Description

The NordicStove Toby Oil Controller with Thermostat, part number NROIL68T, is a mechanical oil flow control unit paired with a non-electric thermostatic control device designed for use with the NordicStove 68 series oil-fired room heater.

The Toby DVR5 oil controller regulates fuel delivery to the vaporizing burner through a variable-position dosage slot on a metering fuel tube, providing continuously adjustable flame output between the calibrated minimum flow rate of 2.0 and maximum flow rate of 7.0 for the 68 series heater. The integrated thermostat allows the oil controller to automatically modulate between low and high burn settings in response to room temperature without requiring electrical power or batteries.

The thermostat component consists of a fluid-filled sensing bulb, a coiled connecting tube, an adjustment knob, and an actuation lever. As the sensing bulb detects ambient temperature changes, the fluid inside expands or contracts, causing the actuation lever to travel up or down over the thermostat fuel metering pin on the oil controller, modulating the fuel flow rate to maintain the selected room temperature.

The connecting tube can be gently uncoiled to allow the sensing bulb to be positioned on the wall near the stove at the appropriate height and distance for accurate room temperature sensing. The oil controller also incorporates a flooded-bowl safety reset lever and a fuel filter screen to prevent foreign matter from entering the regulator. The unit is calibrated for use with Number 1 grade heating oil and is compatible with Number 2 heating oil, with some adjustment to burn settings.

What's Included: One NordicStove Toby DVR5 oil controller calibrated for the 68 series heater with minimum flow rate 2.0 and maximum flow rate 7.0, paired with a non-electric thermostat assembly consisting of a fluid-filled sensing bulb, coiled connecting tube, adjustment knob, and actuation lever.

Installation Limits: This oil controller and thermostat assembly is calibrated specifically for the NordicStove 68 series heater and is not interchangeable with oil controllers calibrated for other NordicStove series. The thermostat operates without electrical power or batteries. If the oil controller output setting is adjusted, the thermostat must be recalibrated to match the new output range. The stove must be level for proper low-burn operation.

Compatibility: Compatible with NordicStove 68 series freestanding natural draft oil-fired room heaters using the Toby DVR5 oil control system and Number 1 or Number 2 grade fuel oil.

Product FAQ

How does the non-electric thermostat on the NordicStove Toby Oil Controller work?

The thermostat uses a fluid-filled sensing bulb connected via a coiled tube to an actuation lever mounted on the oil controller. As the ambient room temperature rises, the fluid inside the bulb expands, pushing the actuation lever downward over the thermostat fuel metering pin on the oil controller, which reduces fuel flow and lowers the burn rate. When the room cools below the selected temperature, the fluid contracts, the lever rises, and the oil controller allows more fuel to flow, increasing the burn rate. This mechanical process requires no electrical power or batteries to operate.

What do the minimum and maximum flow rate settings of 2.0 and 7.0 mean for the 68 series controller?

The minimum setting of 2.0 and maximum setting of 7.0 represent the calibrated operating range of the Toby DVR5 oil controller as configured for the NordicStove 68 series heater. These values correspond to the low and high fuel flow positions on the controller's dosage slot metering system, which determine the low and high burn output levels of the 68 series burner. The 68 series at maximum setting delivers an input rating that produces a proximal heat output of 6,800 BTU. The controller must not be used on NordicStove models calibrated to different flow rate ranges, as the dosage slot dimensions are series-specific.

Where should the thermostat sensing bulb be positioned for accurate temperature control?

The sensing bulb should be mounted on the wall near the stove at a position that accurately reflects the ambient room temperature being targeted. The coiled connecting tube can be gently uncoiled to extend the bulb away from the oil controller body and place it at the appropriate height and horizontal distance from the stove. The exact mounting height and distance from the stove will vary by installation and may require adjustment during initial use to achieve the desired room temperature response behavior from the thermostat.

What is the flooded-bowl safety reset lever on the Toby DVR5 oil controller?

The flooded-bowl safety reset lever is a safety feature integrated into the Toby DVR5 oil controller that allows the operator to reset the float valve mechanism in the event of a fuel overflow or flooding condition within the oil control bowl. If fuel flooding occurs, the reset lever can be actuated to restore the controller to normal operating condition. This feature provides an important safeguard against uncontrolled fuel delivery to the burner and is part of the Toby DVR5's design for safe, reliable operation in residential heating applications.

Can the NordicStove 68 series Toby Oil Controller be used with Number 2 heating oil?

Yes. The NordicStove 68 series Toby Oil Controller is calibrated for Number 1 grade heating oil but is compatible with Number 2 heating oil. When Number 2 oil is used, heat output values may be slightly lower and the stove may not burn properly at the low range without adjustment. If Number 2 oil is selected as the fuel source, the high burn setting should be adjusted first followed by the low burn setting, and the thermostat should be recalibrated to match the adjusted output range of the controller.

Why must the thermostat be recalibrated when the oil controller output setting is changed?

The thermostat actuation lever is calibrated to modulate between the specific low and high burn positions established by the oil controller's current adjustment settings. When the controller's high or low burn adjustment screws are changed, the fuel flow rates at those positions change accordingly, meaning the thermostat actuation lever now operates across a different fuel delivery range than it was previously set for. Recalibrating the thermostat after any controller adjustment ensures that the thermostat's temperature response behavior continues to match the actual low and high output levels of the adjusted controller.
