KEEP THE VENT OPENING ON
TOP OF THE FURNACE CLEAR
OF ANY OBSTRUCTIONS.
IMPORTANT:
1. Use only soft, clean, filtered water in the Cozeburn.
Add Pro-Fab approved water treatment to the
water to prevent corrosion (available from your
Cozeburn dealer).
2. Add approved antifreeze to the water chamber to
prevent freezing should the furnace and the pump
shut down due to a power failure or other cause.
For amount of antifreeze to add follow instructions
on the container.
Use only environmentally friendly, propylene glycol
based, low toxicity, non-petroleum based antifreeze
designed for use in hot water furnace systems.
Available from your Cozeburn dealer.

First Fill

1. To fill the furnace with water from the inside of the
building being heated, install a plumbing "T" in the
return or supply line complete with a check valve and
boiler drain, see Figure 4.
2. Attach a garden hose, with two female ends, from the
water supply to the filler valve.
3. Isolate the furnace by closing off supply and return
valves securely at the back of the furnace.
IMPORTANT: The Cozeburn may need to be drained of its
contents at some time in the future. Be sure to place the line
fill/drain assembly in a location where water can easily be
drained and will not cause damage to the surrounding area.

4. Turn on the water to pressurize the line system and
check for leaks in the system.
DO NOT PRESSURIZE THE FURNACE.
5. CHECK ALL LINES AND CONNECTORS FOR LEAKS.
6. After checking for leaks in system, open the SUPPLY
valve at the furnace and let water run for 2 minutes and
then close it.
7. Now open the RETURN valve at the furnace and let
water run for 2 minutes and then close it.
8. Repeat above procedure 3 to 4 times during filling of the
furnace. Alternating between lines will ensure that most
of the air is bled from the system.
9. When the Cozeburn is full, shut off water and close the
in-line filler valve and disconnect the garden hose.
10. Mix Pro-Fab approved water treatment, with one to two
gallons of warm water and pour through vent opening,
Figure 3.

Maintaining Proper Water Level

When water level is low, the Cozeburn may be filled or topped
up through the vent opening, Figure 3.
