Installation Of Appliance

This appliance was adjusted at the factory for use with
natural gas. If, at any time, this appliance is to be used
with a different type of gas, all of the conversion
adjustments must be made by a qualified service
technician before attempting to operate the cooktop on
that gas. Natural gas should be supplied to the appliance
pressure regulator at a line pressure between 6 and 14
inches of water column or, if converted for LP gas,
between 11 and 14 inches.

WARNING

If the line pressure supplying the appliance pressure
regulator exceeds 14² W.C. (any gas), an external
regulator must be installed in the gas line ahead of the
appliance regulator to reduce the pressure to no more
than 14² W.C. Failure to do this can result in malfunction
and damage to the appliance.

Insure this appliance is adjusted for the type of gas
supplied to it and that the gas supply pressure to the
appliance regulator is within the proper pressure range.

Do not remove protective cap from pipe stub at manifold
entrance until ready to join gas supply piping to appliance.

Position unit in the Countertop Cutout. Main Control Panel
should overlap top of Lower Control Panel as shown
(Figure 7).

Gas Supply Connection

A TRAINED SERVICEMAN OR GAS APPLIANCE
INSTALLER MUST MAKE THE GAS SUPPLY
CONNECTION. Leak testing of the appliance shall be
conducted by the installer according to the instructions
below.

Apply a non-corrosive leak detection fluid to all joints and
fittings in the gas connection between the supply line
shut-off valve and the range. Include gas fittings and
joints in the range if connections were disturbed during
installation. Check for leaks! Bubbles appearing around
fittings and connections will indicate a leak. If a leak
appears, turn off supply line gas shut-off valve, tighten
connections, turn on the supply line gas shut-off valve,
and retest for leaks.

CAUTION: NEVER CHECK FOR LEAKS WITH A
FLAME.

WHEN LEAK CHECK IS COMPLETE, WIPE OFF
ALL RESIDUE.

If the alternative piping method shown in figure 8 is
selected for the installation, no ground joint union is
required. (The flexible appliance connector illustrated
provides the union joints necessary for servicing.) When a
dividing wall is present and a flexible connector is used it
is recommended for convenience, in both installation and
service, the flexible connector, itself, pass through the
dividing wall. Any flexible connector used with this

appliance must satisfy all requirements stated in the
text following figure 8.

Unless prohibited by local codes or ordinances, a new
A.G.A. - Certified, flexible metal appliance connector may
be used to connect this appliance to its gas supply. The
connector must have an internal diameter not less than
nominal 1/2² NPT pipe and be no more than 5 feet in
length. A 1/2² NPT x 1/2² flare union adapter is required
at each end of the flexible connector. If a flexible
connector is used assure that both the appliance pressure
regulator and manual shut-off valve are joined solidly to
other permanent hard piping (either gas supply or the
appliance manifold) so as to be physically stationary.

CAUTION: Do not attempttoattachthe flexibleconnector
directly to an external pipe thread. Connection requires
flare union adapters.

Pressure Testing

The appliance 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 PSIG
(3.5 kPa).

This appliance, as well as its individual shut-off valve,
must be disconnected from the gas supply piping system
during any pressure testing of the system at test
pressures in excess of 1/2 PSIG (3.5 kPa).

When checking appliance regulator function, make certain
pressure of natural gas supply is between 6 and 14
inches of water column or, if converted for LP gas,
between 11 and 14 inches.

Burner Ignition And

Required Adjustments At Time

Auto-Reignition

This appliance is equipped for electronic auto-reignition by
means of a spark igniter located at the rear of each
burner. The burners are designed to light at any valve
rotation that admits sufficient gas flow to support a flame
and to automatically relight following a loss of flame due
to a draft or other adverse condition. This feature is
provided as a convenience and is not intended as a safety
feature.

This appliance has no air shutters. Primary air
adjustments are unnecessary. The burners are designed
to provide optimum aeration for all gases without air
shutters. When operating properly, burners should
produce clearly defined, even blue flames. If the flames
have yellow tips or are hazy and otherwise appear to
have insufficient air, obtain the services of a qualified
service technician.
