Garland STW286A - Manual (Page 7)

Part # 4517957 Rev.13 (02/10/11) Page 7
In the United States the installation must comply with
the National Fuel Gas Code ANSI Z223.1, (latest edition),
NFPA No. 54, (latest edition), and the National Electrical
Code ANSI/NFPA 70, (latest edition), and/or local codes to
ensure a safe and efficient operation.
• This equipment must be electrically grounded in
accordance with local codes, or in the absence of local
codes, with National Electrical Code, ANSI/NFPA 70, or the
Canadian Electrical Code, CSA C22.2, as applicable.
• The appliance and its individual shut-off (supplied by
others) must be disconnected from the gas supply piping
system during any pressure testing of the system at
pressures in excess of 1/2 PSIG (3.45 KPA). The appliance
must be isolated from the gas supply piping by closing its
individual manual shut-off (supplied by others) during any
pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 PSIG (3.45 KPA).
• Adequate clearance must be provided for servicing and
proper operation.
Clearances
Minimum installation clearance to adjacent combustible
walls and type of floor or base:
MINIMUM CLEARANCES STW286A
LOCATION CLEARANCE
Left Hand Side 7" (178mm)
Right Hand Side 7" (178mm)
Rear 6" (152mm)
TYPE OF FLOOR OR BASE
Combustible
Location
The range should be installed on a firm, smooth and level
floor designed to withstand the weight of the fully laden
appliance. Any openings in the wall beside the appliance
should be sealed.
Appliances Equipped with Casters
• 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).
• 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.
• Be aware; required restraint is attached to a bracket,
which is located on the rear caster closest to the gas
connection. If disconnection of the restraint is necessary,
be sure to reconnect the device after the appliance is
returned to its original position.
Ventilation & Air Supply
The area in which the appliance is installed must be
adequately ventilated to provide air for combustion, removal
of products of combustion and removal of steam, etc. Proper
ventilation is essential for optimum performance.
The ideal method of ventilating 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 equal 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) which would obstruct the flow of air into the
front.
Gas Connection:
The gas pipe connection is made at the rear right hand side
of the equipment. The size of the pipe work supplying the
appliance must not be less than the inlet connection which
is 3/4” NPT. An isolating valve is recommended to be close to
the appliance to allow shut down during an emergency or
routine servicing. After installation, the complete pipe work
must be checked for soundness.
