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.
