6.1 General Information
This heater installation must follow the American Boat & Yacht Council, Inc. (ABYC) guidelines.
The Fuel system conforms to Inland Waterways specifications.
Several specific regulations may apply including the use of flame resistant fuel pipe such as copper pipe, and
fire resistant fixings.
The fuel must be extracted from the fuel tank of the vessel by means of a separate fuel pick-up (standpipe).
Do not "Tee" into engine fuel delivery or return lines.
Suitable fuel extraction devices or tank pick-up devices are contained in the accessory lists for the heaters, or
are included in the heater kit.
If an additional fuel tank needs to be installed for the fuel supply of the heater, we recommend this be
carried out by a marine installation center familiar with applicable marine industry directives, codes and
standards. Any safety hazards can thus be avoided.
6.2 Fuel Standpipe Installation
The fuel standpipe should be kept 25mm (1 in.) off the bottom of the fuel tank to prevent drawing sediment
and water into the heater's fuel system.
