Print Page1 Locating the Tank
The water heater can be mounted anywhere on the vessel as long as the connections to the en-
gine heat exchanger are below the engine header tank (Fig. 1). It is best to keep the length of
the heat exchanger hoses short to keep flow resistance and heat loss to a minimum. In many
installations the tank heat exchanger is simply connected in series with the engine coolant cir-
cuit. In some installations it is connected in parallel with a flow restrictor/diverter. The
choice depends on the specific recommendations of the engine manufacturer and or installer.
Please consult the manufacturer or dealer of your engine for any recommendations they may
have for connecting to the engine cooling system.

2 Mounting
The Isotemp water heater is designed to give
excellent performance when mounted horizon-
tally. The drain must always be at the lowest
point. The mounting brackets can be adjusted
to the side for mounting the tank on a bulk-
head.
Always mount the tank to a suitable
shelf or bulkhead and keep in mind the extra
weight of the tank when it is full of water.
It is possible to remove the insulation from the
tank so that the tank can be passed through a
small opening. In order to do this the fittings
and the electrical connection cover must be
removed. The mounting brackets also need to
be taken off and the two halves of the molded
polyurethane insulation can then be removed.
This will reduce the diameter to 10.5 inches.
