Genuine Enviro replacement dial-a-fire for Enviro EF5 analog controlled pellet stoves. The analog versions of the EF4 and EF5 will have two knobs or dials on the control area with a green light and a rocker switch. Enviro also made the Solus and Evolution models which were digitally controlled versions of the EF5 and did not use this analog timer control.
This dial-a-fire control replaces older versions of the part that had ONLY yellow and gray wires. The gray wires go to the phase control box which adjusts the RPM of the combustion/ exhaust blower relative to the desired heat output. The yellow wires go to the auger timer block which increases or decreases the 'OFF' feed cycle time according to the desired heat level.
In the United States, the red and orange wires are NOT used with 120v power. If you live in a place where 220v power is used for the stove, the red and the orange wires would connect to the respective inputs on the timer boxes, see your specific manual.
This Dial-a-Fire is a potentiometer that serves two purposes. It adjusts the heat output by increasing or decreasing the 'OFF' time of the auger feed timer, EF-036 (yellow wires), EF1, EF2, and EF3 models use part number EF-044, Dial-a-Fire without phase control (no gray wires).
| Voltage | 115V/ 220v |
| OK Low Resistance | 800 K Ohms to 900 K Ohms |
| OK High Resistance | 150 K Ohms to 185 K Ohms |
| Acceptable Range | 150 K Ohms to 900 K Ohms (± 10%) |
| Full CCW Rotation | Open Circuit |
The dial-a-fire has no effect on the fire Make sure all connections to the timer control module are secure. Perform a resistance test to the dial-a-fire potentiometer by placing the two (2) test leads from a multimeter into the leads of the potentiometer. The potentiometer should have a range of 150 KΩ to 900 KΩ (± 10%). Potentiometer Readings: Full counter-clockwise (switched off) = open circuit, overload or infinite resistance Low fire 800 KΩ to 900 KΩ High fire 150 KΩ to 185 KΩ If the range is not close or does not vary then replace the potentiometer.

Read More About Our Shipping Informationwe are installling this part in an EF 4 what do we do with the red and orange wires? the original part just has 2 grey and 2 yellow wires.
The original Dial-a-Fire part, 20-074 that Enviro equipped with your stove was for units powered by 120v, however; this stove was also made and sold in some Candian PRovinces and European Countries where 220v power is used. Most versions of the stove will have 120v so the red and orange wires are not used and can be zip-tied up and out of the way. If you have a 220v unit, there will be additional input on the phase control and timer box for the other wires.
