Failure	Cause	Remedy
The ZON MARK 2, fully connected, fails to operate at all.	The valve of the gas tank is not open.	Open the value.
	The interval regulator is not opened.	Open it by turning into the + mark direction; if the detonations are too frequent, turn it a little to the - mark.
	The gas tank is empty or has too little pressure.	Connect a new gas tank.
	The gas valve, no. 7042, can't be opened. This is possible if the ZON MARK 2 has not been used for some time.	With two fingers, pull up the hinged clip, no. 7042M, two or three times.
Leaks.	The coupling nut gas regulator is not tight enough.	Tighten coupling nut with suitable spanner.
	The hose from the regulator-unit to the ZON MARK 2 has been damaged.	Renew the hose. A fast method to trace a leak in the gas regulator is to check it with a leakage spray.
	Diaphragm leaks along the plate rim.	Repair should be carried out by the dealer.
The ZON MARK 2 operates, but there is no explosion or sound.	Ignition gives a weak spark or no spark at all.	Check the electrode, no. 7052F. It is possible that the porcelain or the mass point is broken; if so, renew. Distance mass point - electrode: is not correct. This must be 2.5 - 3 mm. If not so, adjust with a small pair of pincers. Spark bolt, no. 7262: is loose. Turn up or down until the tripper, no. 7226, is free from the main body, no. 7112. the distance is 1 - 1.5 mm, then tighten the nut firmly. Note: The spark bolt, no. 7262, must be in horizontal contact with the piezo-element, no 7052A. Piezo-element, no. 7052: replace. Piezo-element, no. 7052A, and/or electrode, no. 7052F are wet. Dry both well.
	The wind is too strong; gas/air mixture is disturbed.	Place the ZON MARK 2 down wind or, if possible, place it out of the wind or behind a screen.
	Gas mixture is not good.	Gas mixture in the gas tank is not good, replace gas tank. Preferably use propane gas.
The ZON MARK 2 works, but the diaphragm gland, no. 7142, remains in the top position.	The gas valve-holder, no. 7042F, is blocked or partially blocked.	Clean opening with small piece of wire no morethan 0.6 mm thick.
	The gas valve, no. 7042, is not open.	With two fingers, pull up the hinged clip, no. 7042M, two or three times.
	Gas valve, no. 7042, stays open: diaphragm gland, no. 7142, remains above. The gas valve, no. 7042, can't be opened or sufficiently opened.	Torsion spring, no. 7152A and/or no. 7152B are broken. If so, replace. Lifting level must be 1 - 2 mm. The measures which have to be taken for this, must be carried out by the dealer.
The ZON MARK 2 works, but gives dull explosions.	Wind is too strong; gas/air mixture is disturbed.	Place the ZON MARK 2 down wind, or if possible, place it out of the wind or behind a screen.
	Telescopic megaphone not or partially pulled out.	Pull out to full extension.
