GENERAL
INTRODUCTION
This manual is for the Vulcan and Wolf Gas Salamander Broilers. Procedures in this manual will apply to all models unless specified. Pictures and illustrations will be of model 36IRB unless otherwise noted.
All of the information, illustrations and specifications contained in this manual are based on the latest product information available at the time of printing.
INSTALLATION, OPERATION AND
CLEANING
For detailed installation, operation and cleaning instructions, refer to Installation & Operation Manual sent with each unit. The manual is also available online at www.vulcanequipment.com.
NOTE: Using accessory options, Salamander broilers can be mounted to the wall, over a range or placed onto an appropriate table top by using 4" legs.
RACK POSITION AND GAS
SETTING
NOTE: Infrared burner models must use the full gas
setting (knob fully counterclockwise) to achieve the best burner performance and highest broiler temperatures. Lower broiler temperatures can be achieved by using a lower gas setting (knob in the range just past off but less than fully counterclockwise). When using a lower gas setting, the flame should remain lit and be steady across the entire burner surface.
For detailed information refer to RACK POSITION AND GAS SETTING in the Manual.

NOTE: The factory default air shutter positions are half open natural; full open propane.

2. Locate the pilots at the top of the broiler heating area.
3. Monitor the pilots flame and burner lighting. Pilot is in adjustment when it will stay on continually and lights the burners without delayed ignition.
4. If adjustment is necessary, rotate the screw clockwise to decrease and counterclockwise to increase flame height.
RADIANT BURNER AIR SHUTTER
ADJUSTMENT (36RB/C36RB)
The efficiency of the burner depends on a delicate balance between the air supply and volume of gas. Whenever this balance is disturbed, poor operating characteristics and excessive gas consumption may occur. An air shutter on the front of the burner controls the gas mixer balance. A yellow streaming flame on the burner is an indication of insufficient primary air.
To correct this condition, loosen the shutter screw and rotate the air shutter open until the flame begins to lift from the burner, then close the shutter slightly and tighten the shutter screw. A proper flame should be blue in color, well-defined and seated on the burner
Adjustment
The only adjustment for the Infared burner is the gas manifold pressure. Verify the pressure is set correctly as outlined under
Flame Appearance
When the Infared burner first lights you should see a small rolling blue flame, which will clear up after the burner warms. Once warm, a low profile orange flame is the best description of the Infared burner flame. In some cases, if the burner is operating correctly, you may not be able to see the actual flame. Instead you will see the glow of the ceramic bricks in the burner.
REGULATOR ADJUSTMENT.
REGULATOR ADJUSTMENT
Shut off the gas before servicing the
unit.
NOTE: Regulators come preset, but should be checked anytime one is installed. Before adjusting regulator, check incoming gas line pressure. Incoming pressure must be 6-14" W.C. for natural gas and 11-14" W.C. for propane gas. If incoming pressure is not correct, have the gas source checked and adjusted as necessary. Make sure the regulator is mounted in the horizontal position with the arrow pointing in the direction of gas flow. See

connection on the outlet side of the regulator. See opposite end of the tee to broiler incoming gas supply.
2. Turn gas supply on and light both pilots.
3. Open both valves to the full on position and check manometer reading. The reading should be 5" W.C. for natural gas and 10" W.C. for propane gas. Tolerance is ±0.3" W.C.
4. If manifold pressure is not correct, adjust the regulator as follows.
A. Remove the regulator closing nut.

sealant that is suitable for use with propane gases.
F. Apply thread sealant to pipe threads and re-

GAS ORIFICE CHECK
The gas orifice is mounted at the gas and air inlet for the burner. If burner operation seems poor and other systems have been checked, access the burner and inspect:
Gas orifice alignment - orifice should be centered in the venturi opening and perpendicular to the burner.
Check gas orifice for blockage or damage. If dirty, clean with air or water only.
Verify gas orifice is correct for the altitude.

CONTROL VALVES
Inspect the control valve for smooth rotation, noticeable wear and any possible damage. The burner flame should increase smoothly as the valve is opened (highest setting) and decrease smoothly as the valve is being closed. When inspecting valves, always apply a light amount of valve grease at the base of the valve stem. See grease does improve rotation of the valve, or damage is found, replace the control valve as outlined under CONTROL VALVES (36RB/C36RB) or CONTROL VALVES (36IRB/C36IRB).

SYMPTOM POSSIBLE CAUSE
1. Orifice incorrect size or dirty.
2. Incorrect gas pressure.
3. Incorrect gas type.
Flame not orange.
Burner not lighting properly or incorrect burner flame appearance due to clogged ports.
4. Orifice not aligned properely in venturi.
5. Appliance not venting properly.
6. Clogged burner ports.
7. Burner malfunction.
1. Broiler with Infrared burner is mounted too close to a fryer or charbroiler and the grease laden air is causing burner ports to clog. If burner ports are found to be clogged, install a replacement burner.
NOTE: Grease laden air is detrimental to the life of the Infrared burner. If a technician sees a broiler with Infrared burner mounted in a location close to a fryer or charbroiler, please recommend to the customer to move the broiler away from the grease laden air source to prolong the life of the Infrared burner.
