B. If it is a new installation have the gas authorities check
the meter size and piping to assure that the unit is
supplied with the necessary amount of gas pressure
required for operation.
C. If it is additional or replacement equipment have the
gas authorities check the pressure to make certain that
existing meter and piping will supply fuel to the unit with
not more than 1/2” water column pressure drop.
NOTE: When checking gas pressure, be sure that all other
equipment on the same gas line is on.
The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system with pressures in excess of
1/2 PSIG (3.45kPa).
Appliances Equipped With Casters
1. The installation shall be made with a connector that
complies with the Standard for Connectors for Moveable
Gas Appliances, ANSI Z21.69/CSA 6.16, Addenda Z21.69B-
2006/CSA 6.16B-2006 (or latest edition), and a quick-
disconnect device that complies with the Standard for
Quick Disconnects for Use with Gas Fuel, ANSI Z21.41/
CSA 6.9, Addenda Z21.41A-2005/CSA 6.16A-2005 (or
latest edition).
2. The front casters on the appliance are equipped with
brakes to limit the movement of the appliance without
placing any strain on the connector or quick-disconnect
device or its associated piping.
3. Please be aware that the required restraint is attached to
a bracket (which is located on the rear caster closest to
the gas connection) and if disconnection of the restraint
is necessary, be sure to reconnect the device after the
appliance has been returned to its original position.
Appliances Equipped With Legs
1. Raise the front of the appliance an block. Do not lay the
appliance on its back.
2. Position leg insert in leg retainer opening and tap upward
until the insert seats at the collar flange.
3. Repeat leg insert installation for the other legs and adjust
all four legs to the same height.
4. Legs can be further adjusted to level the appliance and to
compensate for uneven flooring.
Ventilation Air
The following notes are intended to give general guidance.
For detailed recommendations, refer to the applicable
code(s) in the country of destination.
Proper ventilation is highly essential for optimum
performance. The ideal method of ventilating open-top
equipment is the use of a properly designed canopy which
should extend six inches (152mm), beyond all sides of the
appliance(s) and six feet, six inches (1981mm) above the
floor.
A strong exhaust will create a vacuum in the room. For an
exhaust vent to work properly, replacement air must enter
the room. The amount of air that enters must be equal to the
amount exhausted.
All gas burners and pilots need sufficient air to operate. Large
objects should not be placed in front of the appliance(s) that
would obstruct the flow of air into the front.
Gas Connection
The local gas authority should be consulted at the
installation planning stage in order to establish the
availability of an adequate supply of gas and to ensure
that the meter is adequate for the required flow rate. The
pipe work from the meter to the appliances must be of an
appropriate size.
All fixed (non-mobile) appliances MUST be fitted with a
manual gas-cock upstream of the appliance to provide a
means of isolation for servicing or cleaning purposes. A
union or similar means of disconnection must be provided
between the gas-cock and the appliance.
A manually operable valve must be fitted to the gas supply
to the kitchen to enable it to be isolated in an emergency.
Wherever practical, this shall be located either outside the
kitchen or near to an exit in a readily accessible position.
Where it is not practical to do this, an automatic isolation
valve system shall be fitted which can be operated from a
readily accessible position near to the exit.
At locations where the manual isolation valve is fitted or
the automatic system can be reset, a notice MUST be fitted
stating:
“ALL DOWNSTREAM BURNER AND PILOT VALVES MUST
BE TURNED OFF PRIOR TO ATTEMPTING TO RESTORE THE
SUPPLY. AFTER EXTENDED SHUT OFF, PURGE BEFORE
RESTORING GAS SUPPLY.”
