a) Place the apparatus on an approx. 30-40 cm high pedestal to prevent the CO
2
, which sinks
to the floor, from extinguishing the flame.
b) Open a means of ventilation near the apparatus to allow sufficient oxygen to reach the pilot
flame.
What if the gas consumption is too high?
The following energy-saving hints are worth remembering:
a) Please inform yourself about the minimum temperatures for your plants to survive through
winter. Do not set the thermostat higher than necessary. Each additional degree means
unnecessary gas consumption. Heating is expensive if the external skin of your greenhouse
is made of normal glass, due to the high thermal conductivity. A glass house should be
insulated with air cushion foil. This, as a rule, reduces energy costs by up to 30 %.
b) Energy costs may be further reduced by turning off the pilot flame during the day.
What if the apparatus leaks?
The greenhouse heater types Frosty 2500 / Frosty 4500 are safe, tested and certified not only
under European CE directives but also DIN DVGW
[German Technical and Scientific Association for
Gas and Water]
standards. We have noticed, however, in our > 30 years of experience with gas
equipment, that customers make the same handling mistakes time and again. When
exchanging cylinders, the operator often does not check for cylinder – pressure regulator gas
tightness. Leak detection spray or soap water should be used to check for gas leakage after
every cylinder exchange. The slightest bubble formation indicates a leaky connection.
8. Tips for reliable operation
When taking the apparatus out of operation in summer, always store it in a bag, carton or
similar, to protect it from spiders and insects. These tiny creatures are attracted by the aromatic
substances in the gas and often block the gas passages with the dirt they bring in. The heater
then stops working and must be cleaned by a specialised gas company, at a cost.
9. Cleaning, repairs and disposal
•
Do not use abrasive or caustic or cleaning agents.
•
Before cleaning, switch off the apparatus and allow it to cool down for about 30 min. before
starting to clean.
•
Clean the enclosure with a damp (not wet) cloth, vacuum cleaner or feather duster.
•
Never submerge the apparatus in water.
•
Take the devices to be disposed of only to a suitable waste disposal point.
•
The apparatus may only be repaired by authorised specialists. Please therefore contact the
manufacturer or distributor in this regard.
•
Attention! The guarantee shall be null and void in cases of improper repairs.
•
Incorrect repairs may pose a hazard to the user and to others.
•
In a greenhouse, position the apparatus where good air circulation is ensured.
•
We recommend installation approx. 20-30 cm above the floor.
•
This apparatus is not suited for orchid and succulent rearing, since some orchids and
succulents cannot tolerate CO
2
enrichment. If you are not sure whether your greenhouse
plants can handle CO
2
enrichment, ask a gardener.
•
Attention! The enclosure heats up when in operation! Allow to cool down before
transporting.
•
Attention! Close the cylinder valve immediately in case of uncontrolled gas leakage.
4. Assembly and connection of the heater to the gas cylinder
Depending on application, screw the two supplied brackets to the bottom (upright heater, see
Fig. 1a) or to the back (wall heater, see Fig. 1b) before connecting the apparatus. The distance
between mounting holes is 328 mm for the Frosty 4500 wall heater and 228 mm for Frosty
2500.

Before connecting the apparatus, check that the local supply (gas type and gas
pressure) matches the settings of the apparatus. The specified values for the apparatus
are shown on its nameplate. This apparatus is not connected to a waste gas draw off. It
must be set up and connected according to the locally applicable installation
requirements. Especially ensure suitable ventilation.
