Installation Instructions

MAINTENANCE AND SERVICE

Turn off the electrical power supply and close the manual gas shutoff valve

and the manual water control valve before servicing.

• Be sure that all openings for combustion and ventilation air are not blocked.

• The venting system should be checked annually for any leaks, corrosion, blockages or damage.

• The burner should be checked annually for dust, lint, grease or dirt.

• Keep the area around the micro boiler clear. Remove any combustible materials, gasoline or any

ammable vapors and liquids.

• In accordance with all local codes and common safety practices, water discharged from the pres-

sure relief valve can cause severe burns instantly from scalding. DO NOT touch the pressure relief

valve.

• If the relief valve discharges periodically, it may be due to thermal expansion in a closed water

supply system. Contact the water supplier or local plumbing inspector on how to correct this situa-

tion.

• Visual check of burner ames (see below) through the burner window in the burner assembly lo-

cated at the middle of the micro boiler.

The manufacturer recommends having the unit checked once a year or as necessary by a licensed

technician. If repairs are needed, any repairs should be done by a licensed technician.
