PUREHEAT™ HYDRONIC AIR HEATER OPERATOR’S MANUAL – SECTION 3
BURNER ADJUSTMENT AND SHUTDOWN
The Pureheat™ Hydronic Air Heater can be operated on natural gas (NG), liquid propane vapor (LP) or
diesel/fuel oil (OIL). (Refer to Appendix A-24 or A-25 for Burner component identification)
NOTE: All Burners on Pureheat™ are initially calibrated (adjusted) by test firing at Ground Heaters, Inc.’s
factory located 600 ft (180 m) above sea level (asl) using NG/LP or a 70/30 blend of#2 and #1 (K1)
diesel along with additives.
For NG and LP Burners: The air and/or gas settings are returned to “zero” after factory test firing.
A CERTIFIED AND LICENSED GAS TECHNICIAN MUST RECALIBRATE THE BURNER AIR AND
FUEL SETTINGS TO OBTAIN PROPER COMBUSTION AT YOUR WORK SITE.
1. Burner setup and installation, fuel supply connection, test-firing and Burner adjustment must be
performed by a licensed professional and must conform to the requirements of local, state
and federal authorities. In the Commonwealth of Massachusetts, gas piping shall be installed
by a licensed plumber or gas fitter.
2. All gas and propane connections must be leak tested prior to placing into service.
3. The Pureheat™ must not be installed within 12 ft (3.6 m) of combustible materials.
4. All NG/LP Burners are test fired at Ground Heaters, Inc.'s factory prior to shipment.
To ensure proper Burner performance and to avoid machine downtime due to heater sooting, Burner
combustion verification and adjustment must be performed:
•
•
•
•
•
•
•
before starting at a new job site
before operating at elevations 1,000 ft (305 m) above or below the last adjustment
after any Burner maintenance has been performed
after changing fuel from NG to LP or LP to NG
after removing oil Burner and installing gas Burner
after removing gas Burner and installing oil Burner
if Burner performance is in question for any reason
A Combustion Analyzer, Smoke True Spot Tester, Fuel Pressure Test Kit (oil), Low and High range
Manometers (NG/LP) and common hand tools will be required.

NATURAL GAS/LIQUID PROPANE
3.1.1
Burner Adjustment
Before beginning these steps, it is assumed that the NG/LP Burner and gas train have been installed per
Section 4.2.2.
NOTE: The use of a high quality combustion analyzer and two manometers, one with a range of 0 to 15 in.
water column [WC] and one with a range of 0 to 30 in. WC is mandatory. All adjustments must be
accomplished by a licensed professional and must conform to the requirements of local, state and
federal codes and authorities.
Use air damper settings and fuel pressure adjustments to obtain an Exhaust O2 value of 3 to 5% and a
smoke spot value of 1 or less. Maintaining O2 in the 3 to 5% range assures that there are no unburned
hydrocarbons remaining in the exhaust. Unburned hydrocarbons cause soot production.
If the above values cannot be obtained by adjusting the Burner air dampers alone, it may be necessary to
reduce the firing rate (lower fuel pressure). This is especially true at elevations above 3,000 ft (914 m).

4.3
HIGH ALTITUDE OPERATIONS
1. The following procedures are recommended when operating the Pureheat™ at altitudes higher than
5,000 ft (1,524 m) asl. These procedures keep the Pureheat™ running smoothly and prevent the
possibility of premature soot build-up inside the hydronic heater fire tubes. ALL PROCEDURES
LISTED BELOW SHOULD BE PERFORMED BY CERTIFIED PERSONNEL AT YOUR GROUND
HEATERS DISTRIBUTOR.
2. When operating the Pureheat™ at high altitudes, the hydronic heater should be checked every 500
hours for sooting or other combustion abnormalities. Combustion Analyzer and Smoke Spot Tester
must be used for this test.
3. In addition to air adjustments, fuel pressure may be reduced to a lower pressure. To decrease fuel
burning rate, refer to Section 3, BURNER ADJUSTMENT AND SHUTDOWN for fuel pressure
adjustment instructions.
NOTE: Always verify Burner exhaust O2 and smoke levels after completing any adjustments to fuel
pressure as directed in Section 3.1.1, Gas Burner Adjustment or 3.2.1, Diesel Burner Adjustment.
4.4
RECOMMENDED FUELS
1. Pureheat™ Hydronic Air Heaters are typically used outdoors, in cold weather.
!
Care must be taken in selecting a fuel blend which will work properly in your jobsite
conditions.
2. Diesel fuel will thicken (gel) at low temperatures. Gelling (also known as waxing) may cause the
Burner not to light and/or fuel pump damage.
3. Contact your local fuel supplier to obtain potential gelling temperatures for your fuel, as specifications
for diesel fuel vary from terminal to terminal. Some fuel suppliers may add products such as
ValveTect to prevent gelling or Diesel 911 after gelling has occurred. Your fuel supplier should
supply this information and make recommendations for the selection and use of such products.
4. If ambient temperatures are such that your fuel supplier cannot insure the fuel will not gel, K1
Kerosene or #1 diesel fuel (dyed K1 for off-road use) must be added by ratio until gelling does not
occur.
5. Refer to the Fuel Blend Guide, below; consult your fuel supplier for assistance in calibrating these
values to your fuel.
DIESEL FUEL SELECTION
Low overnight ambient air temperatures can cause diesel fuels to gel.

PUREHEAT DIESEL BURNER CONTROL
SEQUENCE OF OPERATION AND LOCKOUT
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, output 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 for 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 elapsed, 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 fuel 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
