Frequently asked questions

As per the instruction manual, the inlet gas connection for the blow heater has size ¼” G LH thread. As per our specifications, these blow heaters are designed to be directly connected to the gas cylinder and so are provided with the corresponding hose connection. Unfortunately, we don’t have a hose which has the required thread to a bayonet connection. 

We do not have a longer hose we can offer, only the ones they are supplied with. 

We do not have official noise data. They are designed for industrial settings, so noise was not a design factor, therefore they are relatively loud.

1. Screw hose onto back of heater. 
2. Place cylinder behind heater. Screw in POL to cylinder. 
3. Check for gas leaks. 
4. Plug in electrical cord. 
5. Press on/off switch – fan turns on, then gas comes through, then sparks – allow 60 seconds 

1. Screw hose onto back of heater. 
2. Place cylinder behind heater. Screw in connection into cylinder. 
3. Check for gas leaks. 
4. Plug in electrical cord. 
5. Press on/off switch – let fan run for 30 seconds.  
6. Open gas valve by holding in button closest to gas inlet (on the left). 
7. Press other button (on the right) as many times as it takes to ignite/spark, so that it lights up the heater. 
8. Release the gas valve button after 5 seconds of the flame burning – the presence of the flame now keeps the gas valve open. 

No. Each heater has a set gas input and there is only 1 flame. Get a smaller or larger heater size for smaller or larger flame. 

It is a temperature dial. It controls the thermal cut off switch for if the room temperature gets too high. Best to turn all the way up so it doesn’t cut the heater off prematurely.

The heaters sold with the POL fitting (the HF30 and HF50 models and older HF15 and HF20 models) require a 45kg cylinder as these have been tested and approved to the relevant standards using the 45kg cylinder. The newer models of HF15 and HF20 have type 27 connections and these should be used with a 4.5kg or 9kg cylinder with the new type 27 connection. (The reason the larger ones aren’t made for the smaller cylinders is they will only last a couple of hours on them, and possibly freeze due to the high gas flow required). 

No, it doesn’t expire. The gas inside will stay pure until it is used up. The gas cylinder cannot be refilled though.

The cylinders are pin activated, so when the regulator is removed, the gas will not leak.
