Hot Water Heater Installation Information

IMPORTANT: When connecting a cabin heater or hot water heater, certain require-
ments must be met, including, but not limited to the following:
•
Supply hose (from engine to heater) and return hose (from heater to engine)
MUST NOT EXCEED 5/8 in. (16 mm) I.D. (inside diameter).
•
Make heater connections ONLY at locations indicated in the following informa-
tion.
•
Refer to manufacturers' instructions for complete installation information and
procedures.
IMPORTANT: Do not reposition engine temperature switch; it must remain where in-
stalled by factory.
On closed cooling models, heater must be mounted lower than the fill cap on the
heat exchanger. If the heater is higher than the fill cap on the heat exchanger and
some coolant is lost from system, an air pocket may form in the closed cooling sys-
tem. This can cause the engine to overheat.
