burners and circulating air passageways 
of the appliance be kept clean.

Shut off water inlet. 

Open hot water tap at nearest faucet. 

Close outlet valve on unit.

4 screws.

Use pressurized air to remove dust
from the main burner, heat exchanger
and fan blades. Do not use a wet cloth
or spray cleaners on the burner. Do 
not use volatile substances such as
benzene and thinners. They may ignite
or fade the paint.

Use soft dry cloth to wipe cabinet.
