3.7 Tank cover installation – Outside Installation ONLY
Tanks installed outside must be installed with GIL-FAB Cover Assembly (P/N DWOT RC) with the fill,
vent and gauge located inside the cover. After unpacking, each cover shall be visually inspected for
“unacceptable damage”. “Unacceptable damage” is defined as cuts, dents or permanent deformation of
the structure which could cause leakage, excessive corrosion, or other mechanical and safety hazards.
Minor deformation and dents are acceptable.
For connection of the burner supply line, remove a knockout and replace with a UL Listed outdoor rated
bushing matching the pipe size to ensure a liquid-tight connection.
3.8 Multiple Tank Installations
If multiple tanks are installed:
• Each tank must be installed and piped independently from one another as a single tank
installation following these instructions;
• Cascade tank filling and combined venting are prohibited; and
• The total aggregate capacity must not exceed the limit permitted by the applicable codes and
regulations.
3.9 Tank anchoring
A tank must be anchored to its foundation if one of the following conditions exists:
• It is intended for outside installation; or
• It is installed in an area subject to earthquakes or floods.
For tank anchoring, we recommend the use of GIL-FAB Tie-Down Kit (P/N DWOT 190TDK) for Model
190 Gal and (P/N DWOT 265TDK) for Model 265 Gal. We also recommend the use of multiple tie-down
kits in high risk areas.
3.10 Testing
The tank has been factory-tested to detect any leaks.
The installer, or a person delegated by him, is to attend the first full filling of oil to verify the tank
connections seal integrity of the entire system.
3.11 Operating instructions
During normal refilling procedure:
• Do not overfill; and
• Do not fill at an excessive rate.
Always follow all applicable codes and regulations from the applicable Authority Having Jurisdiction.
