WARNING
CAUTION
To Turn Off Gas To Appliance:
1. Turn off power switch on heater.
2. Turn off all electric power to the appliance if service is to be
performed.
3. Shut off external manual gas valve.
4. Remove front cover of heater for access to the control
compartment.
5. Turn gas control knob clockwise to OFF. Do not force.
6. Replace front access panel.
To avoid freezing water damage to the Booster Water
Heater when the outside temperature is below 32°F (0°C),
the unit must be left on and the venting must be protected
from migrating cold air.
1. Keep the area around the heater free and clear of debris
and flammable materials. Do not block air intakes or vents.
2. The recirculating water pump motor is permanently
lubricated and requires no other maintenance.
3. Visually observe and inspect the burner and pilot flame
every six months. When the burner is operating properly, a
clean blue flame will be visible. Depending on the condition
of the kitchen environment, the burner may need to be
cleaned of lint or grease-laden dust. If any problems are
apparent, discontinue use of the heater and contact the
Hatco Corporation or your authorized service agent.
Broad Blue Outer Flame
Light Blue Inner Cone
Slotted Burner Element
• The flame during full burn is a broad blue color. An inner
cone slightly lighter in color will also be visible.
• The flame should not be rising off of the face of
the burner element.
• Yellow tipped flames suggest a need for
adjustment or cleaning of the burner assembly.
4. Visually observe and inspect the heat exchanger and
exhaust blower fan. Depending on the condition of the
kitchen environment, the heat exchanger and fan may need
to be cleaned of lint or grease laden dust. If any problems
are apparent, discontinue use of the heater and contact the
Hatco Corporation or your authorized service agent.
5. Once a month, check and clean (if necessary) all air inlet
holes on the side or back of the unit.
