BRIEF DESCRIPTION
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: IT IS A STATUTORY REQUIREMENT THAT ALL GAS APPLIANCES BE
INSTALLED BY COMPETENT PERSONS, (i.e. GAS SAFE REGISTERED INSTALLERS.
GAS SAFE MEMBERSHIP ENQUIRIES - TEL: 0800 408 5500) IN ACCORDANCE WITH
THE GAS SAFETY (INSTALLATION AND USE) REGULATIONS (CURRENT EDITION).
FAILURE TO COMPLY WITH THESE REGULATIONS MAY RESULT IN PROSECUTION.
1.1
The WarmCair unit is a highly efficient condensing gas-fired (forced either downflow or
upflow) air heater. Significant reductions in Carbon and NOx emissions are achieved.
1.2
It has been designed to provide the user with on demand Warm Air Central Heating, using sophisticated
controls and enabling it to provide the precise amount of heat output to match demand. It is room
sealed, with a corrosion free stainless steel heat exchanger, using a vertical or horizontal Concentric
Flue System.
1.3
The WarmCair air heater is ideally suited for new built dwellings and the replacement of existing non-
condensing air heaters.

MODULATING CONTROL - HOW IT WORKS
2.1
Modulating Control automatically operates your heating system to maintain winter comfort efficiently
and unobtrusively.
2.2
You select the comfort level by setting the temperature controller (OpenTherm controller).
2.3
The amount of heat needed depends upon the difference between the temperature outside the
dwelling and your chosen set temperature. The system automatically adjusts its warm air output to
achieve this level.
2.4 Examples:
When full heat is needed (during very cold weather, or on initial warm-up), the gas burner operates
at full output and the fan runs at maximum speed until the room temperature, determined by the
OpenTherm controller setting is reached.
The gas burner will then modulate down with the fan running at a reduced speed.
3.
TO LIGHT YOUR HEATER
3.1
Ensure that the gas supply to the heater is turned on.
3.2
Set clock to “OFF” position
3.3
Turn the OpenTherm controller (room temperature control) to position “30” (see Figure 1).
3.4
Switch on the electrical supply to the heater.
3.5
Set the “AIR HEATER” switch on the time control to “CONT” After a period of 15-20 seconds, the burner
will ignite automatically, indicated by the light on the indicator panel (see Figure 2). Shortly afterwards
the air circulation fan will start.
3.6
Adjust the Room Control to the desired setting (see Section 5).
3.7
The heater will now operate automatically under thermostatic control.
3.8
If the burner does not ignite the first time, the unit will make 4 further attempts. If it does not light, it will
lock out on E1. To reset the heater press the bottom marked “RESET”.
3.9
If, after carrying out the above instructions several times, flame is not detected, contact your local
service engineer.
4.
TO STOP YOUR HEATER
4.1
For short periods, e.g. weekends:
Turn the time control switch to the “OFF” position, or turn the room control anti-clockwise to its minimum
setting. This will cause the burner to extinguish and the heater fan to stop once the heat exchanger
has cooled. When you require the heating on again, turn to room control switch to the “ON” position,
or reset the room control to the desired setting.
4.2
For longer periods, e.g. a week or summer shutdown:
Turn the room control switch to the “OFF” position, set the room control to its minimum setting, then
turn off the electricity supply to the heater.
WARNING: Do not turn off the electrical supply when the main burner is lit, as this
may cause damage to the heater.
4.3 IMPORTANT:
If Summer Air Circulation is required, the electrical supply to the heater must remain
on.
