do what you want, assume you have the
wrong equipment for the job. Contact your local HSS
Hire Shop for advice.
Keep the equipment clean. You will find less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.
Handle gas bottles with care. Any protective plug
supplied must be fitted to the valve when not in use.
When not in use, store the equipment somewhere
clean, dry and safe from thieves.
Remember, propane regulators have a reverse
thread- turn them anti-clockwise to tighten, clockwise to
undo. To avoid damaging the thread, always fit the
regulator with its protective cap.
Turn off the gas supply at the cylinder’s valve and wait
for the flame to die.
You can now disconnect the gas regulator ready for
return.

EQUIPMENT CARE
Code 56410/56610

For advice on the safety and suitability of this
equipment contact your local HSS Hire Shop.
Keep children, animals and bystanders away from
the heater. Never leave them alone when the heater is
in use.
Never use this equipment if you are ill, feeling
tired, or under the influence of alcohol or drugs.
This equipment should only be used by a
competent person who has read and understood
these instructions.
Ensure the area is adequately ventilated to prevent
the build-up of toxic fumes and condensation.
Suitable gloves should be worn when
handling this equipment.
Gas cylinders are heavy, never attempt to lift
a cylinder, full or empty, by yourself. Always
get help.
Never use the heater if highly flammable vapours -
petrol or paint thinner fumes for example - are present,
nor in a dusty environment.
Keep combustible materials at a safe distance- at
least 1.5.m (5ft) and Never stand in front of an
industrial heater. If necessary, use a suitable fire- guard.
Never place anything on top of a heater and never
obstruct its air vents. Leave a 300mm (12in) gap all
round to let air circulate.
Keep gas cylinders upright at ALL times, during
use, transporting and when stored. Don’t drop or
knock them as damaged cylinders can be dangerous.
Always switch off the heater when not in use,
leaving it to cool before handling it. Never leave it
switched on and unattended.
Check the condition of the equipment before use.
Gas Safety
Propane gas is highly inflammable. It is also heavier
than air, increasing the risk of explosion in the event of
a leak. So… ALWAYS double -check all gas supply
connections for leaks (smear them with washing -up
liquid and look for bubbles). ALWAYS handle gas
bottles, hoses and connectors with care. ALWAYS store
bottles in a cool, safe place: away from heat and
ignition sources and away from drains and other
places where leaked gas could collect.
NEVER smoke or allow naked lights into the area
while changing gas bottles.
NEVER test for leaks with a naked light!
GENERAL SAFETY If it shows signs of damage or excessive wear, return it to
your local HSS Hire Shop.
Information on COSHH regulations is available from your
local HSS Hire Shop.
Liquid gas can cause severe ‘freeze burns’ so avoid
skin contact by wearing gloves when making
connections.
This cooling effect may also result in the formation
of frost around cylinder connections. Having
satisfied yourself that this is not due to a leak, you
can ignore it or wipe it off with a cloth.
Never apply heat to the cylinder or equipment.
Set the equipment up on firm level ground and
screw the gas regulator onto the propane
cylinder’s valve, turning it anti-clockwise to tighten (it
has a reverse thread) and tighten up with the spanner
provided.
Open the cylinder valve and where applicable, open
the gas control knob, hold a lighted spill to pilot
light and press the gas relay button, the burner
should light.
Safety Cut-out
Most HSS heaters have safety devices which turn
them and their gas supply off if something goes
wrong- say, if they over-heat or the flame gets
blown out. If a cut-out trips, find out why and
correct the problem before turning the heater back
on. If in doubt, contact your local HSS Hire Shop.
