gas supply piping system during any
pressure testing of that system at test
pressures in excess of 1/2 psig (3.45kPa)

(continued to next page)
The fryer must be located with provision for venting into
adequate exhaust hood or ventilation system. This is essential
to permit efficient removal of the flue gases and frying odors.
Special precaution must be taken in designing an exhaust
canopy to avoid interference with the operation of the fryer. We
recommend you consult a local ventilation or heating company
to help in designing an adequate system.
piping system by closing its manual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig
(3.45 kPa)(34.47 mbar).
• A standard 3/4 inch, black steel pipe and malleable
fittings should be used for gas service connections.
• Do not use cast iron fittings.
• Although 3/4 inch size pipe recommended, piping
should be of adequate size and installed to provide
a supply of gas sufficient to meet the maximum
demand without undue loss of pressure between the
meter and the fryer. The pressure loss in the piping
system should not exceed 0.3 inch water column
(0.747 mbar).
Provisions should be made for moving the fryer for cleaning and
servicing. This may be accomplished by:
1.
Installing a manual gas shutoff valve and disconnect union, or
2.
Installing a heavy-duty (min. 3/4 inch) design A.G.A.
certified connector which complies with standard connectors
for moveable gas appliances. ANSI Z21.69 or CAN/CSA
6.16. Also, a quick-disconnect coupling which complies
with the Standard for Quick-Disconnect Devices for use
with Gas Fuel, ANSI Z21.41 or CAN 1-6.9. Also, adequate
means must be provided to limit the movement of the fryer
without depending on the connector and any quick-disconnect
device or its associated piping to limit the fryer movement.
