What vent pipe is required on top of a furnace?
What vent pipe is required on top of a furnace? A gas wall heater or older forced-air furnace generally requires a type "B" double wall metal vent pipe, while a new high-efficiency furnace requires a schedule 40 PVC vent pipe.
Is it bad to cover a furnace vent?
You could mess with the air flow. Just because you cover the vent, it doesn’t mean your HVAC system knows that. It will keep pushing air to those vents, and if they’re closed, you could cause a buildup of air pressure and insufficient airflow which could damage your system. You could damage the heat exchanger.

How does a direct vent fireplace work?
Direct-vent technology describes a gas-burning appliance that uses two pipes - often one smaller pipe within another larger pipe - to both exhaust the flue gases and bring in fresh air for combustion. They are one of the safest, most convenient, and most popular ways of adding a gas fireplace to your home. The area where the fire takes place, often called the combustion chamber or firebox, is sealed with a glass panel and gaskets protected by a safety barrier screen. This allows you to enjoy the view of the fire while preventing fumes from coming into the home or already-heated room air from escaping out the chimney.

What is direct vent?
Direct vent is by far the most common venting method and is the newest form of venting, invented by the founders of Heat & Glo in the 1980s. It remains a popular choice because of its efficiency, safety, flexibility and the fact that it does not require an existing chimney. But how, exactly, does it work? In direct vent fireplaces, ...
What is a direct vent fireplace?
The direct vent fireplace unit is sealed off from the home’s interior with a high-temperature glass panel and protective screen, so any flames or combustion byproducts are completely separated from the air in your home. This illustration shows how a direct vent can be routed from the firebox directly through the wall to the outdoors, and also the optional side and top venting routes.
How does a gas fireplace work?
When the gas fireplace starts up, exhaust passes through the inner pipe to the outdoors, while the outer pipe brings in fresh air for combustion, transmitting it directly to the bottom of the sealed firebox, where it ignites the unit.
Do you need a chimney for direct vent?
Given the venting flexibility, wide range of styles and the fact that a chimney is not required for installation, direct vent appliances are well-suited to just about any type of home and room.
Can a direct vent be routed through the wall?
This illustration shows how a direct vent can be routed from the firebox directly through the wall to the outdoors, and also the optional side and top venting routes. Direct vent gas fireplaces, stoves and inserts come in a broad range of sizes, efficiently producing heat almost anywhere in the home.
What is a cozy wall furnace?
Cozy’s Direct-Vent Wall Furnace mounts on an outside wall and occupies minimal room space. The continuous seam-welded combustion chamber draws air from the outside and exhausts through a concentric vent system, which keeps the interior air warm and fresh. The louvered cabinet design maximizes airflow, providing uniform temperatures from floor to ceiling. A telescoping vent assembly is included and fits a standard 5”- 9” wall thickness, eliminating the need for expensive and difficult-to-install vent pipe systems.#N#A wall-mounted thermostat comes standard, or choose the optional built-in bulb stat kit (BBSK). Both provide precise temperature control, even if the electrical power fails. All controls include a 100% safety pilot and pressure regulator for safe, efficient operation.
Can wall furnaces be interchanged?
Wall furnace components must not be interchanged or mixed to make a complete furnace.
Why are direct vent furnaces safer than natural vents?
They also do not spoil the quality of indoor air unlike the B-vent type, so safety ratings are higher for direct vent furnaces than natural vents.
What is direct venting?
The outer pipe draws air for combustion from outside, and the smaller pipe occupies the inner position and is used to vent the exhaust fumes. Piping can be set horizontally to allow venting through a sidewall, or vertical installation can also be undertaken to allow venting through the roof. Direct vent systems have versatility to their installation that natural vents do not. Also, no chimney is needed regardless of whether horizontal or vertical installation is used. Installation of direct venting is fairly easy, but more costly than the B-vent type.
What is an induced draft fan?
This is also referred to as an induced draft fan. A fan is placed at the end of an exhaust pipe that runs through a sidewall which draws out combustion gases and expels them outside. The fan works in conjunction with the furnace, usually turning on before the furnace starts. Sidewall vent systems are especially great for replacing old chimneys, and it is one of the more affordable options to consider when installing a venting system for your gas furnace. Sidewall power vents also rate highly in efficiency and safety.
How does a B vent work?
Type B vents are a standard design that most modern gas furnaces use. It draws air from within the house for combustion. Gases produced during combustion are very hot and as such, easily rise through the flue. The air is then vented outside through a B-vent pipe which is set vertically to expel combustion air through the roof. Natural vent pipes can be installed fairly easily, and costs are fairly modest, making them a popular choice. However, back-drafting is more common with natural vent pipes than other varieties. The indoor air can easily pull combustion gases back indoors. This detracts from the efficiency of the B-vent piping. The tendency to back-draft also raises questions over furnace safety where such pipes are used. Back-drafting can affect the health of household occupants through inhalation of toxic emissions if it remains a consistent problem.
What is a gas furnace?
For many homes, a gas furnace is the preferred heating device. It has proven to be an efficient and reliable way of meeting household heating needs over the years. The vent pipe, or flue, is a vital component of the furnace that transmits emissions from the combustion process out of the building. This ensures that those in the building are not harmed by toxic gases and other byproducts of combustion. The flue is also a safeguard against fire. If the waste gases come into contact with other combustibles, a fire can easily break out. Below are three types of venting for gas furnaces.
Can natural vents be back draft?
However, back-drafting is more common with natural vent pipes than other varieties. The indoor air can easily pull combustion gases back indoors. This detracts from the efficiency of the B-vent piping. The tendency to back-draft also raises questions over furnace safety where such pipes are used.
What is a direct vent furnace?
A direct-vent wall furnace is a self-contained sealed combustion heating appliance that warms inside air by recirculating it around a sealed chamber, and discharges combustion byproducts outside the home via direct-vent. They are permanently attached to the structure of a building, and are not connected to ductwork.
What is a zonal heater?
Zonal heating: each heater has its own controls, so you can heat individual areas of your home to varying temperatures. Versatile: there are wall-mounted or freestanding models that come in a range of different colours and styles, including models designed to blend into your décor.
Do direct vent furnaces circulate air?
