Now I'm having second thoughts for a couple of reasons. 1) They're aluminum and should they melt, there is a great hole to blast a fire up the tunnel and over the fuel. 2) The proseal has a flashpoint of ~200 degrees. I plan on popping these boxes off and replacing with stainless boxes. Q) What material did you use to seal them? I could use Red RTV, but I'm thinking firewall sealer (brand?) is a better option. I'm also thinking of installing a thermal barrier between the boxes and the firewall. Maybe just a bed of firewall sealer, or a box-sized square of thermal insulation. Q) Anyone else do that? Thanks, Phil ________________________________ Message 2 _____________________________________ Time: 08:22:06 AM PST US From: dogsbark@comcast.net Subject: Re: RV10-List: Heater Boxes / Firewall Sealer Phil, The stainless boxes I installed came with a small tube of sealer that was r ated to 1,600 degrees.=C2- I think some RTV is rated to 600 degrees.=C2 - Can't remember what firewall proseal is rated, but all of these are bet ter than regular proseal.

I mentioned for the exact reason you covered that having SS is a good investment. To save you the time- http://www.planeinnovations.com/new%20heater.htm. The heater bypass comes with a seal so you don't need to worry about RTV. I have a pair and it's a great product!

There have been several Cirrus aircraft that was legal for inadvertent icing encounter and crashed from it. Now the new Cirrus are certified for known icing. I fly a Citation Jet for a company and maybe I don't know enough but you never can tell how much ice is going to accumulate on the aircraft. I personally believe it is a very hard question to answer and to try not to get in icing. If you think the plane will do okay in it, it may persuade you to stay in it. Having said all of that I have been in icing in a plane not made for it. I got out of it as soon as I could. -------- Cust. #40936 RV-10 SB Fuselage N801VR reserved Read this topic online here: http://forums.matronics.com/viewtopic.php?p=264537#264537 ________________________________ Message 6 _____________________________________ Time: 09:12:24 AM PST US Subject: RV10-List: Re: Heater Boxes / Firewall Sealer From: "nukeflyboy" I used a thick (1/8 in) silicone gasket under the heater box. This idea came from Tim (I think) as an unverified way to minimize heat transfer into the tunnel. Sounded like a good idea. Since the sealant is not part of the fire barrier per se, I don't think it matters a lot. High temp RTV should work fine. -------- Dave Moore RV-6 flying RV-10 QB - cabin top/fiberglass hell Read this topic online here: http://forums.matronics.com/viewtopic.php?p=264542#264542 ________________________________ Message 7 _____________________________________ Time: 09:43:01 AM PST US From: "Pascal" Subject: Re: RV10-List: Heater Boxes / Firewall Sealer Mine came with the attachments, I think Paul updated them.

One sets some ground rules. If one is going to fly during the winter in the Midwest the aircraft is going to accept minimal icing or accept some very hazardous VFR underneath. My rules are no continuous flight in icing conditions. No flight near freezing rain. I do accept that I may have to endure 3-5 minutes of climb in IMC to get on top. I may have to accept 3-5 minutes of ice on the approach. Of course the approach must be certainty (well above minimums). I also refuse clearances that will take me into icing until I am ready. SGF approach once offered a lower altitude at 30NM out. My then current temperature was a +2C and the SGF surface temperature was -8C. I refused the descent until vectored and cleared for the ILS approach about 7NM out). At 120KIAS to the marker and then 90KIAS, my exposure to ice would be about 4 minutes. Conditions on the surface were 500 and 2. Yes I picked up some ice during the approach but the runway was long the approach speed was +20KIAS above normal landing speed. I now live in the mountainous west where MEAs are very high and would guarantee icing in IMC except for a few summer months. The rules out here are VFR underneath unless the freezing levels are above freezing at the planned altitude. -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of Strasnuts Sent: Wednesday, September 23, 2009 8:54 AM Subject: RV10-List: Re: Ice You probably won't like my answer since my 10 is not flying, but knowing if a plane (not made for icing) does kind of okay is probably best not knowing.
