Important safety instructions

Installation

The minimum distances given in
these Installation Instructions must
be observed in order to ensure safe
operation. Failure to do so increases
the risk of fire.

The countertop must be bonded

with heat resistant (212 °F/100 °C)
adhesive to prevent distortion or dis
solving.

-

fig. 1 recommended

Deep fat fryers must not be in

stalled next to gas cooktops. Gas
flames can ignite splattering oil. A dis­tance of at least 12" (305 mm) should
be maintained between these two ap­pliances. The mimimum distance be­tween two cooktops must be 4"
(10 cm).

The cooktops should only be in-

stalled as shown in Figs. 1 & 2,
while maintaining the required safety
distances shown. Do not install the
cooktop between two tall cabinets as
this is a fire hazard.

a = minimum distance between
cooktop and a tall cabinet:
12" (300 mm)

Cooktops should not be installed

above a dishwasher, washer, dryer,
freezer or refrigerator. The heat gener
ated by cooktops could damage these
appliances.

Important safety instructions

Gas appliances should only be in
stalled in a well ventilated area.

Install the appliance so that the

power cord or gas piping does not
come into contact with any portion of
the cooktop which may become hot
during use.

This appliance must be installed
with its own shut off valve and the in
cluded gas pressure regulator. Both
the valve and the regulator must be
easily accessible to the consumer to
turn on or shut off the gas supply af
ter the appliance is installed.

This appliance must be discon­nected from the gas supply during
any pressure testing of that system
performed in excess of

1 / 2 psi

(3.5 kPa), or isolated at test pres­sures equal to or less than

1 / 2 psi

(3.5 kPa).

Any pipe connections must be made
using a thread sealant approved for
gas connections. Failure to correctly
install these items could lead to a
gas leak and subsequent explosion.

Safety distance above the appliances

-

-

As a general rule there must be at least
30 inches (762 mm) between the top of

­the appliance and any cabinet above it,
b. If the cabinet manufacturer recom­mends a greater distance, follow that
manufacturer’s recommendation.

The maximum depth, c, of cabinets in­stalled above a cooktop must not ex­ceed 13" (330 mm).

When installing the cooktop under a
venting hood, always observe the mini­mum safety distance recommended by
the hood manufacturer.

Keep this instruction book in a safe
place for future reference and pass it
on to any future owner.
