3.8 CBE-EM DUAL ENERGY 
INSTALLATION 
 

In order to obtain a special rate from your 
electric utility for residential use, your GTH boiler 
can be hooked-up to an existing oil heater. 
Contact your electric utility to find out if your 
property is eligible for such rates and how to 
register for them. For installations instructions, 
refer to figure 12, 13 and 14. 
 
The CBE-EM dual-energy control (an available 
option, three-way, motorized valve (1’’ NPT F 
standard) included) is specially designed to 
electric utility standards. The CBE-EM control 
selects the least expensive energy source based 
on outside temperature, user choice or a signal 
from your utility. 
 
The CBE-EM dual-energy control will start up 
the oil burner upon receiving the appropriate 
signal, even if the thermostat in the house is not 
calling for heat. It will shut off when the 
temperature in the boiler reaches its target on 
the Limit Control. It is for this reason that the 
piping requires an anti-gravity valve (flow check 
valve) or motorized zone valves. 
 
A three-way, motorized valve (1’’ NPT F 
standard) will direct the water flow either to the 
oil-fired heater or to your DTH electric boiler, 
depending on the signal received. This way, 
your oil heater will cool down and eliminate any 
energy loss, either through the chimney or by 
way of conduction in the boiler room.
