When the burner control is set to LOW, the surface of the ceramics should glow very dull red and the flame should have a blue- haze color. The flame should not flutter or “pop.” If necessary, adjust the burners (see page 21) and/or LOW setting (see page 20). Radiant: Turn the burner control to HIGH and visually check that the burners have ignited. Flames from the tube burner will spread over the stainless steel radiants. The stainless steel radiants will glow red within 3 minutes. 4. Check that gas supply is adequate by simultaneously turning on all burners of all appliances connected to the same gas supply to their highest setting, then again checking that the broiler's pilot and burner flames have correct appearance and height. 5. Turn off all burners and allow the broiler to cool. STEP 7: WIPE-CLEAN AND SHUT-DOWN APPLIANCE 1. Wipe clean all surfaces. 2. Unless the broiler is to be placed in service immediately, shut off the gas supply. 3. Make sure that a copy of this manual is available to the people who will operate and maintain the broiler.

TO ASSURE YOUR CONFIDENCE, CONTACT YOUR AUTHORIZED SERVICE AGENCY FOR RELIABLE SERVICE, DEPENDABLE ADVICE OR OTHER ASSISTANCE, AND FOR GENUINE FACTORY PARTS. NOTICE INSTALLATION OF OTHER THAN GENUINE BLODGETT RANGE RANGE PARTS WILL VOID THE WARRANTY ON THIS EQUIPMENT. The serial plate is located under the broiler bottom drip pan at the front, toward the left (see Figure 1 on page 3). Replacement parts (including parts not listed in this manual) may be ordered either through a Blodgett Range Authorized Parts Distributor or a Blodgett Range Authorized Service Agency. When ordering parts, please supply the Model Number, Serial Number, Part Number, and Part Description. TROUBLESHOOTING Problem Look for Not enough heat – Low pressure in gas supply – Restriction in gas piping and/or valves – Misalignment of burner orifice tube – Clogged burner orifice – Incorrect burner orifice Too much heat – Incorrect orifices – Defective or incorrectly set pressure regulator Burner flame has excessive blue haze – Obstruction of combustion-air intake on rear of broiler – Exhaust gases blocked by objects sitting on top of broiler – Low pressure in gas supply – Misalignment of orifice tube Burner flame fluttering – LOW setting of burner valve out of adjustment Burner flame popping (Infrared) – Cracked or loose ceramic Slow burner ignition – Pilot flame out of adjustment – Pilot alignment out of adjustment Pilot outage – Pilot flame out of adjustment – Draft condition – Pilot orifice clogged – Incorrect pilot orifice INSTALLATION & OPERATIONS MANUAL 1186529 REV 3 (12/06) PAGE 19 OF 24 INFRARED/RADIANT COMPACT BROILER 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. Figure 8 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 broiler weighs about 175 pounds (77 kilograms). Refer to the installation procedure in the previous section of this manual for guidance. ADJUSTMENT OF BROILER 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 slot 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.
