ELECTRICAL SHOCK HAZARD

 — For your 

safety, turn off electrical power supply at service 
entrance panel before making any electrical con-
nections to avoid possible electric shock hazard. 
Failure to do so can cause severe personal injury 
or death.

   The installation must comply with: National 

Electrical Code and any other national, state, 
provincial or local codes or regulations. In 
Canada, CSA C22.1 Canadian Electrical Code 
Part 1, and any local codes.                

   Wiring must be N.E.C. Class 1. If original wir-

ing as supplied with boiler must be replaced, 
use only type 105 °C wire or equivalent. Boiler 
must be electrically grounded as required by 
National Electrical Code ANSI/NFPA 70 – lat-
est edition

, and/or the Canadian Electrical Code 

Part I, CSA C22.1, Electrical Code.

  

The boiler when installed, must be electri-
cally bonded to ground in accordance with the 
requirements of the authority having jurisdiction 
or, in the absence of such requirements, with the 
National Electrical Code, ANSI/NFPA 70

 – latest 

edition

, and/or the Canadian Electrical Code 

Part I, CSA C22.1, Electrical Code.

Wire entrances

All field wiring is made through the bottom of the boiler  
through two (2) black grommets shown in Figure 61.

Connecting terminals

The electrical connections terminal block can be accessed 
after removing the front jacket panel. The layout of the ter-
minals for the various connections are shown in the wiring 
diagram in the following pages. 

Room thermostat 

When connecting a room thermostat, connect the  thermo-
stat across terminals 

R

 and 

W

 for a two (2) -wire thermostat 

or optional 

R

,

W

 and 

C

 for a three (3) -wire thermostat, see 

Figure 62, Item 72. The thermostat connector is located on 
the right side of the boiler. 

 

Either a voltage free thermostat or a 24VAC 
thermostat can be connected to the boiler.
