• Installation must comply with local code, or in the absence of local code, with the National Fuel Gas Code,
ANSI Z223.1/NFPA 54 [in Canada, Natural Gas and Propane Installation Code, CSA B149.1] includin :
• The appliance must be disconnected from the incoming gas supply line at the main shut-off valve, during any
testing of the piping at test pressures in excess of 1/2 psi (3.5kPa).
• The appliance must be isolated from the incoming gas supply line by closing the fryer Gas Shutoff Valve, during
any testing of the piping at test pressures equal to or less than 1/2 psi (3.5kPa).
1. Check pressure of the incoming gas supply and compare to Tab e 2.5.2. If necessary install a secondary pressure
regulator on the supply line to regulate supply pressure to a maximum of 13.85” W.C. [3.45 kPa].
2. Install an appropriate Quick-Disconnect fitting on the gas line.
3. Connect an approved 1/2” flexible gas line (not provided) between the supply line disconnect and the Fryer gas
regulator located on the rear of the unit.

IMPORTANT!
The factory-installed regulator on the fryer controls gas pressure supplied to the gas valve as shown in Table 5-
2.2. This regulator is rated for max. input pressure of 13.85” W.C. [ 3.45 kPa]. If supply line pressure exceeds
this maximum, a secondary re ulator must be installed in the supply line, upstream of the installed re ulator,
to maintain pressure at or below the maximum ratin .
