8. Instructions for the Mertik Maxitrol GV60 and the Remote Control:
Ensure that the fuel supplied to the unit is clean and free from particles and moisture.
Before a gas supply pipe (new or existing) is connected to the main gas pipe at the gas meter and to the gas
control block of the unit, clean and dry compressed air should been blown through it.
Cut copper pipes as well as aluminium pilot pipes must be deburred and blown clean before they are
connected. The dust filter at the connection to the gas control block will only filter out the coarsest dirt
from the system. Fine particles are still able to reach the inside and may damage and/or adversely affect
regulation in the gas control block .
Heat, moisture and dust are a threat to all electronic components
Protect the electronic gas control
until
all construction, plastering and paintwork has been completed. If
such work cannot be avoided, then protect the control against dirt and moisture penetration by using, for
example, plastic film .
Warning
Electronic components will become permanently faulty when exposed to temperatures higher than 60°C.
Standard AA batteries will crack open at temperatures >54°C and the battery contents will damage the
electronic switches located underneath. Batteries last longest at <25°C. At >50°C the life span is around 23
weeks, this makes the use of the gas fire unnecessarily expensive.
Only install the gas control block and receiver as pre-installed at the factory
Remember that components may have to be replaced or that repairs may have to be performed at a later
date.
This may be more difficult if the control is installed using a method that is different from the instructions
provided here.
Please note!
Only place the batteries
after
wiring to the receiver, gas control block and pilot set is connected.
Premature connection to the energy source may damage the control’s CPU (central processor).
Ensure that the ignition cable is not near the antenna wire and that they do not cross each other.
The high voltage released at ignition may damage the sensitive receiver circuit.
This may mean that the unit becomes less responsive or not responsive at all to handset commands. (See
photograph 1 on page 16)
If the manual transmitter range is too limited, loosen the antenna wire from the terminals on the
receiver box . Direct the antenna wire away from the ignition cable and in the direction of the control
box door.
Ensure there is no contact with metal components. Ensure there is no damage to the connection to
electronic components or to the wire itself. (See photograph 1 on page 16)
Connect the wires correctly to the contact breaker behind the gas control block.
The shortest wire runs immediately back to the 1/0 switch and can be found nearest to the back of the gas
control block. The longest wire runs to one of the two connections on the receiver box and only fits on one
of the screws .
Do not tighten the contact breaker and the thermocouple connection too tightly on the gas control
block or to each other.
It is sufficient to tighten by hand and add a half a turn with an open-end spanner. Tightening too much
will break the connection to the magnetic coil below and/or the insulation around the aluminium contact
pin in the contact breaker. This may lead to the magnetic coil not opening the gas supply to the pilot and
the unit not working.
