WARNING
If the information in this manual is not followed exactly, a fire or explosion may
result causing property damage, personal injury or death.
FOR YOUR SAFETY
Do not store or use gasoline or other flammable vapors and liquids in the vicinity
of this or any other appliance.
WHAT TO DO IF YOU SMELL GAS
•Evacuate all persons from vehicle.
•Shut off the gas supply at the gas container or source.
•Do not touch any electrical switch, or use any phone or radio in the vehicle.
•Do not start the vehicle’s engine or electrical generator.
•Contact the nearest gas supplier or qualified service technician, contact
nearest fire department.
•Do not turn on the gas supply until the gas leak(s) has been repaired.
Installation and service must be performed by a qualified installer, service agency
or the gas supplier.
FIRE HAZARD
Do not obstruct the flow of combustion and ventilation air.
PERSONAL INJURY HAZARD
To eliminate the risk of burns or fire by reaching over heated surface units,
cabinet storage space located above the surface unit should be avoided. If
cabinet space is to be provided, the risk can be reduced by installing a range
hood that projects horizontally a minimum of 5 inches beyond the bottom of the
cabinets.
Reaching over a heated cooking surface could result in a serious burn or other
personal injury.
CARBON MONOXIDE POISONING
•Do not use any cooking appliance for space heating because of potential
danger to occupants of the vehicle and damage to the cooktop.
•A window or air vent should be open slightly while using any cooking
appliance. Gas flame consumes oxygen which must be replaced to assure
proper combustion and prevent carbon monoxide.

3
Note to consumer: Have the installer or dealer show you where the main
gas shut off valve is located so that you will know how and where to turn off the
gas supply when necessary.
IMPORTANT INSTRUCTIONS
Save the Owner’s Manual / Installation instructions for local inspector’s use.
NOTE: LPG is heavier than air and if allowed to settle, accumulate and if
ignited WILL CAUSE AN EXPLOSION!!
Install cooktop, cylinder, and regulating system in compliance with ABYC A-1
“Marine LPG – Liquid Petroleum Gas Systems”. For RV applications the

CYLINDERS
Cylinders used in LPG systems shall be constructed, tested, marked, maintained
and re-qualified for continued service in accordance with DOT regulations.
No repairs or alterations shall be made on any cylinder.
Cylinders that have been subject to fire or physical damage shall not be returned
to service unless re-qualified.
LPG cylinders shall be permanently and legibly marked in a conspicuous manner
on the outside to show the correct mounting position. The method of mounting
shall be designed to position the cylinder correctly.
The cylinder shall be returned to an authorized fuel distributor for refilling.
Cylinders shipped by land or air freight must be packed and marked in
accordance with DOT regulations.
Only systems using LPG cylinders of the vapor withdrawal type are permitted.
Cylinders designed or installed so as to admit liquefied gas into any other part of
the system are prohibited.
CYLINDER VALVES AND SAFETY DEVICES
Each LPG cylinder shall have manually operated shut-off valve threaded directly
into the cylinder outlet, the valve outlet conforming to CGA connection number
510. The valve shall be equipped with a securely attached hand wheel for
convenient operation without the use of a separate wrench.
For Marine use. A readily accessible shut-off valve or electrically operated
solenoid shall be installed in the low or high pressure supply line to each
attended appliance. The valve or its control shall be operable from within the
vicinity of the appliance and its control readily accessible in the event of a fire at
the appliance. If the cylinder valve is readily accessible from the vicinity of the
attended appliance, the above shut-off valve on the supply line is not required.
All LPG cylinders shall be provided with a safety relief device specifically
designed for LPG as required by DOT regulations.
A threaded protective cap and retaining device to protect the threads of the
cylinder valve during transit and storage shall be supplied.
In addition to the valve required at the cylinder, a dual cylinder system shall be
provided with a two-way positive shut-off valve at the cylinder manifold.

5
Cylinder valves and safety relief devices shall be installed in, or be directly
connected to, the vapor space of the cylinder.
The LPG tank valve outlet fitting does not require pipe dope or Teflon tape and
should be attached to the regulation system nut dry and clean to keep foreign
materials out of the system. When assembling the regulation system, use a high
quality sealant only on all male pipe threads.
REGULATING SYSTEM
Each LPG system shall be provided with a regulating device, specifically
designed for use with LPG.
The LPG regulating device shall be adjusted to deliver gas at any or each
appliance, under varying appliance loads, at a pressure not in excess of 11
inches water column, approximately 0.397 pounds per square inch gauge.
Each regulating device shall be fitted with a high flow check valve located on the
cylinder pressure side of the regulating device. In the event of a regulator
malfunction, the high flow check valve must actuate and control gas flow through
the vent or vent system to the open atmosphere. This check valve must maintain
this gas flow within the designed pressure limits of the vent system.
For Marine use. Each regulating device shall be fitted with a 0 to 250 PSI
pressure gauge. The gauge shall read the cylinder pressure side of the
regulating device. See page 14 for general leak down procedures for RV or
Marine
NOTE: The purpose of the gauge is to provide a quick and easy way to test
the system for leakage.

LEAK CHECK & LEAK DOWN TEST
Check all connections for gas leaks with a non-corrosive and non-toxic leak
detection fluid. Test the unit by turning on the LPG tank and observing the
pressure gauge. Turn the tank valve off and note the pressure. If there is no drop
on the gauge in 3 minutes, the system is free of leaks.
Ammonia, which is present in some soaps and detergents, attacks brass fittings.
Undetectable at first, in a matter of months these fittings may develop cracks and
leaks.
WARNING
DO NOT USE OPEN FLAME TO CHECK FITTINGS AND GAS LINES FOR LEAKS.
Checking for leaks with an open flame may result in a fire or explosion.
LINE PRESSURE TEST ABOVE ½ PSI
The cook top must be disconnected from the gas supply line system during any
pressure testing in excess of 8 oz. per square inch. (1/2 psi)
TO LIGHT THE BURNERS
1. Push down the knob and turn counterclockwise to “IGNITE” position.
2. Hold the knob down fully until the spark ignites the gas and continue to
hold the knob down for approximately 5 to 10 seconds. The
thermocouple will be heated to activate the safety mechanism.
(**Does not apply to models 2277-1002 & 2277-1003 )
3. Release the knob and set to desired setting.
4. To turn off the burner flame, turn the knob clockwise to “OFF” position.
*Thermocouple is not used in models 2277-1002 & 2277-1003

13
CAUTION
•Be sure your cooktop is installed properly.
•Do not operate cooktop if it is damaged or not working properly.
•Do not store flammable materials on or near the cooktop.
•Never leave lit burners unattended. A boil-over may result, causing smoke or fire.
•Do not use your cooktop for warming or heating the room.
•The handle of utensil should be positioned so that it is turned inward but not
extending over adjacent burner.
•To reduce the risk of burns and ignition of flammable materials, the burner flame
should not extend beyond the edge of the cooking utensil.
•Grease is flammable. Never allow grease to collect around top burners or
cooktop surface. Wipe spillovers immediately.
•Only certain types of glass, glass / ceramic, earthware, or other glazed utensils
are suitable for cooktop use without breaking due to sudden change in
temperature.
•Do not use water on grease fire. Smother the fire or flame or use baking soda,
multipurpose dry chemical or foam type fire extinguisher.
•Children should not be left alone or unattended in area where cooktop is in use.
Children should never be allowed to sit or stand on any part of the cooktop.
•Do not heat unopened containers. They could explode.
•Do not touch burners, grates or areas near cooktop after use. Units may be hot
even thought it may not be obvious. Areas near burners and grates may become
hot enough to cause burns. During and after use, do not touch, or let clothing or
other flammable material contact cooktop or areas near it until they have had
sufficient time to cool.
CARE AND CLEANING
Regular cleaning with a soft cloth and a warm detergent solution is generally enough to
keep your cooktop clean and beautiful. This is done when the cooktop is cool. Use a
dry cloth or paper towel to clean splatters and spills when surfaces are warm.
GLASS
We recommend the use of HOPE’S CLEANING CREAM for care and maintenance of
the glass surfaces. For more information about this product and a dealer near you,
contact: THE HOPE COMPANY, Inc. [phone]
STAINLESS STEEL
The best way to clean metal surfaces on your stove is to wipe them down with a damp
cloth, and then dry thoroughly, stubborn spots caused by spillage and discoloration
from heat may be removed by the use of lemon juice, vinegar, or chrome polish. Care
must be used to keep these away from porcelain enamel surfaces. NEVER use coarse
cleaners, steel-wool scouring pads or metal brushes to clean chrome. These will make
deep scratches on chrome. These scratches cannot be removed.
