PUREHEAT™ HYDRONIC AIR HEATER OPERATOR’S MANUAL – SECTION 1

INTRODUCTION

The Pureheat™ Hydronic Air Heater provides temporary air heat, thaws frozen ground, cures concrete

and provides frost prevention at ambient temperatures below 40°F (5°C). Ground Heaters, Inc.’s

revolutionary technology enables construction activities to continue throughout the cold weather months.

The Pureheat™ Hydronic Air Heater is equipped with a 5-Port On-Board Manifold and 1,000 ft (396 m) of

1 in. (25 mm) ID Red Circulation Hose Assemblies with Quick-Connects (QCs). The standard equipment

package includes the following lengths of Circulation Hoses: Two (2) 200 ft (61 m), Four

(4) 100 ft. (30 m ),

Four (4) 50 ft (15 m)

. The optional diesel or gas Burner heats the Heat Transfer Fluid (HTF) to 180°F

(82°C). The HTF is continuously circulated through the Circulation Hoses in a vented, closed-loop

system.

With standard equipment, the Pureheat:

(Refer to Appendixes B and C)

• Provides remote space heating for up to 1,200,000 ft

3

(48,235 m

3

) of building space.

Using GHI’s optional Booster Pump and Auxiliary Pump Panel, Three (3) Hose Handling System 3004

(HHS3004) with Twelve (12) 750 ft (228 m) 5/8 in. ID Heat Transfer Hoses (HTH) and three 4-Port

Remote Manifolds, the Pureheat will:

• Thaw

up to 18,000 ft

2

(1,674 m

2

) of frozen ground per application using 24 in. (60 cm) hose

spacing.

• Thaw

up to 9,000 ft

2

(837 m

2

) 75% to 100% faster using 12 in. (30 cm) hose spacing

Using GHI’s optional Booster Pump and Auxiliary Pump Panel, Five (5) Hose Handling System 3004

(HHS3004) with Twenty (20) 750 ft (228 m) 5/8 in. ID Heat Transfer Hoses (HTH) and Five (5) 4-Port

Remote Manifolds, the Pureheat can:

• Cure

all types of concrete placements, including slabs on grade, elevated slabs, tilt-up walls,

poured walls, columns, footings, bridge decks, etc. up to 30,000 ft

2

(2,790 m

2

) per application

using 24 in. (60 cm) hose spacing.

• Provides Frost Prevention

up to 45,000 ft

2

(4,186 m

2

) per application using 36 in. (91 cm) hose

spacing.

The Pureheat™ Hydronic Air Heater Model Pureheat:

• Heats

workspace easily & economically:

• Input of 860,000 BTUH.

• Fuel flexible; choice of natural gas, propane or diesel.

• Takes only minutes to change over from one fuel to another.

• Provides pure, dry, hot air

– no moisture added to workspace; prevents mold and mildew.

• Removes excess moisture

– dry / warm air removes moisture from workspace and building materials.

• Provides pure, clean air

– no combustion by-products in workspace.

• Is self-contained

– all system components are on One (1) trailer.

• Is rental friendly

– easy setup and uses only One (1) 15 amp. And One (1) 20 amp. 120 volts AC

circuits.

• Is multi-functional

– with accessories, this system can be used as a surface heater.

: operates at zero (atmospheric) pressure.

3. Low Level Shutdown Device

: turns off the Burner and Pumps if HTF level in the system drops below

minimum operating level. Manual reset requirement prevents unsupervised Pump/Burner start up.

4. Ground Fault Interrupters (GFI)

: built into control panel to protect all circuits.

5. Circuit Overload Protection

: built into Main Control Panel to protect all circuits and components.

6. Burner Flame Monitoring

: Burner Control uses optic flame sensor to shut off Burner if flame fails to

ignite or upon loss of flame. Manual reset requirement prevents unsupervised restart.

7. Pump Motor Overload Protection

: internal thermal overload trip with automatic reset.

8. Burner Motor Overload Protection

: internal thermal overload trip with manual reset (diesel Burner

Motor only) and internal thermal overload trip with automatic reset (NG/LP only).

9. Reflective Markers

: enhance night identification.

10. Foot Pedal

: for Hose Rewind system wired with low voltage (12 VDC) signal to protect personnel

from shock hazard should the Foot Pedal become accidentally immersed in water.

11. Digital Temperature Control

: fails safe (Burner OFF) upon loss of power or temperature sensor

malfunction

12. System Over Temperature Backup Shutdown

: Bi-metal snap disc will shut down the Burner Blower

Motor should HTF temperature exceed 200°F.

13. Natural Gas (NG) / Propane (LP) Burner

:

a. Ten (10) Second Pre-Purge Timer

b. Automatic Burner Sequencing

c. Flame Monitoring

d. System Status Indication

e. System / Self-Diagnostics

f. Post-Purge Timer

g. Pilot Valve / Ignition

h. Infrared Flame Detector

i. Air Flow Proving Switch
