Refer to Table 3 for the minimum cavity dimensions and temporary lintel height measurements, until the convector box and flue system is installed.

note: Temporary lintel height is measured from finished floor protector level.

Ensure suitable air vents (min. 2 x 80mm diameter or equivalent) in place to vent firebox cavity - these maybe located in the floor or in the side wall space; make allowance (min. 2 x 80mm diameter or equivalent) at the top of the chimney chase, See Fig. 3. Ensure vents are bird and vermin proofed.

Please note that these dimensions (based on Masonry margins) are the absolute minimum sizes - widths (A & B) maybe increased if desired. If you intend on recessing the firebox, please add the recess value to Dimension ‘B’. Refer to Fig. 5

MAXIMUM RECESS = 100mm

It is important to ensure the Jetmaster gas convector is seated at the required finished floor protector level.

1. Fit and seal gather, using fire cement (exhaust cement) and bolts (supplied), to the convector box. Note:

Pop rivet back of gather to convector box if required.

2. Locate and position convector box and gather in cavity.

3. Attach rock wool to the sides & back of the convector box and gather. DO NOT BLOCK OFF the air entry

between the inner flue pipe and flue pipe casing or the air circulation between the vent holes in the cavity.

4. Drill a hole in the convector box for the Gas Line/ Wall switch cable (3m Supplied) or remove 20mm

knockout discs.

5. A minimum 300mm non combustible floor protector (hearth) is in front of the convector box. Ensure that

the base of the fire sits on the finished hearth level.

1. Install first length of flue pipe crimped end down, inside gather collar. Rivet flue pipe in 3 places around gather collar. Place bottom flue spider bracket around gather flue pipe collar, secure in position by tightening up coach bolt/screw (supplied).

2. Install second length of the flue pipe crimped end down and fix by riveting in at least 3 places around the flue pipe joint.

3. Install first length of the flue pipe casing by positioning on installed bottom flue spider bracket crimped end up.

4. Position flue spacer at the flue pipe joint.5. Repeat steps 1 - 4. As per manufacturers recommendation, the flue pipe shall extend not less than 3.6m

above the fire box.6. The flue is required to be at least 500mm above the nearest point on any part of the buildings roof and

neighbouring buildings if within a 3m radius. Refer to NZS AS/NZS 5601:2013 for further information.7. The last length of flue pipe needs to extend past the flue pipe casing by at least 150mm or flush with the

top of the casing cover spigot when fitted - sizing/measuring and cutting down should be carried out prior to the flue pipe casing being fitted over the flue pipe.

8. Before fitting casing cover, place the spider in opposition with the spider post facing down between the flue pipe and flue pipe casing. Secure spider in position. Place the casing cover over the flue pipe, press down firmly onto the spider. Check airway around the casing cover is clear, then secure in position using three stainless steel rivets.

9. Fit cowl to top of flue - DO NOT RIVET IN POSITION. In high wind areas, it is recommended that the cowl be secured in position with a stainless steel self tapping screw, this will enable the cowl to be removed for cleaning. Discuss Bird Proofing needs with your installer. N.B. in extreme wind areas it may be necessary to consult The Fireplace Ltd or your local agent for further technical assistance.

10. If flue is concealed in a chase, allow for air vents (2 x 80mm diam. or equivalent) at the highest possible point on the chimney chase or alternatively, allow a min 25mm air space between the casing cover spigot and the outer casing. Refer to Figure 7 and 8.
