PREPARING FOR OPERATION
1. Check the heater for possible shipping damage. If any is found, immedi-
ately notify the factory.
2. Charge (Refer to Battery Charging Procedure Section) and insert battery
in the front of the heater or connect heater to 120 VAC on the back of
heater using an extension cord.
3. Follow all of the “Precautions”.
4. Connect the POL fitting of hose and regulator assembly to the propane
cylinder by rotating the POL nut counterclockwise into the propane cylin-
der’s valve outlet and securely tighten with a wrench.
5. Connect the hose to the heater by rotating the hose fitting clockwise.
6. Securely tighten all gas connections.
7. Slowly open the cylinder’s gas valve and check all gas connections
with a soap and water solution, looking for bubbles that would indi-
cate a gas leak. Note: if tank valve is not opened slowly, the excess
flow check valve on the propane tank may stop gas flow. DO NOT
USE A FLAME
8. Close propane cylinder gas valve.
START:
1. The DXH70CFAV heater is equipped with a blower fan switch, located
on the control panel of the heater. Press the on/off switch to start the
blower fan. Once the fan has been turned on, the green LED light on
the control panel will turn on solid, indicating that the fan is operat-
ing. The blower fan must be turned on before the gas/igniter valve is
pressed to light the heater. NOTICE: The fuel valve (black button)
has a safety lockout and cannot be depressed until 3 seconds
after the fan has been started.
2. Open propane supply valve on propane tank slowly. Note: If not
opened slowly, excess-flow check valve on propane tank will stop
gas flow. If this happens, close propane supply valve and open again
slowly. Wait 15 seconds before Step 3.
3. After the blower fan has been started, SLOWLY depress the black
gas/ igniter valve button located on the control panel to ignite the
heater. If the heater fails to light, release the black button and repeat
this step. Keep the valve depressed for 30-60 seconds, after burner
lights, then release and the heater will continue to operate. If the burn-
er shuts off, wait 20 seconds and repeat these steps.
NOTICE: This heater is equipped with a safety solenoid lockout that
prevents the gas valve being depressed until the heater is turned on
and the fan is operating. This system allows 15 seconds for ignition
attempts. After 15 seconds the heater must be reset for additional
attempts. To reset, press the on/off switch.
STOP
1. Press the on/off switch to turn off the heater.
2. Turn off the gas supply at the cylinder when heater is not in use.
LOW BATTERY VOLTAGE LOCKOUT
This heater is equipped with a low battery voltage lockout
that prevents operation if the battery voltage is too low.
FAN OPERATION MONITORING SYSTEM
This unit is equipped with a fan monitoring system. This system ensures that
the fan/blower is operating properly. If the LED indicator light is flashing an er-
ror code of 2-flashes. This is an indication that the fan is not operating properly
and service or adjustment is required. This can happen when
• Fan inlet blockage or contamination (drywall dust etc.)
• Fan locked rotor (something stopping the fan from rotating)
• Minimum RPM detected
• Failed fan component
• High winds or drafts
MAINTENANCE AND STORAGE
1. The heater should be inspected before each use, and at least annual-
ly by a qualified person.
2. Before each use, check the soft “O” ring seat at the bull-nose of the
POL fitting. If the “O” ring is cut, scuffed, or otherwise damaged,
replace it with part number F273786.
3. Turn off the gas at the LP-gas supply cylinder(s) when the heater is
not in use.
4. When the heater is to be stored indoors, the connection between the
LP-gas supply cylinder(s) and the heater must be disconnected and
the cylinder(s) removed from the heater and stored out of doors and in
accordance with Chapter 5 of the standard for Storage and Handling
of Liquefied Petroleum Gases ANSI/NFPA 58 and CSA B149.1, Natural
Gas and Propane Installation Code.
