INSTALLING OPTIONAL WALL
MOUNT SWITCH - GWMS2
1. Connect one terminal of 25 ft. wire for the wall
switch to the TPTH terminal on the valve. Con-
nect remaining wire terminal to the TH terminal
on the valve. Make sure that the wire terminals
are in the positions on the unit as pictured in
Figure 43. If wires are not connected as shown
the switch will not work.
2. Route the 25 ft. wire through openings pro-
vided on the sides of the burner system to a
convenient location to mount your switch.
3. Connect one bare wire end to each of the
terminals of the GWMS2 wall switch.
4. Install the wall switch and cover in the wall.
IMPORTANT
: Do not use any other wire than
that provided with the GWMS2 wall switch kit.
Do not exceed 15 ft. of distance from the valve
connection. Using wire of higher gage or turns
or exceeding the minimum distance will increase
resistance at the control valve causing unreliable
performance of the fireplace controls.
