5 BoILER LocATIoN AND cLEARANcES
Positioning the Boiler
The boiler body should be positioned as near as possible to
the installation site. The boiler can be moved into position by
the use of rollers under the longitudinal L profiles running the
length of the boiler. If it is necessary, due to the dimensions
of the boiler, it is possible to remove the front door and the
flue collector hood to facilitate moving the boiler into the boiler
house.
The boiler must have sufficient space as shown below to
maintain minimum clearance. It must also comply to relevant
local by laws and safety regulations. It is advisable to install the
boiler as close as possible to the chimney connection on a non
combustible floor (i.e. concrete or brick).
The surface must be flat, level, and of a suitable load bearing
capacity to support the weight of the boiler (when filled with water
- see general data table).
If the boiler is mounted on a plinth then the dimensions (see
Frame 2) must exceed the plan area of the boiler by at least
75 mm on each side.
clearances
The boiler must be positioned so that there is enough space
available to allow the following:
•
Access around the boiler for servicing.
•
Space to open the boiler front door.
•
Space to access the burner.
Recommended minimum clearances are as follows:
Rear
- All Models
(W)
500mm or adequate space to make the flue
connections and access to the flue sample point, drain
connection and any safety or control devices.
Sides
- Models 170 to 970 and 3000 and 3500
(X)
One side may be 100mm (normally the left) to permit
access to the burner cable clamp plate, the other side
must be 200mm plus the burner projection to allow the
burner door to be swung open and maintain access to
the rear. In multiple installations consideration must
also be given to the burner door hinge position and
consequent clearance.
Models 1100 to 2650
One side may be 100mm (normally the left) to permit
access to the burner cable clamp plate, the other side
must be 200mm plus the burner projection to allow the
burner door to be swung open and maintain access to
the rear. However, due consideration must be made
on the left hand side to provide access to the sludge
hole. In multiple installations consideration must
also be given to the burner door hinge position and
consequent clearance.
front
- All Models
(Y)
Not less than the length of the boiler body or 1200mm
whichever is the smaller dimension
