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 critical for optimum performance . The
ideal method of ventilating open-top equipment is the use
of a properly designed canopy that should extend six inches
(152 mm), 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 be
equal to the amount of air exhausted . An imbalance between
exhaust and replacement air can cause degradation in the
appliance’s performance .
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 .
Statutory Regulations
The installation of this appliance must be carried out by
a competent person and in accordance with the relevant
regulations, codes of practice and the related publications of
the country of destination .
The installation must conform to the National Fuel Gas Code
ANSI Z223 .1, or latest edition, NFPA No .54 - latest edition/or
local code to assure safe and efficient operation . In Canada,
the installation must comply with CSA B149 .1 and local
codes .
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 appliance must be an
appropriate size .
All fixed (non-mobile) appliances MUST be fitted with an
accessible upstream gas shut off valve as a means of isolating
the appliance for emergency shut off and for servicing . 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 .
In locations where the manual isolation valve is fitted or the
automatic system can be reset this notice MUST be posted:
“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 .”
Installation Notes
Before assembly and connection, check gas supply .
A . The type of gas for which the unit is equipped is stamped
on the data plate located behind the lower front panel .
Connect a unit stamped “NAT” only to natural gas;
connect one stamped “PRO” only to propane gas .
B . If it is a new installation have the gas authorities check
meter size and piping to assure that the unit is supplied
with necessary amount of gas pressure required to
operate the unit .
C . If it is additional or replacement equipment have the gas
authorities check pressure to make certain that existing
meter and piping will supply fuel to the unit with no
more than 0 .15 Kpa pressure drop .
D . Make certain new piping and connections have been
made in a clean manner and have been purged so that
piping compound, chips, etc . will not clog pilots, valves or
burners . Use pipe joint compound approved for natural
and liquefied petroleum gases .
NOTE: Gas pressure should be checked when the unit is
installed and all other equipment on the same line is on . The
operating gas pressure must be the same as that specified
on the rating plate . If necessary, pressure adjustment may be
made at the pressure regulator supplied with the appliance .
The appliance and its individual shut-off valve must be
disconnected from the gas supply piping system during any
pressure testing of that system where pressures are in excess
of 1/2 PSIG (3 .45kPa .)
Final Preparation
NOTE:
Your new appliance has a plastic coating to help
protect the finish from scratches during shipping . This
protective plastic film should be peeled off prior to starting
the appliance .
