Hot Water Heater Installation Recommendation
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.
CAUTION
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 sys-
tem, an air pocket may form in the closed cooling system. This can cause the engine
to overheat.
