Remeha Gas 350

Suitable chemicals and their use should be discussed 
with a specialist water treatment company prior to car-
rying out any work. The specification of the system and 
manufacturers recommendations must be taken into 
account, along with the age and condition of the system. 
New systems should be flushed thoroughly to remove all 
traces of flux, debris, grease and metal swarf generated 
during installation. Care to be taken with old systems to 
ensure any black metallic iron oxide sludge and other 
corrosive residues are removed, again by thoroughly 
flushing, ensuring that the system is drained completely 
from all low points.

NOTE:

  Please ensure that the new boiler plant is not in 

circuit when the flushing takes place, especially if clean-
sing chemicals are used to assist the process.

Under no circumstances is the boiler to be operated 
with cleaning chemicals in the system.

To Summarise:

Minimise water loss;

Prevent pumping over in open vented systems;

Provide adequate air venting at all high points;

Keep pH level between 7 - 9 when using additives;

Maximum chlorine content of 200 mg/l;

Take advice on the suitability of inhibitors.

4.1.5 Noise level

The noise level measured around the boiler depending 
on boiler room construction is about 50 dBA. Noise 
levels taken at 1 meter from the boiler.

4.2 Chimneys

The average flue gas temperature is so low  (108-
173°C) that the chimney must be made in accordance 
with the guidelines of British Gas, BS 6644 and IG 10. 

4.3 Installation 

standards 

The following instructions must be adhered to when the 
Remeha Gas 350 is installed:
Gas Safety (installation and use) Regulations 1984 (as 
amended).
In addition to the above regulations, this boiler must be 
installed in compliance with:

Current I.E.E. Regulations for electrical installations;

Local building regulations;

The Building Standards (Scotland);

- (Consolidation) 

Regulations;

By-laws of the local water undertaking;

Health and Safety Document No 635 ‘The Electricity 
at Work Regulations 1989’.

It should also be in accordance with the relevant recom-

Standards and Codes of Practice, viz. BS 5440 Pt 1 and 
2, BS 5449, BS 5546, 
BS 6798, BS 6891 and BG.DM2.

Lawfully all gas appliances must be installed by compe-
tent persons (e.g. Corgi, ACOPS).
Failure to install appliances correctly could lead to pros-
ecution.
It is in your own interest and that of safety to ensure that 
the law is complied with.

Important:

The Remeha Gas 350 is a certified appliance and must 
not be modified or installed in any way contrary to these 
‘Installation and Servicing Instructions’. Manufacturer 
instructions must NOT be taken in any way as when
