- Features
- Standards & Approvals
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 |
