Mantel iron
A good means of supporting the brickwork above the
hearth surround is an iron mantel: a steel angle section
(e.g. 60x60x4) or a lintel.This enables a stress-free
installation of the appliance. Fit the mantel iron as
illustrated in fig. 4, allowing min. 10 mm between the top
of the appliance and the bottom of the mantel iron.
Connecting to a chimney flue
• The interior diameter of the pipe opening is 100 mm.
• Ensure that at least 3 m. (vertical) outlet pipe, 100 mm
diameter, is connected to the appliance.
• Corrosion-proof material should be used to connect the
pipe and the chimney flue.
• The chimney must be cleaned before the heater is
installed and the flue duct tested in compliance with
national guidelines.
Connecting to the gas supply
The gas control block has a 3/8" internal thread for the
gas connection.
Use an approved connecting tap with coupling in the
supply pipe (for Belgium this must be B.G.V. approved).
In addition:
• Expel the air from the supply pipes before connecting the
appliance.
• Avoid pressure on the gas control block and the pipes.
• Check all connections for gas tightness.
Adjusting for G25 natural gas
Ex works the appliance is adjusted for use with G20
natural gas.The primary aeration of the burner tray has a
ø 6.5 mm opening.To run on G25 natural gas this must be
adjusted to a ø 5.0 mm opening and the burner pressure
should be adjusted accordingly.
• Remove the vermiculite tray.
• Remove the burner tray by unscrewing the 4 self-tapping
screws (7), (fig.5).
• Unscrew the adjusting screw (8) in the airflow regulator
(9), (figs. 6 and 7).
