Figure 17: Conversion from one gas to another
Minimum Gas Flow Adjustment
(Vented Units Only)
1. Set the control into low re setting by turning the motor knob to
OFF position and back until the valve opens.
2. The minimum rate can be set either by screwing in a calibrated
minimum rate screw (xed orice) or an adjustable minimum
rate screw. Controls with adjustable screws without a custom-
er specic setting are factory set at maximum ow.
3. Turn the screw clockwise
to decrease the minimum ow.
4. Care should be taken to screw the xed orice until it stops.
5. Close pressure tap(s) by turning the screw(s) full clockwise
. Check all connections / pressure tap(s) for leaks.
Changing the Fuel Type
(Vented Units Only; see “Convertible Pressure Regulator”)
GV60 can be converted to meet the manufacturer’s require-
ments for a specic gas type. Adjustments of pressure regulator,
minimum rate and pilot gas are according to above-mentioned
instructions. To convert for LPG CE it is necessary to block the
pressure regulator by turning the regulator adjustment screw
fully to the bottom limit (or the throttle adjustment screw fully to
the upper limit).
FINAL CHECK
Observe several complete ON / OFF cycles to ensure proper op-
eration. During these cycles the electronics will determine the
optimum ignition sequence timing.
1. STOP! Read the safety information included before proceeding.
2. Turn main valve knob to the OFF, full clockwise
position.
3. Place ON / OFF switch (if equipped) to the O (OFF) position.
4. Wait a minimum of ve (5) minutes to clear out any gas. Verify
that no gas is in the area around the appliance, including near
the oor. If you detect gas STOP! Follow “What to do if you
smell gas” in the safety information (see page 2). If no gas
is present, proceed according to the Mertik Maxitrol Operating
Instructions.
Fire or Explosion Hazard. Attempted disassembly or repair
can cause property damage, severe injury or death. Do not dis-
assemble the gas valve; it contains no serviceable components.
MANUAL OPERATION
(Only possible, when MANUAL knob is used)
Access to the pilot burner is only required for ignition with a
match.
When turning main valve knob, do not force. Knob has a slip
clutch that clicks until the end stops are reached. This allows for
manual ame height adjustment as well as adjustment to pilot-
Standby position.
1. STOP! Read the safety information included before proceeding.
2. Turn main valve knob to the OFF, full clockwise
position.
3. Turn MANUAL knob to the MAN, full clockwise
position.
4. Place ON / OFF switch (if equipped) in O (OFF) position.
5. Wait ve (5) minutes to clear out any gas. Verify that no gas
is in the area around the appliance, including near the oor.
If you detect gas STOP! Follow “WHAT TO DO IF YOU
SMELL GAS” in the safety information on page 2. If no gas
is present, proceed to step 6.
6. Place ON / OFF switch (if equipped) in I (ON) position.
7. With the MANUAL knob in MAN position a manual pilot valve
operator and piezo ignitor (optional) are accessible.
8. Fully push down manual pilot valve operator and hold in, to
start pilot gas ow (see gure 18, page 10).
Ignition with match:
Immediately light the pilot with a match, while continuing to
hold in the manual pilot valve operator for about one (1) minute
after the pilot is lit. Release manual pilot valve operator. If pilot
does not stay lit, wait ve (5) minutes and repeat.
Ignition with piezo ignitor:
Change the ignition cable from the receiver to the valve. Push
in the piezo ignitor to ignite. If pilot does not stay lit, wait ve (5)
minutes and repeat.
If the pilot does not stay lit after several tries, turn the gas
control knob (main valve knob) to OFF and proceed to step 12.
9. If applicable, replace pilot access panel before proceeding.
10. Turn MANUAL knob to the ON, full counterclockwise
position.
11. Turn main valve knob to the full ON, full counterclockwise
position.
12. If the appliance will not operate, follow the instructions TO
TURN OFF GAS TO APPLIANCE (see page 10).
