60 kW Pool Heater Installation and User Manual
WARNING:
Overheating/over-pressurising the burner or failing to follow installation instructions will
VOID THE WARRANTY. Please use a pool professional for your installation and ensure
they are given these instructions. Damage can be caused by failure to start the pump before
lighting the fire, by pump failure, mismanagement of valves or incorrect installation. It is the
owner’s responsibility to ensure adequate water flow at all times when the heater is burning.
Pool vacuuming or back-washing must not be carried out whilst the heater is lit. The feeds
from the skimmer and sump must be open and unrestricted as must the returns to the pool.
Pressure must never exceed 0.5 bar. Please check your household insurance for adequate
cover against accidental damage.
No return valve may be fitted on the outlet of the heater. This can result in accidental over-
pressure and failure of internal welds. A one-way valve is recommended in place of the valve
on the return leg (just visible in picture, bottom right). Chlorine levels must be kept to normal
ie 1-3 ppm and never in excess of 5ppm whilst burner is connected.
If the burner is lit with no water flow it will MELT!
Installing
The burner comes with standard 1 ½ inch female threads. Unit must be plumbed in 1 ½ pipe.
Do not reduce to any smaller diameters. The inlet must be at the bottom and outlet at the top.
You will need a male socket union for each of these, some pipe, 2 x Tee pieces and 2 valves.
You will need lots of PTFE tape on the threads to make a seal (more than usual). The small
rubber bung is the drain off and is fitted at the bottom rear of the unit.
The burner must be installed after the sand filter and should be the LAST item in any
plumbing system before the returns to pool as the pressure upstream can rise to over one bar
when the sand becomes clogged. Normal downstream pressure is about 0.2 bar. The burner is
pressure-tested in the factory to 0.5 bar. Install the pressure gauge supplied in the top of the
unit and on first use, open the flow valve gradually whilst monitoring pressure. If pressure is
high switch off and check your outlets for restrictions or consult your pool installer.
Commissioning
Air purge. On first switch on there will be large volume of air gurgling into the pool as the
water flowing in to the burner replaces the air. This is normal but should only last 2-3
minutes.
Condensation
Do not panic as it does look as though there is a leak! There will also be some fine ash from
the chimney on the first burn, it is obvious as it is the same curved shape as the inside of the
pipe. Do not be alarmed.
Hard water areas: If you are in a hard water area you may find some calcium deposits forming
and collecting in the bottom of the burner as the lime comes out of solution from your tap
water. Sometimes this can affect the water clarity until it has all been collected in your filter
and backwashed away. You may also need to disconnect the heater and flush it out with a
hose to remove scale deposits.
