INTRODUCTION

Like any ne, precision built piece of equipment, your
appliance, should be given regular car and maintenance.
Periodic inspections by your local dealer or a qualied
service agent are recommended.

Rating Plate

When corresponding with the factory or your local
authorized factory service center regarding service problems
or replacement parts, be sure to refer to the particular unit
by the correct model number (including the prex and sux
letters and numbers) and the warranty serial number. The
rating plate located on the side of the control panel housing
contains this information.

INSTALLATION

The importance of proper installation of commercial
gas cooking equipment cannot be overstressed. Proper
performance of the equipment is dependent, in great part,
on the compliance of the installation with the manufacturer’s
specications. In addition compliance with the National
Fuel Gas code ANSI Z 223.1-1988/NFPA and/or Local Code is
required to assure safe and ecient operation.

In Canada, the installation and connection must comply with
CAN/CGA – B149 Installation codes and local codes where
applicable.

We suggest installation, maintenance and repairs should be
performed by your local authorized service agency listed in
your information manual pamphlet.

Location of the Oven

Appliances shall be installed in a location in which the
facilities for ventilation permit satisfactory combustion of gas
and proper venting. Appliances shall be located so as not to
interfere with proper circulation of air within the conned

does not provide the necessary air, outside air shall be
introduced.

Clearances

All burner adjustments and setting shall be made by a
qualied gas technician.

152mm) clearance from combustible construction at both
sides and rear.

Ventilation

to another and must be complied with, following are
the minimum requirements for good ventilation. Please
remember these are general recommendations or
guidelines, you may have a special conditioner problem that
will require the services of a ventilation engineer or specialist.
