FIRMAN T07573 Tri-Fuel Generator Review Canada
This generator must operate outdoors only, well away from doors, windows and vents, exactly as the current manual requires. Never use it in a garage, shed or enclosed porch. Never backfeed a home. Household wiring requires approved transfer equipment, correct bonding/neutral treatment and a qualified electrician.
Quick verdict: T07573 is a conventional 120/240V tri-fuel generator to assess for a professionally planned backup setup. Fuel flexibility is its main distinction, but running output changes with fuel. Its weight, sound and connection requirements make it a different purchase from a small portable inverter.
Exact model, specifications and Canadian availability
This review covers FIRMAN T07573. Costco Canada listed the exact model as item 1900555 on September 14, 2026. Amazon.ca search results did not expose a verified exact T07573 offer—the visible generator result did not state the model—so the purchase link below goes to the exact Costco listing rather than to an uncertain or alternate generator. Delivery eligibility varies by postal code and Costco membership may be required.

Three fuels, three different output ratings
Gasoline provides the highest published starting and running wattage. Propane output is lower, and natural-gas output is lower again. Load planning must use the exact continuous rating for the fuel that will actually be connected—not the largest gasoline number printed on the generator. A motor that starts on gasoline may exceed available surge capacity on natural gas.
120/240V is the key home-backup advantage
Unlike the 120V-only Honda and Champion inverter models in this group, T07573 can supply split-phase 120/240V through its appropriate outlet. That allows a professionally designed transfer system to serve selected 240V loads and both legs of a panel. It does not mean every household circuit can run simultaneously; total continuous watts, per-leg current and motor surge still govern.
What it can realistically back up
With an electrician-designed load plan, this class can support refrigeration, furnace or boiler controls, lights, internet, selected receptacles, a compatible well or sump pump and carefully managed cooking loads. Central air, electric water heating, ranges, dryers and resistance heating can consume much or all of the generator’s capacity. Essential circuits should be prioritized before an outage.
Per-leg balance matters
A 120/240V generator has two 120V legs. Total wattage alone does not prevent one leg from being overloaded while the other is lightly used. Transfer-panel design and circuit placement should balance expected 120V loads. This is one reason a qualified electrician is necessary rather than relying on a homemade cord arrangement.
Natural gas: convenience with installation requirements
Natural gas can eliminate gasoline rotation and propane-cylinder changes during a long outage, provided municipal gas remains available. The generator needs adequate gas pressure and flow through correctly sized approved piping and hose. Long runs, undersized lines and other appliances can reduce available supply. A licensed gas professional should verify the installation and local requirements.
Propane in deep cold
Propane must vaporize in the cylinder. Cold temperature, low fuel level and small cylinder size reduce vapour delivery, which can limit high-output operation. Follow FIRMAN’s cylinder and regulator guidance. A large rated wattage does not help if the fuel system cannot supply enough vapour during a Canadian cold snap.
Gasoline strategy
Gasoline offers maximum output and easy refuelling but requires safe legal storage, rotation and carburetor/fuel-system management. Shut down and allow the generator to cool before refuelling. Never store gasoline beside the operating generator or inside living space.
Power quality and electronics
FIRMAN publishes 11–14% total harmonic distortion at full load for T07573. This is a conventional open-frame generator rather than a variable-speed inverter. Before powering sensitive equipment, verify the equipment manufacturer’s tolerance for this output. Surge protection alone does not correct waveform distortion or make the generator inverter-grade.
Noise and placement
Open-frame output comes with substantially more sound than a small enclosed inverter. Walls can reflect noise, but the generator must never be moved into an unsafe enclosure to quiet it. Placement should first satisfy carbon-monoxide, fire, exhaust, weather and cord-routing requirements; neighbour impact is managed within those safety limits.
Weight and mobility
This is a heavy wheeled generator, not a one-hand portable. Plan the path from storage to the approved outdoor operating location, including steps, snow and soft ground. Wheels help on level surfaces but do not make loading into a vehicle a one-person task.
Cold-weather starting
Use the specified oil grade, keep the starting battery maintained, protect controls from precipitation without enclosing the machine and clear snow from cooling and exhaust paths. Test all three fuel modes before winter. An electric-start feature is only dependable when the battery and fuel system are maintained.
Transfer equipment and inlet sizing
The home inlet, cord, breaker and transfer device must be rated for the intended generator connection and installed under applicable code. The neutral/ground arrangement must match the transfer design. A 50-amp receptacle does not mean the generator can continuously provide 50 amps on every conductor; the engine’s fuel-specific wattage remains the limit.
Maintenance and outage readiness
Track oil changes, air-filter and spark-plug service, starting-battery condition, fuel hoses and regulator inspection. Exercise the generator under load and test the home transfer procedure. Keep printed instructions available because an outage may also interrupt internet access.
Choose T07573 when / skip it when
Choose it when selected 120/240V home loads and three-fuel resilience justify the weight and noise. Skip it when the need is quiet camping power, one-person lifting or only a refrigerator and electronics. Honda EU3200i and Champion 201319 are easier 120V tools; neither replaces T07573’s split-phase role.
Owner evidence
The owner evidence recorded on September 14, 2026 includes exact-model retailer reports, some syndicated or incentivized. Overlapping reports should not be counted as independent confirmation, and those historical samples are not a fresh assessment of current production.
What owners report
Tri-fuel flexibility, straightforward setup and successful extended-outage use recur positively. Substantial lifting weight, open-frame noise and natural-gas starting or supply-line sensitivity recur as practical cautions. An electrician and, for natural gas, a qualified gas professional should size the installation.
Independent evidence
No qualifying independent controlled test that clearly isolates the exact FIRMAN T07573 was found during this review.
Why we’re confident
FIRMAN’s exact-model documentation supports identity and rated capacity. The historical retailer and ownership records provide context, not current stock verification or a controlled performance comparison. Commercial collection and syndication limit how much confidence can be placed in the owner sample.

Evidence and limits
The exact T07573 identity, fuel-specific ratings, 120/240V architecture, 439 cc engine, outlet configuration, runtime, 74 dBA quarter-load claim, unit weight and warranty are documented. Actual starting capacity, fuel supply and sound depend on installation, temperature, load and maintenance.
Bottom line
FIRMAN T07573 is worth considering as a serious portable home-backup generator when an electrician-designed 120/240V load plan and a reliable fuel strategy are in place. Its flexibility is real, but safe installation and fuel-specific derating matter more than the largest headline wattage.
