INSTRUCTIONS MANUAL FURNACES H1 - H2 - H4
The cupper pipes in the outer part of the furnace are connected by T joints and “elbows” followed by a
special hose for gas that is connected to the gas container. The plastic hose is equipped with a control
valve to avoid the flame return.
The burners can be used independently: In case of using only one of them it is advisable to use the one
on the left.
3. Safe use of the furnace.
The furnace is equipped with several safety devices:
- Pressure reducer device in the point of connection between the gas container and the supply
line.
- Control valve to prevent the flame return by the supply line.
- One valve connected to the Thermo couple to close tha gas supply in case of accidental
opening of the valves or in case the burners has stopped due to any ignition problem.
The frontal part of the furnace has been made of a metal sheet that works as a protection
screen. The entrance of the furnace must be closed while it is not being used.
In order to use the furnace, the users must compulsorily wear a personal protection kit
including:
- Safety shoes.
- Prtotection gloves.
- Safety wear.
- Saftey googles.
4. How to start up and use the furnace.
- Once the supply hose is connected, open the gas container regulator “click-on.”
- Turn one of the path keys of one of the burners.
- Keep the blue button of the safety key pressed for the gas to come out by the burner.
- Either insert a match in the inner ceramic chamber of the furnace, being careful with the
starting ignition because it causes an instant deflagration due to the gas cummulation in the
inner part of the furnace or then keep on pressing the blue button of the safety valve for half a
minute until it the burner keeps lit when you release it.
- If the burner stops when you release it, it is because the thermo couple at the middle of the
furnace chamber has not reached the proper temperature to keep the gas path and it
automatically closes the burner by activating its safetu function. If it occurs you should insert
the tip of the thermo couple a bit more inside the chamber without getting to have direct contact
with the flame avoiding it from having an excess of temperature and get damaged.
- Once we have one of the burners performing , we could open the path keys of the other
burners in order to inflame them in case we need it.
- With the blue regulator we can graduate the power of thr burners.
- In order to stop the burner, just close the path key of it and then close the “click-on” of the
propane gas container.
- Afterwards remove the gas container regulator as a precaution.
The blue regulator that the furnace has must not be removed because it will cause the
malfunctioning of it.
