VTEC GAS INFRARED CHARBROILER PARTS AND SERVICE
SERVICE
INTRODUCTION
This manual is prepared for the use of trained service technicians and should only be used by those
who are properly qualified. This manual is not intended to be all encompassing. You should read, in its
entirety, the repair procedure you wish to perform to determine if you have the necessary tools,
instruments and skills required to perform the procedure. Procedures for which you do not have the
necessary tools, instruments and skills should not be attempted.
Procedures in this manual will apply to all VTEC models unless specified. Pictures and illustrations can
be of any model unless the picture or illustration needs to be model specific.
INSTALLATION
Generally, installations are made by the dealer or contracted by the dealer or owner. Detailed
installation instructions are included in the Installation and Operation Manual that is sent with each unit.
However, it should be noted that an improperly installed unit, can lead to premature component failures
and poor performance. All VTEC models must be installed with an externally mounted regulator.
OPERATION
Detailed operation instructions are included in the Installation & Operation Manual sent with each unit
and are also available at www.vulcanequipment.com .
CLEANING
Detailed cleaning procedures are included in the Installation & Operation manual sent with each unit.
All places where oil, grease or food can accumulate must be kept clean at all times.
LUBRICATION
All valves, at the first sign of sticking, should be lubricated by a trained technician using
high temperature grease. Frequency will be largely dependent on customer usage.
SPECIFICATIONS
All VTEC models are equipped with rotary, piezo spark igniters and 22,000 BTU/HR burners as
standard equipment. One burner is used for every 12 inches of broiling surface. The VTEC does not
utilize pilots; the burners ignite directly from the peizo igniters or manually via an outside ignition
source. Natural gas models are to operate at 4.0" W.C. manifold pressure and LP models at 10.0" W.C.
manifold pressure with all burners on.

VTEC GAS INFRARED CHARBROILER PARTS AND SERVICE
The charbroiler and its parts are hot. Use care when operating,
cleaning or servicing the charbroiler.
Shut off the gas supply before servicing the unit.
GAS PRESSURE MEASUREMENT
1. Turn the main gas shut-off valve and the
individual burner control knobs to the OFF
position.
2. Remove crumb tray. Remove pressure tap plug
underneath manifold pipe at right. Fig. 1.
3. Attach manometer at pressure tap point.
4. Turn main gas shut-off ON ,Ignite all burners
and leave on MAX setting while checking gas
pressure. See I&O Manual F-38330.
5. Turn all the equipment on the same supply line
on.
6. Gas pressure should be 4” W.C for natural gas
units and 10” W.C. for LP gas units.
7. Turn the main gas shut-off valve and the
individual burner control knobs to the OFF
position (clockwise until stops).
8. Disconnect manometer and reinstall pressure
tap plug and crumb tray.
Pressure tap
Fig. 1
All gas supply connections and any pipe joint compound must be resistant to
the action of propane gases.
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
GAS PRESSURE REGULATOR
A gas pressure regulator is supplied with the charbroiler and should be set at 4” Water
Column (W.C.) for natural gas, and 10” W.C. for propane gas. Minor adjustments may be
required based on site specific gas pressure.
The regulator should be installed as close to the charbroiler on the gas supply line as
possible. Make sure that the arrow on the underside of the regulator is oriented in the
- 7 -
VTEC GAS INFRARED CHARBROILER PARTS AND SERVICE
direction of gas flow to the broiler (Fig. 3) and the regulator is positioned with the vent
limiter and adjustment screw cover upright (Fig. 4). The vent limiter should be kept free
of grease and debris to prevent clogging and poor performance.
Adjustment coverVent limiter
Fig. 3
The minimum supply pressure (upstream of the regulator) should be 7-9” W.C. for natural
gas and 11-12” W.C. for propane gas. At no time should the charbroiler be connected to
supply pressure greater than ½ psig (3.45 kPa) or 14” W.C.
GAS PRESSURE REGULATOR ADJUSTMENT
1. Remove adjustment cover. See Fig. 4.
2. Turn the adjustment screw clockwise to increase pressure and counterclockwise to decrease
pressure.
3. Reinstall adjustment cover.
BURNER VALVE REPLACEMENT
Shut off the gas supply before servicing the unit.
Fig. 4
1.
Turn the main gas shut-off valve and the
individual burner control knobs to the OFF
position.
2. Remove inner shield assembly, knobs, shelf and
front panel.
3. Disconnect all igniter wires at the igniter
electrodes.
4. Remove all burner orifices. Fig 5.

j
5. Remove manifold retaining screw at back of
unit. Fig. 6.
6. Remove manifold assembly from unit. Fig 7.
7. Measure distance between manifold pipe and
valve to reference for reassembly later.
8. Unthread orifice extension and burner valve from
manifold.
9. Reverse steps to reinstall burner valve. The
distance between the burner valve and manifold
should match previous dimensions so that the
burner valve outlet is centered in the burner
venturi. The gap between the orifice and the end
of the burner venturi should be no more than ¼”.
Refer to Fig. 8 for correct burner valve and
orifice positioning.
All gas supply connections and
any pipe joint compound must be resistant to
the action of propane gases.
Remove screw

Prior to lighting, check all
oints in the gas supply line for leaks.
Use soap and water solution. Do not use
an open flame.
BURNER BOX ASSEMBLY REPLACEMENT
before servicing the unit.
1.
Turn the main gas shut-off valve and the
individual burner control knobs to the OFF
position.
2. Remove inner shield assembly, emitter panel,
grate and shelf.
