Starting Heater
1. Turn the power switch to the ON (I) position to start the fan.
NOTE: Before heater ignition, always allow heater fan (blower) to run for 20
seconds to purge fuel.
2. Slowly open the main valve at propane cylinder.
3. Push the gas valve button and push the ignitor (piezoelectric lighter) repeatedly
until the flame lights up.
4. After the heater lights, keep the valve button pushed for approximately 10
seconds. Should the heater stop when the valve button has been released, wait
one minute and repeat the starting operation, keeping the valve button pushed for
a longer time.
5. On the DXPH125E model only, rotate the control knob to the lowest setting. After
the heater lights, you may adjust the burn rate by setting the control knob to
desired level.
NOTE: Contact your supplier should any problem continue.
CAUTION: If ignition is difficult or irregular before repeating the starting steps,
make sure that the fan is not locked and the air inlet and outlet are unobstructed.
Stopping Heater
1. Securely close valve on the propane cylinder.
2. Continue to operate heater until all fuel in the hose has burned then turn power
switch to the OFF (O) position.
3. Unplug the power cord.
CAUTION: Always shut off fuel supply:
Before disconnecting electrical power
Before moving the appliance
After each use
RESTART AFTER SAFETY SHUTDOWN
1. Securely close valve at propane cylinder. Unplug power cord.
2. Wait 5 minutes.
3. Restart following "START" procedure.
NOTE: If a new tank has just been connected, please allow at least one minute or
more for the air in the gas pipeline to purge out through the pilot hole.
WARNING: Always keep a dry chemical fire extinguisher readily available.
FAN OPERATION
1. The appliance may also be used as a fan.
2. In this case remove the gas supply hose and connect the plug of heater to a
suitable electrical supply.
3. Set the power switch to the ON (I) position.
REPLACING THE GAS CYLINDER
1. Shut off the heater.
2. Close the valve of the gas cylinder.
3. Disconnect the regulator from the cylinder following the instructions that came
with your regulator.
4. Replace the cylinder.
WARNING: Only remove the plug or seal cap from the cylinder valve and
change the gas cylinder in a amply ventilated area, away from any ignition source
(candle, cigarettes, and other flame producing appliances).
5. Check for the presence and good state of the gasket before connecting the
regulator to the new cylinder.
6. Check that the regulator seal is correctly fitted and able to fulfil its function.
7. Perform leak test using soapy water solution.

Maintenance

• The heater should be inspected before each use, and at least annually, only by
a qualified person. Before starting any maintenance operation on the heater,
disconnect from both gas and electrical sources.
WARNING: The whole gas system. hose, regulator, pilot and burner should
be inspected for Ieak before use. But at least once a month and each time the gas
cylinder is changed. Check the hose assembly for sign of extreme abrasion, cuts
or wears. Suspected areas should be Ieak tested. If the hose Ieaks, it must be
replaced with a new one that conforms to IocaI standard codes). If it shows signs
of cracking, splitting or other deterioration it shall be exchanged for new hose of
the same length and of the equivalent quality. Replace the gas tube/hose within
the interval described with the hose.
If the unit has not been used for a long period we advise that a technician carries out a
general check up before using. It is important to perform the following:
1.
Periodically check the gas supply hose conditions and, should it be changed,
use only original spare parts.
2.
Check the connections of the safety thermostat and of the thermocouple: they
must always be clean. If necessary clean the fan blade and the inside of the
heater using compressed air.
