INSTALLATION
The heater is connected to a hot tub using a
connection kit (included in complete hot tub
packages).
The kit is not supplied with the purchase of
only the heater but can be ordered separately.
Install according to instructions below if the
connection pipe is of SpaDealers
manufacture.
The heater is placed on a surface made from
wood, brick or cement. Let it stand a little
higher at the rear to prevent air pocket
formation that can disrupt the circulation and
cause damage to the heater.
1. For the upper connection pipe
(outlet), drill a 60mm hole in the side
of the hot tub, approx. 6 cm higher than the upper outlet of the heater. In the bottom of the opposite side
of the hot tub, make a similar hole for the inlet water to the heater. (NOTE: For an assembled hot tub kit this
step and step 2 are already made)
2. The skewed bushing is then screwed into the side. The curved bushing is screwed into the bottom.
3. The rubber pipes are attached between the heater and pipes from the hot tub. If the tubes are lubricated
(for instance, cooking oil), it is easier to assemble. Fasten with the included clamps.
4. In order to obtain good water circulation, the top pipe should slope upwards approx. 15°.
WINTER USAGE
If there is a risk of freezing damage then the heater must be drained of water after use. Self-circulation will cease
when the wood has burnt out and the small amount of water remaining in the heater can easily freeze and cause
damage to the heater. If electricity is available then a freezing guard can be installed in the heaters firebox to avoid
freezing damages when it is not in use. Upper and lower connection pipes must then be insulated.
Function
The heater functions as a conventional wood heater. The firebox is cm long and 3 cm in diameter. Maximum effect is
achieved by using dry wood (less than 15% moisture), 40-53 cm long and split into smaller parts. A load burns for
approx. 20-30 minutes.
Never use wet wood as it reduces the effectiveness considerably and may cause heavy deposits on the heater's heat
transfer surface. Also avoid alder wood. Controlling the draft and heating effect is done by regulating the lower draft
door. For fast heating, open about 10cm and keep it closed to maintain temperature once the water is hot.
