Installation Precautions

All tanks and installations must conform with all building/fire codes, all Federal, State, and 
Local codes, National Electrical Code (NFPA 70), NFPA 30, Automotive and Marine Service 
Station Code (NFPA 30A), and NFPA 395 codes and regulations.

Plan your installation carefully. Dispensing troubles, which seem to be pump-related, are 
frequently traced to faulty installation. Review the following list of installation 

DOs

 and 

DO NOTs

 to avoid potential problems:

DO

 read the 

“Important Safety Information”

 on 

page 3

. It contains important information 

regarding the safe use of fuel dispensing equipment.

DO

 have the valve installed by a qualified installer.

DO

 remove the shipping plug from the vent opening for proper operation of valve.

DO

 

NOT

 experiment with fuel dispensing equipment if you are not sure whether the 

installation is correct.

DO

 

NOT

 install any underground piping without proper swing joints. Always use 

shoulder nipples, never close nipples.

DO

 

NOT

 cover any lines until they have been both air and liquid-tested.

DO

 

NOT

 back-fill the tank or supply line with cinders or ashes. Back-fill with clean sand, 

crushed rock, or pea gravel.

DO

 

NOT

 use black iron pipe or fittings for underground installations. Use only new 

galvanized or fiberglass*

 

pipe and fittings.

requirements.

NOT

 install the fill pipe to a tank where it can be submerged with standing water.

DO

 

NOT

 use the Gasboy fuel dispensing equipment to remove water ballast from the 

storage tank.

DO

 

NOT

 use gaskets on covers of explosion-proof type boxes. The sealing compound 

found at various locations within conduit is a requirement of the National Electrical Code 
and should not be disturbed. Tighten the Junction Box covers before replacing panels.
