INSTALLATION

Shut off the range gas supply valve before removing 

the old range and leave it off until the new hook-up 

has been completed.
Because hard piping restricts movement of the range, 

the use of a CSA International-certified flexible metal 

appliance connector should be used unless local 

codes require a hard-piped connection.
A manual valve shall be installed in an accessible 

location in the gas piping external to the appliance 

for the purpose of turning on or shutting off gas to the 

appliance.
Never reuse an old connector when installing a new 

range.
To protect against gas leaks, use a qualified pipe joint 

sealant on all external threads.

NPT internal thread at the inlet of the pressure 

regulator. Use a backup wrench on the pressure

Connect a flexible metal appliance connector to 

the adapter on the range. Position the range to 

permit connection at the shut-off valve.

When all connections have been made, be sure 

all range controls are in the 

Off position and turn 

on the main gas supply valve. Gas leaks may 

occur in your system and create a hazard. Gas 

leaks may not be detected by smell alone.
Check all gas connection joints and fittings for 

leaks with a non-corrosive leak detection fluid, 

then wipe off.
Gas suppliers recommend you purchase and 

install a UL approved gas detector. Install 

and use in accordance with the installation 

instructions.

Do not use a flame to check for gas leaks.
