Laser 531 / Laser 532 FUEL SYSTEM OPTIONS
• Large Capacity External Tank
Tank must be purchased separately and installed by a qualified fuel supply technician.
EXTERNAL TANK INSTALLATION
NOTE: External tank installation must comply with National Fire Protection Association Code NFPA 31, CSA
Standard B139, the Installation Code for Oil Burning Equipment, or locally applicable codes. Check with
local building officials.
The following instructions should be followed for installation of a large capacity, gravity-fed external fuel tank.
• Installation height of tank's fuel outlet should be at least 16 in. above floor surface upon which heater
rests.
• To avoid excess fuel pressure to heater, top of fuel tank should be no more than 8-1/2 ft. above floor
surface upon which heater rests.
• Fuel tank should be located at least 6 ft. away from all heat sources.
• 3/8” OD copper tubing should be used for fuel line.
• To prevent air locks in fuel line, fuel line should be smooth with no U-shaped or sharp bends.
• Install a UL listed fuel filter at the fuel tank outlet
(it is highly recommended to use an in-line small
mesh size filter with water block, e.g. 10 micro filter). Shut-off valves should also be installed on the
fuel line and connected the tank as illustrated on page 38.
NOTE: An additional shut-off valve installed next to the heater will minimize fuel to be drained should heater have to
be disconnected. If the valve is on interior side, a fusible link type is recommended.
1. Be sure all external tanks have an operating vent.
2. Be sure to observe the maximum and minimum tank heights as specified.
NOTE:
If the maximum height from the top of the fuel tank to the bottom of the heater exceeds 8-1/2 ft., a fuel
pressure reducing valve, preset at 2.5 psi, is required.
Pressure Reducing Valve Part#10005099 has 3/8 in. (N.P.T.) inlet and outlet female openings to accept the
fuel line fittings.
WARNING: Use only ASTM D3699 1-K kerosene, ASTM D396 Low Sulfur No.1 Fuel Oil, ASTM D975 Ultra Low Sulfur Diesel
(ULSD), or Ultra Low Sulfur Heating Oil (ULSHO). NEVER USE GASOLINE. Use of gasoline can lead to uncon-
trollable flames resulting in destructive fire.
