Lanair MX300 - Manual (Page 19)

Section 5 - Fuel Supply Tank Installation
16
General Requirements
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.
2. Regulations require oil storage tanks located inside not too exceed 275 gallons individu-
ally, and are not to exceed a total capacity of 550 gallons in one building. Check State
and Local codes.
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.
4. The fuel supply tank must be mounted below the burner and the by-pass regulator (or
supply pump assembly when using the optional metering pump). Mounting the fuel
supply tank above the burner will create head pressure and over-fire the burner voiding
the warranty.
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. 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.
7. Install the fuel tank fill pipe at the end of the tank and above the drain.
8. Label the fuel tank for the recommended fuels.
9. Strain all fuel with a 50 X 50 mesh strainer before putting fuel into the tank.
10. When filling the fuel tank with a motorized pump, never leave unattended to prevent
over filling and/or spillage.
11. Keep cap on the fuel tank when not filling.
If using a Lanair supply tank follow instructions included with the tank.

For optimum performance, the waste oil pump manufacturer recom-
mends that multi-weight oils such as 5W-30W be maintained at 32˚ F
minimum and straight weight oils such as 40W and 50W be maintained
at 50˚ F minimum.
