Fitting The Firebox With A Jetmaster Gather
The fitting of the firebox with the Jetmaster gather is similar to that when fitting with a concrete
gather. However, the recess must be high enough to allow the fire, and the Jetmaster gather to
be slid into position. This will involve breaking into the front of the chimney breast.
Place the fire with the gather attached in front of the prepared opening. Wrap the sides and back
of the fire/gather with the insulation and hold this in place with tape.
Slide the fire/gather into position in the prepared recess, taking care not to snag the insulation
on the sides of the opening. Once in situ then the adaptor can be joined to the flue. See section:-
Installation Using The Jetmaster Flue Gather And Adaptors. The front of the chimney-breast can
then be infilled and the cavity around the gather may be wrapped with flexible insulation or back
filled with vermiculite cement. Use strips of insulation as expansion joints where necessary.
A tight and effective seal must be made all round the front of the firebox. The box can be
sealed using the insulation supplied, in a similar manner to that Without a Jetmaster Gather. If
the front of the fire is not sealed, air could leak into the flue and chimney performance will be
impaired. The object is to form a dry seal that will stay flexible moving with the box as it expands
and contracts, yet still keep the firebox sealed. It will also help against the possibility of curing
paint fumes escaping into the room.
