INSTALLATION, ADJUSTMENT
AND CHECKOUT
IMPORTANT
Be sure the product is suitable for your application,
otherwise consult Honeywell application
engineers.
Installer must be a trained experienced service
man Turn off gas supply before starting installation.
Disconnect power supply to prevent electrical
shock and/or equipment damage.
Do not turn sealed adjustment screw, the switch
point is factory set.
Adjustments should be made by qualified
persons only.
Mounting limitations
•
VK41../VK81.. gas controls provided with gas pressure
switch gives limitations in mounting position of valve/
venturi system.
•
VK41../VK81.. gas controls with venturi system should
be provided with gas pressure switch according fig. 5.

Mounting (See fig. 6., 7. and 8.)
•
Remove pressure tap screw from the inlet pressure
tap nipple of the gas control. (if applicable).
•
Position the gas pressure switch over the inlet pressure
tap nipple of the gas control. For VK41../VK81.. gas
controls hook-up the gas pressure switch behind metal
frame of coil assembly.
•
Put the connection screw with "O"-ring into the
inlet pressure tap nipple.
•
Tighten with a 9 mm box-spanner the connection
screw with a torque of 3 Nm. When inlet pressure tap
screw (on top of connection screw) has been used,
retighten the screw 1/4 turn beyond finger tight.
CAUTION
Do not turn connection screw more tight then
specified above because of possible damage.
