“T” gas connections can be installed whenever necessary for increased gas supply.
For further details, consult your gas company. -
Align the front edge of the ranges and adjust the legs to bring the manifolds together inline for connection. Clamps may be used to pull the ranges together.
-
Connect the unions between the gas manifolds.
-
Use the battery clip at the back of the range base to hold the units together.
-
Before replacing the manifold covers, check all gas connections for leaks. (See GAS CONNECTIONS in this manual. )
If the appliance has a rear gas connection, carefully check for open gas
lines.
The gas pressure regulator must have proper outlet pressure capacity for this
battery application.
GAS CONNECTIONS
NOTICE All gas supply connections and any pipe joint compound used must
be resistant to the action of propane gases.
This appliance must be connected with a gas supply line as large or larger ID
(net inside diameter) than the gas pipe inlet provided on the rear of the
appliance. Connect the gas supply to the range(s). Make sure the pipes are
clean and free of obstructions, dirt, and piping compound.
Codes require that a gas shutoff valve be installed in the gas line ahead of
the range(s).
An external gas pressure regulator must be installed on the unit at the time of installation. The regulator must be listed by a nationally recognized testing agency. These appliances are rated at the following pressure: Natural Gas – 6″ W.C. (Water Column) (1.25 kPa); Propane Gas – 10″ W.C. (2.49 kPa).
Prior to lighting, check all joints in the gas supply line for leaks.
Use soap and water solution. Do not use an open flame.
A. Check all joints prior to the gas valve (solenoid) before lighting the
unit.
B. Check all joints beyond the gas valve (solenoid) after the unit is
lit.
After the piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When test pressures exceed 1/2 psig (3.45 kPa), the range and its individual
shutoff valve must be disconnected from the gas supply piping system.
When test pressures are 1/2 psig (3.45 kPa) or less, the range must be
isolated from the gas supply system by closing its individual manual shutoff
valve.
FLUE CONNECTIONS
DO NOT obstruct the flow of flue gases from the flue duct located on the rear
of the range. It is recommended that the flue gases be ventilated to the
outside of the building through a ventilation system installed by qualified
personnel.
A minimum of 18″ (457 mm) must be maintained between the ventilation system
and the cooking surface.
Information on the construction and installation of ventilating hoods may be
obtained from the standard for ” Vapor Removal from Cooking Equipment,” NFPA
No. 96 (latest edition), available from the National Fire Protection
Association, Batterymarch Park, Quincy, MA 02169-7471.
ELECTRICAL CONNECTIONS
Electrical and grounding connections must comply with the applicable portions of the national electrical code and/or other local electrical codes.
Appliances equipped with a flexible electric supply cord are provided with a three-prong grounding plug. It is imperative that this plug be connected properly to a properly grounded three-prong receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from this plug.

OPERATION
The range and its parts are hot. Use care when operating, cleaning, or servicing the range.
BEFORE FIRST USE
Griddle Tops: Before using your griddle, the protective coating that was applied at the factory must be completely removed with a commercial degreaser. After a thorough cleaning, apply a high-temperature, salt-free frying oil and you are ready to use the griddle.
The griddle requires no “breaking-in” or “seasoning”.
OPERATING SUGGESTIONS
Standard Oven: If you have a standard oven, use your normal recipe times and
temperatures.
Convection Oven: The convection oven does everything a regular oven can do,
but with less energy consumption. The oven pre-heats faster, and baking time,
temperature settings, and shrinkage are reduced.
In general, reduce temperature to 25°F (10°C) from conventional recipes.
Check the product at half the time of the regular recipe.
Level pans bake more evenly; warped pans will give uneven baking results.
CLEANING
Turn off the gas supply to the machine.
Disconnect the electrical power and follow lockout/tag-out procedures.
Open Top Burners
Daily
Remove grates and clean under and around open burners.
1. Clean the bottom drip pan. To remove the drip pan, reach under and lift
the rear of the pan about 1″ (25 mm), slide the pan to the rear about 1/2″ (13
mm), and drop the front end of the pan free. Slide pan forward between the
front legs. To replace the pan, reverse this procedure.
Weekly
- Clean each burner thoroughly. Clean stainless steel or chromed surfaces with a damp cloth and polish with a soft dry cloth. A detergent may be used for cleaning. To remove discolorations, use a non-abrasive cleaner, always rubbing with the grain of the metal.
- Burner air shutter openings must be kept clean.
- Main burner ports and throats must be thoroughly cleaned. Venturi must be free from grease and lint. To clean burners, run through a dishwasher. Stand on the air shutter end to air dry.
DO NOT insert pick in burner port hole.
Griddle Top
Empty grease daily. Clean the griddle top regularly.
KEEP THE GRIDDLE PLATE SURFACE CLEAN. To produce evenly cooked, browned products, keep the griddle free of carbonized grease. Carbonized grease on the surface hinders the transfer of heat from the griddle surface to food. This results in spotty browning and loss of cooking ciency, and carbonized grease tends to stick to the griddled foods, giving them a highly unsatisfactory and unappetizing appearance.
To keep the griddle clean, follow these simple instructions:
After Each Use
Clean the griddle with a wire brush or flexible spatula.
Daily
- Thoroughly clean backsplash, sides, and front. Remove the grease drawer, empty it and wash it out in the same manner as any ordinary cooking utensil.
- Clean the griddle surface thoroughly. Use a griddle stone, wire brush, or stainless steel wool on the surface. Rub with the grain of the metal while the griddle is still warm. A detergent may be used on the plate surface to help clean it, but you must ensure the detergent is thoroughly removed.
- Clean stainless surfaces with a damp cloth and polish them with a soft dry cloth. To remove discolorations, use a non-abrasive cleaner.
Exterior
Daily
Clean the exterior finish with a mild solution of soap or grease-dissolving
cleaner.
Range Tops
Daily
- Wipe the top while still warm with a soft cloth.
- Clean drip pan under burners.
Weekly
Boil open-top grates and burners in a solution of washing soda and water.
Range Ovens
Daily
Clean oven and door daily.
Do not use scouring powder on finishes. Scouring powder is extremely difficult
to remove completely.
It can build up accumulations that will damage the oven or remove corrosion-
resistant finishes.
STAINLESS STEEL
Here are a few simple cleaning procedures that have been found effective for
keeping stainless steel equipment clean, sparkling, and bright.
General Cleaning
Use ordinary soap or detergent and water for routine cleaning of stainless
steel. To prevent water spots and streaks, rinse thoroughly with warm water
and wipe dry with a soft clean cloth. The addition of a rinsing agent will
also help prevent spotting.
Fingerprints
Fingerprints are sometimes a problem on highly polished surfaces of stainless
steel. They can be minimized by applying a cleaner that will leave a thin oily
or waxy film.
To use these cleaners, simply wipe on and remove excess with a soft dry cloth.
After use, subsequent fingerprints will usually disappear when wiped lightly
with a soft cloth or with a cloth containing a little of cleaner. If the
surface is especially dirty to start, wash frst with soap or detergent and
water.
Burned-On Foods and Grease
Soaking with hot soapy water will help greatly to remove burned-on foods and
grease.
Precautions
When scraping off heavy deposits of grease or oil from stainless steel
equipment, never use ordinary steel scrapers. Particles of ordinary steel may
become embedded in, or lodge on, the surface of the stainless steel. These
will rust, causing unsightly stains and possible contamination of food. Where
it is necessary to scrape, use stainless steel, wood, plastic, or rubber
tools.
MAINTENANCE
Turn off the gas supply to the machine.
Disconnect the electrical power and follow lockout / Tagout procedures.
LUBRICATION
All moving parts must be checked for wear and lubricated. Contact your local
Vulcan authorized servicer.
All valves and controls should be lubricated by your local Vulcan authorized
servicer, using a high-temperature grease.
Motors in these convection ovens are permanently lubricated and require no
additional maintenance.
FLUE
Annually check the flue when it is cool to be sure it is free of obstructions.
