SPECIFICATIONS RADIANT STEAKHOUSE BROILER

If a ventilation canopy is used, it is recommended that the canopy extend 6" (152 mm) past the broiler and that the bottom edge be located 6'6" (1980 mm) from the floor. Filters should be installed at an angle of 45° or more from the horizontal. This position prevents dripping grease, and facilitates collecting the run-off grease in a drip pan under the filter.

A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum. The exhaust fan should be installed at least 2" (51 mm) above the vent opening on the top rear of the broiler.

If the broiler is connected directly to an outside flue, a CSA design-certified down draft diverter must be installed.

In case of unsatisfactory performance by any gas appliance, check the appliance with the exhaust fan turned OFF. Do this only long enough to check whether doing so corrects any problems with equipment performance. Then turn the exhaust fan back on and let it run to remove any exhaust that may have accumulated during the test.

GAS SUPPLY

The broiler is design-certified for operation on natural or propane gases. The broiler is shipped configured and adjusted for the type of gas specified by the purchaser, which is indicated on the serial plate (see Figure 1 on page 3). Connect the broiler ONLY to the type of gas for which it is configured and adjusted.

Gas Type	Total BTU/hour	Burner Orifice	Bar Pilot.
Natural Gas	42,000 Per	No. 36 (P/N 1006436)	No. 75 (P/N 1176664)

Min. Supply Pressure

7" W.C.

11" W.C.

Manifold Pressure

6" W.C.

10" W.C.

Models with a rear gas connection have a 1" rear gas connection to an external regulator that is located at the rear bottom corner on the right side. Models with a front gas supply are connected by unions assembled to the front manifold.

Minimum supply pressure is 7" W.C. for natural gas, 11" W.C. for propane. An external pressure regulator and shutoff valve are provided. If using a flexible-hose gas connection, the inside diameter of the hose must not be smaller than the connector on the broiler, and must comply with ANSI Z21.69. Provide an adequate means of restraint to prevent undue strain on the gas connection. Test pressure should not exceed 14" W.C.

If applicable, the vent line from the gas appliance pressure regulator must be installed to the outdoors in accordance 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,or the Propane Installation Code CAN/CGA-B149.2,as applicable.

An adequate gas supply is imperative. Undersized or low-pressure lines will restrict the volume of gas required for satisfactory performance. Fluctuations of more than 25% on natural gas or 10% on propane gas will create problems and affect burner-operating characteristics. A 1/8" pressure tap is located on the manifold to measure the manifold pressure. The supply line to the broiler should be no smaller than the inside diameter of the pipe on the broiler to which it is connected.
