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.
Before connecting new pipe to the Miraclean
the pipe must be blown out to remove all foreign parti-
cles. These particles in the controls or burners may
cause improper or dangerous operating conditions.
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 com-
pound 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 pip-
ing 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 caus-
ing a hazardous condition.
WARNING
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).
Do not use
open flame
The required gas pressure for proper
to check for leaks.
operation of each Miraclean
is 4" water column for natural gas and 10" water col-
umn 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 DIS-
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
® Griddle Disconnect devices for Use with Gas Fuel, CAN1-6.9.

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 recom-
mended on any caster. The same procedure should be
followed to level the Miraclean
back.
