Whenever the gas supply piping is pressure tested the
boiler/water heater gas controls must be protected.
If the test pressure is equal to, or less than
1/2 psig
,
3.5 kPa
isolate the boiler/water heater by closing it’s
manual shut off valve, see Figure 12. If the test pressure
is greater than, or equal to
1/2 psig
,
3.5 kPa
, disconnect
the boiler/water heater and its individual shut-off valve.
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 fi ls 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 for the boiler/
water heater. A 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.
Line voltage fi eld wiring of any controls or other devices
must conform to the temperature limitation of type T wire
at
95°F
,
35°C
above room temperature. Use copper
conductors with a minimum size of #14 awg.
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, tur n off the manual gas control valve to the
appliance. Do not interrupt water fl ow 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 fi ll 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
,
82.7kPa
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
,
82.7 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” section. 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.
