WARNING
Tightness test after installation
Paint all pipe connections and gaskets with a strong
soap and water solution.
Start the appliance and check for bubbles. If a leak is
found in a pipe connection, remake the joint. A gasket
leak can usually be stopped by tightening the
mounting screws. Otherwise, replace the gasket.
Be careful not to clog bleed vent parts with soap
solution residue. Remember bleed vents will
discharge air during gas valve opening or closing
giving false indication of leakage.
ADJUSTMENTS, CHECKOUT AND
MAINTENANCE
WARNING
Adjustments must be made by qualified persons only.
If the appliance manufacturer supplies checkout and/
or service and maintenance instructions carefully
follow them.
If these instructions are not provided then use the
procedure outlined below.
Pressure tap
The combination gas control is provided with a pressure tap of
9 mm outer diameter at inlet and outlet side.
When checking the pressure undo the screw a half turn and
slip tube over nipple.
Ensure that screw is retightened after making test.
Pilot flame (VR4601/VR8601 only)
WARNING
It should be noted, that after a long time of stoppage
(summer) it can take up to 60 s to come to an ignition
of the pilot burner.
Outlet pressure adjustment (see fig. 1)
· Disconnect pressure feedback connection (if applicable)
· Energize both electric operators in order to have gas input
to burner.
· Check gas input to the appliance using a clocking gas
meter or alternatively a pressure gauge connected to the
outlet pressure tap.
· Remove cap screw to expose pressure regulator
adjustment screw.
· Slowly turn adjustment screw with a screw driver until the
burner pressure required is recorded on the pressure
gauge.
Turn adjustment screw clockwise to increase or
counter--clockwise to decrease gas pressure to the burner.
· For non--regulating mode (LP gas) turn adjustment screw
clockwise until it stops.
· Replace pressure regulator cap screw.
· Connect pressure feedback connection (if applicable).
Check of slow opening (Softlite)
The Softlite pressure is factory set.
Check burner performance at this pressure observing burner
ignition and flame characteristics. Burner should ignite
promptly and without flash back to orifice and all ports should
remain lit.
Cycle burner several times (wait 15 seconds between cycles
to allow servo system to resume slow open action).
Repeat check of slow opening after allowing the appliance to
cool down.
Checkout
Set appliance in operation after any adjustment and observe
several complete cycles to ensure that all burner components
function correctly.
Maitenance and service
Under normal circumstances no maintenance or service is
required. Screws on the valve that have been sealed must
never be removed.
