Step 1: First Up You Need a Donor Propane Furnace
Step 2: First Step Was the Hardest. Ripping It Out of the Camper Was a Task of Its Own!
Step 3: I Had a Problem With the Igniter and Thermocouple.
Step 4: Cutting the Top and Bottom
I'd like to add that the heaters outer shell gets hot but you can still touch it but with that being said I still wanted to follow the old saying. "better safe than sorry"
Step 5: Cutting and Installing
the inverter is (120v ac to 12v dc) it came with 2 separate wall outlets one piggybacked off of the other. I figured I didn't need both of them so I only used the one that was GFCI since it will be outside with a slight chance of it getting wet I wanted no part in the possibility of getting shocked
Step 6: Wiring
Step 7: Installing the Heat Shroud
also fresh air is forced between the heater and shroud through the fan in the heater so the heat shield has constant fresh air keeping it cool
Step 8: Little Things Here and There
2nd picture. I had plenty of space left inside the box to fit the extra long 20 ft cord the inverter came with so I cut a slot to be able to stuff it inside
the thermostat is removable and is attached to a 10ft cord stuffed inside the empty space in the box so you can pull it out and put it in the tent to regulate the temperature
also I installed the entire exhaust system that the camper came with because it was double walled and the best part was it was already made so I didn't have to fabricate anything! that was a plus!!!! also I figured it was safe for the camper so why wouldn't it work in a box!
Step 9: I Know I Skipped a Lot But If You Can't Cut, Measure, Plan and Execute Bring It Over I'll Do It for You.
I'm thinking of making a cover to replace the brown metal grate so I can connect multiple dryer hoses that way I can heat more than one tent
and I saved the best for last because I'm sure I would get some messages about the hose clamp attaching the propane to the heater and how its not safe. I have to flare the copper pipe and attach a coupler and take the hose to the local pipe and hydraulic shop to have an end crimped on...so before I get hit with safety questions its going to be taken care of I promise!
I did this to test it and I figured since there is only 1 psi flowing through the line a hose clamp will do
