Toyotomi laser 30 type b Operating Guide

¡ Large Capacity External Tank

Tank must be purchased separately and installed by a qualified fuel supply technician.

NOTE:

External tank installation must comply with National Fire Protection Association Code NFPA 31 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.
¡Use of fuel filter in fuel line adjacent to tank is recommended, shut-off valves should also be

installed on the fuel line and connected to the tank as shown below.

NOTE:

An additional shut-off valve installed next to the exterior wall will minimize fuel to be drained
should heater have to be disconnected. If the valve is on interior side, a fusible link type is recom-
mended.

1. Be sure all external tanks have an operating vent.
2. The use of a water trap filter is recommended. A model with a drain plug or petcock is preferred.
3. Be sure to observe the maximum and minimum tank heights as specified.

NOTE:

If the maximum height is exceeded, a fuel pressure limiting valve which must be set at 2.5 psi with
3/8-in. fitting is required.
Check with your local Toyostove dealer for availability.

NOTE:

Fusible Link Valve (#10005597)
¡It is most important that the valve, depending on its use, be fully opened or fully closed.
¡The top nut on the valve  (below the turn handle) is sealed and should never be tightened or

removed.

¡When installing fuel lines to the valve, be sure to check for fuel leakage.
¡A LEAKING VALVE SHOULD ALWAYS BE REPLACED.
