Burner Maintenance:
Refer to the Burner Supplement supplied with the heater.
Servicing Heat Exchanger:
Heat Exchanger of multi-tube construction with removable access clean out doors
at either end. Access plates are secured by brass nuts, sandwiching glass wool
webbing type gasket material between the heat exchanger flange and the access
doors. When removing the doors it is important to inspect the gasket material and
replace if necessary.
It is important that the tubes should be inspected and swept out if necessary,
replacing Gasket Material – the material is of glass wool webbing 25mm x 3mm
thick in strip form. The method of securing it is to have strips overlapping, and to
cut through both surfaces with a sharp knife to give an exact join. Self adhesive
webbing is easier to secure (available from BMM Heaters).
