The multi pass series

The cutting edge outdoor furnace to keep you warm

Highlighted Furnace Features

TRIPLE PASS WATER FILLED HEAT EXCHANGER

The triple pass water filled heat exchanger was developed to allow for better heat transfer and higher efficiency than conventional units. The heat exchanger is strategically placed within the water jacket which increases the heat recovery when compared to the Shaker Grate Series.

The Multi Pass Series features a Heat Exchanger Cleanout Door, accessible from the front of the outdoor furnace, for ease of cleaning fly ash.

SHAKER GRATES & ASH PAN

The Multi Pass series features our Original Cast Iron Shaker Grate & Ash Pan system. Our Shaker Grates aid in the optimization of air flow under the fire, while at the same time allowing the owner to quickly shake out excess ash without the use of special tools. The ash is collected in the provided extra large, removable, ash pan, making cleaning and disposal extremely easy. Just like the Firebox Door, the Ash Pan Door features our double safety latch handle.

ADJUSTABLE PRIMARY AIR BLOWER

The introduction of combustion air under the Shaker Grates assists in increasing the fire temperatures, making the burn more efficient and cleaner compared to other conventional units on the market. The Adjustable Primary Air Blower ensures there is always the proper amount of air flow inside the firebox at all times, no matter the type of fuel being burned. The combustion air is controlled by a variable speed nob, conveniently located on the Control Panel.

EXTRA LARGE, INSULATED, FIREBOX DOOR

We designed the Multi Pass Series of outdoor furnaces to feature an extra large firebox door, placed at the optimal height for care free loading. Safety is at the core of everything we develop which is why all of our firebox doors have multiple layers of insulation and are equipped with our roller latch door system.

Other Furnace Features

409 Titanium Enhanced Stainless Steel Firebox & Water Jacket

Developed to withstand the high temperatures of gasification, 409 Stainless Steel provides the best corrosion resistance, maximum heat transfer and strength needed for the firebox and water jacket.

Shaker Grate

The shaker grate design allows for easy and clean burns and ensures a complete burn of your coal. The automatic forced air blower extends burn time and creates greater efficiency with hotter burns by introducing air under the grate.

Removable Ash Pan

The extra large Removable Ash Pan enables easy cleaning while the large ash pan door allows for easy access.

Ultra-Temp Insulated Stainless Steel Chimney

Stainless steel inner and outer shell for added durability. Double wall insulated chimney allows the chimney to be easily expandable, with interlocking lengths available.

Turbo Draft System

The turbo draft system allows for a cleaner, more efficient burn inside the firebox while permitting secondary gases to be burned before escaping out of the furnace chimney.

Water Level Indicator

Easy to read water level indicator will keep you informed when additional water must be added.

Easy to use Controls

The Multi Pass series is thermostatically controlled to offer an even heat throughout your home or business. Our digital illuminated controls are easy to read at all times. Due to their designs they are also economical and easy to replace.

Triple Pass Water Filled Heat Exchanger & Stainless Steel heat Exchanger Tubes

The Triple Pass system allows the Multi Pass stoves to have better heat transfer with higher efficiency and lower fuel consumption rates. It also facilitates secondary combustion while enabling faster heat recovery.

Cost Savings

Crown Royal Stove owners can save approximately 50% – 100% of their annual heating costs. They may also Reduce or even eliminate hot water bills and the dependence on foreign fuels.

Convenience

Depending on the outdoor temperature and size of the unit, our outdoor furnaces only need to be loaded once or twice a day. Since our units are installed outdoors it eliminates dirt, bark, ash, smoke, soot, or insects from inside your home that may have otherwise been there if an indoor unit were installed. It now stays outside where it belongs. With proper installation requirements you may also melt away snow from driveways and sidewalks.

Manufactured with Safety in Mind

With an outdoor stove you eliminate the risk of a house fire, chimney fire, indoor smoke, or carbon monoxide poisoning. Our unique Firebox Safety Latch System prevents the loading door from swinging open too quickly. Each Crown Royal Stove has been rigorously tested to ensure a durable, dependable furnace.

Turbo Draft System

Assisting in ensuring each burn cycle is cleaner and more efficient, the Turbo Draft System introduces fresh air above the flame, forcing secondary gases downward to be burned before making their way into the triple pass heat exchanger. When secondary gases are ignited temperatures of the fire drastically increase making the burn more efficient, simultaneously increasing heat recovery, all while lowering the possibility of creosote buildup from gases that escape up the chimney.
