GAS CONVERSIONS
IMPORTANT: Gas conversions from Natural gas to Propane gas
must be done by a qualied installer.
Propane Gas Conversion
1. Turn the manual shut-off valve to the closed position.
2. Unplug cooktop or disconnect power.
To Convert Gas Pressure Regulator from Natural Gas
to Propane
1. Remove the gas pressure regulator cap by using a
large at-blade screwdriver, turning the regulator cap
counterclockwise. When the cap is removed, do not lose the
metal seal.
NOTE: Do not remove the spring beneath the cap.
2. Remove spring retainer from the cap by turning the spring
retainer counterclockwise. Locate the “LP” and “NAT”
position on the spring retainer. Turn over the spring retainer so
the “LP” arrow is pointing toward the cap.
3. Tighten the gas pressure regulator cap by using a large at
blade screwdriver, turning the regulator cap clockwise.
4. Test the gas pressure regulator and gas supply line.
The regulator must be checked at a minimum 1" (2.5 cm)
water column above the set pressure. The inlet pressure
tothe regulator should be as follows for operation and
checking the regulator setting:
Propane Gas:
Minimum pressure: 10" (25.4 cm) WCP
Maximum pressure: 14" (35.6 cm) WCP
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least 1"
(2.5 cm) water column pressure above the manifold pressure
shown on the model/serial/rating plate.
Line pressure testing above 1/2 psi (3.5 kPa) gauge (14"
[35.6cm] WCP)
The cooktop and its individual shut-off valve must be
disconnected from the gas supply piping system during
anypressure testing of that system at test pressures in
excess of 1/2 psi (3.5 kPa).
Line pressure testing at 1/2 psi (3.5 kPa) gauge (14"
[35.6cm]WCP) or lower
The cooktop must be isolated from the gas supply piping
system by closing its individual manual shut-off valve during
any pressure testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
WARNING
Explosion Hazard
Use a new CSA International approved gas supply line.
Install a shut-off valve.
Securely tighten all gas connections.
If connected to propane, have a qualified person make
sure gas pressure does not exceed 14" (36 cm) water
column.
Examples of a qualified person include:
licensed heating personnel,
authorized gas company personnel, and
authorized service personnel.
Failure to do so can result in death, explosion, or fire.
