just finished (Almost) installing a new big heater in the drivers area (using the (The heater engine water) Built a simple encloser that allows me to use the heater in many ways via 2 flapper doors + the existing control of four 2 inch defroster outlets.
I can>.
Heat the bus the normal way
Discharge 100% of the engine HEAT overboard ( from the heater ) via a 3 inch ABS pipe (Capped when not in use) behind the front bumper on a hot pull/day, without any heat IN the bus.
Suck the air OUT of the bus to overboard.
suck outside air INTO the bus (with water On/off )..
Blow 100 % hot air to the defroster
Also from one of the defroster outlets put hot/cold air to the drivers feet thru a small partision
next to my right leg ...with a cap, on or off as needed..
Three of the defrosters used one to spare !!!!! BTW it blows a lot air....I have a feeling that I missed another action
Ken, didn't you already have your coach heat set up so that you could blow it overboard if you wanted to?
Do you have any pictures?

Hi TOM''''''
Yes Sir, I built the steel parts years ago. I just built a box under the heater to contain the direction of the air flow to the in/out flaps, plus had to hitch it to the water lines and some other minor modifications.
It works as planned and to look at it looks like a plain ole heater.
A couple weeks ago I was doing some stick welding close to heater, the 3 wires to it were laying on the second step as was I, with the ends stripped I plunked the rod holder on the step then my foot knocked it to the wires and mated to the med speed wire I thought it was a turbo prop airplane was after me!!!!I It must have been turning umteen thou RPM
It melted the med resistor and one impellor spun off the shaft, I fixed it and put a rheostat on it, one wire and it runs just fine....
PS......... I have sorted out which is which on the plumbing ...........From previous post
I would like to see pics to. Sounds intresting. Tom Y
I did the same on my MC8, I used the org. big bus heater, in the winter I use it as intended and in the summer cap it off and it is exhausted to the side, adds a lot of extra eng.cooling if needed.
I would like to see some pics also. That sounds like a great idea. Although the bus heater I'm using took the place of the original. Would be nice to be able to cap it off and send it down and out.

Hi Guys........... Pictures won't help much by them selves. I have a fiend coming here Sunday to take pictures and make drawings of the mechanics of operations.
This combination should make it understandable.......................
HANG IN THERE .....................BTW..My Gen exhaust goes up thru the roof. KEN

Stay away from them Fiends, theyer Dangerous.. :-[
Both flaps DOWN = normal bus heating
bottom flap UP-upper flap DOWN = drawing outside air into bus ... The middle plywood panel will be permanent The intake is deep down in the stair well the coldest area !!
bottom flap UP -upper flap UP = drawing in 100% outside air in then discharging overboard To help cool the engine.
Duplicate of pic above
Just to show ABS connection
?
Hi ...A friend posted the pictures for me .... I will be back later to try and explain the operation ... Ken
One more thing it will do..........Bottom flap DOWN upper flap UP it will suck the air from inside the bus and discharge the air overboard via the ABS pipe... No pic of that.
I am thinking of putting a 12 volt 3 inch RV sewer valve on the outer end of ABS pipe being it's not reachable from inside....It goes thru the floor behind the front bumpers.....Ken
Update... The drivers and overboard air now have RV dump valves on them, no caps needed.
Looks like this project generated as much feedback as my other invention,
Which is..........An electronic devise to clean out bird chit from cuckoo clocks ::)
