Field Controls - 6RC Draft Control (Part# 02722701)
About This Product
For proper operation and efficient fuel consumption in oil, gas, and/or coal-fired heating appliances, draft must remain constant. When it is, combustion is more complete, fuels are utilized efficiently, and money is saved. The 6RC Draft Control maintains consistent draft by counteracting the negative forces caused by changes in temperature and barometric pressure, as well as the effects of wind.
