Gas Supply
The local gas authority should be consulted at the installation planning stage in order to establish the availability
of an adequate supply of gas and to ensure that the meter is adequate for the required flow rate. The pipe work
from the meter to the appliance must be an appropriate size.
All fixed (non-mobile) appliances must be fitted with an accessible upstream gas shutoff valve as a means of
isolating the appliance for emergency shut off and for servicing. A union or similar means of disconnection must
be provided between the gas-cock and the appliance.
A manually operable valve must be fitted to the gas supply to the kitchen to enable it to be isolated in an
emergency. Wherever practical, this shall be located either outside the kitchen or near an exit in a readily
accessible position.
Where it is not practical to do this, an automatic isolation valve system should be fitted which can be operated
from a readily accessible position near the exit.
In locations where the manual isolation valve is fitted or the automatic system can be reset this notice must be
posted:
“ALL DOWNSTREAM BURNER AND PILOT VALVES MUST BE TURNED OFF PRIOR TO
ATTEMPTING TO RESTORE THE SUPPLY. AFTER EXTENDED SHUT OFF, PURGE
BEFORE RESTORING GAS”
NOTE: Before assembly and connection, check gas supply.
Gas Supply Notes
1) The type of gas for which the unit is equipped is stamped on the rating plate, see locations on page 9.
Connect a unit stamped “NAT” only to natural gas and stamped “LP” only to propane gas.
2) If it is a new installation, have the gas authorities check the meter size and piping to assure that the unit
is supplied with the necessary amount of gas supply and pressure to operate the unit(s).
3) Make certain new piping and connections have been made in a clean manner and have been purged so
that piping compound, chips, etc. will not clog pilots, valves, gas regulator, or burners. Use pipe joint
compound approved for natural and liquefied petroleum gases.
4) The natural gas pressure coming into the regulator should be 7” WC or .25 psig (1.75kpa) and 5” WC
.18 psig (1.25kpa) coming out of the regulator. For liquid propane gas pressure coming into the
regulator should be 11” WC or .4 psig (2.75kpa) and 10” WC .36 psig (2.5kpa) coming out of the
regulator.

Gas Pressure Regulator
A gas pressure regulator must be installed to regulate the proper flow of gas to the appliance. The regulator must
be installed between the main gas supply line to the unit shut off valve and the appliance and must be accessible
for servicing. Proper sizing of the regulator is extremely important, check the BTU rating of the appliance or
appliances being regulated by the regulator.
NOTE: Contact the factory for regulator sizing when multiple appliances are being installed in a line up or
island suite configuration and are interconnected using the front manifold connections.
NOTE: Gas pressure should be checked when the unit is installed and all other equipment on the same line is
on. The operating gas pressure must be the same as that specified on the rating plate. If necessary,
pressure adjustment may be made at the pressure regulator.
The appliance and its individual shutoff valve must be disconnected from the gas supply piping system
during any pressure testing of that system where pressures are in excess of .5 psig (3.45kpa).
When test pressures are .5 psig (3.45kpa) or less, the appliance must be isolated from the gas
supply system by closing its individual manual shutoff valve.
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.
Ventilation Air / Flue Connections
The following notes are intended to give general guidance. For detailed recommendations, refer to the
applicable codes in the Country, State, County and City of installation.
Do not obstruct the flow of combustion and ventilation air.
Proper ventilation is critical for optimum performance. The ideal method of ventilating gas fired equipment is
the use of properly designed canopy that should extend six inches (152mm) beyond all sides of the appliance (s)
and six feet six inches (1981mm) above the floor. 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, on their web site: http://www.nfpa.org/.
A strong exhaust will create a vacuum in the room. For an exhaust vent to work properly, replacement air must
be equal to the amount of air exhausted. An imbalance between exhaust and replacement air can cause
degradation in the appliance’s performance.
All gas burners and pilots need sufficient air to operate. Large objects should not be placed in front of the
appliance(s) that would obstruct the flow of air into the front.
NOTICE: In the Commonwealth of Massachusetts all gas appliances vented by either mechanical systems
or ventilation hoods shall comply with 248 CMR interlocking requirements.

Electrical Supply (Where Applicable)
Important: This appliance must be electrically grounded in accordance with local codes, or in the absence
of local codes with the National Electrical Code.
Appliances equipped with a flexible electrical supply cord are provided with a
three-prong grounding plug. It is imperative that this plug be connected into 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.

Cleaning and Maintenance
Gas Fired Appliances
CAUTION
TO AVOID RISK OF PERSONAL INJURY, BURNS OR DAMAGING UNIT
Allow the Top surface to cool before washing or rinsing. Hot steam can cause
injury. It may also damage the burners. Care should be taken around burner
valves to prevent soap/degreaser from getting into valve body and mixing with
valve grease. If equipment has electrical power running to it disconnect power
before cleaning or servicing.
1. Shut off all burners and let them cool.
2. Disconnect the power supply to the appliance before cleaning or servicing if applicable.
3. Once you are able to lift off burner assemblies, they can be soaked in warm soapy water or sprayed with
a degreaser, brush off caked on food particles with a strong bristle brush.
4. Rinse with clean water and dry thoroughly, do not install burners wet!
5. All stainless steel surfaces can be cleaned with a degreaser, stainless steel cleaner, and oven cleaner or
warm soapy water – do not spray on (due to open flame from pilot lights) apply cleaners with sponge or
cloth, heavy soil can be removed with a plastic cleaning pad or scraper. Wipe surfaces with clean damp
cloth to remove soap/cleaning solutions and dry.
6. After cleaning burner bowl run a brush through the venturies scrapping off any soot or debris.
7. DO NOT CLENA BRASS BURNERS IN A LOW TEMPERATURE DISH WASHER.
8. DO NOT USE STEEL WOOL OR STEEL CLEANING TOOLS ON STAINLESS STEEL
SURFACES – THEY COULD LEAVE STEEL PARTICLES BEHIND IMBEDDED IN
THE SURFACE AND RUST.
9. Inspect flue for grease and debris build up periodically, a dirty or plugged flue could cause unit to not
operate properly and allow build up of soot creating an unsafe environment.
10. Remove any debris from flue opening, have a qualified technician and or cleaning service clean flue of
any excess grease.
11. At least monthly, clean around burner air mixers and orifices if lint has accumulated.
NOTE: Where necessary use stainless steel, wood, plastic or rubber tools to scrape off heavy deposits of grease
and oil from any stainless steel equipment. This will help avoid any steel particles from becoming
embedded into the stainless steel surfaces. To maintain luster of stainless steel surfaces, apply a thin
coat of stainless steel cleaner, and wipe with a clean cotton cloth. To avoid heat tint (slight oxidation
which results in darkened areas in equipments stainless steel) never use more heat on any equipment
than is absolutely necessary. Heat tint can be removed by scouring with stainless steel wool or
scouring powder. Rub in direction of polished lines.
