GENERAL

INTRODUCTION

This manual is for the Vulcan V-Series Gas Broilers
which include the double deck broiler models and the
single broiler over the Heavy Duty Range (HDR)
models. Procedures in this manual will apply to all
models unless specified. Pictures and illustrations will
be of model VIB2 - Infrared Broiler over Ceramic­Radiant Broiler 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.

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 information on rack position and gas setting, refer
to F38215 V-Series Heavy Duty range (HDR) Broilers
Operations manual sent with each unit. The manual is
also available online at www.vulcanequipment.com.

AND ADJUSTMENTS

SERVICE PROCEDURES AND ADJUSTMENTS

PILOT FLAME HEIGHT

1. Locate the pilot adjustment screws below the
burner control knobs (one on each side) on the
front of broiler. It is not necessary to remove the
control valve cover as the adjustment access
holes are provided in the panel.

Fig. 25

2. Locate the pilots at the top of the broiler heating
area.

To correct this condition, loosen the shutter screw Fig.
26 and rotate the air shutter Fig. 27 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 port. A white-blue flame is a result of
excessive primary air.

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

Fig. 26

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.
Approximate pilot flame height:

A. Ceramic-Radiant Burner - 1/2" bubble

extending from the end of pilot tube.

B. Infrared Burner - 3/4" from each side of the

pilot tee.

4. If adjustment is necessary, rotate the screw
clockwise to decrease and counterclockwise to
increase flame height.

CERAMIC-RADIANT BURNER AIR

SHUTTER ADJUSTMENT

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.

Fig. 27

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 7-14" 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

F45548 (0715) Page 12 of 16

V-SERIES HEAVY DUTY BROILERS, DOUBLE DECK AND RANGE MATCH MODELS - SERVICE PROCEDURES

AND ADJUSTMENTS

mounted in the horizontal position with the arrow
pointing in the direction of gas flow. See GAS
PRESSURE REGULATOR under REMOVAL AND
REPLACEMENT OF PARTS.

See data plate for manifold pressure setting
information. Clean vent cap [1] Fig. 28 before
adjusting.

Fig. 29

B. Insert a flat edge screwdriver through the

top of the regulator. While watching the
manometer, turn the adjusting screw
clockwise to increase pressure and
counterclockwise to decrease pressure until
the proper gas pressure is achieved.

Fig. 28

1. Connect manometer to measure gas manifold
pressure.

A. Install a tee with hose barb connection on

the outlet side of the regulator. See
TOOLS. Connect the opposite end of tee to
the incoming gas supply for the machine.

2. Turn gas supply on and light all pilots on the
machine.

3. Open all valves to the full on position to light
burners and check manometer reading. The
reading should be 6" 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 [1] Fig.

29.

C. Install the regulator closing nut.

D. Turn gas supply off.

E. Remove manometer and tee from gas line.

Clean pipe threads and apply thread

sealant that is suitable for use with propane gases.

F. Apply thread sealant to gas line pipe threads

and re-install regulator.

INFRARED BURNER ADJUSTMENT

The only adjustment for the Infrared burner is the gas
manifold pressure. Verify the pressure is set correctly
as outlined under REGULATOR ADJUSTMENT.

INFRARED BURNER FLAME

APPEARANCE

When the Infrared 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 Infrared 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.

GAS ORIFICE CHECK

If burner operation seems poor and other systems
have been checked, remove MANIFOLD COVER to
access the gas and air inlet for the Ceramic-Radiant

V-SERIES HEAVY DUTY BROILERS, DOUBLE DECK AND RANGE MATCH MODELS - SERVICE PROCEDURES

AND ADJUSTMENTS

burner Fig. 30 or Infrared burner Fig. 31. Inspect the
following:

• 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.

Ceramic-Radiant Burner Orifice

the valve is being closed. When inspecting valve,
always apply a light amount of valve grease at the
base of the valve stem. See LUBRICATION. If valve
grease does not improve rotation of the valve, or
damage is found, replace the CONTROL VALVE as
outlined under REMOVAL AND REPLACEMENT OF
PARTS.

RACK SPRING TENSION

ADJUSTMENT

1. Raise the rack lift assembly to its highest position
on stop bracket to relieve spring tension.

2. Access spring tension adjusting nuts from the
front of broiler.

Fig. 30

Infrared Burner Orifice

Fig. 31

CONTROL VALVE

Shut off the gas before servicing the

unit.

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

Fig. 32

3. Tighten nut [1] to adjust rack spring tension.
Adjust both springs equally so there is
approximately 5/8" of thread above the nut.
Spring tension is properly adjusted when the rack
assembly can be comfortably raised and lowered
by the operator using one hand.

Fig. 33

4. If additional rack spring tension is required,
tighten each nut an additional 2-3 turns and re­check.

5. Check for proper operation.

INFRARED 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.

INFRARED BURNER

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.

Tiles falling out of the burner.

4. Orifice not aligned properly in venturi.

5. Appliance not venting properly.

6. Clogged burner ports.

7. Burner malfunction.

1. Broiler with Infrared burner is located 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.
See NOTE at top of page.

1. Burner ports are clogged from the broiler operating
too close to a fryer or charbroiler that is creating
grease laden air. Clogged burner ports create poor
burner performance and cause the burner housing
to overheat and warp allowing the tiles to fall out of
burner. If tiles are missing, install a replacement
burner. See NOTE at top of page.
