Choose conductor size according above tables and your local regulations.
IMPORTANT
Gas units are voltage specific. Supply voltage must match voltage rated on data plate.
■ Gas units are supplied with grounded power cord and plug.
■ Electric units are NOT supplied with power cord.
To connect power supply for electric units, models 6, 10:
■ Open the operator panel. (Fig. 8)
■ Insert power cord through cable inlet under left side of unit to desired
length and secure the cable connection tight. (Fig. 9)
■ The circuit diagram is located behind the control panel.
To connect power supply for electric units, models 1020, 20, 40:
■ Access power connection terminals by removing left side panel.
■ Insert power supply cable through cable inlet under left side of unit to desired
length and secure the cable connection tight. (Fig. 9)
■ Connect supply wires as follows:
Gray terminals: L1, L2, L3, phase sequence
does not need to be observed
Blue terminal: Neutral (if applicable)
Yellow/Green terminal: Ground
IMPORTANT
In some areas Henny Penny Electric Combis are shipped set up for 240 volts, but
can be converted to 208 volt operation. If conversion is necessary the unit must be
reset and calibrated.
Convert from 240 volt to 208 volt operation
■ Disconnect unit from power supply source.
■ Open service door (Fig. 8) by loosening fastener at top of the unit over the
control panel using a 5 mm Allen wrench. A rubber grommet must first be
removed to access the bolt.
■ Move transformer primary lead from the 240v tap to the 208v tap (Fig. 10).
■ Open left side panel and locate relay K3.1 (Fig. 11).
■ Remove the jumper wire from the appropriate terminal positions. The
terminals on K3.1 relay socket are numbered. Use the chart below to
determine from which terminals to disconnect jumpers.
