MAINTENANCE
The Pureheat™ Hydronic Air Heater must be operated only with Ground Heaters Heat Transfer Fluid
.
(HTF)
The standard Pureheat™ contains 145 US gallons (535 liters) of HTF for normal operation. Ground
Heaters, Inc. recommends that the HTF be replaced every three years to ensure that the corrosion
inhibitors are sufficiently active to protect the system components.
4.1ADDING HEAT TRANSFER FLUID
(Refer to Appendix B-10)
NOTE: Shut down all pumps (including optional Booster Pump). (If using optional Booster Pump, refer
to Section 2.3.7, Optional Booster Pump.)
4.1.1 To Clear a “LOW LEVEL FAULT”
1. Place an open container of HTF close to the
manifold area to facilitate filling. The container
must be close enough to allow the 16 ft (4.9 m) fill
hose to reach the bottom of the container.
2. Power up the Pureheat™ as directed in Section
2.4, START UP.
3. Ensure that the PUMP and BURNER Switches
are OFF.
4. Ensure that a least one section of circulation hose
is connected to the supply and return manifolds to
complete a circulation loop.
5. Verify that valve #3 is shut.
6. Verify that valves #2 and #5 are open.
7. Pull out the fill hose (attached to valve #4). Clean the exterior and remove the fill hose dust cap.
4-1
8. Remove the locking pin from fill valve #4.
9. Direct the open end of the fill hose into the opening of the HTF container.
10. Momentarily open fill valve #4 until HTF is observed running out of the fill hose. This will “prime” the
fill hose.
11. Quickly close fill valve #4 to avoid over filling the HTF container.
12. Cover the open end of the fill hose to retain HTF after priming.
NOTE: If the HTF container height is such that it will not allow gravity flow from the Pureheat™ fill hose,
use a separate container with an opening low enough to facilitate priming the fill hose using the
method described.
13. Insert the fill hose into the HTF container, ensuring that the hose is not sealed against any interior
surface of the container.
14. Open fill valve #4. Immediately lift and hold the HTF FILL Switch to begin filling. (Photo 4-1)
15. Continue filling using the HTF FILL Switch until fluid is observed in the bottom of the sight gauge.
16. The LOW LEVEL RESET button may now be pressed to clear the low level shutdown condition. It is
not necessary to stop the filling process during this step. (Refer to Appendix B-10)
PUREHEAT™ HYDRONIC AIR HEATER OPERATOR’S MANUAL – SECTION 4
17. After the Low Level Shutdown device has cycled through a 15 second self test, the low level condition
will clear.
18. The PUMP Switch may now be turned ON, and the HTF FILL Switch released to finish filling.
19. Continue filling until the HTF level is between the MIN and MAX as observed in the HTF sight gauge.
Do
not over fill.
20. Once adequate HTF levels are verified in the Sight Gauge, remove the Fill Hose from the HTF
container but continue running the HTF pump. Elevate and outstretch the Fill Hose to clear excess
fluid from the hose.
21. Close fill valve #4 and insert the locking pin. Open Pump Suction Valve #3.
22. Clean the Fill Hose exterior and replace the dust cap. Stow the hose neatly in-between the HTF
Pump and the Supply/Return manifold rack.
NOTE: HTF Low Level Shutdown Device red (Low Water) light will blink for 15 seconds while device
performs self-diagnostic tests. After 15 seconds the red light will go out and the green light will
stay on, signaling the unit is ready to operate. The red LOW LEVEL FAULT light on the control
panel will also go out.

NORMAL SEQUENCE OF OPERATION:
Assuming a normal power up has been completed per Section 2 of this manual, the BURNER Switch is turned ON, the In-Line
Fuel Heater is energized and begins to warm the fuel in the Nozzle Assembly Tube. With a demand for heat, outpu t contacts 14
& 15 of the Temperature Control (TC) will close completing a circuit from L1 to the Burner Control Relay Coil (CR-2). Burner
Control Relay (CR-2) normally open contacts 6 - 8 will CLOSE completing a circuit between 3T & T of the burner control.
The Burner Control initiates a 5 second self diagnostic test followed by a non-adjustable 15 second valve on-delay period called
Pre-purge. During the Pre-purge cycle, both the Ignition Transformer and Burner Blower Motor are energized but fuel is not
allowed to flow past the Fuel Shut-off Valve. Once the pre-purge cycle is complete, the Fuel Shut-off Valve Solenoid Coil is
energized by the Burner Control and fuel flow is initiated to the Burner Nozzle. Once fuel flow has begun, a 10 second trial for
ignition period begins. During trial for ignition, the Ignition Transformer remains energized fo r an additional 10 seconds, this is
known as ignition carryover. Once flame is established and proven by a Cad Cell resistance value of more than 300 but less
than 1600 Ohms, the Ignition and the ten second trial for ignition time has ela psed, the Ignition Transformer is de-energized for
the duration of the heating cycle. Once the demand for heat has been satisfied, output contacts 14 & 15 of the TC OPEN
breaking the circuit to Burner Control Relay Coil CR-2. The now de-energized relay will OPEN Relay CR-2 contacts 6 - 8
breaking the circuit at 3T to T of the Burner Control. The Burner Control will shut off the fu el supply to the burner nozzle by deenergizing the Fuel Shut-off Valve Solenoid coil. The Burner Blower Motor will continue to run for 15 seconds (post-purge
cycle). The amount of time allowed for pre-purge depends on the Off-delay Dip Switch setting. Ground Heaters, Inc.
recommends the factory setting of 15 seconds off-delay. Several delay settings are available as detailed on the front of the
burner control.
BURNER FAULT:
If the Cad Cell senses an absent or unstable flame at any time during the heating cycle, the Burner Control immediately shuts
down all Burner functions and enters one of three protective modes (BURNER FAULT). BURNER FAULT is identified by the
Diagnostic Light (see photo below) and indicated by illuminating the BURNER FAULT Light (main control panel) simultaneously.
The three BURNER FAULT or Lockout modes are described in detail below.
1. RECYCLE MODE
:
The DIAGNOSTIC Light will flash in two second intervals while attempting three automatic restarts. If the flame fails after three
successive attempts, the control will enter Lockout Mode.
2. LOCKOUT MODE
:
The DIAGNOSTIC Light will flash in ½ second intervals. The RESET button must be momentarily pressed to clear the Lockout
and attempt a Burner restart. After the third attempt to manually clear the Lockout mode, the Burner Control will begin
Restricted Lockout Mode.
3. RESTRICTED LOCKOUT MODE
:
The DIAGNOSTIC Light will flash in ½ second intervals. The RESET button must be pressed and held until the DIAGNOSTIC
Light comes on momentarily and then goes out. The Burner Control will return to Restricted Lockout Mode with each flame
failure until one successful heating cycle has occurred.
