Note 2
Note 1: The distance used is rounded down to 18.5 (60).
Note 2: The actual smallest pipe size for the required capacity is ¾” from the table. However, the gas pipe size from
brooders 3 and 4 to the regulator must be 1” diameter and therefore a smaller diameter pipe cannot be used. If ¾” pipe
was used from the Tee to brooder 1, the pressure drop in the rest of the system would exceed the design pressure drop of
1.25mbar.

ELECTRICAL CONNECTIONS – No. 2 and No. 4 Control
1. All electrical wiring to this brooder must be installed in accordance with the latest or current
National Regulations and any Local Regulations, which apply.
2. The electrical system must be electrically grounded in accordance with the latest or current
National Regulations and any Local Regulations, which apply.
3. The brooders with the #9 control options do not require any electrical supply because they
generate their own electricity and operate thermostatically off this power. The brooders with
the #2 control option require a 24VAC supply to each brooder. This is provided via a 24Volt
Transformer. The 24Volt Transformer MUST be large enough to operate the number of
brooders connected to it (see table below). This is calculated as follows:
