2 Key Product Safety Areas

Warning. Before installation and / or maintenance refer to Fig.2.1, page 9 to familiarize yourself with:

Mains power.

Hot surfaces.

Flamepath types and locations (surface finishes, thread lengths, threadforms and fits on all
flamepaths must remain undamaged to maintain system integrity and Hazardous Area
certification).

Locking screw locations (locking screws must be in the
operational. Use the 3 mm A/F hexagon wrench [supplied]).

2.1 Flamepath Dimensional Requirements

For dimensional checking purposes, Table 2.1 gives the values and tolerance of the spigot-type joints in the
probe's construction – refer to Fig. 2.1, page 9 for flamepath FP
