Samsung Gas Cooktop (NAK7750 Series) Installation Guide
English 17
Installation instructions
• Clear the room, building, or area of all occupants.
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas
• Immediately call your gas supplier from a neighbor’s phone. Follow the gas
supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
– Installation and service must be performed by a qualified installer, service
agency, or gas supplier.
– Do not install the cooktop without also installing the included gas regulator. Do
not use the cooktop without the regulator installed.
– Ensure that the arrow on the regulator points in the direction of the gas flow,
towards the cooktop.
– Do not apply excessive pressure when tightening gas connections and fittings.
– Test the gas lines for leaks as instructed before use. Do not use a flame to check

Never use an old connector when installing a new cooktop. If the hard-piping
method is used, you must carefully align the pipe; the cooktop cannot be moved
after the connection is made.
To prevent gas leaks, apply pipe-joint compound or wrap pipe-thread tape with
Teflon on all male (external) pipe threads.

1. Attach the gas pressure regulator (included with the cooktop) to the cooktop
pipe nipple inlet. For tight installations, the regulator may be installed upstream
from the pipe nipple, anywhere between the shut-off valve and the cooktop.
For best performance, minimize gas pressure loss by attaching the regulator as
close as possible to the cooktop gas inlet.

2. Complete connection of the gas supply to the cooktop by installing a flexible
gas line between the pressure regulator and the shut-off valve.

Step 4. Check for gas leaks.
WARNING
To prevent death, personal injury, explosion, and/or fire hazard, DO NOT use a
flame to check for gas leaks.
When using test pressures greater than ½ psig to pressure-test the gas supply
system of the residence, disconnect the cooktop and individual shut-off valve
from the gas supply piping. When using test pressures of ½ psig or less to test
the gas supply system, simply isolate the cooktop from the gas supply system by
closing the individual shut-off valve.
1. When all connections have been made, make sure all cooktop controls are in the
flame to check for gas leaks.

1. When all connections have been made, make sure all cooktop controls are in the
off position and turn on the main gas supply valve.
2. Use a liquid leak detector at all joints and connections to check for leaks in the
system.
3. Tighten all connections if necessary to prevent gas leakage in the cooktop or
supply line.
