G- ELECTRIC ELEMENT (MINI-CADDY WOOD / ELECTRIC) 

 
    The WOOD / ELECTRIC combined model is installed with two thermostats: one thermostat controls the electric 
heating, the other one controls the wood heating.  With this system, the electric heating has priority over the wood 
heating.  When the thermostat activates the electric heating, the air inlet closes down (if opened), the blower starts 
and the electric elements are successively activated per block of 3.75 kW. 
 
    When the call for electric heating is satisfied, the wood system will take over if the starting point of the wood 
system is superior to that of the electric system so, in normal bi-energy use, you should set the wood thermostat 2

o

C 

to 3

o

C higher than the electric system thermostat; the bigger the gap, the more the wood heating will contribute to 

the overall heating needs. 
 
    Take note that this furnace is equipped with a four speed blower motor.  Aside from low speed, you may select  
medium-low, medium-high or high speed. 
 
    If the temperature in the electric unit exceeds 200

°

F, the L-200 thermodisc will disengage the elements until has 

cooled down and automatically turn them back on if the thermostat is still calling for heat.  Should the temperature 
keep on increasing and reach 250

°

F, the L-250 thermodisc will disengage the elements and it will have to be 

reactivated manually by pushing the reset button.  Find and fix the cause of overheating before reactivating the unit.
