Hot Water Heater Installation
IMPORTANT: When connecting a cabin heater or hot water heater:
• Supply hose (from engine to heater) and return hose (from heater to engine)
MUST NOT EXCEED 5/8 in. (16 mm) I.D.
• Make heater connections ONLY at locations shown.
• Refer to manufacturers’ instructions for complete installation information and
procedures.
• Do not reposition engine temperature switch.
CAUTION
Avoid a performance loss and/or possible engine damage. Engine coolant must
flow continuously from the engine intake manifold to the engine water circulating
pump. NEVER close-off or block the coolant flow to or from a heater. All heater
installations must be plumbed in series with the supply and return connections.
CAUTION
Avoid engine overheating which could result in engine damage. On models
equipped with Closed Cooling, an air pocket may form in the closed cooling system
if some coolant is lost from the system and the cabin heater or hot water is mounted
higher than the fill cap on the heat exchanger. Heater must be mounted lower
than
the fill cap of the heat exchanger on models so equipped.

NOTE: Some models may be equipped with additional fittings.
