ELECTRICAL WIRING

Electrical Power Connections
CAUTION:Label all wires prior to disconnection
when servicing controls. Wiring errors can cause
improper and dangerous operation! Verify proper
operation after servicing.
ATTENTION. Au moment de l'entretien des
commandes, étiquetez tous les fils avant de les
débrancher. Des erreurs de câblage peuvent
entraîner un fonctionnement inadéquat et
dangereux. S'assurer que l'appareil fonctionne
adéquatement une fois l'entretirn terminé.
The electrical connections to this boiler/water heater
must be made in accordance with all applicable local
codes and the latest revision of the National Electrical
Code, ANSI/NFPA-70. Installation should also conform
with CSA C22.1 Canadian Electrical Code Part I if
installed in Canada.
Install a separate 120 volt 15 amp circuit breaker for the
boiler/water heater and pump, see Table 11. A properly
rated shut-off switch should be located at the boiler/
water heater. The boiler/water heater must be grounded
in accordance with the authority having jurisdiction, or
if none, the latest revision of the National Electrical
Code, ANSI/NFPA-70.

*Use separate circuit breaker that is properly sized for
pump and pump contactor.
Line voltage field wiring of any controls or other devices
must use copper conductors with a minimum size of #14
awg. Use appropriate wiring materials for units installed
outdoors. The wire size must be compatible with the total
amp draw of the circuit.
Refer to the wiring diagram supplied with the boiler/
water heater for proper wiring connections.

GENERAL OPERATION

WARNING: Before proceeding read and fully
understand the instructions contained in this
manual. Do not attempt to operate this boiler/
water heater if it has not been installed in
accordance with the guidelines set forth in this
manual. Failure to comply with this warning can
result in extensive property damage, severe
personal injury or death!
Should overheating occur or the gas supply fail to shut
off, turn off the manual gas control valve to the
appliance. Do not interrupt water flow through the boiler/
water heater.
En cas de surchauffe ou si l'alimentation en gaz ne
s'arrête pas, fermez manuellement le robinet d'arrêt de
l'admission de gaz.
Hydronic Heating Boilers
Open the make-up water valve and slowly fill the boiler
and all of the radiation with water. Ensure that all bleed
and drain valves are closed.
Adjust the make-up water pressure regulator so a
minimum 12 psig, 83 kPa system pressure is
maintained at the highest point in the system piping. If
a make-up water pump is used adjust it to maintain a
minimum 12 psig, 83 kPa system pressure.
Open the system bleed and drain valves one at a time
to purge the air trapped in the heating system piping.
With the boiler off, run the system pump for at least 30
minutes and bleed the system piping using the bleed
valves. If strainers are used in the system piping the
make-up water valve should be closed and the strainers
checked and cleaned.
The system expansion tank should be checked to
ensure that the correct water level in the tank is
maintained. The tank should be less than half full of
water with the system full and adjusted to the correct
operating pressure.
Start the boiler as described in the "OPERATING
INSTRUCTIONS". Run the boiler for at least an hour.
The system pump(s) and all radiation units must be
operated during this time. Ensure that the make-up
water valve is open.
Shut the boiler off and open the bleed valves to purge
the air trapped in the heating system piping. Close the
make-up water valve and check and clean the strainers
and make-up water pressure reducing valve.
