INFRARED CHEESE MELTER SERVICE
INSTALLATION AND OPERATION MANUAL 1186531 REV 0 (12/05) PAGE 19 OF 28
ACCESS TO SERVICEABLE PARTS
Some serviceable parts are only accessible by removing body side panels and the front panel.
The main front panel is fastened with six sheet-metal screws. To remove the front panel, remove these screws, as
well as the burner-control-valve knob and the rack-height-position-lever knob. The main front panel can then be pulled
forward and removed. Each body side panel is fastened with two sheet-metal screws. Remove body-side screws and
slide the body side forward and away from the unit.

Access to Serviceable Parts
If necessary (or convenient), wall-mounted and flue-riser-mounted models can be un-mounted for servicing or repairs.
Use two people since the Cheese Melter weighs about 175 pounds (79 kilograms). Refer to the installation procedure
in the previous section of this manual for guidance.
ADJUSTMENT OF CHEESE MELTER PILOTS
The pilots are adjusted at the factory. If later the pilots are over-adjusted to the point where the flame is leaving its
port, or “blowing off,” the result is an unstable condition in which the pilot may extinguish. If necessary, adjust the
pilots using the following procedure:
1. If necessary, light the pilots.
2. Locate the pilot adjustment screw (which adjusts both pilots). It is a small slotted screw located on the pilot valve,
and is accessed though the plugged hole in the front panel above the control-valve knob.
3. Turn the pilot adjustment screw to adjust the size of the pilot flames. The flame on each pilot should be large
enough to extend along the flame carrier to the burner surface.
ADJUSTMENT OF LOW SETTING
The minimum gas flow to the burners is controlled by the burner valves. It provides an infinite variable adjustment
from low to high. Turn the knob to the desired position so that when the Cheese Melter control knob is in the LOW
position, the burner flames do not flutter or “pop,” but rather burn with a dull red or a blue haze.
