Force 10 Cozy Cabin Heater in Sea Wolf.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:18:22 2003
  Here's the completed installation. There's no room on the floor for installing a heater on the CD-22 Cruiser. I found some space between the sink and the stove in which to mount the heater . Usually they'e mounted in the rear corner, but my three burner cooking stove would have lost the use of one burner. A gas leak in this location would result in most of the heavier than air proane going down the drain and out the side of the boat, provbiding the sink is empty and the stopper is not in place. Details to follow in subsequent photos.


 

Bracket Assembly.

Here's the aluminum and wood mounting bracket assembly I fabricated.
  


 

Heater preliminarily installed.

   Between the heater and the bracket is a stainless steel lid off of a slurpee machine that conveniently fits the bill for a heat shield and is stamped into a rigid three dimensional form that is a lot stronger than flat sheet metal. The uninstalled propane alarm, carbon monoxide alarm, fire alarm, and electric control panel are visible to the right.


 

Impromptu Pipe Bender

The 1" stainless steel railing that is used as an exhaust stack is pretty tough stuff. There's no railmaker in Redding, so I decided to do it with what I had. Wrap it in tape to avoid marking the tube up.

From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:31:38 2003
The exhaust tube has to bend to go out the roof somewhat perpendicular to the roof plane. By using two teak winch pads that are angled at 15 degrees, the approach to a right angle is approximated. The roof heat shield is fiberboard covered with thick aluminum foil and is from the back of an electronic appliance. Careful with the screws here, the roof is only about 5/16" thick!


 

Exhaust stack exits through roof.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:34:15 2003
  I lined the roof and inside of the winch pads with several thicknesses of aluminum tape to repel heat after sealing the balsa core up with epoxy. The tube is not supposed to touch the finishing ring inside nor the exhaust cap outside to avoid transfering a lot of heat through contact.


 

Exhaust cap installed.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:35:41 2003
The finished exhaust cap sits on a heat resistant (asbestos, but don't tell anyone) gasket. Behind the cap is a roof vent installed to let out cooking odors and heat, etc. Works great with no electric moving parts. I leave it partially open all year to keep the cabin fresh except in driving rain.
  


 

Lower Fan Assembly.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:40:52 2003
Here's a photo showing the lower fan mounted in the pick-up grille. I had to file down the square corners of the plastic fan case to make it fit in the round grille fitting. These motors are very quiet.


 

Fan Intake.

  Here's a view of the fan intake from the other side.


 

Fan and Tube Assembly Under Galley.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:45:47 2003
You can see the reducer bushing (4" to 3") and 3" dryer tube that leads up to the back of the stove. I was glad I could hide this under the sink/galley cabinet for asthetic reasons. There's a 3" pvc pipe that acts as a nipple from the bushings into the flexible tube.


 

Cold air pick-up system.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:37:07 2003
   The green plastic grill (water intake screen a-la-storm drain) is part of a system I devised to pick up the cold air off the floor and pipe it up to the heater in order to avoid stratification or layering of the heat in the cabin. Force 10 wants you to mount the heater closer to the floor than the counter top, but in the CD-22 Cruiser, all the floor space is pretty much dedicated. With the heater at counter top level, a method of mixing up the cabin air is needed. Air is taken in here at the center lowest point in the boat and transfered up to the heater via two small computer power supply fan motors that draw only 0.12 amps each or a total of 2.4 amp-hours for a 10 hour run for both. Hardly taxes a 90 amp-hour battery! The propane alarm can be seen at the left.


 

Cold Air Exit Behind Heater, Second Fan.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:47:15 2003
   The flexible tube connects to a 22 1/2 degree pvc fitting behind the heater. Air is then picked up by a second fan mounted behind the heater and sent over the heater, cooling the roof and exhaust stack while being heated up and mixed with hot air from the heater on the front side. The fan has to be on the back side as the heater depends on it's own convection to pass heat out of it, and a blowing fan on the front would disturb the flame at the burner. Both fans are individually controlled at the 4-gang switch panel. The other two of the four switches control the propane detector and the carbon monoxide detector. There's also a battery powered fire alarm on the ceiling. I placed dthe stove's burner and all of the alarms and the control panel in not only the correct place for their best operation, but also where I can comfortably check their pilot lights out from where I sleep in the berth on the dinnette conversion. (My 150 lb Great Dane, Shadow, sleeps in the v-berth.)   


 

Completed Project.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:48:43 2003
Here's the whole thing again. I thought it would be only smart to add the carbon monoxide amd propane alarms. The CO alarm monitors levels of CO with a computer progrm that models the human body and adds up the effects of a long term low-level as well as short term high-level exposure. It's placed in the rear corner at the top of the port side of the cabin. The propane alarm is sensitive to not only propane, but also gas, alcohol, acetone, and a host of similar bad guys. It's next to the floor in front of the heater behind the helm where the heavier than air propane would collect if it didn't all go down the sink and out of the boat. (Shown in previous photo). The fire alarm is on the roof interior and is the same type you have at home. The screen on top of the heater is a stainless fire grille from off the front of a commercial water heater. It's wired/woven to the top of the stove with 1/16" stainless cable. I put it there to trap my coffee cup or the small stainless pot in the corner at the right.   


 

Time to Light My Fire.  
From: Sea Wolf (Sea Wolf)  Sun Nov 2 14:50:25 2003
Time to enjoy the completed installation and "Light My Fire" (with apologies to the late Jim Morrison and The Doors). Hope this has been helpful. If you have questions, just ask. I've spent a lot of time thinking about where and how to install this heater. As usual, the best solution is simple, elegant, and looks easy once it's done. I installed this heater in heat up to well over 100 degrees in the Summer in Redding. Our hottest day here this summer was 116!!! Bring on some cold air! Joe


 

Propane Tank Location on Sea Wolf  
From: Sea Wolf (Sea Wolf)  Tue Aug 26 13:33:27 2008
Old '87 Evinrude 90 hp V-4 replaced in 2005 with new Yamaha 90 EFI. Tank of 20 lbs of propane lasts at least a year here in Redding, Ca.!

I would love to see pic's of this when it is completed.....


 

Tim, I don't know who you stole this idea from but I stole it from you.

By far, the biggest hole we've cut in our boats, eh?

two coats of DeltaT insulation over two coats of DeltaTdb. they say this would be equilivent in R value to about 2" of foam

this a picture of the sprayed in insulation in the ice box hole. The insulation was spayed in two coats for a total of about .040 thick

I think I need to add a chunk of hull linner to that rode locker. ye old sandblast gun with a jug stuck on the pick up tube, works like a champ

OK Where to I get me one of these???

From: Sunbeam (Sunbeam)  Sat Sep 13 12:51:16 2014
I'm not the boat owner, but I asked the same question in a thread where the owner showed the mod. As I recall he bought it at a garage sale (or the like) and did not know.

From: Sunbeam (Sunbeam)  Sat Sep 13 12:52:15 2014
(went over character limit so part 2): Looks a bit like second row van seating. I have looked at some takeout seating on eBay, etc. and seen similar seats but not the same. I'd like to get one too.

From: Sunbeam (Sunbeam)  Sat Sep 13 12:52:42 2014
Perhaps from a Honda or similar
