I'm installing a downstairs fireplace: a DESA LGCFTN/44471 firebox in
a DESA C26LT corner mantle/base. It's pretty straightforward, except
for one thing: I can't figure out what the following gizmo is:
It's underneath the firebox, by itself, isolated by a panel from all
the parts above. It's made up of 2 pieces, both copper-colored - a
bullet shaped cylinder about 5" long, half inch thick and a coiled
wire, about the thickness of 15 guage elec wiring. There are two white
plastic clips that are in the panel nearby, which I think are meant to
hold the cylinder, but were not holding it when I unpacked it. The
wire ends at the back of the pilot lighting unit above.
What is this thing? It is not listed in the parts list. It is not
shown in the parts breakdown illustration. It is not described on the
It is not the thermocouple, which is illustrated in the diagram and is
in the pilot light flame.
I don't know what this is. Furthermore, I don't know where to "hang"
it. It just dangles there on the end of the coiled wire. I assume it
goes in the white plastic clips, but I'm not sure. And why is it
there? SInce we're dealing with gas fire here, I don't want to take
any chances of messing things up.
