WARNING: Installation must
be done by a qualified installer
familiar with low voltage wiring
procedures.

attached to the underside of the burner
system assembly.
2. Disconnect from the valve the wires
running from the ON/OFF switch.
WARNING: Do not connect
this thermostat to a power
source. Electrical shock and/or
fire hazard will occur.
3. Connect one terminal of the wire for the
wall thermostat to the THTP terminal
on the valve. Connect 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 44. If wires are not connected as
shown the thermostat will not work.
4. Route the wire to a convenient location
to mount your thermostat (no outside
wall).
IMPORTANT:
The wire must
not exceed 25 feet in length.
The thermostat should be mounted 54"
above the floor in a location where
there is good air circulation. Avoid
heat sources such as lamps, direct sun-
light, fireplace, or heat and air condi-
tioning ducts.
