SECTION 6 FUEL SUPPLY TANK INSTALLATION
If using a Lanair supply tank follow instructions included with the tank.
6.1 The fuel supply tank and supply lines must be installed in accordance with
the National Fire Protection Association requirements, as well as State and
Local ordinances. See Section 2.
6.2 Regulations require oil storage tanks located inside not too exceed 275
gallons individually, and are not to exceed a total capacity of 550 gallons in
one building. Check State and Local codes.
6.3 Locate the fuel supply tank inside the building as close to the heater as
possible. It should be no further than 25 feet from the heater to avoid oil
flow problems.
6.4 The fuel supply tank must be mounted below the burner and the by-pass
regulator. Mounting the fuel supply tank above the burner will create head
pressure and overfire the burner voiding the warranty.
6.5 Pitch the fuel supply 2º with the drain valve at the lowest end to drain off
water and sludge. Sludge may have to manually be removed.
6.6 Some ordinances may require the fuel supply tank to be vented to outside,
and above the roofline. Check State and Local codes. Keep the vent clear.
6.7 Install the fuel tank fill pipe at the end of the tank and above the drain.
6.8 Label the fuel tank for the recommended fuels. See Section 1.3.
6.9 Strain all fuel with a 50 X 50 mesh strainer before putting fuel into the tank.
6.10 When filling the fuel tank with a motorized pump, never leave unattended to
prevent over filling and/or spillage.
6.11 Keep vent cap on the fuel tank when not filling.
6.12 Refer to Section 3.10 for typical fuel tank installation.
