Location

1. This oven must be installed in an area of adequate air supply.

Adequate ventilation is essential, to prevent dangerous build
up of combustion products. DO NOT obstruct the air flow
around the ventilation slots.

2. This oven must be fitted on supplied legs in all installations.

(When installed on a manufacturers stand, the legs are used
to locate the oven in the correct position.

3. All air for burner combustion is supplied from underneath the

appliance. The legs must always be fitted and no obstructions
placed on the underside or around the base of the appliance,
as obstructions will cause incorrect operation and / or failure
of the appliance.

4. Installation must allow for a sufficient flow of fresh air for the

combustion air supply.

5. The area around the appliance must be kept free and clear

from combustibles.

6. Position oven in its approximate working position. It should be

positioned so that the control panel and oven shelves are
easily reachable for loading and unloading.

7. Use a spirit level to ensure oven is level from side to side and

front to back. (If this is not carried out, uneven cooking could
occur).

1. Remove all packaging and transit protection including all
protective plastic coating from exterior stainless steel panels.

2. Check the oven and supplied parts for damage. Report any
damage immediately to the carrier and distributor.

3. Check that the following parts have been supplied with your
oven:-

Gas Connection

Important:

For appliances installed on castors (double stacked, on
base stand or on proofer), the installation shall be made
with a connector that complies with:-

- ANSI Z21.69 • CSA 6.16 - Connectors for Moveable Gas

and a Quick Disconnect Device that complies with:-

- ANSI Z21.41 • CSA 6.9, (2) - Quick Disconnect Devices

Adequate means must be provided to
limit the movement of the appliance
without depending on the gas connector
and the quick-disconnect device or its
associated piping to limit the appliance
movement.
The restraint anchor point is located
below the gas connection point as shown.

A ½" N.P.T connection is provided at the bottom rear of the oven.

It is important that adequately sized piping run directly to the
connection joint on the oven with as few tees and elbows as
possible to give maximum supply volume.

A suitable jointing compound which resists the break down action
of LPG must be used on every gas connection.

Check all gas connections for leakages using soapy water or other

supply and an isolation switch mounted adjacent to, but not
behind the oven and must be readily accessible to the operator.
This switch must be clearly marked and readily accessible in case
of fire.

Check electricity supply is correct to as shown on Technical Data
Plate on front right hand corner of oven side panel.
Ensure oven is fitted with appropriate power cord and plug.

Check the technical data plate located on the front right hand
corner of the oven, for correct operating pressure and gas orifice
size for the gas being used, before operation.

The appliance combination gas valve is fitted with an
internal regulator for adjusting operating pressure. To access,
remove appropriately marked service panel from beneath oven
door. Unscrew and remove regulator cap from gas valve.

Adjust regulator to achieve stated pressure. Also refer to
