What is a Type B Gas Flue?

What is a Type B Gas Flue?

Bizmatrix have recently started training Type B Gas Flueing. However why exactly is this course important to add to your training and how can it benefit you? Here we discover the numerous benefits and how understanding flueing can greatly increase your skills and experience.

Who is eligible to complete Type B Flueing?

Anyone who has completed a Certificate III in gas fitting or completed the pre-requisite CPCPCM2043 Carry out WHS requirements is eligible to complete the Type B Gas Flue training.

Also, those seeking to achieve the licensing requirements in Canberra ACT for a restricted Type B gas appliance license or other licensing requirements. In some jurisdictions, this unit of competency may form part of accreditation, licensing, legislative, and regulatory or certification requirements.

Note: This unit maybe a license requirement in some areas. It is highly recommended to complete this work if you are accredited for Type B works.

What is the purpose of flueing?

There are four main reasons that flueing is important including:

1. Priming the flue to avoid spillage of products into the room

2. Reducing risk of condensation of water vapor in combustion products

3. Bringing combustible products to outside atmosphere

4. Preventing building structure from fire hazard caused from the heat of flue

Flueing is primarily used to remove excess quantities of gas. As a standard rule, ten cubic metres of air is required to burn one cubic metre of natural gas in an appliance. If combustion products are not removed and replaced with clean, fresh air after time the oxygen in the room becomes depleted leaving excess carbon monoxide. Carbon monoxide is a lethal substance, highlighting the importance of flueing.

How does a flue work?

Flueing is based around one principle, heat, which in the central system to powering and operating a gas flue. Combustion rates rise when the flue becomes hotter.

The hotter the gases – the rates begin to rise, however the cooler the gases the slower their movement. The aim is to extract as much heat from the appliance making the flue gases cooler.

Why is learning how to work on Type B Gas flues important?

As explained in the process of flueing, this is a safety check for the appliance to ensure that no toxic gases/carbon monoxide can be omitted from the appliance. Bizmatrix recommend that all students working on Type B gas appliances complete a flueing course to safely work on these appliances and ensure that all work carried out has been Type B gas flue tested. Due to working on industrial appliances, having this further qualification is so important.

 

Different types of flueing

There are a number of ways to flue a type b gas appliance including:

– Twin wall gas flues vs. Single wall

– Manifold flueing

– Multistory flueing

– Single appliance flue system

– Multiple appliance flue system
