INSTALLATION INSTRUCTIONS
GAS SUPPLY
Your heater is fitted with a flexible hose and bayonet coupling which enables you to connect or disconnect
it from the gas supply.
ONLY USE THE HEATER WITH THE CORRECT GAS TYPE IT WAS DESIGNED AND ADJUSTED TO.
IF IN DOUBT, CHECK WITH YOUR LOCAL GAS SUPPLIER.
CONNECTING TO GAS SUPPLY
TO DISCONNECT
Apply firm forward pressure to the knurled area, rotate anti clockwise and pull towards you. The hose
should now come away from the wall bayonet fitting. Gas is automatically isolated when the hose is disconnected.
ELECTRICAL SUPPLY
Your heater is fitted with a power supply lead, which should be connected to a standard earthed domestic socket
outlet.
ABNORMAL OPERATION
As the heater heats up or cools down, expansion or contraction takes place and the occasional
‘click’ may be heard. This is normal, however, continuous metallic noises, grinding sounds, the smell of
gas or any of the symptoms listed on the fault finding chart should be investigated immediately. Turn the
appliance off and disconnect the gas and electrical supplies. If the fault cannot be fixed or any doubts
exist, contact your nearest OMEGA ALTISE service agent or contact OMEGA ALTISE on the telephone
number on the rear page of this booklet.
NOTE:
When using the appliance for the first time or after long periods of disuse or storage, ignition may not occur the first
time it is operated as there may be air within the gas supply line. If ignition does not occur after approximately
12 seconds the unit will cease operation automatically and may show an error code E2 or E12. If this occurs press the
ON/OFF button twice to restart. For models that are equipped with a remote control, press the OFF button and then
press the ON button to restart.
If the error continues to occur after 2-3 attempts, consult the troubleshooting guide on page 11
The bayonet plug on the factory fitted flexible hose simply
plugs into your home bayonet fitting by pushing and
rotating 1/4 turn clockwise.
