Price/Availability Accessible On Login
- A double-acting control for gas-fired furnaces and boilers is widely used for conversion burner installations, gas draft-induced appliance operation with mechanical draft inducers, or sidewall power venters
- It is also recommended for use on gas atmospheric appliances where a draft hood cannot be installed, and can improve combustion stability and draft on many gas atmospheric installations with venting problems
- The MG-1 provides precise, accurate control of drafts st levels higher than permitted by a standard draft diverter, which is a frequent requirement with gas
- Because it is double-acting, it opens out to relieve positive vent system pressures as low as 0.01 in
- Draft adjustments using weights are simple and accurate from 0.01 to 0.1 in
- Control size 4
- 12.6 sq-in nominal capacity
- 3 to 4 in recommended pipe diameter
- 9-1/2 to 12-1/2 in recommended pipe circumference
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. Field Draft Controls maintain consistent draft by counteracting the negative forces caused by changes in temperature and barometric pressure, as well as the effects of wind.
