- CAN/CSA-B149.2 Propane Installation Code (latest edition), available from the Canadian Gas Association, 178 Rexdale Blvd., Etobicoke, Ontario, Canada M9W 1R3.
LOCATION – GAS STEAMERS
The equipment area must be kept free and clear of combustible substances.
The recommended clearance for proper operation is 36″ (914 mm) at the front.
The required clearance from combustible or noncombustible construction is 0″
at the sides and back. The recommended clearance for service access is 18″
(457 mm) at the sides and 6″ (152 mm) from the back.
Make sure there is an adequate supply of air in the room to replace air taken
out by the ventilating system. If you have any questions, contact the
ventilation system installer.
An exhaust system should be located directly above the steamer to exhaust
steam, flue exhaust and heat generated by the steamer.
Do not locate the steamer directly over a drain.
LEVELING AND ANCHORING
Position the steamer in its final installed location. Place a level on the
horizontal area of the cabinet. Adjust the feet to level the steamer in both
the left-to-right and front-to-rear directions.
Steamers should be elevated in the front just enough, about 1/16″ to 1/8″ (2
to 3 mm), to provide proper draining. Do this by rotating the adjustable feet
in the proper direction 1 to 11/2 turns after leveling. Check drainage in the
steamer compartments by pouring a small amount of water in the compartment.
All the water should drain.
The feet have holes in the flanges for anchor bolts.
PLUMBING CONNECTIONS
Plumbing connections must comply with applicable sanitary, safety and plumbing codes.
Water Requirements
Proper water quality can improve the taste of the food prepared in the
steamer, reduce liming in the steam generator and extend equipment life. Local
water conditions vary from one location to another. Ask your municipal water
supplier for details about your local water supply prior to installation.
Presence of sediment, silica, excess chlorides or other dissolved solids may
lead to a recommendation for alternate form(s) of water treatment. Test the
water with the test strip included with the steamer. Other factors affecting
steam generation are iron content, amount of chloridation and dissolved gases.
Water Treatment
A local water treatment specialist should be consulted before installation of
steam generating equipment.
Supply Pressure| 20 psig flowing – 60
psig static
---|---
Hardness| less than 3 grains
Silica| less than 13 ppm
Total Chlorine| less than 0.5 ppm
PH range| 7 – 8
Undissolved Solids| less than 5 microns
17.1 ppm – 1 grain of hardness
If the water supply fails to meet these standards, it will be necessary to install a water conditioner on the generator water feed. The use of strainers or filters will not remove minerals from the water.
Water Supply Connection
Connect the treated cold water supply line to the 3/4″ (19 mm) (male hose
thread) inlet. Connect the untreated cold water supply line to the 3/4″ (19
mm) (male hose thread) inlet marked UNTREATED WATER.
Note: Do not over tighten water connections. Over tightening the hose
connections will damage the water valve. Turn hose connection by hand till
snug and then tighten with pliers 2/3 of a turn. Check for leaks.
Note: If water lines move during water fill valve operation then a water
hammer arrestors must be added.
A water filter system is recommended for the water supply line going to the
treated water inlet. Follow the recommendations for use and installation
instructions shipped with the water filter. If a water filter is not
installed, the steam generator warranty may be limited.
A manual shutoff valve must be provided in a convenient location near the
steamer.
Filter System
If you decide to not install a scale reducing filter system design for steam
equipment or use another manufacturer’s system other than recommended by
Vulcan, please use these guidelines.
- If you are going to delime the unit with a deliming agent recommended for a pressure steam boiler and stainless steel generators and you are on city or treated well water, you still must have a carbon block filter installed and maintained. Carbon block filters remove the chlorine and chloramines disinfectants from the water. Chlorine and chloramines will erode the boiler or steam generator and will result in a vessel failure which is not covered under warranty.
- Water feed lines to the steamer must be flushed before final connection. Particles in the water could build up in the water and steam valves or clog tubing and components that maintain the water level and pressure in the boiler or steam generator. If the water supply is not free of sediment or cloudy after several minutes of flushing, a sediment filter must be installed before use.
- If you have purchased water filter system from Vulcan, please follow the At the time of installation you must register your steamer at www.vulcanequipment.com or use the reply card supplied with your unit. You will need to register your steamer at each filter change to insure your standard and extended warranty is maintained.
Drain Connection
The 1½” NPT threaded fitting on the condenser box must be extended a minimum
of 12″ (305 mm) – maximum of 72″ (1829 mm) away from steamer base, to an open
air gap type drain. Do not reduce the 1 ½” NPT drain piping throughout its
length. Provide a suitable floor sink with a minimum depth of 12″ (305 mm).
The floor sink is NOT to be directly under the steamer and should be at a
distance so that steam vapors will not enter the steamer from underneath. The
drain should slope down away from the steamer ¼” for every foot of drain pipe
length. The drain pipe should be either iron or copper. DO NOT use PVC pipe;
PVC pipe may lose its rigidity or glue may fail.
In order to avoid any back pressure in the steamer, do not connect solidly to
any drain connection.
Temperatures in the generator can briefly reach as high as 212°F (l00°C).
Local codes may require that the temperature of drain water be no greater than
140°F (60°C). At the end of the day, when purging the generators, some
provision for lowering the water temperature must be provided by the user or
installer to meet this code requirement.
GAS SUPPLY CONNECTIONS
All gas supply connections and any pipe joint compound used must be resistant
to the action of propane gas. A ¾” NPT minimum inside diameter gas supply line
is required. If quick disconnect devices are used, make sure it is sized
properly for data plate BTU/hr. rating. Refer to quick connect supplier’s data
sheet.
Codes require that a manual gas shutoff valve be installed in the gas line
ahead of the steamer.
The gas line must be capable of delivering gas to the generator without
excessive pressure drop at the minimum rate specified on the rating plate.
- Gas Input: ¾” NPT
- Natural: 5″ _ 10.5″ W.C.
- Propane: 11″ _ 13″ W.C.
Inadequate gas supply could result in burner noise and poor burner
performance.
Refer to the instruction manual supplied with the machine for INSTALLATION
CODES AND STANDARDS and GAS CONNECTION information.
Refer to the Service Manual for a view of the Blower assembly set up for
combustion issues.
The proper sizing and installation of the gas connection is important for the
machine to operate within its design specifications. In some installations,
the gas supply may not be sufficient enough to allow all the gas equipment to
operate properly at peak loads; or when other equipment with a high BTU/hr.
input requirement is operating. The connection to the machine becomes even
more important in this type of location.
Flexible gas connectors with quick disconnect or swivel fittings (when used)
and gas connectors beyond the length necessary will reduce the BTU/hr. flow
capacity to the machine.
Note: Do not use corrugated stainless steel tubing for commercial gas
equipment supply connections.
Note: A straight gas connection is the ideal condition for the rated
BTU/hr. flow capacity of the connector. If a straight connection is not
possible and a flexible gas connector is used, do not twist, kink or
excessively flex the connector beyond a U shape. Flexing the gas connector as
described will restrict gas flow or may damage the connector.
The generator is equipped with a factory preset pressure regulator. Natural gas pressure regulators are preset for 5.0″ W.C. (0.62 kPa). Propane gas pressure regulators are preset for 11″ W.C. (2.46 kPa). No further adjustment should be required. Check gas pressures with a manometer at time of installation to verify that they agree with the pressures specified.

- A. Check all joints prior to the gas valve (solenoid) before lighting unit.
- B. Check all joints beyond gas valve (solenoid) after unit is lit.
After piping has been checked for leaks, all piping receiving gas should be
fully purged to remove air.
Testing the Gas Supply System
When the gas supply pressure exceeds 1/2 psig (3.45 kPa), the steamer and its
individual manual gas shutoff valve must be disconnected from the gas supply
piping system.
When the gas supply pressure is ½ psig (3.45 kPa) or less, the steamer should
be isolated from the gas supply system by closing its individual manual gas
shutoff valve.
FLUE GAS EXHAUST
DO NOT obstruct the flow of flue gases from the flue located on the rear of
the steamer. It is recommended that the flue gases be vented to the outside of
the building through a ventilation system installed by qualified personnel.
Information on the construction and installation of ventilating hoods may be
obtained from Vapor Removal from Cooking Equipment, NFPA-96 (latest edition)
available from the National Fire Protection Association, Batterymarch Park,
Quincy, MA 02269.
ELECTRICAL CONNECTIONS
Appliances equipped with a flexible electric supply cord are provided with a
three-prong grounding plug. It is imperative that this plug be connected into
a properly grounded threeprong receptacle. If the receptacle is not the proper
grounding type, contact an electrician. Do not remove the grounding prong from
this plug.
Electrical and grounding connections must comply with the applicable portions
of the national electrical code and/or other local electrical codes.

STAINLESS STEEL EQUIPMENT CARE AND LEANING
(Supplied courtesy of NAFEM. For more information, visit their web site at www.nafem.org)
Contrary to popular belief, stainless steels ARE suscep-tible to rusting.
Corrosion on metals is everywhere. It is recognized quickly on iron and steel
as unsightly yellow/orange rust. Such metals are called “active” because they
actively corrode in a natural environment when their atoms combine with oxygen
to form rust.
Stainless steels are passive metals because they contain other metals, like
chromium, nickel and manganese that stabilize the atoms. 400 series stainless
steels are called ferritic, contain chromium, and are magnetic; 300 series
stainless steels are called austenitic, contain chromium and nickel; and 200
series stainless, also austenitic, contains manganese, nitrogen and carbon.
Austenitic types of stainless are not magnetic, and generally provide greater
resistance to corrosion than ferritic types.
With 12-30 percent chromium, an invisible passive film covers the steel’s
surface acting as a shield against corrosion. As long as the film is intact
and not broken or contaminated, the metal is passive and stain-less. If the
passive film of stainless steel has been broken, equipment starts to corrode.
At its end, it rusts.
Enemies of Stainless Steel
There are three basic things which can break down stainless steel’s passivity
layer and allow corrosion to occur.
- Mechanical abrasion
- Deposits and water
- Chlorides
Mechanical abrasion means those things that will scratch a steel surface.
Steel pads, wire brushes and scrapers are prime examples.
Water comes out of the faucet in varying degrees of hardness. Depending on
what part of the country you live in, you may have hard or soft water. Hard
water may leave spots, and when heated leave deposits behind that if left to
sit, will break down the passive layer and rust stainless steel. Other
deposits from food preparation and service must be properly removed.
Chlorides are found nearly everywhere. They are in water, food and table salt.
One of the worst chloride perpetrators can come from household and industrial
cleaners.
So what does all this mean? Don’t Despair!
Here are a few steps that can help prevent stainless steel rust.
-
Use the proper tools.
When cleaning stainless steel products, use non-abrasive tools. Soft cloths and plastic scouring pads will not harm steel’s passive layer. Stainless steel pads also can be used but the scrubbing motion must be in the direction of the manufacturers’ polishing marks. -
Clean with the polish lines.
Some stainless steel comes with visible polishing lines or “grain.” When visible lines are present, always scrub in a motion parallel to the lines. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad. -
Use alkaline, alkaline chlorinated or non-chloride containing cleaners.
While many traditional cleaners are loaded with chlorides, the industry is providing an ever-increasing choice of non-chloride cleaners. If you are not sure of chloride content in the cleaner used, contact your cleaner supplier. If your present cleaner contains chlorides, ask your supplier if they have an alternative. Avoid cleaners containing quaternary salts; it also can attack stainless steel and cause pitting and rusting. -
Treat your water.
Though this is not always practical, softening hard water can do much to reduce deposits. There are certain filters that can be installed to remove distasteful and corrosive elements. To insure proper water treatment, call a treatment specialist. -
Keep your food equipment clean.
Use alkaline, alkaline chlorinated or non-chloride cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides have a similar effect. -
Rinse, rinse, rinse.
If chlorinated cleaners are used, rinse and wipe equipment and supplies dry immediately. The sooner you wipe off standing water, especially when it contains cleaning agents, the better. After wiping equipment down, allow it to air dry; oxygen helps maintain the stainless steel’s passivity film. -
Never use hydrochloric acid (muriatic acid) on stainless steel.
-
Regularly restore/passivate stainless steel.

Review
- Stainless steels rust when passivity (film-shield) breaks down as a result of scrapes, scratches, deposits and chlorides.
- Stainless steel rust starts with pits and cracks.
- Use the proper tools. Do not use steel pads, wire brushes or scrapers to clean stainless steel.
- Use non-chlorinated cleaners at recommended concentrations. Use only chloride free cleaners.
- Soften your water. Use filters and softeners whenever possible.
- Wipe off cleaning agent(s) and standing water as soon as possible. Prolonged contact causes eventual problems.
To learn more about chloride-stress corrosion and how to prevent it, contact
the equipment manufacturer or cleaning materials supplier.

laboratory.
CLEANING
Disconnect the electrical power to the machine and follow lockout/tagout procedures before cleaning.
Cooking Compartment Drain
Keep compartment drains running freely. Inspect compartment drains daily for
blockage. Remove any particles or debris from the perforated strainer daily
(or more often if needed).
After cooking greasy foods or seafood, close the doors and operate each
compartment for 25 to 30 minutes to flush any residual grease and oils down
the compartment drain. Make a solution of warm water and non-
chloride/chlorine/bleach based detergent and pour 1/2 gallon (1.9 liters) of
it down each compartment drain. Rinse by pouring 1/2 gallon (1.9 liters) of
hot water down each compartment drain.
Draining Generator
To prevent malfunction of controls and clogging, it is essential to drain the
generator every day. This will flush out any accumulated minerals from the
feed water. It will also aid in preventing internal scale buildup which would
interfere with proper generator operation. Failure to drain the generator
every day will void the steamer warranty. The presence of minerals in
suspension is indicated by a murky or milky condition in the first portion of
the water drained.
WARNING
The water being drained is hot and under pressure. Use care when cleaning or
servicing the generator.
After the generator has been in operation, turn the unit off with the power
switch located on bottom cooking cavity to drain the generator. The generator
will drain for approximately 15 minutes, removing sediment, scale and lime
buildup in the generator.

Wash the inside of the compartment with a solution of warm water and non-
chloride detergent. Rinse with warm water.
Once a week, thoroughly clean the exposed surfaces (sides, front, door and
top) with a damp cloth and polish with a clean cloth. To remove
discolorations, use a nonabrasive cleaner.
Door Gaskets
Clean the gasket sealing surface of the compartment door daily to remove food
acids for maximum gasket life. Do not use any solvents or sharp instruments.
Wash with a cloth moistened in a solution of mild detergent and warm water.
Rinse with a fresh cloth moistened with warm water to remove all traces of
detergent.
Wipe dry with a clean cloth. Never apply food oils or petroleum lubricants
directly to the door gasket. Petroleum-based solvents and lubricants will
reduce gasket life.
LEAVE COMPARTMENT DOOR OPEN
Leave the compartment door slightly open when the steamer is not in use. When
the compartment is idle, never latch the door and apply pressure to the door
gasket. Leaving the gasket under pressure can cause permanent deformation and
reduce gasket life.
GUIDELINES FOR MAINTAINING STAINLESS STEEL SURFACES
There are four things that will break down stainless steel and allow corrosion
to develop: 1) abrasion, 2) deposits, 3) water and 4) chlorides.Avoid rubbing
with steel pads, wire brushes or scrapers that can leave iron deposits on
stainless steel. Instead, use plastic scouring pads or soft cloths. For
stubborn stains, use products such as Cameo™, talc or Zud First Impression™.
Always rub parallel to the polish lines or with the grain.
Hard water will leave deposits that promote rust on stainless steel. Treated
water from softeners or certain filters can eliminate these mineral deposits.
Other deposits from food or lubrication must be properly removed by cleaning.
Use mild detergent and non-chloride/chlorine/bleach based cleaners. Rinse
thoroughly and wipe dry. Where appropriate, apply a polish recommended for
stainless steel (such as Benefit™ or Super Sheen™) for extra protection and
luster.
MAINTENANCE
The steamer and its parts are hot. Use care when operating, cleaning or servicing the steamer.
Water Treatment System
A water treatment system is recommended for steamers. Refer to your supplier’s
manual for normal maintenance procedures for proper scale-free operation
recommendations.
Scale Related Maintenance
Periodic maintenance is necessary to keep your generator clean and efficient.
Initially, after three months of steamer usage, it is recommended that you
have your Vulcan authorized service inspect the generator. Local water
conditions and steamer usage will determine the frequency that this service
must be repeated; however, a minimum recommendation is once a year. This
maintenance is not covered by warranty.
Draining Generator
At least once daily, turn the unit off with the power switch located on bottom
cooking cavity, to drain the generator
Note: DO NOT remove the electric supply or the unit will not drain.
Door Gaskets
If the door gasket is leaking due to a nick or cut, it must be replaced.
Damage to the gasket sealing surface will cause steam leakage.
Flue
Annually (at minimum), when the steamer is cool, check the flue and clear any
obstructions.

COOKING HINTS
Where possible, spread food out evenly in pans. Do not allow food to protrude
above pans, since this will interfere with steam circulation between pans in
the compartment.
Always preheat compartments for satisfactory results.
When time does not allow for defrosting of frozen vegetables, such as loose-
pack peas, corn, diced carrots, etc., they may be cooked at once provided just
half of the suggested portions in the cooking chart are used.
