Genie USER'S OPERATING INSTRUCTIONS
FOR YOUR SAFETY - READ BEFORE OPERATING
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A FIRE OR EXPLOSION
MAY RESULT, CAUSING PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE.
This appliance is equipped with an ignition device
which automatically lights the burner.
BEFORE OPERATING after a prolonged time off,
smell all around the appliance area for gas. Be
sure to smell next to the floor because some gas
is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
* Do not try to light any appliance
* Do not touch any electric switch
* Do not use any phone in your building.
* Immediately call your gas supplier
from a neighbour's phone. Follow the
gas supplier's instructions.
* If you cannot reach your gas supplier,
call the fire service.
* Isolate the appliance with the Service
Cock inside. If this is not accessible,
isolate at the gas meter.
* Do not use this appliance if any part
has been under water. Immediately
call a qualified service engineer to
inspect the appliance and to replace
any part of the control system and any
gas control which has been damaged.
CAUTION: Propane gas is heavier than air and
will settle on the ground. Since it can accumulate
in confined areas, extra care should be exercised
when lighting Propane heaters.
WARNING: There are no user servicable items in
this appliance. Do not interfer with any sealed
components.
MPORTANT INFORMATION
Incorrect water balance will cause premature
failure of this heater. Such damage is not covered
under warranty. For additional information please

Water Pressure Switch
A water pressure switch is provided in the heater to
shut off the burners in the event that water supply to
the heater is interrupted. The water pressure switch
should be checked and adjusted for proper opera-
tion by a qualified service person at the time of
installation, and thereafter checked at each service.
WARNING: Operation of the heater without water
circulation will cause rapid and severe damage to
the Heater.
Water Temperature Settings
The Heater is designed to provide the maximum
amount of heat to the pool up to one degree below
the set temperature. For that last degree it reduces
the power to maximise control. For certain installa-
tion designs, if the pool is used before it is up to set
temperature, the water entering the pool from the
Heater could be noticeably warmer than the pool.
This is not a fault but part of the design. It will reduce
for the final degree up to set temperature.
CAUTION
Elevated water temperature can be hazardous, and
the U.S. Consumer Product Safety Commission
recommends the following guidelines:
1. Spa or hot tub water temperatures should
never exceed 40°C (104°F). A temperature of
38°C (100°F) is considered safe for a healthy
adult. Special caution is suggested for young
children.
2. Drinking of alcoholic beverages before or during
spa or hot tub use can cause drowsiness which
could lead to unconsciousness and
subsequently result in drowning.
3. Pregnant Women Beware! Soaking in water
over 39°C (102°F) can cause fetal damage
during the first three months of pregnancy
resulting in the birth of a brain-damaged or
deformed child. Pregnant women should stick
to the 38°C (100°F) maximum rule.
4. Before entering the spa or hot tub, users should
check the water temperature with an accurate
thermometer; spa or hot tub thermostats may err
in regulating water temperatures by as much as
2°C (4°F).
5. Persons with a medical history of heart di-
sease, circulatory problems, diabetes, or blood
pressure problems should obtain a doctor’s
advice before using pools or hot tubs.
6. Persons taking medications which induce
drowsiness, such as tranquilizers,
antihistamines, or anticoagulant, should not use
spas or hot tubs.
Chemistry
Please see page 3 for the maximum levels and the
procedural requirements for adding chemicals
Cleaning
It is recommended that periodically the casing is
cleaned and sprayed with WD40 or similar liquid, and
any exposed threads are lightly coated in grease.
Service & Maintenance
It is recommended that the Heater is serviced every
2000 hours of operation, for normal use this is about
12 months. The control will alert when you when it
reaches this period by its display, ‘SEr’ alternating
with the temperature.
It is a mandatory requirement that any gas work
carried out must be by a Registered engineer with
an appropriate accreditation.
Winterisation
As supplied the Heater includes a dose of inhibitor
and anti-freeze, sufficient to protect the primary heat
exchanger down to -10° C. If the Pool and Heater
are not going to be used for the cold winter months it
is recommended that the equipment is winterised.
Contact your pool installer for help with this.
Failure to winterise the Heater during a period of
freezing could cause damage to the Heater which
will not be covered by your warranty.

IMPORTANT.It is important that no external
control devices are directly connected to this appli-
ance - unless covered by these ‘Installation and
Servicing Instructions’ or otherwise recommended
by the manufacturer. If in doubt, please enquire.
Any direct connection of a control device not
recommended by the manufacturer could infringe
the Gas Safety (Installation & Use) Regulations, the
above regulations and the normal appliance war-
ranty.
Manufacturer’s notes must NOT be taken, in any
way, as overriding statutory obligations.
Location of Heater
The Heater MUST be installed on a flat and level
floor, capable of adequately supporting the weight of
the Heater and any ancillary equipment.
Provision is provided for the heater to be fixed to the
floor.
It is IP 44 Rated and can be installed out of doors in
a suitable position. In all cases the choice of position
should take into account the flue, the plume and the
condensate drainage.
IMPORTANT NOTICE.
If the Heater is to be fitted in a timber framed build-
ing it should be fitted in accordance with the British
Gas publication ‘Guide for Gas Installations in
Timber Frame Housing’, reference DM2. If in doubt,
advice must be sought from the Local Gas Region of
British Gas.
The Heater may be installed in any room or internal
space. Particular attention is drawn to the require-
ments of the current I.E.E Wiring regulations and, in
Scotland, the electrical provisions of the Building
Regulations applicable to Scotland with respect to
the installation of the boiler in a room or internal
space containing a bath or shower.
Where a room sealed appliance is installed in a
room containing a bath or shower then the appliance
and any electrical switch or appliance control,
utilising mains electricity should be so situated that it
Condensing Pool Heater 312/08/09
INTRODUCTION
These Instructions cover a range of indirect, floor
mounted, gas fired, condensing pool heaters which
are room sealed and fan assisted. The flue system
available is concentric, left, right, rear, and vertical,
all up to 20 metres ‘FEL’. There is also an Outdoor
Top terminal for use where the Heater is installed
out of doors. The ignition system is fully automatic.
There are two models with different outputs - see
the Technical Data on Inside Cover for details.
Both can be installed in multiples to obtain a larger,
combined output.
The casing is of green and black polyester powder
coated mild steel. The Heaters use a high perform-
ance stainless steel heat exchanger and are suit-
able for connection to pools using chlorinated and
salt chorinated water provided the following levels of
chemicals are maintained.
pH 7.2 to 7.8
Total Alkalinity 80 to 140 ppm
Calcium Hardness 200 to 400 ppm
Salt maximum 30000 ppm
Free Chlorine 1 to 4 ppm
All chemicals must be introduced and completely
diluted into the pool water before being circulated
through the heater. Do not place chlorine tablets or
bromine sticks in the skimmer, high chemical
concentrations will result when the pump is not
running.
Chlorinators must feed downstream of the heater
and have an anti-siphoning device to prevent
chemical back-up into the heater when the pump is
shut off.
NOTE: High chemical concentrates from feeders
and chlorinators that are out of adjustment will
cause corrosion to the heat exchanger in the
heaters. Such damage is not covered under the
warranty.
Gas Safety (Installation and Use)
Regulations, (as amended).
It is the law that all gas appliances are installed by a
competent person (e.g. a registered operative) in
accordance with the above Regulations. Failure to
install appliances correctly could lead to prosecu-
tion.
It is in your own interest, and that of safety, to
ensure that the law is complied with. The installation
of the Heater MUST also be in accordance with the
current I.E.E.. Wiring Regulations, the Local Build-
ing Regulations, Building Standards (Scotland), the
Bye Laws of the Local Water Undertaking, any
relevant requirements of the Local Authority, and
