Fuel Tank
General Requirements
Model RAB boilers are approved to burn used crankcase oil, transmission fluid,
and No. 2 fuel oil. Maximum fuel input for a Model 140 is 1.0 GPH (3.8
L/H);for a Model 235 is 1.7 GPH (6.4 L/H); for a Model 350 is 2.5 GPH (9.5
L/H); and for a Model 500 is 3.6 GPH (13.7 L/H)
The oil supply tank and fuel lines must be installed in accordance with the
National Board of Fire Underwriters requirements and all local ordinances. A
UL-listed tank such as Reznor
®
Model OT-250 or equivalent must be used.
In the U.S.
, regulations require that storage tanks located inside buildings shall
not exceed 275 gallons (1,041 L) individual capacity or 550 gallons (2,082 L)
aggregate capacity in one building.
In Canada
, regulations require storage tanks located inside buildings shall not
exceed 550 gallons (2,082 L) individual capacity or 1,100 gallons (4,164 L)
aggregate in one building.
Check with the local Fire Marshall to assure compliance with local ordinances
and codes.
Installation of the tank and supply lines is the responsibility of the
installer.
Fuel Tank
CAUTION: It is recommended that used oil be at a
temperature of 50
o
F or higher when it enters the pump. At
a temperature below 50
o
F, oil becomes more viscous and
difficult to pump. The heater may fire at a reduced rate
and become erratic resulting in nuisance shutdowns.
Install either a UL listed Reznor
®
Model OT-250 oil supply tank or a field-
supplied equivalent indoor storage tank.
•
If installing a Model OT-250 tank, follow the installation requirements
and instructions on the tank.
•
If installing a field-supplied tank, follow the manufacturer’s instruc-
tions.
•
The used oil supply tank should be no closer than 5 ft (1.5 M) and no
farther than 50 ft (15 M) from the boiler. If the tank is lower than the
boiler, height from the pump to the boiler should be no more than 15 ft
(4.5 M).
See the illustrations on pages 11 and 12 for examples of tank and line installa-
tion.
WARNINGS: Never pour gasoline or used oil containing
gasoline into the supply tank. Adequate ventilation must
be provided in any enclosures where storage tanks, pumps,
or accessories are installed.
