6 Servicing
6.1 Introduction
6.1.1 Servicing must be carried out by a properly
qualified person.
Whilst giving the following instructions for the care of the
Andrews Water Heater, the water heater is a gas appliance and
as such should be serviced annually by either Andrews Water
Heaters service team or a competent trained service engineer.
Water heaters are heat producing appliances. To avoid damage
or injury there must be no materials stored against the water
heater or vent-air intake system, and proper care must be taken
to avoid unnecessary contact (especially by children) with the
water heater and vent-air intake system. UNDER NO
CIRCUMSTANCES MUST FLAMMABLE MATERIALS, SUCH
AS GASOLINE OR PAINT THINNER BE USED OR STORED IN
THE VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE
SYSTEM OR IN ANY LOCATION FROM WHICH FUMES
COULD REACH THE WATER HEATER OR VENT-AIR INTAKE
SYSTEM.
Important
The water heater should be inspected at a minimum
annually by a qualified service technician for damaged
components and/or joints not sealed. DO NOT operate
this water heater if any part is found damaged or if any
joint is found not sealed.
The following maintenance should be performed by a
qualified service technician at the minimum periodic
intervals suggested below. In some installations, the
maintenance interval may be more frequent depending on
the amount of use and the operating conditions of the
water heater. Regular inspection and maintenance of the
water heater and vent-air intake system will help to insure
safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be
restricted. Clear the combustion air openings of any dirt, dust, or
other restrictions.
3. At all times keep the water heater area clear and free from
combustible materials, gasoline and other flammable vapors and
liquids.
4. Annually conduct a visual check of the main and pilot burner
flames to determine that they are burning properly. See the
Burner Flame Check section for illustration. If sooting or other
burner anomalies are evident, shut down the water heater by
turning off the gas per the instructions listed in this manual or as
listed on the water heater.
Warning
The ventilation air system may be HOT.
