- A gas fire with a solid fuel effect is to be installed in an existing chimney
hearth. What needs to be done to get an adequate air supply and what would
be the typical size needed?
- A small kitchen in a one bedroom flat is to have a gas cooker installed.
The kitchen is 1.8m x 2.3m long with 2.3m headroom. There is an openable window
to the kitchen, so what size of airbrick would be needed for adequate permanent
ventilation.
- A new flat is to have a balanced-flue boiler installed in a small cupboard
off the entrance hall. Assuming that the cupboard is required to have a fire-resiting
door and partition to the entrance hall, what ventilation requirements are
needed to the cupboard?
- A small industrial unit in a business park is to have a gas fired air heater
installed with a rated input of 50kW. How much permanent ventilation is needed?
If the gas installer proposes to use the cracks around the large sliding door
to provide the air supply, why would that not be acceptable?
Discharge of products of combustion
- A balanced flue gas boiler is to be installed in a kitchen next to the window.
How close can the flue be to the window? If the flat was on the ground floor
would it be necesary to provide a guard to the outlet?
- A resident telephones you with regard a neighbours flue from a gas boiler.
The flue is coming through a ground storey level wall facing the boundary
with their garden. How far away should the flue be from the boundary?
- A terraced house is having a loft converted including in the installation
of large dormer windows. The existing house has front and back chimney stacks
along one party wall. How close does the dormer have to be to this party wall
before the chimney flue pot has to be raised to at least 600mm above the dormer
roof?
- It is proposed to bring back into use an abandoned chimney. What test could
be carried out to show that it is still satisfactory for use?
Protection of the Building
- A terraced house party wall has chimney breasts either side. The back to
back fireplaces are recessed into the Party Wall to leave 102.5mm thick brick
between. If the owner of one side wishes to remove their chimney breast completely,
how thick should the recess be filled and how could that be done?
- An existing chimney has had the hearth removed in the past when it was sealed
up. The owner now wants to bring the chimney back into operation. How far
in front of the chimney breasts does it need to project? How wide does the
hearth need to be and how thick?
- A chimney stack on a party wall has had to be re-built for its top 1.5m.
The builder asks if the chimneys should be parged? What is meant by parging?
What would be an acceptable alternative?
- How close can timber be placed next to a solid fuel chimney?
Building Regulations
- An owner of a building is a Do-It-Yourself enthusiast. The owner intends
to install a new gas boiler for a central heating system. Is a Building Notice
or Full Plan Notice required to be submitted? If the owner was employed by
a Corgi registered person would that make any differance?
- A house is being converted into two flats. The builder claims the work is
complete but has not installed the gas boiler for security reasons. The builder
requests that you issue a completion certificate which will allow a sale to
be made. After that the boilers will be installed. Can you agree with this
request? State reasons?

new buildings flank wall. The new building is to be a storey higher than the
