ABOUT OUR MANUALS
Your Super Hot boiler has been provided with two manuals:
• User's Information Manual - This manual is intended for the owner or user of the boiler and provides
information on routine operation and maintenance, and emergency shutdown.
• Installation and Service Manual - This manual must only be used by a qualified heating installer,
service technician or gas supplier. Installation or service by anyone unqualified to do so may
result in severe personal injury, death or substantial property damage.
Both manuals should be kept in the envelope provided and affixed adjacent to the boiler so that they are
readily available for future reference.
Lighting Instructions Section 1
This boiler is always equipped with an ignition device which automatically and directly lights the main
burners (there is no pilot burner).
There are two possible ignition systems:
1. direct spark ignition with combination gas valve (equipped with gas control knob) and module.
2. hot surface ignition with combination gas valve (equipped with gas control knob) and module.
The lighting instructions shown in this section apply to both ignition systems. In addition, the lighting
instructions have been printed on a label attached to the boiler. If you are unsure which type of gas valve
or ignition system your boiler is equipped with, check the wiring diagram sticker on the boiler or contact
the factory.
WARNING
Should boiler overheat, or the gas supply fail to shut off, do not turn off or disconnect the
electrical supply to the circulating pump. Instead, shut off the gas supply at a location external
to the boiler.
