INSTALLATION

Important

Your attention is drawn to the latest GAS SAFETY REGULATIONS 2000.

This appliance MUST be installed by a competent person in accordance with these and any other relevant

regulations. Users, too, should be aware of the regulations governing the use of gas appliances,

particularly with respect to the need for regular servicing.

Your attention is drawn to the requirement that those parts, which have been protected by the

manufacturer or his agent, are not to be adjusted by the installer.

Before Installation

Before commencing installation, remove all packaging materials from the appliance. It is suggested that

any protective film adhering to the stainless steel panels should be left on until installation is completed.

BUT THIS MUST BE REMOVED BEFORE COMMISSIONING OR OPERATING THE APPLIANCE.

Check appliance Data Plate (located at the top rear of the appliance) to ensure appliance is correct for

local gas supply. Note: - During installation, always employ accepted standards of gas fitting and

National Water Council practices.

This appliance is to be installed with sufficient ventilation to prevent the occurrence of unacceptable

concentrations of substances harmful to health in the room in which they are installed.

Positioning and Levelling:

1) Place steamer in position, allowing a minimum of 125mm (5”) at the sides and 160mm (6”) at

rear for connection of gas and water supplies and ensure that there is a minimum distance of 1

Metre between the top of the appliance and any overhead ceiling or overhanging shelf. A

minimum distance of 1 Metre must be allowed at the front of the appliance for door opening and

unloading of food from the cooking compartment. Ensure that position of installation is free

from draughts.

2) Using a spirit level, check the steamer is level in two planes.

3) If necessary, use levelling feet to bring appliance level. Turn anti-clockwise to lower or clockwise

to raise appliance.

Installation (cont.)

Connection to Mains Services:

1) Provide a rigid gas pipe no smaller than the size of steamer inlet connection, together with an

elbow or other suitable means of connection. NOTE: - Although rigid pipe is recommended,

armoured flexible pipe of a type approved for catering applications may be used.

2) It is also recommended that an easily accessible stop valve be provided adjacent to the

appliance.

3) Provide a rigid water supply pipe no smaller than the size of the inlet, together with an elbow or

other suitable means of connection. NOTE: - Although rigid pipe is recommended, a flexible

hose of a type approved for potable water may be used.

4) It is recommended that an easily accessible stop tap be provided adjacent to the appliance.

5) Connect steamer to gas & water supplies, ensuring that any dirt or swarf is removed.

It may be necessary to fit a Double Check Valve (JE-DCV) in the water supply in some areas to

meet Local Water Bylaws.

NOTE: - Feed tank overflow maybe piped away by connecting a 1” Bore flexible pipe fastened

with a “Jubilee” type clip.

Testing:

1) Turn on gas supply and check that all joints are gas-tight using leak detection fluid.

2) Turn on external and internal water taps and check that all joints are water-tight.

3) Remove steamer furniture and interceptor tray. Check that water level is up to the mark on rear

of steamer tank. Open and shut drain valve to check that ball valve operates, to bring water back

to correct level.

4) Connect a water gauge to pressure test point on burner injector elbow, light appliance and check

that the pressure shown on gauge agrees with that on Data Plate.

5) As governor is factory pre-set, adjustment is not necessary.

6) Check that pilot flame impinges correctly on flame failure thermopile to ensure continuous

operation of burner. Adjust pilot flame, if necessary, using adjusting screw (beneath screw at

bottom right) on multifunction valve.

Users Instructions (cont.)

Controls Operation:

Control Knob - Controls multifunction valve to allow gas to flow to main and pilot burners

marked with z “OFF”, * “PILOT” and the flame symbol “ON” positions.

Water Taps - Inlet tap controls flow of water into steamer. Drain tap allows water tank to be

drained.

Lighting the Steamer:

WARNING: - DO NOT LIGHT BURNERS WHEN TANK IS EMPTY

Ensure that the water supply to the steamer is turned on before use.

1) Open both internal and external stop valves. Remove steamer furniture and interceptor tray.

Check that water level is up to mark on rear of steamer tank. Open and close drain tap and check

that ball valve operates, to bring water back to correct level.

2) Replace steamer furniture and interceptor tray. Turn control knob from z “OFF” to * “PILOT”,

push in knob and apply a taper (or press optional piezo ignition) to light the pilot.

3) Hold in knob for approximately 20 seconds, release and check that pilot remains alight.

4) If pilot is extinguished on releasing knob, repeat steps 2 & 3. If pilot remains alight, turn control

knob to “ON” to light main burner.

steamer reaches full temperature, then open the door in accordance with special safety

procedure given below. Load steamer quickly with food and close door securely.

6) A fixed calibration thermostat controls steamer, which is not adjustable, by the user. When set

temperature is reached thermostat cuts-in and burner operates at approximately 1/3 gas rate,

through by-pass fitted in control valve.

NOTE: - When first lighting the appliance after installation or after an extended shut-down period, it

may be necessary for gas control knob to remain pushed in for some time before pilot will light,

owing to presence of air in gas line.

Turning off the Steamer:

2) For long periods, turn control knob to z “OFF”, close all external gas stop valves, if fitted, and

external and internal water valves. Drain tank and thoroughly dry inside of tank.
