If the actual supply voltage is higher than the voltage on the rating label (or the voltage
for which the furnace was last set), immediately after switch-on set the temperature
setpoint to zero, to prevent heating and drawing excessive current.
First select user level 2. Press and hold the page
until ‘Access Goto’ is displayed.

Exhaust Vent Connections
Note
: Significant amounts of carbon monoxide may be exhausted from
the work tube during the use of this furnace. Carbon monoxide is toxic
and inflammable (see section 1.2) it is recommended that the vent tube
is routed out of the building.
The furnace must always be positioned as recommended in section 3.4.
The furnace has two exhaust vents, the main vent at the back of the heating chamber
and a safety pressure relief vent at the side of the furnace. The purpose of the safety
vent is to prevent dangerous pressure build up as the furnace warms up if the main
vent tube becomes blocked.
The main vent and the safety pressure relief vent must be connected to separate vent
runs and routed out of the building.
With the back panel removed access is gained to the main vent tube fitting situated on
the work tube back seal assembly below the thermocouples. The main vent tube fitting
is a 12 mm x 3/8" BSP adapter suitable for connecting 12 mm diameter copper tube.
See fig 6.
The safety pressure relief vent tube fitting is a 6 mm x 1/8" BSP adapter suitable for
connecting 6 mm copper tube. See fig 11a.
Note
: It is important that the vents are not restricted in any way, do not use a tube of
less than 6 mm diameter for the safety pressure relief vent connection and 12 mm for
the main vent connection.
Check regularly that the main and safety pressure relief vents are clear from
obstructions.
