INTRODUCTION

1.1.1 

All models

 

All models are equipped with pilot safety
system, spark enabled pilots, temperature
controls for each 12” zone, heated by two
15,000 Btu burners. Temperature sensing
probes are embedded into the plate
between each pair of burners.

 

MKG Series appliances may have suffixes
that denote the following:

 

Numerals 24, 36, 48, 60, and 72 denote
the width of the appliance in inches.

 

Suffix  “L”, “R” and “B” denote 

left, right

and rear

 grease troughs, respectively.

 

Important information located on Data Plate, See Figure 1 at right.

1.1.2 

Snap Action Models

 

Snap Action models have gas safety valves, Piezo pilot ignition systems and snap action gas
temperature controls.

 

Snap Action models have no suffix designation.

 

Snap Action models require no external electrical supply.

1.1.3 

Matchless Models

 

Letter designations represent matchless ignition (flame proving spark ignition), temperature control
options and grease chute options.

 

Suffix “E” models have flame proving spark ignition systems and electro-mechanical thermostats.
External power supply is required.

 

Suffix “ST” models have flame proving spark ignition systems with solid state temperature controls.
External power supply required.

1.2 

INSTALLATION, OPERATION AND CLEANING

 

A qualified person, in accordance with all national and local codes, must perform the installation.
