GAS CONNECTION
The gas supply must use the nearest
gas inlet pipe which is located at the left
or the right hand side at the rear of the
appliance (fig. 7.1). The unused end
inlet pipe must be closed with the plug
interposing the gasket.
Flexible hoses can be used where the
sited ambient temperature of the hose
does not exceed 70
°
C. These hoses
must be manufactured in accordance
with BS669 part 1 and be of the correct
construction for the type of gas being
used.
The hose should not be crushed or
trapped or be in contact with sharp or
abrasive edges. It should also not be
subjected to corrosion by acidic
cleansing agents.
The hose should also be connected in
such away that it does not touch the
floor.
NB: Gas hoses designed for natural gas
MUST NOT be used for supplying LPG
gas (LPG gas hoses can be identified
by a either a red band or stripe on the
rubber outer coating of the hose).
To avoid damage to the appliance gas
rail inlet pipe the fittings should be
tightened using two suitable spanners
(fig. 7.2).
After connection to the mains gas
supply the couplings should be
checked for gas soundness/tightness
as per current regulations for the gas
type being used.
