Grounding and Shielding
NOTE: Installer must be a trained, experienced flame
safeguard service technician and should be
familiar with the equipment operation and
limitations and be aware of any applicable local
codes and regulations.
1.
Connect a safety ground to the viewing head housing (if
applicable). A ground screw is provided on the exterior
of s70x/s80x viewing head housings for this purpose.
WARNING
The viewing head housing is grounded through
cable/signal processor, so you must ensure that
AC/DC potentials at ground of signal processor
and viewing head are the same, or damage to the
cable or signal processor can result.
2.
The viewing head and all associated cable/conduit must
be at least 12 inches (31 cm) from any source of high
energy or voltage (for example, igniter equipment).
3.
Install a ground wire from the ignition transformer case
to the igniter assembly.
4.
Ensure all igniter wires and cables show no signs of
wear. Replace any igniter cables or wires that are frayed
or cracked.
5.
The viewing head must be electrically isolated from the
burner front.
a. Electrical isolation can be accomplished by
installing an Ultem nipple (R-518-13) or an Ultem
locking coupler adapter (R-518-PT13 or R-518-
PT13L) in conjunction with a locking coupler (R-518-
CL13-HTG) between the viewing head flange and
the burner mount.
b. The purge air line should also be isolated from the
viewing head. This can be accomplished by
