LEVELING
Check the leveling of the range. Place a carpenter's level inside the oven cavity across the oven rack.
Level the range from front to back and from side to side.
To adjust the leveling of the range, tilt the range to one side and, using channel locks, unscrew the
adjustable leg insert as required. Repeat this procedure as necessary for each leg.
Casters for this range are of the non-leveling type. Therefore, the floor must be level. If floor surface
is not level, the range will experience cooking problems until it is level.
GAS CONNECTIONS
CAUTION: All gas supply connections and any pipe joint compound used must be resistant to
the action of propane gases.
Each range is factory equipped for use with the type of gas specified on the range rating plate.
Connect gas supply to the range. Make sure the pipes are clean and free of obstructions.
Codes require that a gas shutoff valve be installed in the gas line ahead of the range.
Ranges are equipped with fixed burner orifices which coincide with the proper range operation
elevation.
The gas pressure regulator is NOT factory installed. The regulator for this range is sealed within a
plastic bag attached to the oven rack inside the oven. This regulator must be installed by qualified
personnel.
Before installing, check that the regulator matches the gas supply indicated on the data plate.
Natural gas regulators are preset for 3.5" W.C. (Water Column); propane gas regulators are preset for
10.0" W.C. (Water Column).
1. Locate 3/4" gas connection pipe extending from the rear of the range.
2. Cover pipe threads with pipe joint compound.
3. Screw regulator hand-tight onto the pipe with regulator arrow pointing towards range body back
(Fig. 9). The arrow on the regulator shows direction of gas flow.
4. Using pipe wrench, tighten regulator securely in an upright position (Fig. 10). The pressure
regulator must be mounted horizontally to ensure proper preset outlet pressure. If the regulator is
mounted in any other position, the outlet pressure must be reset.
The pressure regulator must be design certified and must have regulation capacity for the total
connected load. It must have a pressure adjustment range to allow adjustment for manifold pressure
marked on the range rating plate.

— 10 —
Fig. 9 Fig. 10
Unless manifold pressure on all connected appliances is the same, a separate regulator must be
supplied for all ranges having different manifold pressures.
A leak limiter is supplied with every regulator to allow excess gas pressure to escape. Do not obstruct
leak limiter on gas pressure regulator as obstruction may cause regulator to malfunction.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds 1/2psig (3.45 kPa), the range and its individual shutoff valve must
be disconnected from the gas supply piping system.
When gas supply pressure is 1/2psig (3.45 kPa) or less, the range should 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.
From the termination of the range flue vent to the filters of the hood venting system, a minimum
clearance of 18" must be maintained.

— 11 —
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 02269.
Adequate air should be provided in the kitchen to replace air taken out by the ventilating system.
Do not permit fans to blow directly at the range. Whenever possible, avoid open windows next to the
range. Avoid wall-type fans which create air cross currents within the room.
PILOT LIGHTING ADJUSTMENTS
All adjustment procedures associated with pilot lighting must be performed by a qualified Vulcan-Hart
installation or service person. The bypass (minimum burner) flame adjustment must be made at the
time of installation.

BEFORE FIRST USE
Griddle Seasoning
This griddle plate is steel, but the surface is relatively soft and can be scored or dented by the careless
use of a spatula or scraper. Be careful not to dent, scratch, or gouge the plate surface. Do not try to
knock off loose food that may be on the spatula by tapping the corner edge of the spatula on the griddle
surface.
A new griddle surface must be seasoned to do a good cooking job. The metal surface of the griddle
is porous. Food tends to get trapped in these pores and stick; therefore, it is important to "season" or
"fill up" these pores with cooking oil before cooking. Seasoning gives the surface a slick, hard finish
from which the food will release easily.

— 15 —
To season, heat griddle top section at a low burner setting. Pour one ounce of cooking oil per square
foot of surface over the griddle top section. With an insulated cloth, spread the oil over the entire griddle
surface to create a thin film. Wipe off any excess oil with an insulated cloth.
Repeat this procedure 2 to 3 times until the griddle has a slick, mirrorlike surface.
RACK ARRANGEMENTS
The Econoline Series Oven is equipped with one rack per oven section. Each oven section has two
rack positions. Proper rack positioning is to be determined by the individual cooking needs of the
operator.
OVEN LOADING AND UNLOADING
When loading the oven, open the door and load as quickly as practical to conserve heat. Take care
to avoid spilling liquids while loading. Close the door and refer to recipe for cooking time.
Provide adequate space for product unloading. Rapid unloading will conserve heat and ensure proper
preheating conditions for the next load, if applicable.
INSERTING AND REMOVING OVEN RACK
On ovens provided with oven rack stops, it is necessary to place rack, including the support hook, along
the top of the side liner runners and slide the rack completely to the rear of the oven compartment until
the rack drops into place (Fig. 13).
Fig. 13

— 16 —
To remove the rack, reverse the procedure by raising the rear of the oven rack support hooks above
the runner and pulling the rack forward (Fig. 14).
PREHEATING
Oven
Turn thermostat control to the desired cooking temperature and preheat oven for 25 minutes. The
automatic heat control will cut gas and food costs if properly used. Do not operate oven at maximum
heat when it is not necessary. Turn thermostat down to 250°F or OFF when oven is not in use or during
idle cooking periods.
Ranges (Open Top)
As these are quickly ignited, light only as many as needed.
Griddle Top Ranges
Heat top thoroughly before using. It can be kept hot with burners turned partly down. During off
periods, turn burners down or keep only half of top heated.
Broiler/Griddle Section
Before cooking on griddle plate, grease well and light burners. With minimum burner flame, allow
griddle to heat gradually. Do this the first three times the griddle is used. This will relieve stresses in
the plate and ensure long life.
Fig. 14

— 17 —
1. Turn the three burner valve knobs fully ON.
2. After preheating for 5 minutes, turn the burner valve knobs down until the desired flame or heating
level is achieved.
3. Position removable grid into one of the two slide positions, depending on which will achieve the
proper product preparation results.
CLEANING
Ranges
Wipe top daily, while still warm, with a grease absorbing cloth to remove spillovers, grease, etc., before
they burn in. A crust on top of the range looks unsightly and slows down speed of cooking because
it reduces the flow of heat to the utensil. Scrape off if necessary.
Open Top Grates and Burners
Boil weekly in a solution of washing soda and water. Clean drip pan under burners with warm soapy
water. Rinse thoroughly and wipe dry with a soft clean cloth.
Griddle Top
Cleaning griddle and fry top sections will produce evenly cooked, perfectly browned griddle products
and will keep the cooking surface free from carbonized grease. Carbonized grease on the surface
hinders the transfer of heat to the food. This results in loss of cooking efficiency and spotty browning
which gives foods an unappetizing appearance. To keep the griddle clean and operating at peak
efficiency, follow these instructions:
After Each Use
Clean griddle with a wire brush or flexible spatula.
Once A Day
Thoroughly clean backsplash, sides and front. Remove grease pan, empty, and wash out in the
same manner as any ordinary cooking utensil.
Once A Week
Clean griddle surface thoroughly. If necessary, use a griddle stone, wire brush or steel wool over
surface. Rub with grain of the metal while still warm. A detergent may be used on the plate surface
to help clean it, but make sure it is thoroughly removed. After removal of detergent, reseason the
surface of the plate with a thin film of oil to prevent food sticking. If the griddle is to be shut down
for an extended period, put a heavy coat of grease over the griddle plate.

— 18 —
Oven
Clean oven and oven door daily, especially if fruit pies or tomato sauces were baked, meats roasted,
and if there have been spillovers.
Do not use scouring powder. It is extremely difficult to remove completely, and can build up
accumulations that will damage the oven.
Remove nickel plated racks and rack supports daily and clean in a sink.
After processing some foods at low temperatures, odors may linger in the oven. These odors may be
cleared by setting the thermostat at 500°F and allowing the oven to operate unloaded for 30 to 45
minutes.
Exterior
Clean exterior finish daily with a mild grease dissolving solution.
Painted surfaces may be cleaned using a cloth and detergent solution. Rinse thoroughly and wipe dry
with a soft clean cloth.
OPERATING SUGGESTIONS
Oven
If you desire to cook high roasts, the entire height of the oven can be used by removing shelf or rack
and placing roast pan directly on insulated oven bottom.
Moderate oven temperature will produce better food, reduce shrinkage and keep upkeep costs down.
Use low temperature roasting method with oven temperature at about 325°F to cut meat costs by
reducing shrinkage.

— 19 —
MAINTENANCE
WARNING: THE RANGE AND ITS PARTS ARE HOT. BE VERY CAREFUL WHEN OPERATING,
CLEANING OR SERVICING THE RANGE.
VENT
When cool, the vent of this range should be checked every six months for obstructions.
