The furnace is equipped for installation in natural gas ap-plications only. A changeover kit may be ordered for LP applications. The SLP98UHV must be installed only as a Direct Vent gas furnace. NOTE − In Direct Vent installations, combustion air is taken from outdoors and flue gases are discharged outdoors. See Venting for high-efficiency gas furnaces - Materials. Due to the condensing nature of a high-efficiency furnace, its venting must be made of a material that is resistant to corrosion. In a great majority of cases, plastic piping is used to vent high-efficiency equipment. It is classified as "Type BH" venting.

The Concentric Vent allows both the intake for combustion air and the exhaust vent to pass through a standard roof or sidewall. This is an alternative to the standard two pipe intake/vent shown in the basic furnace installation instruc-tions. Follow these instructions as well as the basic furnace

High efficiency furnace venting diagram. The H2O in the exhaust mixes with CO2 in the exhaust and creates Carbonic Acid, H2CO3. This forms a corrosive exhaust that will, given some time, eat holes in your metal venting pipes, as seen in the photo above. If you've got metal pipes coming out of your high-efficiency gas furnace, it's only a matter of time until this happens. Learn the important factors of venting high-efficiency furnaces. This video is for the professional HVAC installer. This and other tips are available at http... Venting for High-Efficiency Gas Furnaces - Assembly. Here are some good venting practices. (This is mostly stuff I learned during a training session from IPEX, one of the major manufacturers of plastic piping, with a little of my personal experience and tips.) First of all, venting must be planned in order to be sized properly. A standard efficiency furnace provides 80% annual fuel utilization efficiency (AFUE). In this type of furnace, 20% of the energy produced by natural gas is expelled as exhaust. High efficiency furnaces offer 90% or more AFUE. These days, 95% AFUE is a common rating among new gas-powered furnaces. So a 95% furnace is more efficient than an 80% ...

In comparing the venting of exhaust gases from a high efficiency furnace, boiler or water heater with the venting of exhaust gases from a conventional heating system it will be immediately obvious that the high efficiency equipment exhaust is produced at a low-enough temperature that it is vented through comparably small-diameter plastic piping ...

Fasco model # A242, Fasco Part number (7021-7150). vent pipe, blocking the exhaust flow. In high-efficiency models, the lower temperature of the exhaust can allow moisture (a by-product of combustion) to condense in the flue, especially when outdoor temperatures drop into the 20's or below. High-efficiency (or "condensing") furnaces exhaust the combustion gases and bring in fresh A high-efficiency or "condensing" furnace can significantly reduce energy consumption in a typical home; however, without a quality installation, the furnace may never deliver its expected energy . savings. Energy Star® has found that new furnaces often do not perform to their rated efficiency with

25.2.2020 · Problem: Draft inducer will not start, ignitor will not glow or gas valve will not open. I think my furnace’s draft inducer is having problems? FYI: *You would be surprised how many people go without heat or cooling for hours/days and all the problem they have is the switch on the side of the furnace is not turned on or the blower door is loose after they change a filter!

the furnace space as specified in the "Venting Requirements" section of these instructions. Adequate clearance must be provided around the vent-air intake terminals. Combustion products must be discharged outdoors. Connect this furnace to an approved vent system only, as specified in the "Venting Requirements" section of these instructions.

Your furnace will require a 2 or 3 inch vent pipe depending on your furnace size even though all of the furnaces have a 2 inch opening where the vent pipe connects. Verify that you are using the correct size pipe by checking the tables below. If the diagram shows your furnace requires a 3 inch pipe, then you will need to use a 3 inch

Feb 27, 2018 · I’ve read dozens, maybe hundreds of high-efficiency furnace installation manuals. Every single one of them had instructions for a direct vent and non-direct vent installation. The diagram below from Goodman shows the different venting requirements for non-direct vent and direct vent.

Here are some of the venting types: 1. Natural vent. Also known as Type B, this vent is operating on natural air convection. This structure generally uses the furnace vent pipe through roof because the B venting pipe is designed in a vertical manner. When the vent is withdrawing air from the house, it expels the gas outside through the vent.

Proper installation of a high efficiency gas furnace requires attention to many details and interconnecting systems: heating capacity (sizing), consideration for duct distribution systems, gas piping, vent systems, provision for combustion air, flue gas condensate disposal, electrical

of the vent plus the furnace input and efficiency are factors affecting the temperature of the flue-gases. Higher BTUH furnaces produce higher flue-gas temperatures. On the other hand, the higher the efficiency of a furnace, the lower the flue-gas temperature. Two cases which can cause poor venting are the oversizing of the vent or reducing the ...

How a High-Efficiency Condensing Furnace Differs . While the condensing furnace is different in its design and repair needs, it does have some similarities to a conventional furnace.Like a conventional furnace, it takes in cold air from the house and runs it through an air filter; it moves the air with a circulating fan; and it has a gas burner with electronic ignition (although condensing ...

Proper venting of high-efficiency condensing furnaces is extremely important to the proper operation of the equipment and to the safety of the building's occupants. An improperly vented system may reduce the unit's efficiency or prevent the unit from operating. Leaking combustion products—which may include carbon monoxide—can cause severe
