CAUTION
NOTICE
• Should overheating occur or if the gas supply fails
to shut off, turn OFF the manual gas control valve
external to the appliance.
• Do not add cold make up water when the
appliance is hot. Thermal shock can potentially
cause cracks in the heat exchanger.
• Failure to comply with these instructions can
result in substantial property damage, serious
injury, or death.
Protection must be taken against excessive pressure!
TO PROTECT AGAINST EXCESSIVE PRESSURE:

relief valve is installed in the recommended
location for Combi models using the domes-
tic hot water function (DHW Side).
• Verify the 30 psi relief valve supplied is in-
stalled in the location provided (CH Side). In
installations where the CH pressure exceeds
30 psi, a 50 psi relief valve (not included) can
be installed in lieu of the 30 psi relief valve.
• To avoid injury, install the relief valves in com-
pliance with local code requirements.
Failure to comply with these instructions can
result in substantial property damage, seri-
ous injury, or death.
