All Hebel Block margins have been made to fit firebox timber frame trim out dimensions (see Table 2).
Suggested method to cut Hebel Block - skill saw fitted with masonry blade.
Under no circumstance is the width of the vertical margin legs to be less than 90mm and the height of the
margin lintel to be less than 300mm (see Fig 5).
Where an internal wall board finish is required around the fire, ensure allowance is made to place non-combustible
internal wall lining (eg: Promina, Supalux, Eterpan) to cover the extent of the Hebel panel surround (shown shaded).
Directly touching the firebox with any board or plaster finish will cause cracking from heat expansion. Allow 2mm
minimum space away from the firebox.

1. All dimensions shown for the framing trim out and metal heat shields, are based on a maximum frontal clearance
between the timber framing and the rear of the firebox fascia, being not more than 15mm.
2. Locate floor protector in trim out cavity. If on a concrete floor, suggest a mortar screed to the underside of the floor
protector. If on a wooden floor, screw or dynabolt in place.
3. Locate stud openings on both sides.
4. Position and ensure a strip of glass rock wool insulation is between the inner hebel leg face and the firebox. Nail
through stud into hebel leg to secure in place.
5. Locate and position firebox, fit and seal gather in cavity (refer to Cross Section). Earthquake restraints may be
positioned by drilling through firebox into the floor protector, in a position midway beneath the log-pan. Two 12mm
dynabolts or similar will suffice. Do not over tighten and deform firebox.
6. Attach rock wool to the sides & back of the firebox 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.
7. Once the flue system is installed, place a minimum 300mm hebel block over the top of the firebox (see Fig. 8).
Ensure the hebel block does not rest on top of the firebox. A Lintel Bar may be required.

Refer to the minimum framing dimensions as per table 2. Allow a temporary lintel height (see table 2 ‘B’) from the
finished floor protector level until the firebox and flue system is installed. Install front nogs on edge to increase chimney
chase dimension.
Ensure suitable air vents (2 x 80mm diameter or equivalent) in place to vent firebox space - these maybe located in the
floor or in the side wall space. Ensure vents must be bird and vermin proofed.
Note: Wood Installations can be converted to Gas at a later date. or have a gas ignition system fitted. Consider running
a gas supply to firebox cavity at the time of construction.

FIREBOX INSTALLATION
CAVITY / FRAMING PREPARATION 5.TW.1D

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 to the required flue height. As per AS/NZS2918:2001 4.9.1
a. “the flue pipe shall extend not less than 4.6m above the top floor protector”.
b. “the minimum height of the flue system within 3m distance from the highest point of the roof shall be
600mm above that point”.
c. “the minimum height of a flue system further than 3m from the highest point of the roof shall be” a minimum
“1000mm above roof penetration”.
d. “no part of any building lies in or above a circular area described by a horizontal radius of 3m about the flue
system exit”.
6. 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.
7. 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.
8. 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 Ph: 0800 843 3473.
9. 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 12, 13, 14.

The Fireplace Ltd specifies that allowances MUST be made for air replacement vents to be located near the fireplace,
to aid combustion and reduce the incidence of back venting. Refer below for air vent sizing and suggested location.
Fig. 19 - Location points A,B,C,D are suggested combinations. A minimum of one pair of air vents is recommended
or one large vent, as per location point D. Allowance to be made for minimum 2 inlet ducts from outside to internal vent
location.
Note: DO NOT USE FIREPLACE CAVITY VENTILATION AS A METHOD OF AIR REPLACEMENT.
