Hurricane Maintenance
Hello Everyone:
Someone just asked me if there is anything they should do to their Hurricane Heater so I called ITR and here is the answer:
Every 1000 hours you should pull out the combustion chamber. There is a video at the bottom of the page at the following link:

If you pull it out and find only a little white ash everything is fine. If not call ITR.
You should also check the brushes on the March water pump. To do this look at the pump and find the two dime sized round plastic plugs on the side of the pump. You can remove them with a slot screw driver. When you pull them out you will find a spring with a magnet on the end. The magnet is the "brush". When they are new they are 3/4" long. They need to be replaced when they get to 1/8".
The only other routine maintenance is to change the fuel filters.

Hurricane Heater
If you have the optional AC element on your Hurricane Heater, add an on/off switch to the water circulating pump circuit in the master ITR controller. This will keep your boat around 40 degrees through the winter months. To keep it running, you should also change out the March water pump for a brushless water pump.
Replacement Pump part number??
Bill-
Do you have a part number for a replacement brushless motor? I'd also like to add that the same circulation pump switch can be used when underway - so that if your engine supplies heat to the circulating water - the furnace does not need to run but the heated water (from the engine) can be used to heat the boat.
ITR told me that this is a very good idea under heavy weather conditions. They recommend leaving the remote switch off, turning on the circulation pump (via switch to ground on the A terminal if I recall correctly - its shown in the schematic) and plug the exhaust / intake with a special plug they supply ($50 USD) that prevents water from entering the system from heavy seas. Its a good idea to also use it while washing the boat to keep hose spray from going straight into the exhaust / inlet.

Hurricane Circulating Pump
We use a brushless Johnson heavy duty, magnetic drive, sealless circulating pump flanged to a 12/24/32 volt DC motor (model CM30P7-1 P/N 10-24504-03) to circulate water through our Hurricane heater. We paid $184.53 for the pump, but you can find them on the Internet for $175.00 to $200.00. You might note that the CM30 circulates at between 5 to 7 GPM and draws less than 2 amps, for better performance than the brush-driven ITR supplied pump.
