MAINTENANCE

CAUTION

Using or storing chlorine based products on or
near the booster heater may shorten the life of

the unit and void the product warranty.

NOTE: Refer to the exploded views and parts list for
part identification and location.

NOTE: Refer to the wiring diagram for specific
electrical information.

GENERAL

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. (See Figures 9 and 10.) Depending on
the condition of the kitchen environment, the
burner and heat exchanger fins 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.

4. Once a month check and clean (if necessary) all

air inlet holes on the bottom of the unit and the
vent on the top of the unit.

5. The front cover should be removed and all

components visually inspected at least twice a
year. Check for evidence of chafing or heat
damage to any wiring or components. Check
also for any signs of water leakage at any of the
plumbing connections. If there are signs of any
damage or leakage contact the Hatco
Corporation or your authorized service agent.

6. The relief valve should be manually operated at

least once a year to ensure proper operation.

WARNING

Before performing this operation, care should
be taken that any of the discharged water does
not come into contact with the operator or
surrounding surfaces. The water can be
extremely hot and can cause severe scalding
and damage to the property.

If the relief valve discharges periodically, this
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 situation. Do not plug the relief

valve.
