Field Wiring Connections
Make sure electrical power to the heater is discon-
nected to avoid potential serious injury or damage to
components.
CAUTION: Label all wires prior to disconnection
when servicing controls. Wiring errors can cause im-
proper and dangerous operation. Verify proper
operation after servicing.

Wiring the Thermostat
1. Connect the room thermostat to the terminals
marked THERMOSTAT in the electrical junction
box (shown in Fig. 16). Alternately, any dry contact
closure across these terminals will enable the
XFyre unit to run. Caution should be used to
ensure neither of the terminals becomes connect-
ed to ground.
2. Mount the thermostat on an inside wall as central
as possible to the area being heated, but away
from drafts or heat producing devices, such as tel-
evision sets, that could effect the ability of the
thermostat to measure the room temperature
accurately.
3. If the thermostat is equipped with an anticipator,
and it is connected directly to the XFyre boiler, the
anticipator should be set at .1 amps. If the thermo-
stat is connected to other devices, the anticipator
should be set to match the power requirements of
the device it is connected to. See the instruction
manual for the connected devices for further infor-
mation.
