Why Choose the GS-DUAL?

Connecting multiple propane tanks with the GS-DUAL allows propane to be drawn evenly from all connected cylinders instead of emptying one tank at a time. This balanced fuel delivery increases available vaporization, extends operating time, and helps minimize propane tank freeze-up during cold weather or high-demand operation.

The premium dual-stage regulator maintains a consistent 11″ W.C. outlet pressure, while individual shut-off valves allow each propane cylinder to be isolated without shutting down the entire system.

Professionally assembled using premium brass components, the GS-DUAL is built for years of dependable service.

Frequently Asked Questions (FAQ)

What is a dual-stage propane regulator?

A dual-stage propane regulator reduces propane pressure in two stages, providing a steady 11″ Water Column (11″ W.C.) outlet pressure to your appliance. This helps maintain consistent gas flow and reliable performance, even during periods of high propane demand or changing weather conditions.

---

What is a propane manifold?

A propane manifold allows multiple propane cylinders to be connected together so they can supply fuel to a single appliance or gas system. The GS-DUAL manifold draws propane from all connected tanks simultaneously, increasing available fuel capacity while helping improve vaporization and reduce tank freeze-up.

---

Why should I connect multiple propane tanks together?

Connecting multiple propane tanks increases available propane capacity, extends run time, and distributes fuel demand across all connected cylinders. This balanced fuel draw helps improve vaporization and may reduce the chance of propane tank freeze-up during cold weather or high-demand applications.

---

Does this manifold automatically switch between propane tanks?

No. The GS-DUAL is an equalized propane manifold, not an automatic changeover regulator. All connected propane tanks supply fuel simultaneously rather than switching from one tank to another after it becomes empty.

---

What outlet pressure does the regulator provide?

The included dual-stage regulator delivers a nominal outlet pressure of 11″ Water Column (11″ W.C.), which is the standard low-pressure operating pressure required by most propane appliances.

---

Is this a low-pressure propane manifold?

Yes. The GS-DUAL is a low-pressure propane manifold that includes a dual-stage regulator delivering 11″ W.C. outlet pressure. It is designed for appliances that operate on standard low-pressure propane.

---

What size propane tanks can I use?

The GS-DUAL manifold is compatible with several common propane cylinder sizes depending on the POL connection selected.

• Handwheel POL: Fits propane cylinders up to 40 lb.
• Thumbwheel POL: Fits 20 lb. propane tanks and larger.
• HEX POL: Fits 20 lb. propane tanks and larger and requires an adjustable wrench for installation.

---

What is the difference between the Handwheel, Thumbwheel, and HEX POL fittings?

All three POL connection styles perform the same function. The difference is how they attach to the propane cylinder.

Handwheel POL

• Fits propane cylinders up to 40 lb.
• Hand-tight installation—no tools required.

Thumbwheel POL

• Fits 20 lb. propane cylinders and larger.
• Hand-tight installation—no tools required.

HEX POL

• Fits 20 lb. propane cylinders and larger.
• Requires an adjustable wrench for installation.
• Ideal for permanent or commercial installations.

---

Can I connect two 100 lb. propane tanks together?

Yes. The GS-DUAL propane manifold can be used with larger propane cylinders when equipped with the appropriate POL connections and hoses. Always verify that your installation complies with local codes and your appliance manufacturer’s requirements.

---

Can I use different size propane tanks on the same manifold?

For the best performance, we recommend using propane cylinders that are the same size and filled to similar levels. Matching tanks helps maintain balanced fuel delivery and consistent vaporization.

---

Can I choose between rubber and stainless steel braided hoses?

Yes. The manifold hoses connecting directly to the propane tanks are available in your choice of:

• Heavy-Duty Black Rubber Hoses
• Stainless Steel Braided Hoses

Stainless steel braided hoses provide additional protection against abrasion and are ideal for demanding environments.

---

Is the outlet hose stainless steel?

No. Every GS-DUAL manifold includes a 3/8″ Black Rubber Outlet Hose that connects the regulator to your appliance.

The outlet hose is always a 3/8″ black rubber hose, regardless of which manifold hose option you choose.

---

Are shut-off valves included?

Yes. Each propane tank connection includes its own brass ball valve, allowing individual propane cylinders to be isolated for maintenance or replacement without shutting down the entire system.

---

Does this manifold help prevent propane tank freeze-up?

Drawing propane from multiple cylinders spreads fuel demand across all connected tanks, improving vaporization and helping reduce the likelihood of propane tank freeze-up during high-demand operation or cold weather.

---

Can I replace one propane tank while the others remain connected?

Yes. Simply close the individual ball valve for that cylinder before disconnecting it. The remaining connected propane tanks can continue supplying fuel to the system.

---

Does this manifold come assembled?

Yes. Every GS-DUAL manifold is professionally assembled, leak tested, and ready for installation.

---

What appliances can this propane manifold be used with?

The GS-DUAL is commonly used with:

• Standby Generators
• Portable Generators
• Fire Pits
• Patio Heaters
• Outdoor Kitchens
• Food Trucks
• Commercial Cooking Equipment
• Construction Heaters
• Residential Propane Systems
• Agricultural Equipment
• Other low-pressure propane appliances requiring increased propane capacity

Always verify your appliance’s propane requirements before installation.
