Do flueless gas fires need ventilation?

Flueless fires require an air vent leading from the room where it is located to the outside. Depending on the size of the kW heat input dictates how large the air vent needs to be. Low costs air vents can cause a draft or noise problems but this shouldn’t be a problem when purchasing a good quality air vent.

Do Calor gas heaters cause condensation?

Don’t use your gas cooker to heat your kitchen as it produces moisture when burning gas (you will notice the windows misting up). Never use bottled gas heaters (Calor etc.) as they produce about 8 pints of moisture from an average-sized gas bottle.

Why do you need an air vent for flueless gas fire?

Air Vent. Your gas fire takes oxygen in from your room to burn. To make sure this air supply is replenished, a vent is required, along with a permanent openable window. Usually, your vent should be at least 100cm2 for a room up to 40 cubic metres.

How far from a flueless fire must an air vent be fitted?

The air vent must provide a minimum amount of “fresh air volume”. This is a trickle of fresh air to replace the air that is being used by the fire. The vent positioning is important as it must be installed over 1 metre away from the fire.

How do flueless gas fires work?

How do Flueless Fires Work? Flueless gas fireplaces work by drawing clean air in from your room through a vent in the front of the fireplace. After the combustion process, the gases which are produced are then passed through a catalytic converter, before being released back into your room.

Does a gas fire smell?

Although it is normal for a fireplace to omit a slight odor, it is important to take proper precautions if you think you may smell a potential gas leak. Natural gas itself is odorless, but has an additive that makes it smell like rotten eggs.

Does butane give off moisture?

All Hydrocarbon fuels such as propane, butane, hexane etc contain significant quantities of Hydrogen and Oxygen which when burned in normal atmospheric conditions rich in Hydrogen and oxygen, will combine to produce water vapour.

Do ventless gas heaters create moisture?

Research from the Gas Research Institute indicates that some ventless gas heaters are oversized for the rooms they are intended to heat. This can result in flue gas and water vapor emissions in excess of what the area can exhaust through normal ventilation and exfiltration in a certain period of time.

How does a flueless gas fire system work?

Description. The Flueless Gas Fire Recess System is designed to allow a flueless gas fire to be installed into the wall, in most installations customers have also installed a TV above the fireplace. This is the overall size of the recess plate, the flueless gas fire fits within the recess.

Do you need ventilation for a flueless fire?

Do flueless gas fires need ventilation? Flueless fires require an air vent leading from the room where it is located to the outside. A flueless fire can only be used with other heat sources as well. It is not possible to use as the primary heating supply.

Do you need a Gas Safe engineer for a flueless fire?

As we said above, it’s most important that you get your flueless gas fire fitted by a Gas Safe Engineer – as with any gas appliance, there are numerous checks that need to be carried out to ensure your fire is running safely. There are also a few requirements for your room when you fit a flueless gas fire.

Can a flueless gas fire be tested without a catalytic converter?

In addition to these requirements, your flueless gas fire will also have safety measures that will shut the gas supply off if the clean air supply isn’t sufficient. In fact, flueless fires are first tested without their catalytic converter and are found to be just as clean!
