SITE REQUIREMENTS

1.FLUE OR CHIMNEY

1.1The flue or chimney system must be in good condition.

It must be inspected by a competent person and passed for use with the appliance before installation.

Products of combustion entering the room can cause serious health risks.

1.2The following must be checked:

—The construction of the masonry chimneys, flue block chimneys and connecting flue pipe system must meet the requirements of the Building Regulations†.

—The minimum height of the flue or chimney must

be 4.5m from the hearth to the top of the flue, with no horizontal sections and a maximum of 4 bends. Bends must have angles of less than 45 degrees from

the vertical.

—Make provision to remove the appliance without the need to dismantle the chimney.

—Any existing flue must be confirmed as suitable for the new intended use as defined in the Building Regulations†.

—The flue or chimney systems must be inspected and swept to confirm the system is structurally sound and free from obstructions**.

—If the chimney is believed to have previously served an open fire it must be swept a second time within a month of regular use after installation to clear any soot falls that may have occurred due to difference in combustion levels.

—The flue exit from the building must comply with local building control rules†.

—Do not connect or share the flue or chimney system with another heating appliance.

1.3Do not connect to systems containing large voids or spaces over 230mm square.

1.4Suitable access must be provided to enable the collection and removal of debris.

1.5The flue must be swept and inspected when the appliance is installed.

1.6The flue draught must be checked with all windows and doors closed and any extraction fans in this, or adjoining rooms, running at maximum speed (see next section for additional ventilation requirements).

Max. Draught = 2.0mm Wg Min. Draught = 1.0mm Wg

In the U.K:

*The design of the flue and chimney systems and products used should meet the requirements of ADJ along with any other relevant, National or European standards that may apply. Products should be specified with regard to the type of appliance, position within the building, fuels to be used and appliance operating temperatures.

**This should be done by a HETAS Approved Chimney Sweep (UK only) see page 26 / INFO registered (Republic of Ireland only) who will issue you with a certificate.

† Building Regulations Document J

Flue Plate:

Where a hearth, fireplace, flue or chimney is provided or extended (including cases where a flue is provided as part of refurbishment work), information essential to the correct appliance and use of these should be permanently posted in the building, to meet Requirement J4 of the Building Regulations (England and Wales), F3.12 (Scotland).

Additional:

A new factory made system that complies to the latest edition of EN 1856; Part 1 can be used providing installation is to the requirements of:

i)the latest edition of BS EN 15287 Parts 1 -4

ii)the manufacturer's instructions

iii)Building Regulations.

YMMB specifications

Yeoman YMMB, short for Yeoman Yet Another Model Builder, is an advanced tool in the realm of web development, particularly known for its capabilities in scaffolding projects and automating repetitive tasks. It serves as a robust generator framework, streamlined to enhance developer productivity by allowing them to focus on coding rather than setting up boilerplate code. Yeoman YMMB is designed for building modern web applications and provides a seamless workflow that integrates various technologies and development practices.

One of the main features of Yeoman YMMB is its powerful scaffolding ability. Developers can easily create a new project structure with just a few commands, generating the essential files and directories needed to kickstart a web application. This feature not only saves time but also ensures that developers adhere to best practices and standards in web development. The intelligent generators available with Yeoman YMMB can create everything from single-page applications to entire web ecosystems.

Yeoman YMMB leverages several modern web technologies that have become industry standards. For instance, it supports popular front-end frameworks like React, Angular, and Vue.js, making it a versatile choice for developers working on diverse projects. Additionally, it comes with built-in support for various CSS preprocessors such as Sass and Less, enhancing the styling process and allowing for more maintainable stylesheets.

Another characteristic of Yeoman YMMB is its emphasis on modularity. The generator ecosystem enables developers to create and share custom generators that can be tailored to specific project requirements. This feature fosters a collaborative environment, as developers can build upon each other’s work, thereby speeding up the development process.

In terms of configuration, Yeoman YMMB offers a flexible setup, allowing developers to integrate with task runners like Gulp and Grunt. This integration enables automation of tasks such as minification, linting, and testing, streamlining the development workflow. With these automation tools, developers can focus more on writing code and less on managing the build process.

Moreover, Yeoman YMMB is community-driven, meaning it benefits from continuous updates and improvements based on user contributions. The active community provides extensive documentation and a plethora of plugins, each designed to enhance functionality and features. Through this collaboration, Yeoman YMMB remains relevant and up-to-date with the latest trends in web development.

In summary, Yeoman YMMB is an essential tool for web developers who seek efficiency and modernization in their workflow. Its scaffolding capabilities, support for modern technologies, modularity, and community-driven enhancements make it a valuable asset in building contemporary web applications.
