Why Choose a Furnace for Your Trailer?

In the long run, a good installation of propane or gas furnace constitutes the most efficient and most effective heating of a trailer. There is a reason for that:

  • Even Heat Distribution: Warm air again exits the duct from various outlets and waves to all portions of your trailer.
  • Energy Efficient: Modern trailer furnaces are little in size and consume very little fuel.
  • Safe Operation: They are designed to safely operate in confined spaces with adequate ventilation.
  • Thermostat Control: Max comfortable is attained by setting the desired temperature.

Tools & Materials Required

Before entering the installation phase, make sure you or the installer have the proper tools and materials: 

Tools:

  • Cordless drill
  • Wrenches and ratchet set
  • Screwdrivers (flathead & Phillips)
  • Tin snips
  • Tape measure
  • Gas line tools (flaring tool, pipe thread compound)
  • Multimeter (for electrical connections)

Materials:

  • Trailer-rated furnace (LP or natural gas)
  • Thermostat
  • Exhaust venting kit
  • Flexible ducting
  • Return air grille
  • Gas line fittings
  • Electrical wiring and fuse
  • Sealant and foil tape
  • Mounting brackets

Note: If you don’t know the working of gas lines or systems or with electricity, call an honorable licensed HVAC technician.

Step-by-Step Guide to Installing a Furnace in Your Trailer

Step 1: Choose the Right Furnace

Trailer furnaces are not the same as residential models. They are compact, vented, and rated for mobile or modular use. Common options include:

  • Direct-vent propane furnaces
  • Wall-mounted forced-air units
  • Underfloor ducted systems

The square footage of the trailer and climatic conditions must be considered.A trailer of normal size in Edmonton would require one that can put out 30,000 to 40,000 BTUs.

Step 2: Identify the Installation Location

You’ll need to choose a location that provides:

  • Adequate clearance from walls and combustibles
  • Access to outside walls for exhaust venting
  • Proximity to the gas line and electrical supply
  • Easy airflow for intake and distribution ducts

Many furnaces are installed in utility closets, under benches, or in lower wall cavities.

Step 3: Prepare Venting Access

In order for combustion gases to be expelled outside, the furnace has to be vented to the exterior. An opening has to be cut into the side of your trailer to house the intake/exhaust system. 

Tips:

  • For small, round holes, use a hole saw, and for bigger cuts, use an electric jigsaw.
  • Always adhere to furnace manufacturer’s venting specifications.
  • Each edge should be sealed with a silicon-based high-temperature caulk or with foil tape: never allow an opening or draft to exist.

Step 4: Install the Furnace

Secure the furnace by mounting it with brackets or base plate provided so that it rests firmly on its base and does not move while the trailer is being driven.

Fitting of intake and exhaust pipe through the trailer wall is done next, with attachment by clamps or screws, then sealing is done as per code.

Step 5: Connect the Gas Supply Line

Warning: Only a licensed gas fitter should be able to complete this step. An accidental leak of propane can be fatal if not taken care of with due consideration.

  • Shut off the main propane supply.
  • Use approved gas-rated fittings and sealant.
  • Connect the furnace to the supply line and check for leaks using a bubble test or electronic gas detector.

Zee Jay Mechanical’s certified technicians are fully qualified for gas line installations and testing.

Step 6: Install Electrical Wiring

Most trailer furnaces require 12V DC power to operate the blower and control board. Some also include 120V components.

  • Run wiring from the fuse panel or breaker box.
  • Connect to the thermostat and power terminals on the furnace.
  • Install an inline fuse to protect the circuit.

If batteries go in the system, it might be just a good tip to check their polarity and voltage with a multimeter before energizing the system.

Step 7: Attach the Thermostat

Mount the thermostat on an interior wall. Avoiding heat from direct sunlight or any other heat source is what has to be observed. Connect it with the furnace terminals using low-voltage thermostat wiring (R, W, and C are the most commonly used).

 Programmable thermostats definitely render you ample control and energy savings.

Step 8: Connect Ductwork

If your furnace supports ducted heat distribution:

  • Connect flexible or rigid ducting to the supply plenum.
  • Route ducts to floor or wall registers throughout the trailer.
  • This return is needed right nearby the lower side of the furnace to ensure the circulatory air.

Use foil tape, not standard duct tape, to seal connections and prevent air leaks.

Step 9: Test the System

Before using the furnace regularly:

1.Turn on the gas and inspect for leaks.

2.Restore power and set the thermostat to “Heat”.

3.Ensure that the blower fan starts, the burner ignites, and warm air flows to each register.

4.If the user wishes, one can act to ensure proper air flow is moving outside of it.

Step 10: Schedule a Final Inspection

Even if all signs show perfect working conditions, a professional checkup is advised. Certified HVAC installers will:

  • Check for carbon monoxide risks
  • Confirm venting integrity
  • Test combustion efficiency
  • Verify electrical and gas safety compliance

Why You Should Hire a Professional for Trailer Furnace Installation

While it’s possible to install a furnace yourself, professional installation is safer, faster, and often required by law or insurance. Here’s why:

Warranty Protection

Manufacturers often require professional installation to honor product warranties. Zee Jay Mechanical ensures your equipment is registered and protected.

Safety Assurance

Gas or electrical systems pose a hazard. Right tools, equipment for testing, and methods must be applied by licensed technicians to avert the menace of fire or carbon monoxide.

Time and Cost Efficiency
