4.0
Installation
The boiler installation must be in compliance with BS 5410 and the Building Regulations.
Failure to install and commission in accordance with the instructions contained
within this booklet will invalidate the warranty.
4.1
Service Access
24” (600mm) clearance should be provided above and in front of the boiler (and the
rear for Slimline Kabin Paks) to allow for routine servicing. When top servicing boilers
are placed under a worktop ensure that the worktop is easily removed.
4.2
Hearth
The boiler hearth temperature is between 50
°
C and 85
°
C to comply with the Building
Regulations. The boiler should be stood on a rigid, non-porous, non-combustible base,
which is not softened by warmth. For the heavier industrial boilers it would be advisable
to have a level concrete base raised 50mm above floor level.
4.3
Heating System
The heating system should be installed to HVCA current codes of practice and the
recommendations made in the relevant British Standards.
The use of inappropriate pipe sizes and incorrect plumbing leading to system and
boiler noise is not covered under the boiler warranty.
It is recommended that the flow and return pipes are connected on opposite sides of
the boiler.
It is recommended that new and existing systems are commissioned in accordance
with BS7593 : 1992 ‘Treatment of water in central heating systems’. It is recommended
that a non-corrosive commissioning cleanser is used when flushing the system.
We would also recommend that the system is further treated with a corrosion inhibitor.
These products should be used strictly in accordance with the manufacturers
instructions.
In areas of hard water a suitable water softener would also be recommended.
4.4
Sealed Systems
All Warmflow boilers are suitable for use on a sealed heating system. It is recommended
that a CE approved pressure relief valve (PRV) set at 3 bar is fitted to the system. The
industrial bluebirds can be fitted with a 4 bar PRV. On the system boiler a 3 bar PRV
has been factory fitted.
