Re a d a l l s a fe t y p r e c a u t i o n s a n d fo l l ow P S I
recommendations when using this torch. If you
suspect that a part is damaged or defective, call a
qualified service agency for repair or replacement.
2.
The torch’s gas pressure regulator (with pressure
relief valve) must be protected from adverse weather
conditions (rain, ice, snow) as well as from building
materials (tar, concrete, plaster, etc.) which can affect
safe operation and could result in property damage or
injury.
3.
Check all connections for gas leaks. Gas leak testing
is performed as follows:
-- In the event a gas leak is detected, check the
components involved for cleanliness and
proper application of pipe compound before
further tightening.
-- Fu r t h e r t i g h te n t h e g a s c o n n e c t i o n s a s
necessary to stop the leak.
-- After all connections are checked and any
leaks are stopped, wait at least 5 minutes to
allow gas to dissipate.
-- Light the torch.
-- W i t h t h e to rc h i n o p e r a t i o n , c h e c k a l l
connections, hose connections, fittings and
joints with approved gas leak detectors.
-- If a leak is detected, check the components
involved for cleanliness in the thread areas
and proper application of pipe compound
before further tightening.
-- Tighten the gas connection as necessary to
stop the leak.
-- If necessary, replace the parts or components
involved if the leak cannot be stopped.
-- Ensure all gas leaks have been identified and
repaired before proceeding.
4.
A qualified service agency must check for proper
operating gas pressure upon installation of the torch.
5.
Light according to instructions within owner's manual.
6.
Model 161-D (cast head) torches must have the
proper gas regulator for the application. Use only the
L.B. White regulator originally supplied with the torch.
The regulator supplied with this torch includes a POL
fitting incorporating an excess flow valve. Model 172-
D (steel head) torches include a POL fitting with
excess flow valve for direct connection to the gas
supply without use of a regulator. Regardless of torch
model, the excess flow valve is a safety device which
protects against discharge from the propane gas
supply container if the POL is broken off from the
torch when in operation. If the POL fitting is ever
replaced, it needs to be replaced with an L.B. White
POL fitting. Failure to do so can result in fires,
explosions, loss of property, injury or death.
7.
This torch is configured for use for propane vapor
withdrawal only. Do not use the torch in a propane
liquid withdrawal system or application. If you are in
doubt, contact L.B.White Company.
8.
Take time to understand how to operate and maintain
the torch by using this Owner’s Manual. Make sure
you know how to shut off the gas supply to the torch.
Contact your fuel gas supplier if you have any
questions.
9.
Any defects found in performing any of the service or
maintenance procedures must be eliminated and
defective parts replaced immediately. The torch must
be retested by properly qualified service personnel
before placing it back into use.
10.
Open the gas supply valve slowly to prevent lock up of
the excess flow valve within the POL fitting. If opened
quickly, lock-up may occur, and gas supply will be
blocked. To correct this, close the fuel supply valve
and wait about 1 minute for the flow device to reset
itself.
14.
Propane gas supply containers have left handed
threads. Always use the appropriate wrench to make
a connection to tighten or loosen the P.O.L. fitting at
the container’s gas supply valve.
15.
Always use pipe thread compound that is resistant to
propane and natural gas when making threaded
connections.
16.
The components on the torch that call for hand
operation should work with hand pressure only. If
more force is required, have a qualified gas heater
service agency replace the defective part. Do not
attempt to repair.
