INSTALLATION INSTRUCTIONS
To register your product, visit gdaheat.com/register
1. Route the electrical supply wire from the circuit breaker to the wall thermostat. At the wall can of
heater #1, attach two sets of electrical supply wires with two cable clamp connectors (not included),
leaving a minimum of 6 inches wire lead. One set of electrical supply wire goes to the wall thermostat
and the other set goes to heater #2 (See Figure 7).
2. There are two supply ground wires in the wall can of heater #1. You’ll need to add a small piece of
copper wire (not included) to make the 3-wire connection with the ground screw (See Figure 7).
3. For heater #1, connect each heater wire to one of the supply wires going to the thermostat, and
to one of the supply wires going to the heater #2. Both wires from heater #1 must have a 3-wire
connection.
MULTIPLE HEATERS WITH ONE THERMOSTAT (MODEL CS ONLY)
4. For heater #2, make the connections in the wall can as shown in Figure 7 above. Proceed with STEP
4 Wire connections, number 2 on page 5.
5. Turn power back on at the main disconnect panel.
6. Proceed to OPERATING INSTRUCTIONS.
Figure 7
More than one heater can be wired in parallel on the same circuit breaker (be sure to check national and
local codes for safety requirements). Additional electrical supply wire and cable clamp connectors are
required, and you’ll need to use a wall thermostat. When wiring multiple heaters to one thermostat, the
heaters must be in the same room and be spaced a minimum of three feet apart.
The maximum amperage load you can put on one circuit breaker is limited to either 80% of the circuit
breaker capacity, or the maximum amperage rating of the thermostat, whichever is lower.
