This insert operates on a millivolt control system.  As such, no 

addition power supply is needed for the insert to operate. The 

pilot assembly contains a Thermopile, that when heated by the 

pilot flame, generates electricity (millivolts, mV=1/1000 of a volt) 

that travels to terminal #1. From this terminal  it  travels through 

a black wire to the Vent Safety Snap Switch. If this switch over-

heats through a flue blockage or vent pipe disconnection it will 

open, stop the flow of mV and shut the insert off. This switch will 

automatically  reset  (close),  when  it  is  cooled  down  to  normal 

operating  temperature.  During  normal  operation,  it  is  closed 

allowing the mV to flow  back to the valve, which opens so gas 

can flow through. 

To check for proper operation, use a multimeter and perform the 

system checks shown in Table 4 (and refer to Figure 19).

Table 

Do not splice any millivolt wires. Refer to Table 3 to determine 

the proper gage of wire for the thermostat or wall switch 

connections. This table refers to the total length of the wire 

(out to  the switch and back). The thermostat must be  a 

millivolt type. A 24-volt furnace thermostat will not work. 

Never hook up household current, 120 Volts, to the millivolt 

system. It is not recommended to hook up any more than 

two switches to the insert (for example a rocker switch and a 

wall thermostat). Additional switches may affect the system 

resistance and increase the chance of the burner not ignit-

ing. Follow the instructions included with the thermostat or 

remote control for wiring.

The thermostat, remote control, and rocker switch will turn 

the burner on and off independently. Be sure to set the rocker 

switch to the “OFF” position when using the thermostat or 

remote control and set the thermostat or remote control to 

the lowest temperature when you wish to use the rocker 

switch only, otherwise one may override the other. If a re-

mote thermostat is to be used with the insert, do not place 

the receiver under the firebox.
