two 47kg propane bottles.

Gas cylinders are heavy, never attempt to lift a

cylinder, full or empty, by yourself. Always get

help.

Keep cylinders upright at all times during use,

transporting and when stored.

Liquid gas can cause severe freeze burns so

avoid skin contact by wearing gloves when

making connections or handling the cylinder. If ice

is noted on the cylinder ensure it is not leaking. If

leaking is suspected do not use the cylinder.

4.2 Operating instructions

Ensure that you have read all other detail included

in these instructions prior to following the

operating instructions detailed below.

The heater can be operated on either a 110 or

230 volt electrical supply by inserting a suitable

connector/lead into either the 110 or 230 volt

appliance connectors.

Plug the supply lead into the connector on the rear

of the product.

Select the appropriate voltage.

Uncoil the hose from around the rear ring.

Attach the regulator to the gas bottle using the

spanner provided. Note Left hand thread.

Check for any gas leaks with soapy liquid solu-

tion .

Ensure the hose is not twisted or damaged and

that the gas bottle is positioned at the side of the

unit to avoid heating at the outlet.

Operating Instructions.

Note When positioning the heater please ensure

that all inlets and outlets are unrestricted there are

no combustible materials in the vicinity. Please

ensure the heated air is not directed towards the

gas bottle.

In dusty environments the fresh air

duct must be used. See section 4.

4.3 Thermostat Control

The temperature of the building can be controlled

using an optional remote thermostat. A remote

thermostat kit c/w 5 metres of cable is available

from Ambi-Rad by quoting part number 200587.

Select remote thermostat.

Plug the remote stat lead into the remote stat

socket.

4.3 Operation

After switching on the mains supply, ignition is

controlled by the automatic ignition unit

incorporated on the burner assembly.

Firstly you will hear the combustion and

convection fans running. ( Note - If the

combustion fan does not operate, then check to

see if the overheat stat reset has tripped. This is

located behind the combustion fan access door -

see 7.3)

Then, after a delay of 15-20 seconds, you will

hear a ‘Clicking’ noise, as the igniter assembly

attempts to light the gas. On ignition the amber

light will illuminate. If ignition does not occur then

the light turns off indicating there is potentially air

in the gas line.

Re-ignition can be attempted by restarting the ap-

pliance. If ignition still does not occur and the

lockout lamp illuminates, it is likely that the low

gas pressure switch is activated indicating that the

LPG bottles are exhausted of gas and require

changing. If after changing the gas bottles and

ignition still cannot be achieved, please refer to

section 8.1 Fault Finding.

4.4 Disconnection

Note Connecting and disconnecting cylinders

MUST take place in a flame free atmosphere.

When the appliance is not going to be used for a

period of time the unit MUST be disconnected

from the electrical mains and gas cylinder.

When heating is complete, turn OFF the gas

supply. Leave the electric supply turned ON to

enable the combustion fan to operate for 10

minutes to cool the product prior to moving.

After cooling is complete, switch the 3 position

rocker switch on the rear of the product to the

OFF position and disconnect from the electric

supply and remove the electrical connector.

Disconnect the gas supply and recoil the hose

around the rear ring assembly..

Note If the appliance is not to be used for a period

of time, ensure that the appliance is stored in a

dry environment.

5.0 Cleaning & Maintenance

The gas hose should be checked regularly for its

integrity, if any damage is found the hose must be

replaced. See Technical details for hose details.

Ensure that the air intakes and flue outlet on the

sides of the product are clean and free from any

blockage.

The casing can be cleaned with a soft cloth and a

mild detergent as required.

6.1 Ducted flue gasses

The products of combustion can be taken away

from the room where the product is being used by

the use of a flue duct.

To keep touch and floor temperatures to an

acceptable level, Ambi-Rad recommend a twin

wall flue pipe with a 108mm diameter capable of

withstanding 175°C. A total length of 10m must be

used.

Ambi-Rad can supply the 5m ducted flue kit by

quoting part no. 200584. A 5m extension kit is

also available by quoting part no. 200601.

Care must also be also taken by the user to

ensure that any potentially combustible materials

do not come into contact with the flue pipe.

A flue pipe connection is available from Ambi-Rad

to connect to the flue pipe on request.

Firstly, attach the front flue pipe section to the

product by pushing the flue duct spigot into the

flue outlet to ensure that the spring loaded flap

moves through 90° to close off the flue outlet to

the axial fan air stream.

Secondly, attach the rear flue pipe section at the

end of the front section as shown above. The

securing clip can now be tightened to keep both

sections together.

6.2 Ducted air

IMPORTANT In environments where

dust, moisture or fumes are present a

ducted air inlet is provided to allow

fresh air to be drawn into the burner to aid

combustion and prevent obstruction of the

burner with foreign objects. The tube feeding

the ducted air inlet must be 150mm diameter

and have a maximum length of 10 metres.

Ambi-Rad can supply a 5m ducted air spigot kit by

quoting part no 201847.

To fit the ducted air tube assembly push the

ducted air spigot into the connection point on the

side of the product as shown in the above photo.

6.3 Air delivery duct

A 450mm air delivery duct can be fitted to the

outlet spinning as shown using a suitable fixing

method. A material capable of withstanding 120°C

must be used.

Ambi-Rad can supply a 10m air delivery duct by

quoting part no 201848.
