Rangemaster RGG60 manual Gas Connection, Pressure Testing, Safety Information, Fixing the Hob

INSTALLATION

Check the appliance is electrically safe and gas sound when you have finished.

Gas Connection

Before connecting the appliance, check that it is suitable for your gas and electricity supply. This information is on the data label fixed to the underside of the hotplate. Gas connection must comply with the relevant standards and regulations in force.

The gas connection point is located as shown in the diagram below. The inlet union is Rp ½.

Pressure Testing

The gas pressure can be measured at one of the hotplate burner injectors. Lift off a burner head. Fit the pressure gauge to the injector. Turn on and light one of the other hotplate burners. Turn on and push in the control knob for the burner with the pressure gauge fitted to let gas through.

The appliance must be connected to the gas supply system with one of the following:

A rigid steel pipe

������

ArtNo.050-0012�������Gas pressure table� ������

Table 5-1

The joints of this pipe must consist of threaded fittings conforming to the standards. The use of seals such as hemp with suitable cement, or Teflon tape, is permitted.

A copper pipe

The joints of this pipe must consist of unions with mechanical seals.

A flexible hose

A hose is not supplied by with the hotplate. Hoses may be purchased at most builders’ merchants.

The hose should be fitted so that both inlet and outlet connections are vertical so that the hose hangs downwards.

The hose must be in accordance with the relevant standards. In the UK these are:

For Natural Gas the flexible hose must be in accordance with BS 669.

For LP Gas it should be capable of 50mbar pressure, 70°C temperature rise and carry a red stripe, band or label.

Safety Information

Ensure that the gas supply pipe is never able to touch moveable parts of the built-in cabinet (e.g. drawers). It must not pass through compartments that could be used for storage purposes.

When using a flexible hose, it is essential to comply with the following instructions:

•No part of the pipe must be able to touch parts the temperature of which exceeds 75°C

•The pipe must not be pulled or twisted, throttled or tightly bent.

•It must not come into contact with sharp edges or corners.

•It must be easy to inspect the entire pipe length in order to check its state of wear.

•The pipe must be replaced within the date stamped on the pipe itself.

If in doubt, contact your supplier.

After completing the gas connection check the hotplate is gas sound with a pressure test.

Turn off the burners. Reassemble burner top, making sure it is reassembled in the correct way on the burner body.

Fixing the Hob

The hob must be sealed to the work surface to prevent liquid from entering into the cabinet. A tape seal is supplied with the hob.

Carefully follow these instructions to correctly apply the seal: Turn the hob over and place in on a secure, level surface. Detach the seal from the backing, checking that the transparent protection still adheres to the seal itself. Carefully position the seal along the edge of the hob. Take special care in the corners making sure there are no gaps. The ends of the strips must fit together without overlapping.

If the surface that the hob is to be fitted to is tiled or is not reasonably smooth, additional sealing with a waterproof silicone sealant may be required.

Turn the hob back the right way up and position it in the worktop cut-out.

Secure the hob to the worktop using the brackets supplied. The positioning of the bracket is dependent on the thickness of the worktop as shown in (Fig.5-4).

Note: Slide the optional sleeve onto the bracket if fitting to thin work surfaces.

Locate the bracket to the slot on the hob base and then tighten the retaining screw until it is locked to the worktop.
