Description

The Firman H03652 generator features 4550 starting Watts and 3650 running watts. Power is supplied by a Max Pro Series 208 cc engine which runs cool and efficient thanks to its Phoenix Fat Head Block. The Whisper Series muffler keeps the H03652 running at a quiet 67 decibels, well below the standards set by the National Parks Service, and the spark arrester has been approved by the USDA Forest Service. It runs on gasoline or propane fuel for increased flexibility while out on the road or during an emergency. The Firman Volt Lock automatic voltage regulator ensures clean, consistent power output from the Firman Power Stream alternator. The 8 never-flat wheels and the u-shaped padded handle with ergonomic grip make it an easily portable device. Pertinent information is at your fingertips with the 3-in-1 data minder measuring volts, hertz, and hours. Everything you need comes standard in the box including: oil, funnel, owner's manual, spark plug wrench, and two wrenches to remove protective shipping brackets.

Can this generator be connected & run on household natural gas & are correct couplers available ? thank you

Asked by: DLPoulin
Nothing in the manual says natural gas (methane) is acceptable. To convert to natural gas would probably require a different jet for a different fuel/air mix. It comes with a hose for propane tanks only.

Can the unit convert its orfice to natural gas?

Asked by: Mr Apple
Hi We don't offer a conversion kit for converting propane to natural gas. We have several customers who have purchased after market conversion kits. We have not done any testing on natural gas for this model we are not sure what the specs would be. Your Firman Friends

I like the dual fuel source feature. How clean is the electricity? Does this produce Sign Wave current as newer furnaces and water heaters require cleaner power? Will this generator produce that or is an inverter the better option? Thanks

Asked by: CJH4
HI, The THD on the unit is 25% we many customers in Canada that use this model to run there furnaces and water heaters. The THD on our inverters is 3%. Hope this helps. Your FIRMAN Friends

Considering buying this unit for my father in law who is just turning 80. Im worried about access during a storm. Can this unit be stored outside all year round? We live in eastern Ontario, so cold in winter and lots of snow. Should we cover it? Thank

Asked by: Steve in Ottawa
Yes, The generator can stay outdoors.It would be best to keep it covered. I recommend upgrading that model to an electric/recoil start model H03561. Hope this helps. Your FIRMAN Friends

How much fuel and propane does tanks hold  How long is running time for full propane tank and full gas tank

Asked by: Ray Brisson
Hi Ray, Model H03652 has a 5 gallon gasoline tank which will run 12-14 hours at 50% load. The propane run time depends on the size tank you have. Most customers use a typical 20LPG tank which you will get approx: 4-6 hours run time at 50% load. Hope this Helps. Your FIRMAN Friends

Firman Hybrid Series Portable Generator - Gas/Propane - 3650 W is rated 4.6 out of 5 by 39.
Rated 5 out of 5 by from Just what we needed! We ordered this generator in preparation for Hurricane Florence. Out of the box, it was easy to set up and the instructions are very straightforward. I haven't used the propane side of it, but the gas side works great and lasts over 14 hours on a full tank. Tropical Storm Michael came through last night, so I'm actually using the generator right now. I have no complaints so far. I would recommend purchasing a large 5-gallon gas can and extension cords to go along with it. I'm using a 2-gallon can, which means multiple trips to the gas station. Right now I have a deep freezer, a refrigerator, wireless router and multiple wireless devices drawing power. Highly recommended.

Rated 4 out of 5 by from Impressed and a definitely a great buy! My primary reason for purchase was for wildlife camping. Easy to start. A 5 gallon of gas will run for a good 13-14 hours which in my book a big thumbs up! You don't have to worry about filling gas mid-night. This thing has enough power to run air condition, lights, hair dryer and coffee machine, the works. Dual fuel is a definite plus if you run out of gas, it's easy to hook up to your propane tanks. Runs very well on LP also. Used for home when Hydro went out and it was powerful enough to power the essentials. The only reasons I gave it a 4 stars is because of the weight and noise level. Hard to load in a truck. It's a 2 person lift. The noise level is borderline noisy, but I can deal with it because of the price difference between a less noisy generator, a $1,500-$2,000 difference. All in all a very great purchase.

Rated 5 out of 5 by from just right JUst put into service running small ac in my camper alot quieter than expected ac on high is louder setup was easy big surprise it started for first time on the first pull think i might just beat the texas summer heat while camping

Rated 5 out of 5 by from Duel Fuel twice as good Being able to use both gas and LP, make for a versatile unit! Starts easy, and is quit quiet for a job site gen.

Rated 5 out of 5 by from Excellent Power Got it out of box, filled fluids and removed red shipping supports and started right away. Let run for a couple minutes and plugged in RV, turned on AC, refrigerator, and microwave! WOW. Great buy for the price and quality...and just as quiet as 2 inverters working in parallel!

Rated 5 out of 5 by from noisey but powerful. con: 67db is pretty loud to me. I have considered making a sound abatement box for it, but decided against it due to venting and cooling issues leading to a possible warranty violation. The cost of the sound box would amount to the cost of the generator. So I will run it for the needed 5 hour break in period and periodic other times when we or a neighbor are mowing lawns. I bought it to use in times of emergency, so when we have an emergency, I think my neighbors will understand. pro: it starts easily. Although I haven't tested its total capacity nor used propane as the fuel, but will at some point. I like the idea of multi fuels. Propane to back up gasoline, I understand that propane keeps much longer than gas. the loading readings in amps is a great feature.

Rated 5 out of 5 by from Just what I wanted! Wanted a hybrid that can use propane. First thing I tried when I got this home is the propane feature. Worked good, ran for about 10 minutes. Now I can store in the house (generator), no smell, safer against theft. Already use propane in camper, grills, and other appliances. Live in hurricane plagued area. Hoping to have easier access to propane b4, during and after storm.

Rated 5 out of 5 by from Love the option to run this off LPG or Gas No more Carburetor issues, I've always got tanks of LP A/C, Fridge, Fireplace, Microwave, Flat Screen and my entire little pop-out outdoor kitchen - great generator - owned it almost 16 months- has 450 hours and not a single issue - its easy and dummy proof.
