Masport Inbuilt Gas Fires - 12 - 19/11/04
12. Assemble sufficient lengths of flue heat shield (150
mm dia.) so that the flue will extend the necessary
height above the roof line. (See flue instructions).
13. Lower the flue shield down through the roof
aperture until it is resting on top of the outer steel
case. Check from below that it is centralised on the
hole in the cabinet and flash the shield at roof level.
14. Fasten a seismic restraint bracket on each side of
the firebox cabinet.
15. Slide the firebox cabinet into the outer cabinet and
secure the seismic restraint brackets to the cabinet
flanges.
16. Make the gas connection as detailed on Page 7.
17. Fold the flow spreader plate along the line of the
slots, with the two mounting lugs facing toward each
other until the distance between the mounting holes
is 116mm.
18. Slide out the top front section of the firebox
cabinet (not the ZC cabinet). Attach the V-shaped
spreader plate under this component, making sure
that the point of the ‘V’ will be toward the flue.
19. Place the 200mm square plate (with the 108mm
diameter hole) over the flue spigot on top of the
firebox cabinet (not the outer cabinet).
