Airstream Water Heater
The restoration project of the 1970 Airstream Overlander Land Yacht Trailer continues. In this episode, the show's host Kevin Tetz, introduces Neil Sultz from Suburban Manufacturing to help him with installing a new furnace for the trailer.
According to Kevin, the current furnace the RV has is around thirty years old. Neil says that the typical life of an RV furnace is only ten to fifteen years old. So you know what that means? It's time to replace the old furnace!
Neil gives Kevin some guidelines when shopping for a furnace system. Neil says that you should consider the length of the coach for which you want to install the furnace into. The 1970 Airstream Overlander Land Yacht Trailer that they are restoring is twenty-seven feet long (27 ft). Neil says that it needs a twenty thousand BTU (20,000 BTU) furnace approximately.
He adds that you should calculate at least one thousand BTU (1,000 BTU) for each foot of the trailer. Neil says that you should also look at the space you have and consider how you can adapt it to the deck work.
Before taking the old furnace out, Neil cautions us to make sure that the LP gas is off. Then he removes the exterior furnace vent. Next, he disconnects the 12-Volt wiring, the thermostat wires and the LP gas line. Neil and Kevin work together to remove the heater assembly from the cabinet and remove the entire furnace cabinet as well.
Then they start moving the new furnace in by starting off with the new duct box and screwing the cabinet into place. Neil makes sure that the gas line is connected and does a leak check. Kevin recommends checking out diynetwork.com for more information on checking on gas leaks.
When the furnace installation was done, Kevin installed a new thermostat into the bedroom wall. He removed the old thermostat first and attached a new unit by attaching it to the wires that were left behind. Then he fastened the new unit to the wall.
The video ends with Kevin telling Neil what a great job he's done with the furnace.
