GAS CONNECTIONS AND PIPE SIZE
The Miraclean® Griddle requires a standard gas pipe
size of 3/4 inch (19mm) I.D. connection. The size of the
gas supply pipe is very important if the pipe is too small
you will have low gas pressure at the Miraclean®
Griddle manifold. Low gas pressure will cause slow
recovery and/or delayed ignition. If you have a question
about gas pipe size call your local gas company.
CAUTION
Before connecting new pipe to the Miraclean® Griddle
the pipe must be blown out to remove all foreign
particles. These particles in the controls or burners may
cause improper or dangerous operating conditions.
CAUTION
Pipe joint compounds that are used on threaded joints
of appliance piping shall be resistant to the action of
liquified petroleum gases. When using pipe joint
compound do not apply to the first two threads. Use
only very small amount and only on male threads. This
will prevent clogging of burner orifices and the gas
valve. Never use compound on female threads as it
might be pushed into the gas valve.
Have your installer check for gas leaks using a soap
and water solution before operating. DO NOT USE AN
OPEN FLAME TO CHECK FOR GAS LEAKS.
1) The Miraclean® Griddle and its individual shut off
valves must be disconnected from the gas supply
piping system during any pressure testing of that
system at test pressures in excess of 1/2 psi (3.45kPa)
(13.84 in WC) High pressure can damage the gas
valve causing a hazardous condition.
2.) The appliance must be isolated
from the gas supply piping system by
closing its individual manual shutoff
valve during any pressure testing of
the gas supply piping system at test
pressures equal to or less than 1/2 psi
(3.45 kPa).
The required gas pressure for proper
operation of each Miraclean® Griddle
is 4" water column for natural gas and
10" water column for propane gas at the manifold.
If more than one gas unit is on the same supply line,
you may require a larger line. Consult your local gas
company to assure adequate volume and pressure.
Refer to serial plate for proper gas requirement for your
particular model.
FLEXIBLE GAS CONNECTORS AND QUICK
DISCONNECT DEVICES
For an appliance equipped with casters:
The installation shall be made with a connector that
complies with the Standard for Connectors for Movable
Gas Appliances, ANSI Z21.69 or the Standard for
Connectors for Moveable Gas Appliances, CAN/CGA-
1.16, and a quick disconnect device that complies with
the Standard for Quick-Disconnect Devices for Use
With Gas Fuel, ANSI Z21.41 or the Standard for Quick
Disconnect devices for Use with Gas Fuel, CAN1-6.9.
RESTRAINING DEVICES
Adequate means must be provided to
limit the movement of the appliance
without depending on the connector
and the quick-disconnect device or its
associated piping to limit the
appliance movement.
Griddle installation on stands with
caster, casters and jam nuts must be
completely tightened.
The restraint means must be attached
to the rear of the Miraclean® Griddle within 2" of the
center line and approximately 1-5/8" from the bottom of
the cabinet back to allow the restraining bolt to be
anchored to the cabinet back between the cabinet
bottom and inner liner to ensure positive support to
restrain Miraclean® Griddle movement and not depend
on the flexible gas connector, quick-disconnect or
piping to limit the Miraclean® Griddle movement.
If disconnection of the restraint is necessary, it must be
reconnected when the Miraclean® Griddle is returned
to its originally installed position.
LEVELING
The Miraclean® Griddle will operate at its highest
efficiency when properly leveled. Place a level on the
Miraclean® Griddle plate from side to side. For griddles
on legs, the bottom foot of the leg is adjustable. Turn
counterclockwise to decrease height, or clockwise to
increase height until level. For griddles on stands with
casters, the casters are adjustable by loosening the
jam nut. When the desired level is reached, tighten the
jam nut. Adjustments of more than 3/4" are not
recommended on any caster. The same procedure
should be followed to level the Miraclean® Griddle from
front to back.
