![]() Use on an oil stove or furnace to adjust chimney draft for better combustion. Any errors detected during operation are shown on the digital display screen. Check out our 5 or 6, 7 & 8 draft regulator for your petroleum tanks. The system has over-pressure protection, so if excessive pressure builds up between the boiler outlet and the damper, the boiler will be shut down and the damper will open completely to relieve the pressure. This is automatically repeated every seven (7) days, if the actuator has not been operating. The Scandinavian stoves included here incorporate single 'twin-port' air-inlet (draft) controls, which some distributors refer to as primary and secondary. If the damper actuator has been out of commission for seven (7) days, the Bearing Cycle Activation function will open the damper for a short time and then close again. During a period without actuator operation, the control is in alarm mode. ![]() The self-check is repeated every two (2) hours infinitely. Otherwise, it will continue to operate in Operating Priority mode. If so, the appliance(s) will be able to operate without damper operation.Īfter two (2) hours, damper operation is checked and if present, the control will go back to normal operation. Shown here: our yellow arrow points to the draft outlet control on this wood burner. More exhaust hotter fire and less heat transfer into the room Less exhaust slower, smaller fire. During a following call for heat, the Operating Priority function will detect if one or more appliances can be operated safely and with proper draft. Wood stove damper control: adjusts the rate of exhaust of combustion gases and smoke from the woodstove up into the chimney. The integrated proven draft function will shut down the entire system in case of a power failure to the actuator or other mechanical failure. When the last appliance shuts down the damper will stay partly open in post-purge mode for a preset time period. When an appliance shuts down, the damper will close slightly while still maintaining the draft setting. The sequence is repeated every time a new heating appliance calls for heat. Once the draft reaches the draft set-point the damper modulates maintaining a constant draft. After a programmable pre-purge time period, the EBC31 allows the burner to fire (draft must be established within 60 seconds, or the burner will be shut down). Fully open the air control of the wood stove (see product information supplied. A call for heat opens the damper completely. Note: It is important to heat the air in the stovepipe for draft to start. The MODS system is supplied as a complete package with a multi-bladed damper and attached actuator, control(s), pressure sensor, draft probe and over-pressure safety switch.Įach appliance is interlocked with the control. The EBC31 maintains a constant draft for the heating appliances by modulating the position of the damper. The MODS system consists of the MDF, Modulating Damper and the EBC31, Modulating Fan Control along with an OPS, Over Pressure Switch.
