ELECTRICAL SHOCK HAZARD —
For your safety, turn off electrical power
supply at service entrance panel before
making any electrical connections 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
wiring 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 – latest edition, and/
or the Canadian Electrical Code Part I, CSA
C22.1, Electrical Code.
The boiler when installed, must be electrically
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.

boiler wiring
Connecting terminals
All fi eld wiring is made through the eight (8) colored connectors
(shipped loose with boiler) directly to the control module. Line
voltage, 120 VAC, terminals are on the top of the control module.
Low voltage, 24 VAC, terminals are on the bottom of the control
module.
Wire entrances
Wire entrance knockouts are provided on the top left, the bottom
left side and the top right side of the boiler cabinet:
1. Line voltage— fi ve (5) knockouts on the top left of the cabinet
(Line In, Output 1, 2, 3, Boiler Circ.).
2. Low voltage— two (2) knockouts on the bottom left side of
the cabinet.
3. Multiple boiler communication wiring—a single knockout
on the top right of the cabinet.
Installer MUST use a strain relief through jacket
knockouts. Failure to do so can cause severe
personal injury, death or substantial property
damage.
Installer MUST SEAL all electrical entrances using a
sealed strain relief or a strain relief sealed with duct
seal putty or silicone. Sealing the entrances prevents
the boiler from drawing air from inside the boiler
room. This is particularly important if the boiler is
located in the same room as other gas appliances.
Failure to seal entrances could result in sever personal
injury, death or substantial property damage.
Wire routing in the cabinet
Line voltage:
(120VAC in, circulator outputs)
1. Install four (4) of the wire tie bases to the holes on the
left side interior of the cabinet.
2. Line voltage should be wired from the top left electrical
entrances following the left side of the cabinet.
3. Wires should be bundled together and secure with the
provided wire ties to the wire tie bases located on the left
side wire chase. Two (2) sets of bases are provided, one
(1)for line in and one (1) for the circulator outputs. Route
wires in front of the transformer then into terminal blocks.
4. Strip end of wire no more than 1/8" to avoid exposing
uninsulated wire.
5. It is recommended to install an On/Off service switch in
a junction box mounted near the boiler. Installation must
meet all National and local electrical codes.
Low voltage:
1. Mount low voltage wire grommet to desired low voltage
knockout.
2. Thermostat, aquastat, limit devices, system sensors,
0-10VDC input and outdoor temperature sensor wire
pairs should be routed through the grommet.
3. Wires should be connected directly into the corresponding
terminal block.
4. Low water cutoff should be routed following the
instructions in step 3. Provide strain relief and a seal at
cabinet entry.
5. Bundle all wires together with provided wire ties.
6. After wires are attached to the control terminal blocks,
make sure wires are properly sealed in the cabinet
electrical entrances.
