pressure at the burner manifold will be low.
This may cause slow recovery and delayed
ignition. The incoming gas supply line should
be a minimum of 1½" (38 mm) in diameter.
Refer to the chart below for the minimum
sizes of connection piping.
Gas Connection Pipe Sizes (I.D.)
(Minimum incoming pipe size should be 1 1/2" (38 mm))
Gas Single Unit
3/4" (19 mm)
Natural
Propane 1/2" (13 mm)
Manufactured 1" (25 mm)
* For distances of more than 20 feet (6 m) and/or
more than 4 fittings or elbows, increase the con-
nection by one pipe size.
Before connecting new pipe to your unit, the
pipe must be thoroughly blown out to remove
any foreign particles. If these foreign particles
get into the burner and controls, they will
cause improper and sometimes dangerous op-
eration.
1. Connect the fryer gas line, located at the left rear of the unit, to the building
gas line. Use a very small amount of pipe thread compound on male threads only.
Use a compound that is not affected by the chemical action of LP gases (Loctite
PST56765 Sealant is one such compound). DO NOT apply compound to the first
two threads. This will ensure that the burner orifices and control valve do not
become clogged.
2. Open the gas supply to the fryer and check
all piping, fittings, and gas connections for
leaks. A soap solution should be used for
this purpose.

3. Close the fryer drain valve and fill the fry-
pot with water and boil-out solution to the
bottom OIL-LEVEL line at the rear of the
frypot. Light the fryer and perform the
boil-out procedures that are described in
the "Lighting Instructions" and "Boiling
Out the Frypot" topics found in Chapter 3
of this manual.
"Dry-firing" your unit will cause
damage to the frypot. Always ensure
that melted shortening, cooking oil, or
water and boil-out solution is in the
frypot before firing your unit for any
extended period.
