Lanair XT Tank-Mount Unit Installation Script
In this video, we will guide you through the process of installing a tank-mounted Lanair XT-model waste-oil heater.
If you are interested in, or planning to install a Lanair waste-oil heater, this video should help.
Safety Precautions & Prep
It’s important to follow safety guidelineswhen working on mechanical, plumbing, and electrical equipment. Only allow qualified technicians to work on your system and ensure that the appropriate personal protective equipment and safe practices are used throughout the work.
Unit Inspection
Before accepting delivery of your unit, inspect the shipment to ensure that everything is present and undamaged.
If you encounter signs of missing or damaged parts, delay acceptance of the shipment and contact Lanair customer service immediately.
After receiving shipment, start with the heater-cabinet box.
Remove the packing straps and lid and locate the accessory box within.
Begin laying out the contents in an organized manner until the product manual can be located.
Pause this video and read the product manual in its entirety before proceeding with the installation.
Once familiar with the safety and installation requirements, continue to unpack parts and accessories, and identify any additional parts you will need to ensure that you have the necessary materials to complete the installation.
Unit Installation Prep
Identify an appropriate location to install the furnace, ensuring that safe clearances can be maintained, the unit can be easily serviced, and there is adequate vertical allowance to properly install the chimney flue.
Step One
Position the tank in the intended location and secure it to the floor.
Step Two
Using thread sealant, assemble the ball valve, plug, and nipple, then install the drain assembly into a lower side port of the tank.
Step Three
Use additional plugs to plug any other side ports. Continue to use thread sealant on all hard-pipe-fitting connections.
Step Four
Next, loosely mount the pump assembly to the bracket provided on the tank, allowing it the freedom to slide for later adjustment.
Step Five
Using a vise, preassemble the lower fuel-pickup assembly, comprised of the pickup-tube assembly, a check valve, an adapting elbow, and the pickup strainer assembly. Be sure to install the check valve in the proper orientation, with the arrow pointing in the direction of fuel flow.
Step Six
Install the lower fuel-pickup assembly on the tank, using the bung opposite the pump bracket.
Step Seven
Begin building the upper fuel-pickup by attaching a tee fitting to the top of the pickup tube.
Step Eight
Attach the longer, vertical nipple and cap it off.
Step Nine
Using a vise, preassemble the primary strainer assembly, consisting of the primary strainer, an intake adapter bushing, the shorter horizontal nipple, an output adapter bushing, a brass flare-fitting adapter, and a vacuum gauge.
Step Ten
Affix the primary strainer assembly to the pickup tee.
Step Eleven
Loosely connect the pre assembled copper pipe with flare fittings to the primary strainer assembly.
Step Twelve
Remove the inlet plug from the fuel pump and install the brass flare-fitting adapter. Some fuel may be present from the pump’s factory testing.
Step Thirteen
Connect the copper flare-fitted pipe from the primary strainer to the fuel pump and tighten the fittings.
Step Fourteen
You can now tighten the pump assembly to the bracket to lock it into position.
Step Fifteen
Locate the fuel-return pipe packed in one of the tank-stand legs.
Step Sixteen
Using a vise, preassembly the oil-pressure bypass regulator, which is comprised of the regulator assembly, a threaded nipple, the return-pipe adapter, an intake compression-fitting elbow, and an output compression-fitting elbow.
Step Seventeen
Orient the elbows so that the pump-side elbow will be pointing downward and the burner-side elbow will be pointing upward when the assembly is in its installed position.
Step Eighteen
Attach the oil-pressure bypass regulator assembly to the return pipe and install the assembly to the small bung on the top of the tank.
Step Nineteen
Fit the tank-stand legs into the receiving posts of the tank.
Step Twenty
Orient the mounting platform on a forklift so that it will align with the tank-stand legs and slide the heater cabinet onto the platform, making sure that the heater is also oriented correctly.
Step Twenty One
Raise the forklift enough to center the heater cabinet on the platform and attach them with sheet metal screws.
Step Twenty Two
Carefully align the tank-stand legs and slowly lower the heater cabinet and platform into the legs.
Step Twenty Three
Install a threaded nipple, adapter, and compression-fitting elbow to the outlet port of the fuel pump.
Step Twenty Four
Measure the distance of a route for a copper pipe to connect the fuel pump outlet to the input of the oil pressure bypass regulator and use a cutting wheel to cut a piece of piping to the appropriate length.
Step Twenty Five
Using a pipe-forming tool, bend the soft copper line along the route of the pipeline, being careful not to kink or crimp the line.
Step Twenty Six
Slide the compression nuts and ferrules onto the ends of the bent section of pipe and install it on the unit.
Step Twenty Seven
Repeat this process for a copper pipe to connect the oil-pressure bypass regulator output to the input of the burner.
Step Twenty Eight
Connect a compression-fitting elbow to the input of the burner and install the pipe.
Step Twenty Nine
Use the bracket on the heater cabinet to mount the secondary air-pressure regulator and provide a compressed air supply from a primary air-pressure regulator capable of sustaining 2 cubic feet per minute at 30 PSI to the unit. Refer back to the product manual for additional air-supply requirements and guidelines. The product manual also contains important requirements and guidelines for the dedicated electrical supply to the unit. If you have questions about your particular installation, contact Lanair technical support for further assistance.
Step Thirty
Use the electrical conduit provided to connect the pump to the junction box on the heater cabinet. This is also the location for an electrician to connect your incoming power-supply conduit.
Step Thirty One
Leave the circuit breaker off and locked out until installation is complete and the heater is ready to begin the startup sequence.
Step Thirty Two
Replace the junction cover and connect the wiring harness to the burner
Step Thirty Three
Secure any excess slack in the conduit to the frame of the unit.
Step Thirty Four
Install the thermostat on the wall and connect a pair of low-voltage wires from the thermostat to the T1 and T2 terminals of the primary control of the burner.
Step Thirty Five
Plan your exhaust chimney flue installation with a roofer and preassemble your tee and damper so that the damper-door hinge is parallel to the floor and accessible for adjustment.
Step Thirty Six
Install the manometer to the heater cabinet, ensuring that it is level.
Step Thirty Seven
Turn the Zero Set knob counterclockwise to its limit then turn it clockwise for 2 full rotations
Step Thirty Eight
Remove the fill cap and slowly add manometer fluid until it just becomes visible in the gauge.
Step Thirty Nine
Connect the tubing to the draft probe and the “low” port of the manometer.
Step Forty
With the probe not inserted into the chimney flue, turn the Zero Set now until the manometer gauge reads ZERO.
Step Forty One
Find or create a small hole for the manometer probe between the heater outlet and before the tee and damper. Insert the probe. Once the electrical supply and chimney flue work has been completed, your unit is ready to proceed to the initial startup sequence.
