PUREHEAT™ HYDRONIC AIR HEATER OPERATOR’S MANUAL – SECTION 4

4.5 SUMMER STORAGE INSTRUCTIONS

1. Allow the heater to cool sufficiently. Cover the chimney and the Burner with plastic wrap or other

waterproof material. This will prevent corrosive moisture build-up and blockages caused by animal

nests. Burners not installed should be stored in a cool, dry place.

2. Remove emergency break-away battery and store the battery in a cool, dry place. Connect the

battery to a trickle charger once every 30 days to maintain full charge.

3. Perform a thorough inspection for leaks, and correct. Double-check that all valves are shut.

4. Ensure all manifold Quick-Connect covers are in place and secured.

5. Shut and lock all doors.

6. Protect the tires from direct sunlight if stored outdoors.

NOTE: Do not drain the HTF. The heater and plumbing must remain flooded with HTF to prevent

corrosion (rusting).
