The Crown Royal Pristine Series Hot Water Furnace
You have selected one of the best wood stoves/furnaces on the market
today! It has been specially designed to produce highly efficient heat with
emissions well below environmental standards, and we are proud to offer
a 10 year limited warranty!
To ensure maximum benefit from your new Pristine furnace, read the
Installation and Operation Instruction Manual cover to cover and follow all
instructions carefully.
The Pristine furnace has been designed for indoor installation and has
also been tested to meet UL Standard 391 - 2006 Standard C22.2 No.3
and CSA B366-1-M91 for indoor central solid fuel fired furnaces.
Please keep this manual for future reference.
Crown Royal Pristine
Series MODEL 1000
How The Pristine Furnace Works
The Pristine uses a process called wood gasification to
produce highly efficient combustion in the furnace’s dual
burn chambers. (1) Wood in the firebox burns from the
bottom up, drying the top layer of wood in the firebox and 4
forcing gases and exhaust into the lower burn chamber. (2)
In the brick-lined lower chamber, these volatile gases are
burned at temperatures as high as 2000°F (1093°C).*
The fire brick lining in both burn chambers absorbs the heat
and maintains burn chamber temperatures for consistent 3
1
gas combustion. This high-temperature gas combustion
significantly lowers emissions, prevents creosote buildup,
and minimizes ash buildup in the unit. (3) After passing
through the burn chamber, exhaust air escapes through
multiple flues running through the water jacket, heating
the water quickly and efficiently. (4) The exhaust cools as it 2
passes through the flues, and when it leaves the chimney,
temperatures have fallen to 350°F (177°C).
*varies based on fuel type, burn rate and other conditions

2. Install shut off valves on all lines attached to the fur-

repairs.
3. The water circulating pump must be installed on the

Power Outages
The Pristine furnace, unlike a gas or oil fired appliance,
does not stop generating heat when the power is
interrupted even though the blower automatically shuts off
causing the fire to die down. As a result the heat transfer
fluid in the furnace may overheat and boil off through the
vent. When power resumes be sure to check the fluid level.
