The high-level switch, when not engaged, is in a closed position. If the temperature in the combustion chamber rises above a safe level, it opens the high-level switch breaking the closed-circuit and shutting down the furnace. It’s easiest to test with the switch removed. Attach the red...
The utility model discloses a combustion control system for a building element fire-resistance test furnace. An inlet of a gas total pipeline is connected with a manual ball valve and then sequentially connected with a gas filter, a high-pressure pressure gauge, a quick cut-off valve, a gas...

Along with the house forced air unit (the furnace), we kept the inside smoke to a minimum. My next door neighbor also suffered from the smoke so when the air was at peak unhealthiness, I quickly cobbled together a portable air filter to help out. It was basically just a wooden frame ...
