Installation

WARNINGS

Disconnect primary power at the source.

1. In most cases the XTL Valve Kit may be mounted in the
same location as the old one. If not, mount it as close
as possible to the Torch. The valve kit can be mounted
in any convenient position, provided the outlet side
(with two fi ttings) is closer to the torch than the inlet
side (with four fi ttings and a control cable connector).
Dimensions given in the following illustration are to as­sist in locating mounting holes and hardware length.

NOTE

Care must be taken when considering the
mounting location so the exhaust muffler
on top of the assembly is not covered or
blocked.
