AND CLEARANCES
If the heater is to be placed on or within 500mm of a heat sensitive floor, a floor
protector will be required. This shall consist of a continuous layer of heat resistant
material extending under the appliance to the perimeter of the protector. All joints
shall be fixed to prevent separation and shall be sealed to prevent any spilt ash or
embers contacting any heat sensitive material. Overall protector size shall be as per
diagram.
The heater and floor protector must be fixed to the floor for seismic restraint. Anchor
points are provided in the feet of the unit.

4. ASSEMBLY INSTRUCTIONS
1. Remove all packaging and timber.
2. Remove loose parts from inside the firebox.
3. Position the base with angle steel down onto the floor protector, taking the
necessary final clearance into consideration. The base has the flue centre indicated on
the flat steel bracket. The label next to this point states the minimum clearances from
the base to combustible surfaces. These measurements coincide with the figures on
page 4 for the heater clearances when assembled.
4. At this point a hole in the ceiling to accommodate the flue may be cut and the
liners installed.
5. Remove both front and rear top castings.
6. Place firebox on base. Secure with brackets provided.
7. Fit the wetback in accordance with accepted plumbing practice - please refer to
page 8. Ensure wetback is NOT pushed down; if it touches or comes in contact with
the baffle bricks this will cause wear which will void your warranty.
If NO wetback is to be fitted please ensure that blanking plugs are attached to the two
holes in the rear of the upper chamber.
8. Replace the rear top casting and refit the front top casting ensuring it fits neatly
into the rear sealed channel.
. Refit the stainless steel spigot in the top rear section of the firebox.
10. Assemble and fit flue as per instructions (page 6 & 7). Fit flue shield.
11. Place the cook top grill (which must be fitted) on the top rear casting of the fire
and secure to the rear heatshield on the fire with the bolts provided.
12. Secure the wood-burner to the floor protector for seismic restraint. DUE TO NZ
BEING AN EARTHQUAKE PRONE COUNTRY, IT IS IMPORTANT TO
ANCHOR THE FIRENZO FIRE DOWN IN CASE OF EARTH MOVEMENT.
13. Assemble and fit the decorative rails.
14. Fit handle as per drawing:
15. Fit the control knob - place the flat on the knob
to the flat on the air control shaft situated on the right
hand side of the fire. Press home firmly.

Flue components should be made of 304 or 316 grade stainless steel or vitreous
enamel and approved 150mm diameter as per NZ standards 2 18:2001, with reference
to clearances with a flue shield. A flue shield must consist of a minimum of 180
degree stainless steel, which shields the rear section of the first length of flue. A 360
degree flue shield is available which has a 180 degree mesh front for good looks.
Flues should be regularly checked for leaks and cleaned on a yearly basis (see page
11).
