Gas Connection
Harmony 45 (H45)
Connect a 15mm gas supply pipe to the 3/8” connection at the rear of the appliance. We advise that a
minimum supply pipe size of 15mm is utilized, (8-10mm supply pipe is not suitable).
Harmony 35 (H35)
Bring a 15mm gas supply pipe as close as possible to the appliance connection, use an 8mm pipe for the final
connection. Do not use more than 500mm of 8mm final connecting pipe.
Connect a suitable gas pressure gauge to the test nipple on the gas valve, see page 18, turn the gas supply on
and check that the gas connections are sound. If satisfactory light the appliance. Check all the gas connections
on the appliance for leaks. The appliance is factory tested, but it is possible for a connection to have been
disturbed during transportation and installation.
Set the control to the high setting, and check that the gas pressure is as stated on the data table.
Turn off the gas, remove the pressure gauge and refit the test point screw, turn the gas supply on and check
that the test nipple is gas sound.
Lighting
For full operating instructions see operation manual.
Turn the on/off knob, smaller right hand knob, slightly counter-clockwise towards the ignition position until the
control knob stops turning, press it down and hold for 5 seconds to allow the gas to the pilot light.
After 5 seconds turn the control to the pilot position with the knob still depressed. There will be an audible click
as the Piezo spark is generated. Hold down the control knob for 30 seconds if the pilot has lit, if it has not lit
then repeat the pilot lighting procedure to maximum of 6 attempts. If after 6 attempts the pilot has not ignited
leave the appliance for 5 minutes before attempting again. (This assumes the system has been purged)
Once the pilot has been established, let out the control knob and turn it anticlockwise to the “ON” position.
