2. 

Lift and remove front cover. Remove screws (2) from 

cover on junction box located on boiler's left side. Remove 

junction box cover.

3. 

Guide controller or thermostat wire through round 

grommet(s) located in the junction box on boiler's left 

side.

4. 

Tilt control box forward by opening holding clip located on 

left side of control housing.

5. 

Expose M1 and M2 terminal blocks by removing screw 

from plastic cover on left. See Figure 8-3.

6. 

Remove plastic from channel in plastic cover.  Run wires 

through new opening. 

7. 

Connect wires to appropriate terminals on connection 

block. 

8. 

Tilt control box back to original position.  Ensure clip on 

left side of control box is fully engaged.

9. 

Replace front cover and cover to junction box.

10. 

Turn power to boiler on.

Dry contact end switches from various manufacturers can be 

attached to boiler control PCB.

8.5 Main Supply Connection

Main supply is connected to terminal block M1 which is high 

voltage (120V / 60Hz).
Fuses, 3.15 A, are incorporated in the power supply terminal 

block. To check or replace fuse pull out black fuse carrier.

TERMINAL BLOCK M1

(L) = Live (brown)
(N) = Neutral (light blue).

= Ground (yellow-green).

(1) (2) = contact for 120V Room Thermostat.
Place jumper back on terminals 1-2 of boiler terminal block 

M1 if room thermostat is not used or if Remote Control is 

not installed.

Fuse Holders (2)

DANGER

Electrocution Hazard! HIGH VOLTAGE - Connections 

in terminal block M1 are high voltage (120V / 60Hz). 

Before making connections, verify appliance is 

disconnected from power supply. Respect the input 

polarity on terminal block M1: L (LINE) - N (NEUTRAL). 

Failure to follow these instructions WILL result in death 

or serious injury.
