d) If the appliance is installed in a room or internal space with other
opened flued appliances, then the size of the air vent necessary should
be calculated in accordance with BS 5440-2 Table 2.
e) Where an open flued system is used, and the flue duct air inlet
is within a compartment then high and low level air vents are
necessary in the compartment, the size of the vents should be
calculated in accordance with BS 5440-2 Table 2.
3.5 CONDENSATE DISPOSAL
The condensate drain connection is suitable for either 21.5 mm or
22 mm plastic push fit or adhesive overflow pipes and fittings. It
should be piped to drain, preferably within the building,
maintaining a continuous 2.5° fall away from the appliance. If the
drain is routed to outside it should be to a drain or soak away,
and any external pipe work should be in 32 mm. Insulation to
protect from freezing in cold weather conditions is also advisable.
Note if the appliance is installed in a garage all pipe work should
be in 32 mm. Ensure that the condensate discharge system
complies with any local regulations in force.
3.6
GAS SUPPLY
a) The Gas Supplier should be consulted at the installation
planning stage in order to establish the availability of an adequate
supply of gas.
b) An existing service pipe MUST NOT be used without prior
consultation with the Gas Supplier.
c) A gas meter can only be connected by the Gas Supplier or by
their contractor.
d) An existing meter and/or pipe work should be of sufficient size
to carry the maximum appliance input plus the demand of any
other installed appliance. (BS 6891: 1988).
A minimum of 22 mm diameter pipe work is
recommended within 1000 mm of the appliance gas cock.
e) Natural gas appliances:
The governor at the meter must
give a constant outlet pressure of 20 mbar (8 in.wg) when all
appliances on the system are running.
Propane appliances: The regulator must give a constant outlet
pressure of 37 mbar (14.9 in.wg) when all appliances on the
system are running.
f) The gas supply line should be purged. WARNING: Before
purging open all doors and windows, also extinguish any
cigarettes, pipes, and any other naked lights.
g) The complete installation must be tested for gas tightness.
3.7 CENTRAL HEATING SYSTEM
a) The appliances incorporate all the components necessary to
allow them to be connected to a sealed central heating system.
Refer to Figure 7a for a typical system design, which incorporates
radiators, and a drain facility that must be provided at the lowest
point in the system to allow complete drain down.
b) The installation should be designed to operate with a flow
temperature of up to 95 °C.
c) A sealed system must only be filled by a competent person.
d) The available pump head for the appliances are given in Figure 6.
*Recommended by the boiler manufacturing industry to prevent
pluming nuisance and damage to buildings.
