Introduction
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

To reduce size and weight, the top, side panels and bottom
may be removed. Note: the next steps involve electrical
components and should only be done by a qualified
electrician.
1. Disconnect wiring in the back of the furnace: remove
access cover; unplug wires from snap discs; remove
temperature probe (use Allen wrench or Philips screw
driver); undo connectors on the blower wires; slip cord
strain relief out of its mount.
2. Remove 4 bolts from the top panel. Lift front slightly
to remove the switch trigger bolt, and then fully remove
the top panel. (Note: if switch trigger pulls out of the
control box, follow these instructions to re-install the
switch trigger: remove the control front plate to view the
inside of the control box; guide the switch trigger into
the 2 slots next to the limit switches.)
3. Remove the side panel: remove door lock bars and
front and back bolts; pull panel to the back until it can
pull away from the furnace.
4. Remove bottom: remove bolts and drop pan down.
5. To install components, reverse steps 1-4. Refer to page
8 and the electrical diagram on page 23 for assistance.

    cracks around windows and doors NORMALLY pro-
    vides adequate air for combustion and ventilation,
    and therefore no additional make up air is required.
5. For a ‘confined’ space or an ‘unconfined’ space in a
    building with unusually tight construction, an addition-
    al source of make up air is required. Please consult a
    HVAC professional to determine the best way to supply
    make up air for this type of installation.
Important: Furnace room must never be in a negative
    pressure condition. Negative pressure could result in
    smoke in the room.
Water Line Hookup
1. Hook up supply to “Supply” port and return to “Return”
   port as indicated (see page 8).
2. Install shut off valves on all lines attached to the fur-
   nace to prevent loss of water during maintenance and
   repairs.
3. The water circulating pump must be installed on the
   supply line and positioned below the supply port.

To maintain optimal performance:
1. Do not leave loading door open for extended periods of

2. Do not force the loading door open beyond the stop.

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.

1. Thoroughly clean the exhaust area, secondary burn
   chamber, and flues of any loose or crusted ash
   buildup. Crusted ashes are easier to remove when
   furnace is still warm. Note: a thin black coating in the
   firebox is acceptable, but ensure that there is no ash

2. Check for damaged brick and replace as necessary.
   Contact your dealer for replacement brick.
3. Check to ensure there is no moisture in any part of
   the inside of the firebox, secondary burn chamber,
   or exhaust area. Apply a thin film of oil in the flue
   area and exhaust area.
4. Chimney must have a rain cap.
