B.6 Gas Connection- 3/4” N.P.T.
At rated input the gas supply should deliver a minimum pressure of at least 15 mbar (6" water column)
at the broiler connection for natural gas. Incoming gas supply pressure must not exceed 50 mbar (14"
water column).
Note
: The installation of this appliance must conform with local codes, or in the absence of local codes,
with the National Fuel Gas Code, ANSI Z223.1, Natural Gas Installation Code, CAN/CGA-B149.1
including:
1. The appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of
1/2 psi (3.45 kPa).
2. The appliance must be isolated from the gas supply piping system by closing its
individual manual shutoff valve during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psi (3.45 kPa).
B.7 Installing Gas Appliance Connectors and Flexible Gas Lines Correctly
For safety in the kitchen area, and to insure maximum service life, it is vitally important to correctly install
connectors. The connector shall comply with the Standard for Connectors for Moveable Gas Appliances,
ANSI Z21.69 or CAN/CGA-6.16 and a quick disconnect device that complies with the Standard for Quick-
Disconnect Devices for use with gas fuel, ANSI Z21.41 or CAN1-6.9
In order to avoid sharp kinks or excessive bends that could have a damaging effect on the connector, it
may be necessary to attach pipe elbows in order to bring the connector into its proper plane. For easy
movement of the appliance, the connector should be installed with a "lazy" loop for minimum tension.
Note: Gas appliances should be disconnected prior to maximum movement. (Minimal movement is
possible to connect hose.)
B.8 Restraining Device Installation and Use
This high strength restrainer is to be used with all moveable (castered) appliances. It fully complies with
American Gas Association requirements. References: Z21.69, Z83.11, and Z21.41 with current revisions.
Installation is quick and positive. In Canada, device is in accordance with CAN 1-6.9-M70 Quick
Disconnect Devices for use with gas fuel, and CAN 1-6.10-88 metal connectors for gas appliances.
Correct length for any appliance is simply a matter of loosening two adjuster clips (1) and re-tightening.
(3" to 6" shorter than appliance connector is desired length.) Restrainer is made of heavy duty steel
cable, with a strong scissor hood (2) at one end, and an equally strong spring hook (3) at the other.
Cotter pin (4) is supplied to secure the installation. For proper attachment to the broiler, use the supplied
hardware to attach the device to the holes in the shear plate of the broiler stand.
NOTE: If disconnection of the restraint is necessary, reconnect the restraint after the appliance
has been returned to its originally installed position.
