NOTICE
Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the
warranty.
Be sure to inspect and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.
If a ventilation canopy is used, it is recommended that the canopy extend 152.4 mm (6”), past the appliance and that
the bottom edge be located 1981 mm (6’6”) 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, unusually
installed with a 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 609.6 mm (24”), above the vent opening at the top of the unit.

NOTICE
Due to the variety of problems encountered by outside weather conditions, venting by canopies or wall fans is
preferred over any type of direct venting.
If the unit is connected directly to an outside flue, a CSA design certified down draft diverter must be installed.
In case of unsatisfactory performance on any 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.

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). Connect the broiler ONLY
to the type of gas for which it is configured and adjusted.
The broiler has a 3/4” rear gas connection with a male NPT connector and an internal shut-off valve. Minimum supply
pressure is 7” W.C. for natural gas, 11” W.C. for propane. The broiler has an internal pressure regulator that is set for 4”
W.C. pressure for natural gas or 10” W.C. pressure for propane gas. 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 (or CSA
6.16). Provide an adequate means of restraint to prevent undue strain on the gas connection.
If applicable, the vent line from the gas appliance pressure regulator shall 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/NFPA 54 or the Natural Gas
and Propane Installation Code CSA B149.1, 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 adjacent to the pressure regulator to measure the
pressure. The supply line to the broiler should have an inside diameter no smaller than 3/4”.
