Issue No.1 Combined Manual 24.10.07

REGULATIONS

The installation of oil-fired boilers should comply with the following standards and codes of practice:

- BS5449 Forced circulation hot water heating systems for domestic use.

- BS5410-Part 1 Oil installations up to 45kw

- BS7593 Water treatment of hot water central heating systems

- BS7671 Electrical Regulations

- Building Regulations Part 1L and J 2002 England and Wales, Part F Scottish Regulations and

Technical Booklet L Northern Ireland.

- OFTEC Codes of Practice Published or Recommended.

After installing, the system needs to be flushed with a cleanser like Fernox Heavy Duty Restore, for

fast-acting removal of lime scale, black sludge (magnetite) and other deposits from the boiler and the

central heating system. Then add a Fernox protector to give long-term protection of the central

heating system against internal corrosion lime scale formation.

WATER CONNECTIONS

Only two connections for the heating and hot water system on a standard condensing boiler:

1. Flow from top of boiler (Fig.2) and return to top of stainless steel heat exchanger (Fig.2).

2. The PVC pipe (fig 3) is 21.5mm Ǿ and should continue from the condensate trap in side the boiler

casing, which should be plumbed to an external source ensuring one of the following options:

- Internal waste drainage system - Soil/vent stack

- External Drainage system - External condensate absorption point

NOTE: condensate pipe work must fall at least 50mm per metre towards the outlet ensuring all joints

are leak proof.

WARNING: the condensate trap must be filled with water prior to starting the boiler to

stop flue gases escaping
