such locations cannot be avoided, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance. The pan
must not restrict combustion air flow.
The flow of combustion and ventilation air shall not
be obstructed.
This appliance is not suitable for use in an

preventer in the cold water supply line, means shall
be provided to control thermal expansion. Contact
the water supplier or local plumbing inspector on
how to control this situation.
Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the
appliance.
