NOTE: Built-In re clearances don’t apply in a non-combustible cavity. However, remember you will need access for servicing. The above clearance to
combustibles on the ue are only applicable within the re envelope. Clearance outside this e.g.at a ceiling / wall thimble reverts to 25mm as per ARS ue test
05/1185. Correct as at November 2011. # Fire hearth width indicative only. Critical measurement is “O”, extending in front of the re. Hearth width only needs to
be same as re width.
* from shielded ue
Note: AS/NZS 2918
requires a minimum
of 100mm clearance
for any side requiring
access.

Location of the Pellet Fire
Installation of the Enviro Classic Wood Pellet Burning Heater should be undertaken by an
experienced installer. Please read the Classic Owners/Technical Manual thoroughly before
commencing installation as failure to follow the instruction could cause damage to the pellet
re or property.
Positioning the re:
Generally the Classic should be installed in a centrally located position within the home. When
deciding where to position the appliance in your room you need to consider the following:
• Location of a power source
• The Classic has a convection fan which blows air through tubes in the direction that the
re faces, for optimum performance this location should be in a large room centrally
located.
• The Classic must be installed on a non-combustible surface. This surface must protrude
150mm from the front of the closed pellet re door.
• The Classic has been Safety Tested to AS/NZS 2918 using the Davins manufactured
ue. Test Report ARS 05/1185. Installation is not exclusive to these nominated kits,
though alternative ue should only be considered following consultation with your local
council.
• Please consult page 3 for the required clearances to combustible material also ensure
the position of structural elements near the proposed ue.
• Because of the positive pressure in the ue, sealing of all 75mm stainless joints is
mandatory – use high temperature sealant. Both inner and outer ue joints must be
riveted.
• Seismic Restraint: Please see page 9 for requirements.
• Warranty: To validate warranty following installation a copy of the completed Warranty
Registration Form/Producer’s Statement must be forwarded to: Switch - Fax (03) 341
8057.
