How To Initiate 2d Stage On The Gas Furnace Youtube This one shows how to initiate the 2d stage of a 2 stage gas furnace without waiting for the delay. In this hvac training video, i show how 2 stage and 3 stage gas furnace valves work, how they are electrically powered, as well as the pressures that they ru.
Bryant 355 Mav Gas Furnace 2d Stage Heat 3 Youtube Ray mullings goes in depth to explain how to check inlet and manifold pressures on a bryant two stage gas furnace. About 1 hour on stage 1 and then 1 hour on stage 2. a 2 stage furnace with that kind of duty cycle when it's in the upper 20s, your load will be less than 60,000 btu even at 0 degrees out (well below your design temp). which would mean you have a grossly oversized furnace, shouldn't have any need for 2nd stage. 1.) your furnace is maintaining temp @ 1st stage 2.) your furnace uses 2nd stage when it needs to bring temp up more than 4 degrees 3.) the whole design purpose of a 2 stage furnace is to save money by maintaining temp with less than 100% resources. 2 stage is for comfort. not for savings because its running in first stage most of the time. How two stage furnaces work. low stage operation: utilizes less fuel and runs longer cycles. provides sufficient heat on milder days, maintaining a consistent temperature. high stage operation: kicks in during colder conditions when more heat is needed. uses more fuel but provides a higher heat output.

Expert answer. start by ensuring the gas valve to the furnace is open. set the thermostat to its lowest setting to prevent the furnace from activating during the lighting process. locate the pilot light assembly and ignition button, usually situated near the furnace's bottom and behind a small access panel. Two stage furnace benefits include two levels of heating output, the first stage running between 70 80% of the furnace’s rated capacity, with the second stage being activated only in necessary conditions. two stage furnaces are generally effective in balancing the temperature swings in a household and lowering energy use.
