Trench for Underground Pipes
1. The water lines
must be properly
insulated to
minimize heat
loss. Ask your
dealer for the right
underground water
line insulation.
2. Dig a trench, ideally
24” (61 cm) deep*
and 12” (31 cm)
wide, and make as
level as possible to
avoid damage to the tubing.
*Trench should be at least 36” (91 cm) deep under
driveways.
3. The water lines should be a minimum of 3/4”
(2 cm) inside dimensions*, rated and approved for use with
high temperature water and antifreeze.
*Size of water lines depends on distance; check with
a qualied heating professional to determine the line
size necessary to meet the demands of your specic
application.
Note: Size of piping must be such that excessive pressure
will not be developed in any portion of the boiler system.

Foundation Dimensions
1. The furnace should be installed on
a concrete pad.* Slope the pad 1/2”
(1.27 cm) towards the front of the furnace in order to drain
off any condensation that may accumulate in the ash tray.
*For furnaces without legs an option is to heighten the
pad for easier loading and ash tray removal.
2. If the soil is somewhat unstable, a good bed of crushed
rock or a grade beam, will help prevent the furnace from
shifting.

bottom forklift guides.
Use caution! Furnace is
heavy.
Once the unit has been
placed into position,
remove the back cover and the light globe from the rebox and
install.
Type “A” furnace requires a tight
silicone seal around the base to keep
out rodents, etc.
The furnace is now ready to hookup
the heater to the underground water
lines.
1. Install shut off valves on all lines
attached to the furnace to prevent
loss of water during maintenance
and repairs. Fittings and valves to
be attached to the furnace should either be stainless steel or
brass.
2. IMPORTANT: A spark arrester must be installed if the
Cozeburn Outdoor Wood Burning Furnace is used in a high
reriskarea.
3. The water circulating pump must be mounted in the hot
supply line several feet below the top of the furnace water
level to minimize air lock problems, see Figure 1, 2, or 3.
IMPORTANT: Pump must always be in lowest part of the line
system and horizontal with the ground, see Figure 4.
