Can I Run My FIRMAN Generator in the Rain?
Yes, with the right outdoor generator protection. FIRMAN generator owners should never rely on tarps, improvised shelters, plastic boxes, or enclosed structures that can restrict airflow, trap heat, interfere with exhaust, or create carbon monoxide hazards. GenTent® generator running covers are engineered to help compatible FIRMAN portable generators operate outdoors in rain, snow, sleet, wind, storms, blizzards, ice storms, hurricane-season outages, and other severe weather conditions while protecting the electrical panel and maintaining the open-air environment portable generators require.

Match Your FIRMAN Generator to the Right GenTent Category
FIRMAN portable generators include open frame, inverter, dual fuel, tri fuel, home backup, jobsite, recreational, and emergency power models. That means there is not one single FIRMAN generator cover that fits every FIRMAN generator. The correct GenTent depends on the generator body style, frame perimeter, accessible mounting points, exhaust location, control panel location, and whether the generator is an open frame model or a fully enclosed inverter.
For many FIRMAN open frame generators, including many dual fuel and tri fuel models, the correct fit path is typically a GenTent Universal or XL Universal system, depending on frame size, frame access, and generator perimeter. For fully enclosed FIRMAN inverter generators, the correct fit path is typically a GenTent inverter-style running cover using a strap-mounted frame system. Larger fully enclosed generator cases may require the XL Inverter fit range.
GenTent® Generator Running Covers for FIRMAN® Generators
GenTent products for FIRMAN generators are GenTent branded accessories. They are not FIRMAN OEM, FIRMAN co-branded, or FIRMAN endorsed products. GenTent’s design approach supports the same safety priorities FIRMAN emphasizes for portable generator owners: outdoor operation, carbon monoxide awareness, proper placement, dry electrical operation, and safe use during backup power events.
FIRMAN CO Alert™ equipped generators are designed to monitor carbon monoxide conditions near the generator and shut down when harmful carbon monoxide levels are detected. GenTent running covers are designed to work with modern CO shutoff sensor equipped generators by maintaining airflow, exhaust clearance, and outdoor operating conditions when installed correctly. Always operate portable generators outdoors, away from doors, windows, vents, garages, crawl spaces, and occupied areas.
FIRMAN Power Equipment is listed as a member of the Portable Generator Manufacturers' Association (PGMA). PGMA advances portable generator safety and performance standards and educates consumers through the Take it Outside™ campaign.

Protect Your FIRMAN Generator or Inverter with Engineered Weather Protection
If you're searching for the best rain, snow, storm, blizzard, ice storm, or hurricane-season cover for your FIRMAN generator or inverter, GenTent® is built for the way portable generators need to operate outdoors. GenTent helps protect compatible FIRMAN generators from severe weather while supporting airflow, exhaust clearance, electrical panel protection, service access, and CO shutoff sensor compatibility when properly installed.
FIRMAN emphasizes outdoor generator operation, carbon monoxide awareness, proper placement, dry operation, and ventilation. GenTent is designed around those same safety priorities, giving FIRMAN generator owners a purpose-built alternative to tarps, plastic bins, sheds, or improvised covers that can restrict airflow, trap heat, or interfere with exhaust.
FIRMAN Generator Weather Protection FAQ
FIRMAN generators should be operated outdoors with proper safety precautions and kept dry. GenTent generator running covers help compatible FIRMAN generators operate outdoors in rain, snow, sleet, wind, and severe weather while protecting the electrical panel and maintaining airflow, exhaust clearance, and access to key operating areas when properly installed.
Never operate a generator inside a garage, home, crawl space, basement, shed, vehicle, tent, or partially enclosed area.
GenTent recommends operating portable generators outdoors and at least 20 feet from doors, windows, vents, garages, crawl spaces, and occupied areas, with exhaust directed away from people and structures.
Always follow your FIRMAN owner’s manual and current local safety guidance for generator placement, extension cords, grounding, fuel selection, and home backup connection.
GenTent products are designed for use with modern CO shutoff sensor equipped generators when properly installed. The GenTent design maintains the open-air operating environment portable generators require, including airflow, cooling, exhaust clearance, and outdoor operating conditions.
FIRMAN CO Alert™ equipped generators monitor carbon monoxide conditions near the generator and are designed to shut down when harmful carbon monoxide levels are detected. GenTent does not replace CO safety practices. Always operate your generator outdoors, away from openings, and follow FIRMAN’s safety instructions.
FIRMAN generator fit depends on generator style, frame access, case or frame perimeter, exhaust location, control panel layout, fuel selector access, and whether the generator is an open frame model, open frame inverter, or fully enclosed inverter.
Many FIRMAN open frame dual fuel and tri fuel generators follow the GenTent Universal or XL Universal fit path, depending on the generator’s frame size and mounting access. Many FIRMAN fully enclosed inverter generators follow the GenTent Inverter or XL Inverter fit path, depending on case perimeter.
A tarp, plastic bin, generator box, shed, or improvised enclosure can restrict airflow, trap heat, interfere with exhaust, expose electrical areas, or create carbon monoxide risks. GenTent is engineered specifically as a portable generator running cover, not a storage cover or closed enclosure.
The goal is to protect the generator from weather while keeping the generator outdoors, ventilated, accessible, and properly positioned.
Start with your FIRMAN owner’s manual for generator operation, placement, fuel, maintenance, transfer switch, and CO Alert guidance. Then use GenTent installation resources and the Advanced Fit Finder to confirm the correct GenTent system for your exact FIRMAN model.
