The orifice caps must be kept clean. To clean the orifices, use the following guidelines:
Remove the orifices to clean them. Clean hole in orifice hood with a toothpick

, being careful not to break the toothpick off inside the orifice. If cleaned while installed on

orifice assembly, grease will be pushed into the hood and will eventually re-plug the hole. Brass is an
extremely soft metal, and a paperclip or other harder, abrasive tool can easily enlarge the orifice
diameter leading to possible hazardous conditions.

Air Shutters:

The air shutters are located at the end of the top burner manifold and the ends of the broiler burners.
They are used to regulate the air/fuel mixture.

Typical adjustment range:

Top burners: 1/2 - 3/4 open (On top burner manifolds)
Bottom burners: 3/4 open

Insufficient air (shutter not open enough) results in longer blue to yellow flame.

Excessive air (shutter open too far)

results in sharp translucent blue flame to flame that lifts off burner ports.

Pilot Flame:

When the pilot flame burns out beyond the lighter tube (bottom griddle), reduce the flame so that the
flame is touching and slightly around the lighter tube. The adjusting screw is on the gas supply line
between the thermostat and the pilot assembly itself. The pilot adjusting valves for the top lighter tubes
are found on the main gas manifold at the base of the unit.

Top Burners:

Clean top burners using the following steps:

1. Scrub thoroughly with a wire brush.
2. Use a #49 drill (or drill sized as close as possible without over-sizing) to re-open ports to their

original size (or as close as possible). Note: Over-sizing ports will cause improper operation
resulting in poor performance of the grill.

Ceraform Fiber Board:

Ceraform is a non-asbestos fiber board. It keeps the top griddle plate from getting too hot. It can be
damaged by water and/or by scraping it across the top of the cabinet when removing or replacing the
top griddle plate.

Inner and Outer Track Assemblies:

The inner track uses a bolt to hold it in place. Remove and replace for monthly cleaning and greasing
of the track. Removal of the bolt while in use will cause the track to slide out and cause excessive wear
on both the track and the flexible gas connector. The safety bolt is to be removed ONLY for full cleaning
of the tracks and then replaced.

Gas Pressure Regulator:

If there is little or no gas in the burners, the vent hole on the regulator is possibly plugged with grease.
To prevent the vent hole from plugging, cover the regulator

with aluminum foil. The regulator

should be installed on the main gas line between the grill and shut-off valve. Regulator should be
placed in a location that will minimize grease exposure.

from the inside to the

outside

NOTE: this is a fuel-

rich setting that can produce excessive carbon monoxide.
