2.1 Safety warnings
The installation and maintenance of this air heater should be performed by an authorized
qualified competent installer in accordance with this manual, using calibrated equipment.
This heater must be installed in accordance with the manufacturer's instruction and local codes.
The qualified installer needs to follow the local health and safety codes.
This appliance may only be operated and serviced by sufficient instructed people. Failing to
follow the instructions can lead to damage to the appliance or the installation.
This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand
the hazards involved. Children shall not play with the appliance. Cleaning and user
maintenance shall not be made by children without supervision.
Always follow these safety instructions:
•Make sure that the area around the appliance is dry when working on the appliance.
•Always close the doors and inspection hatches unless adjusting and checking the heater.
Before working on an already installed heater:
- Set the thermostat to lowest setting.
- Close the main gas switch. The main gas switch should be situated upstream in the gas
line near the heater.
- Turn off all electric power to the appliance
After working on the heater always check for gas leaks.
Close the doors and hatches of the appliance.
2.2 Important checks before installation
2.2.1 Pre-check instructions
Before unpacking and installation, please check (i.e. on the data badge) if the heater is in
accordance with the order and if it is suitable for the local present provisions (gas type, gas
pressure, electrical supply etc.)
The heater has been tested in detail on safety and correct operating settings before leaving the
factory. It has been adjusted for the type of gas that is stated on the data badge. Should there
be any doubt, please contact your supplier.
2.2.2 Gas type
The unit is suited for OR Natural gas OR Propane gas. On the labels on the packaging and the
heater can the gas type that the heaters is set up for can be found. In case the heater needs to
be converted to another gas type contact your supplier. It can only be converted by the
manufacturer or its representative.
2.2.3 Standards
The Installation must comply with all applicable local and national standards.
The installation of the air heater must be in accordance with the relevant requirements of the
Gas Safety regulations (for example in GB; The Institute of Gas Engineers IGE UP-1 and 2),
building regulations and the IIE regulations also incorporating the gas safety (installation and
use) regulations. Other national and/or local regulations may apply (the Local Authority ,Fire
Officer and Insurers)

2.2.4 Protection from water and dust
The heater is not waterproof. This means that it may not be exposed to rain, spry or dripping
water. The IP classification is IP00B
The appliance is not designed for use in a very dusty environment. Dust may accumulate in the
heater and may cause a defect of the heater. This is also the case for the room-thermostat.
2.2.5 Protection against dust
The appliance is not designed for use in a very dusty environment. Dust may accumulate in the
heater and may cause a defect of the heater. This is also the case for the room-thermostat
2.2.6 Temperature
Do not install the heater in places where the temperature can rise above 35°C. At higher
temperatures the internal components will degrade much faster. This is not covered by the
guaranty.
2.2.7 Corrosive environment
The heater should not be installed in areas containing any corrosive or explosive vapours. It
should be prevented that chlorine or other corrosive containing vapours are sucked into the air
intake. These vapours will result in corrosion of the heat exchanger and a leakage of
condensate and flue gas. Defects caused by this are not covered by guaranty. Please consult
your supplier. This is also the case for the room-thermostat
2.2.8 Installation distances
Keep sufficient distance between the heater and any obstruction , in connection with safety and
access for service and maintenance. Pay particular attention to any flammable materials.
Please take into account the possibility to open the door of the heater for the necessary service
and maintenance work . Make sure the air flow to and from the heater is unhindered. Any
obstacles should be a minimum of 5 metres away from the front of the heater. Read the
chapter “Installation” carefully.
2.2.9 Condensate discharge
This is a condensing heater. This means a condensate water discharge system should be
installed according to local regulations. Never block this discharge.
2.2.10 Maintenance
For the safe and proper operation of the heater periodical maintenance is necessary. When the
heater is not serviced and cleaned in time, it could lead to damage of the heater or its
surroundings.
2.3 Guarantee
The guarantee becomes void when the air heaters are not installed and serviced in accordance
with this manual.

4.1 Positioning
•Check that the support is solid enough.
•The heater is designed as free hanging. The heater
should be able to blow the warm air free from any ducting
or obstacles. Also the air intake should be free.
•Keep sufficient distance between the heater and any
obstruction , in connection with safety and access for
service and maintenance. See the drawings in this
chapter. Pay particular attention to any flammable
materials. Please take into account the possibility to
open the door of the heater for the necessary service
and maintenance work . Make sure the air flow to and
from the heater is unhindered. Any obstacles should be
a minimum of 5 metres away from the front of the
heater.
•The heater can be installed horizontally or on an angle
of maximum 45 degrees downwards.
•When the heater is installed other than horizontal,
Always re-adjust the CO2 setting from the gas valve.
•The heaters type 10 and 20 are provided with 2 off
M10 threaded sockets as fixing points (see the
dimension diagram).
•The types 30 and 40 have in the middle a M10 socket and also 4 sockets on the top corners
of the heater
•The types 50 and 60 have on the top and bottom 4 M10 sockets. (see drawings)
•Use preferably the Winterwarm suspension kits.
•Make sure that after fitting, there is no mechanical tension on any connecting gas or electric
supplies.
•If the heater is installed with the air stream vertical downwards the maximum suspension
height is 8 meters. Otherwise the warm air will not reach the floor.
Attention:
See the application-restrictions in this manual (Chapter 2) for further installation restrictions.

4.2 Gas connection
The gas supply line has to meet the national valid requirements and possibly the local
requirements of the building inspector, police or fire brigade. (In GB it must comply with Gas
Engineers publication UP-1 and UP-2 together with BS 6891.
A manual isolation valve in the supply line must be placed within reach of the heater, and all gas
lines must be mounted without any mechanical tension.
When testing the supply lines with pressures above 60 mbar, this manual valve at the heater
must be closed.
The working and standing supply pressure must be a minimum of 17 mbar, and a maximum of
30 mbar ,measured at the inlet pressure nipple of the gas control in the heater
In case the heater needs to be converted to another gas type contact your supplier. It can only
be converted by the manufacturer or its representative.
4.3 Electrical connection
4.3.1 230Vac supply
The installation must comply with local and
national requirements, ( as well as IEE
regulations)
Never use a room thermostat to interrupt the
electrical supply to the heater!
Make provisions to completely isolate the heater for maintenance purposes. This can be an
isolation switch (min.3mm contact opening gap) , a power plug or a non-switched fuse spur.
The wiring diagram for the heater can be found towards the end this manual.
The supply is 230Vac. with earth. The control circuit is a two wire low voltage bus
communication.
