Meters (Natural Gas); Gas Pipe Size; Gas Connection; Gas Pipes & Fittings - Stanley Brandon Dry Installation And Commissioning Instructions

METERS (NATURAL GAS)

A suitable gas meter must be connected to the
service pipe either by a representative of the gas
supplier or by an appointed contractor. If using an
existing meter have it checked to ensure that the
meter is capable of dealing with the total rate of gas
supply needed (see Technical Data).

GAS PIPE SIZE

It is important that the correct service pipe size be
used in order to ensure an adequate gas supply of
1.48 cubic meters/hr (52.5 Cubic ft./hr) for Natural

on the distance between the supply meter, the
pressure drops caused by bends and the expected
pressure drop in the gas mains at peak demand
times. (See B.S. 6891).(If in doubt contact your local
gas supply company)

GAS CONNECTION

A FLEXIBLE HOSE MUST NOT BE USED TO
CONNECT THE GAS SUPPLY TO THE COOKER.
WARNING: To avoid pipe sealing compounds from
entering into the gas train, do not apply sealing
compound to the first two threads at the tip of the
gas connection. (See Fig.19)
NOTE: Clean off any excess pipe compounds from
connections.
A shut off valve must be fitted as close as possible
(See Fig.20) to the cooker and should be accessible
at all times. A combined valve and elbow fitting is
supplied with the appliance, located in the oven
package. One end of this fitting simply fits onto the
gas train located at the bottom left hand side of the
cooker. The other end has a 3/4" BSP Male thread.
If it is necessary to use an alternative valve, select
a valve which does not cause a restriction in the flow
or a pressure drop across it when open, and install
it as close as possible to the cooker.

GENERAL MAINTENANCE

It is important that the user is familiar with their
cooker and that they ensure regular checks and
maintenance which can limit unnecessary break-
downs.

SERVICING

To ensure continued efficient and safe operation of
the appliance it is recommended that it is checked
and serviced as necessary at regular intervals. The
frequency of servicing will depend upon the
particular installation and usage, but in general once
a year should be adequate.
