fit bars to the low sections of the comb first by seating the ends marked ’L’
onto the low part of the comb, whilst the ends marked ’H’ should then be
seated on the high sections. (See Fig. 2, below)
5.5 Connecting the spigot outlet to the flue system
The flue pipe must be fitted inside the outlet spigot as shown in Fig. 3 adjacent
page. Failure to do so, could result in the spillage of condensation running
down the flue and ultimately into the firebox of the appliance.
Fire cement and glass fibre rope seal should be used to create an airtight seal
between the flue and spigot. See Fig. 3. for information.
