HEAT 

 

The Hurricane diesel hydronic heater is located in the engine room on the port side.  
It provides heat by heating water which then runs to various heat exchangers.  Turn 
on the toggle switch in the main salon

 

and set the thermostat at the desired 

temperature.  If the heater does not start or shuts off, turn the switch off, let it sit 
for 10 minutes and restart.  Once the heaters is running, it will take some time for 
the water to heat.  Once up to temperature the fans in the main salon and 
staterooms will turn on and off on automatically.  The potable hot water will also be 
available.  

The potable water heated with this system can be very hot.

  Be cautious 

when running the hot water taps or shower. 
 
Check the exhaust port on the stern to make certain that no obstruction such as a 
fender or line exists.  Let the furnace run at least 15 minutes before turning it off.  
Each stateroom and the main salon has a thermostat and there is a switch in the 
pilot house.  The power to the pilot house heat must be turned on at the DC panel 
and then at the switch above your right knee as you sit at the helm. 
 
Engine heat can be used to heat the system.  A switch near the main heat control 
panel turns this feature on.
