OPERATION
WARNING! It is the user's responsibility to ensure the safe use of the blow torch.
‰
3.1.
CONNECTING THE TORCH TO THE GAS CYLINDER. THE TORCH SHOULD ONLY BE USED WITH PROPANE GAS and must
be used in conjunction with the pressure regulator supplied. The torch will work with pressures between 1 - 7 Atm. See Table below for
description of power/energy consumption.
3.1.1.
Ensure that the rubber hose for connecting the torch to the regulator/gas cylinder is in good condition.
3.1.2.
For LPT7 the burners connect directly to the torch. For LPT14 select either the short or long extension and connect it to the torch.
Then select the desired burner for the task in hand and attach it to the torch (or extension) ensuring that the joints are properly seated
and fully tightened.
3.1.3.
Attach the regulator to the gas cylinder and connect the torch using the rubber hose ensuring that the hose connections are properly
seated and fully tightened.
3.1.4.
LEAK TESTING Before lighting the torch all connections must be leak tested using a thick soap solution such as washing up liquid or
ideally a proprietary leak detection spray. Close the burner control on the torch. Open the gas cylinder tap and then the regulator.
Spray every joint on the regulator, hose and torch with leak detection fluid and check for leaks. Tighten any joints as necessary and
retest. If any joints still leak turn off the gas, disassemble and investigate. On LPT14 check condition of "O ring" seals. Do not proceed
to lighting the torch until all joints are gas tight.
IGNITION
2.3.
NOTE: Pilot light control. The burners on the LPT7 are fitted with a pilot light control in the form of a brass sleeve on the burner tube
which will slide over the air inlet holes at the base of the burner stem (see fig.2.3.). This has the effect of turning a blue flame to a more
visible yellow flame when only a pilot light is required. (Only the pipe heating burner on the LPT14 has this feature.)
3.1.5.
Ensure that the burner control tap (fig.2.1.) is turned off.
3.1.6.
Open the gas cylinder tap first and then screw the regulator tap downwards to open it.
3.1.7.
Open the control tap (1) a small amount only until the gas can be heard escaping .
3.1.8.
Draw your flame igniter up to the underside of the torch burner opening.
3.1.9.
Once the torch "pilot"has ignited remove and extinguish the source of ignition.
3.2.
USING THE TORCH If the flame is set for a yellow pilot light slide the pilot light sleeve away from the air inlet holes so that the flame
burns blue.
3.2.1.
For increased flame intensity depress the trigger. (fig.2.2.)
3.2.2.
Release the trigger to return the flame to the "pilot" light.
3.2.3.
Flame intensity can be controlled using the burner control tap (fig.2.1.). As the tap is opened up the flame gets larger. As the tap
approaches fully open the trigger is overridden and only comes back into play again when the tap is partly closed.
3.2.4.
Turn the control tap (1) off to extinguish the torch completely, and then turn the gas cylinder tap off.
4. MAINTENANCE
WARNING! Before commencing service or maintenance turn all gas
‰
taps off and disconnect the torch from the gas supply.
NOTE: From time to time the burner nozzle and injector may require
cleaning. Refer to relevant section below.
LPT7 MAINTENANCE
4.1.
4.1.1.
To dismantle the nozzle To dismantle the nozzle and injector from a burner
insert a 4mm hex key into the hexagonal hole to be seen in the base of
each burner stem. Unscrew the nozzle from the stem. Unscrew the injector
from the nozzle using a 7mm socket or spanner. Wash the nozzle and
injector carefully in petrol or similar cleaning fluid. Do not dislodge the filter
gauze to be found in the base of the fine injectors. Blow out the injector with
compressed air from the filter end only. WARNING! DO NOT clean the
injector with a thin steel wire as this may enlarge the hole in the injector
making it unsafe to use and invalidating your warranty. Reassemble
ensuring that the loose connector nut is held in place by the injector/nozzle
assembly.
4.2.
LPT14 MAINTENANCE
The nozzle/injector assemblies are mounted at the base of each burner
head and serve to connect the heads to the torch extensions. Unscrew the nozzle/injector from the burner head using a 13mm
spanner. Unscrew the injector from the nozzle and proceed as above.
