XT150 Value Package 1: the smallest XT cabinet, on exactly the same install as the big one

Here is the useful thing about choosing an XT150, and it is visible if you read this page's specification table against the XT200's. The two units share a cabinet of 24" x 40.25" x 48", the same 413 lbs hanging weight, the same 120 V / 20 amps supply, the same 2 CFM of air at 12-15 PSI and the same 6" Class A flue. What changes between them is heat output and fuel burned, and nothing else.

So the decision is not an engineering one. It is a square-footage one. This unit is rated at 150,000 BTUH across a heating area of 3,500 sq. ft. at 1.07 GPH, and if that covers your building you save fuel every hour it runs by not buying the larger cabinet. The package adds a Class A chimney kit worked out for a 16' eave, so the flue hardware arrives with the appliance.

Getting the size right, in both directions

Oversizing a shop heater is the more common mistake and the more expensive one: a burner that satisfies the thermostat quickly spends its life cycling on and off, which is harder on the appliance and burns fuel to no purpose. Undersizing shows up differently — the unit simply runs continuously in January and the far end of the building never gets warm.

Neither is a specification you can settle from a catalogue. Ceiling height, insulation, how many hours a day the bay doors stand open and your local design temperature all move the answer, and none of them are on this page. Use the 3,500 sq. ft. figure as the starting point it is, and talk to us with your actual building before you commit.

Will It Fit?

Every one of those is the buyer's to confirm against the real building before the freight is booked. A heater that will not fit the room, or a roof structure that will not take the load, is not a warranty matter and it is not a return we can make painless.

The chimney kit in this package

Eleven parts, and they divide into two jobs. Sealing and supporting the roof penetration: roof flashing for pitches from 0/12 to 6/12, a storm collar above it, a finishing collar below, and a roof support bracket to hold the stack steady. Building the run itself: a chimney cap, insulated Class A chimney pipe in 36" and 24" sections, four 24" lengths of black pipe for the interior, a black tee pipe with cap that gives you cleaning access, a 14" slip connector for taking up the last awkward gap, and a 90° elbow for turning the flue out of the cabinet.

Two things to check before ordering: your roof pitch against that 0/12-6/12 flashing, and your eave height against the 16' the kit is cut for. A steeper roof needs a different flashing; a taller building needs more insulated pipe. Both are easy in advance and awkward on install day.

What you are actually buying into

A waste oil heater turns a disposal cost into a heating supply, and it does that by asking for a bit more attention than a gas unit. The fuel is not refined, so quality control is yours: keep the used oil clean, keep water and solvent out of it, and expect to service the combustion side on a schedule rather than when it complains. The manual and brochure are in the downloads section of this page and are worth reading before you buy, not after.

The hardware side supports that. The combustion chamber is 12 gauge CRS — heavy cold-rolled steel where the flame lives. The cabinet is fine-grained galvanized steel, specified against rust in the damp, salty air a working shop generates in winter. The fan sits inside the cabinet rather than on it, which keeps the running noise down in a bay where people are talking. And the discharge louvers adjust and lock, so the heat goes where the work is instead of straight up to the roof deck.

The fuel list is specific: used crankcase oil up to 50 wt, used synthetic oil, used automatic transmission fluid, and #1 and #2 fuel oil, which means it will happily run on bought heating oil when the used-oil tank is empty. Anything not on that list — gasoline, solvent, antifreeze, brake fluid — stays out.

Perfect For

• One- and two-bay independent shops whose building is genuinely in the 3,500 sq. ft. bracket.
• Service departments wanting to stop paying for used-oil collection twice over.
• Small fleet garages with predictable oil-change volume.
• Farm and equipment workshops generating engine, hydraulic and transmission fluid.
• Large home workshops with the roof structure to suspend it and a legal flue route.

Specifications

Certification, stated plainly

The current copy on this product says Lanair's units are UL listed, so we repeat it as the manufacturer's claim rather than as our own. What that claim covers is the appliance. It does not cover your installation, and it is not the same as a local permit or an insurer's agreement to a used-oil burner inside your building — those are decided where you are, sometimes with conditions attached to the tank or the flue. If either party is going to want the listing document on file, ask us for it before you order.

Shipping and Delivery

Freight to the lower 48 states, free of charge. Two things to sort out before you buy. How the crate comes off the truck — forklift, dock, or collecting it yourself from the carrier's terminal. And whether the delivery address is residential, because residential delivery is a separate service that carries a fee. At handover, check the crate over before you sign for it: damage written on the bill of lading at delivery is a claim, damage found after a clean signature usually is not. Photograph anything suspect and keep the packaging until the unit is running.

Warranty

Covered by the manufacturer. The specific terms are not recorded in the data behind this listing, so rather than approximate them we will point you at the source — start at our warranty claims page, and the warranty document is also linked in the downloads section above. Whatever the fault, leave the unit assembled until the claim is open. Taking a burner or a chamber apart first is the single most reliable way to lose a warranty argument.
