SpaDealers PRO24 Gas Water Heater
Product Information
The product is a gas heater that requires a pressure reducer of 30mbar and 2kg/h. A protective case for the gas heater is also available as an accessory that protects the heater from wind and rain. The front part of the protective case is detachable and there is fireproof material behind and on the sides of the heater. Above the heater, an inclined fireproof part leads exhaust fumes away. The product comes with a brass connector and seal to prevent gas leakage. The product should be checked regularly to ensure good air and to prevent the gas pipe from becoming cracked and leaking gas due to long-term use.
Product Usage Instructions
- When the gas is running out, turn the knobs for Gas and use a pressure reducer of 30mbar and 2kg/h.
- If draining the heater and there is a risk of freezing, loosen nuts D and pull the hoses out of the connection so that all water can run out.
- Use the supplied brass connector and seal to prevent gas leakage. Test the gas heater for leaks before use. If gas leakage occurs, refer to page 7 of the manual for simple advice to prevent a fire.
- If the stove is left outside in freezing temperatures, disconnect it and take it indoors where there is no risk of freezing.
- Regularly check the gas pipe for good air tightness. If cracked, replace the pipe immediately. The gas pipe should be checked at least once a year.
- Use the correct low-pressure regulator. The types of gas cylinders and connection methods of low-pressure reducers (30mbar, 2kg/h) can vary. Refer to the manual for examples of correct and incorrect types. NEVER use an adjustable controller.
- Note that the product requires 2kg/h of gas to give full power. With a flow of 1kg/h, the power is reduced by 60%.
GAS HEATER PRO24
FOR HEATING OF WATER IN HOT TUBS
Thank you for choosing a gas heater from SpaDealers. The heater is easy to
use. When connecting to a hot tub, there’s a connection kit (A) with pump
incl. hoses accessories (included in complete hot tub packages). It is
connected as shown below. For the heater to start it needs a water flow
created by a pump. Connect the upper connection to the heater and wait until
water starts seeping out in the lower black nut (1). That means the air has
been displaced and the pump can be started. Note * The pump must not be run
dry as this can cause damage to the rotor shaft. When the water starts flowing
the ignition mechanism is activated automatically. If gas is connected and
turned on the torch will ignite and start heating the water. The three white
knobs should all be adjusted to Max.
TIP! When the gas is running out you can turn the knobs for Gas and
When draining and there is a risk of freezing, loosen the nuts D and pull the hoses out of the connection so that all water can run out.
PROTECTIVE CASE FOR GAS HEATER
(item DTHHG)
As an accessory there is this handy protective case for the gas heater that
protects it from wind and rain. The front part is detachable and is removed
during use. There is fireproof material behind the heater and on the sides.
Above the heater an inclined fireproof part leads exhaust fumes away. We also
have the blue print for DIY’ers.
Use your gas heater properly and you will avoid unnecessary problems not
covered by the warranty. Here follows the most common problems that can be
effectively avoided with proper maintenance.
The most common problem that can occur is when contaminated water is used and
the filter before the pump clogs up. This stops the water flow. The stove will
then switch itself off. No temperature is displayed and there is no ignition
spark. The problem is corrected by cleaning the filter. If there is also a
strainer filter in the pipe “Water Inlet”, it can be removed as the outer
filter by itself is enough.
ATTENTION! If the pump sucks in air, the same thing happens and in both
cases there is a big risk that the pump will be destroyed as it does not get
sufficient “lubrication” from the water. If that happens the pump often starts
to make a “howling” noise and the warranty does not apply in such a scenario.
One problem that may occur and one that is serious in terms of safety, is a gas leakage. Use the supplied brass connector and seal. There are clear instructions on page 5 of the manual. Before the gas heater is taken into service, also test it for leaks. When gas leakage occurs, a fire results, but it can be prevented by following the simple advice given on page 7 of the manual.
In standard configuration the gas heater is not protected against rain and such if not placed under a roof. Water entering the heater leads to electrical failure and the material may start to rust. It’s easy to make a protective shelf that covers the stove. You must then take into account the installation regulations with dimensions on page 4 of the main manual. To reduce the minimum safe distance, a refractory material can used. On our website; www.spadealersuk.com, drawings can also be downloaded. The protective shelf is also available to order as an accessory
If the stove is left outside in freezing temperatures, then the heat exchanger could freeze and be destroyed. If the stove is not protected so that water cannot freeze in the heater, it shall be disconnected and taken indoors where the risk of freezing exists.
THE GAS PIPE MAY BECOME CRACKED AND LEAK GAS DUE TO LONG TIME USE.INSPECT IT REGULARLY.
(Fig. 6) Check the connections of the gas pipe regularly with soapy water (Fig. 6) to make sure there is no gas leakage. In case of gas leakage, never make fire or touch any electric-switches for the ventilation fan, etc. Do not connect or disconnect any power plugs; otherwise, a flame or spark could ignite the gas, causing a fire or explosion. Close the master gas valve, open all the doors and windows to exhaust the gas outside the house. Stop using the water heater and contact a service department or the gas supplier.
IN CASE OF GAS LEAKAGE, NEVER MAKE A FIRE OR TOUCH ANY ELECTRIC SWITCHES,
NOT MAKE TELEPHONE CALL IN THE ROOM, OPEN ALL DOORS AND WINDOWS
Regularly check the pipe to make sure of good air tightness. If cracked,
replace the pipe at once. Under normal conditions, the gas pipe needs to be
checked once a year.
USE THE RIGHT LOW-PRESSURE REDUCER
The types of gas cylinders and connection methods of low-pressure reducers
(30mbar, 2kg / h) can vary. It is important that the correct low-pressure
regulator is used. Here are examples of the correct type and also incorrect
types. NEVER USE an adjustable controller.
Examples of correct gas reducers and incorrect ones
Note that the amount of gas that the stove needs to give full power is 1.6 kg / h. With a flow of 1 kg / h, the power is 60% less. So the most optimal is 2 kg / h.
