WARNING
1. Warning Information:
FOR SAFE AND EFFICIENT OPERATION THIS APPLIANCE NEEDS A FREE SUPPLY OF
FRESH AIR.
IN THE ABSENCE OF SUFFICIENT OXYGEN CARBON MONOXIDE (C0) WILL BE
PRODUCED.
CARBON MONOXIDE EVEN IN SMALL CONCENTRATIONS CAN CAUSE DEATH
IN ADDITION CONCENTRATION OF CARBON DIOXIDE (CO2) MUST BE LIMITED TO SAFE
LEVELS.
ADEQUATE VENTILATION MUST THEREFORE BE PROVIDED AT ALL TIMES, THIS CAN
BE ACHIEVED BY HAVING 2 OPENINGS, ONE ABOVE AND BELOW THE HEATERS OF AT
LEAST:-
512 Square Centimetres (80 square inches) EACH - PER
SRB38 HEATER.
BS: 6896:1991. - Installation of Gas Fired Overhead
Radiant Heaters refers:-
Clause 7.3.1. 7.3.2. and 7.3.3.
The total installation shall be designed, installed and operated such that the concentration of
carbon dioxide at positions where person may be present shall not exceed 2,800 p.p.m.
To provide for the above using natural ventilation, high and low level ventilation shall be
provided by permanent openings of 46 CM2/KW total heat input. The lower level inlet shall be
below the appliance(s) and the high level outlet shall be above the appliance(s). The vertical
distance between the centre line of the high and low level grilles shall not be less than 3M. The
required air flow rate using mechanical ventilation shall be 33 M3/h per kW of total rated heat
input.
N.B. INSPECT ALL OPENINGS REGULARLY AND CLEAR IF NECESSARY, AS LITTER,
DUST, FEATHERS AND OTHER MATTER MAY BLOCK THEM.

2.2 VENTILATION
It is IMPORTANT that correct ventilation at all times is provided in poultry houses heated
by Space-Ray brooders.
The temptation particularly during the winter months to close up the poultry houses to
conserve heat and save money must be resisted, even during the heating up period prior
to the arrival of the stock.
The WARNING notice on the facing page contains details of the correct size and position
of ventilation openings for the safe and efficient operation of this appliance. It also
contains details of the required air flow rate when using mechanical ventilation.
If you are in any doubt as to the required ventilation contact SPACE-RAY direct, by
telephone or fax.
