Propane pressure drops when a generator starts because fuel demand rises suddenly. Learn how tank size, regulators, piping, temperature, and restrictions cause pressure loss.

A propane generator that loses power under load usually has a fuel-flow, regulator, tank-vaporization, air, ignition, or overload problem. Learn what to check.

Quick Answer: If your propane generator surges or hunts—meaning the engine repeatedly speeds up and slows down—I usually look for an unstable air-fuel mixture or unstable governor response. On propane, common causes include low or fluctuating fuel pressure, a restricted or undersized regulator or hose, a sticking demand regulator, low tank vaporization, air leaks, incorrect

Quick Answer: If your dual-fuel generator runs normally on gasoline but will not start on propane, I focus on the propane side of the fuel system. The most common causes are an empty or weak propane cylinder, a cylinder valve that is closed or not fully open, an incorrectly connected regulator hose, the wrong fuel-selector

Quick Answer: If your propane generator starts and then dies, I usually check fuel supply and propane pressure first, then oil level/low-oil shutdown, overload or output faults, engine temperature, ignition, and the regulator/fuel solenoid. A generator may start on the small amount of propane already in the mixer or fuel line, then shut down seconds

Quick Answer: A standby generator does not have one universal propane regulator size. I size the regulator from the generator’s required inlet pressure and full-load propane consumption. Many residential standby generators need roughly 10–14 inches water column at the generator inlet, depending on the manufacturer. For a 14-kW or 16-kW unit, full-load propane demand is

Quick Answer: For a typical residential propane furnace and water heater, I usually look for a low-pressure second-stage regulator or an integral two-stage regulator that supplies about 11 inches water column (11″ w.c.) to the building gas system and has enough BTU capacity for both appliances operating at the same time. For example, a 100,000

Quick Answer: To calculate the total BTU load for a propane regulator, I add the BTU/hr input rating of every propane appliance that the regulator may have to supply at the same time. For example, if a furnace is rated at 100,000 BTU/hr, a tankless water heater at 199,000 BTU/hr, a range at 65,000 BTU/hr,

Quick Answer: Fisher, RegO, and Marshall Excelsior (MEC) all make serious propane regulators for residential, commercial, and specialty LP-gas systems. “RV-style regulator” is different because it describes a compact regulator category—often an integral two-stage or automatic-changeover design—rather than one brand. If I am sizing a permanent house, generator, furnace, or high-BTU system, I compare actual
