A – Fascia attaches to the front of the firebox to finish flush with the wall
B – Your choice of pebbles, coals or logs placed into the firebox. Do not obscure the gas outlets
* C and D are only applicable if installing under bench top and or into Joinery.
C – Minimum enclosure height from top of box = 300mm
D – 1 Inlet and 1 outlet ventilation with a cross sectional area of 5000mm for each.
Minimum framing dimensions
* Note: Standard Fascia finishes flush with the bottom of the firebox so ensure a neat finish to plaster/gyprock.
Choice of firebox height
With it’s revolutionary design, the Enviro can be mounted at any height on the wall. You can choose to install the
Enviro at ground level with standard fascia or further up the wall with extended fascia.
Resting on the heath
If mounting the Enviro at floor level, it is recommended that a non combustible hearth be used for a minimum 350mm in front of the fire.
Further up the wall
Option of moving the gas inlet
To fit in with you space, the Enviro has an option to move the gas inlet from the back to the side of the heater.
Step 1– Remove round flange on bottom left side. Identify the removable panel on the left side of the heater. Unscrew the 4 screws and remove panel.
Step 2 – Using two spanners, undo the gas pipe from the main connection.
Step 3 – Remove flexible pipe from the heater.
Step 4 – Straighten flexible pipe using fingers as shown.
Step 5 – Put flexible pipe back through hole (S3) and reconnect the pipe (S2) then replace side panel (S1). Finally, replace the little round flange from the side and screw into place to cover the hole on the back panel.
Attaching the fascia
While attaching the facsia is straight forward, it is important that it remains vertical all the time to make sure the top and bottom clip in by way of clips at both the top and bottom. (Before fascia can be removed, door must be unscrewed and removed)
Minimum clearances required for balanced flue terminals or the flue terminals of outdoor appliances
(according to AS5601-2004[AGA gas installation code] or NZS 5261 [New Zealand]
a – Bellow eaves, balconies or other projections 300 mm
b – From the ground or above a balcony 300 mm
c – From a return wall or external corner 500 mm
d – From a gas meter (M) 1000 mm
e – From an electricaity meter or fuse box (P) 500 mm
f – From a drain or soil pipe 150 mm
g – Horizontal from an building structure 500 mm
h – From any other flue terminal, cowl or combustion air intake 500 mm
j – Horizontally from an openable window, door, or non-mechanical air inlet, or any other opening into a building, with the exception of sub-floor ventilations 500 mm
k –Vertically below an openable widow, door,or non-mechanical air inlet, or any other opening into a building, with the exception of sub-floor ventilation 150 mm
l – Minimum horizontal clearance to any surface (such as an exterior wall) for vertical terminations 610 mm
m Minimum height above roof line for vertical termination 600 mm
Using your flexible flue pipe
The Enviro’s revolutionary flue system incorporates one 65mm diameter pipe and one 58mm diameter pipe.
|Use 3 bends only
Our flexible flue has the ability to bend 3 times between the heating unit and the cowl. This includes the bend straight out of the heater if you’re fluing through the ceiling or floor.
|Make the flue pipe go over the bearers and joists
You may bend the flue over joists and bearers. It is recommended that a 20mm clearance be maintained between the smaller gas exhaust flue and combustible materials.
|Fluing where the pipe had a spot lower than the rest
Never allow a low spot in the flue. Installing the flue with a dip or “goose neck” can result in reduced efficiency or even prevent the fire from working.
Using up to three bends, use this triangle to work out measurements for your 4.5 mtr flue. Remember, the first bend out of the Heater is counted as one. The Enviro can be flued through the roof, wall or floor. *See your Heatmaster dealer for full details.
