HAZARD INTENSITY LEVELS
1. DANGER: Failure to comply will result in
severe personal injury or death and/or
property damage.
2. WARNING: Failure to comply could result
in severe personal injury or death and/or
property damage.
3. CAUTION: Failure to comply could result
in minor personal injury and/or property
damage.

The electrical isolator should only be used in
an emergency and should not be used for
closing down the main burner, as it switches
off the fan prematurely and may damage the
heat exchanger, invalidating the warranty.

NFORMATION
The instructions in this manual apply to Model RHC
8000(M) RJL gas-fired/fan-assisted warm air heaters
suitable only for incorporation in air handlers built for
outdoor installation. This appliance must be installed in
accordance with the rules in force. Before installation,
check that the local distribution conditions, nature of
gas and pressure and adjustment of the appliance are
compatible.
A permanent electricity supply of 230 volts, 50 Hz,
single phase is required.
Model RHC 8000(M) RJL heaters are approved for
outdoor or rooftop application.
Category II
2H3+
These instructions are only valid for the countries
Great Britain (GB) and the Republic of Ireland (IE).
Check that the local distribution conditions of electricity
supply, type of gas and pressure of the appliance are
compatible.
When installed in Great Britain the total installation
must comply with the requirements and
recommendations of British Standard BS 6230
“Installation of Gas Fired Forced Convection Air
Heaters for Commercial and Industrial Space
Heating". The installation must also be in accordance
with the relevant requirements of “The Gas Safety
(Installation and Use Regulations) and “Amendment
regulations 1990” and “Electrical Regulations” (in GB
the IEE Regulations). The requirements of the “Local
Building Standards Office”, the premise “Insurance”
undertaking and the “Fire Office” must also be
observed. When the external control calls for heat, an
electronic control begins the ignition sequence to
provide for a safe start. Under normal conditions the
fan motor runs constantly and after a call for heat it
switches the heater on through a room or duct stat.
However, in some applications, about 30 seconds
after the call for heat, the fan control relay will activate
the fan motor of the air handler.
