PROCEDURE:
All the dryers are fitted with a 1/2in (20.95mm) “E” gas inlet. Never connect a pipe with an inner diameter
less than this.
1- Locate the Injector “D” on the left side of the valve covered by a metal plate. Unscrew the injector
until it comes out using the wrench no. 13.
2- Replace the injector with the one contained in the hanging bag.
3- Connect the gas input to the ½” “E” connection.
4- Loosen the bolt in opening “A” of the valve one turn in an anti-clockwise direction.
5- Connect the pressure gauge on opening ”A”.
6- Check the gas inlet the pressure, it must be between
8.0 (1.99) and 13.0 (3.23
) in wc (kPa)
7- Remove the manometer pipe
8- Tighten bolt “A”
9- Loosen the bolt in opening "B" of the valve one turn in an anti-clockwise direction.
10- Connect the pressure gauge on opening "B".
11- Remove the solenoid valve plug "C".
12- Regulate the gas inlet screw "C" until the required pressure is reached according to the table on
page 22. Do not over-tighten the Nylon bolt as there is a risk of breaking the internal spring and
causing fuel leaks.
13- Replace the solenoid valve plug "C".
14- Remove the manometer pipe.
15- Tighten bolt "B".
16- IMPORTANT: on 25,35 Lb models, when a gas change is made, it is
NOT
necessary to remove
the Venturi. (view image)
