PELLET FIRE INSERT VENT SYSTEM INSTALLATION
IMPORTANT NOTE TO THE INSTALLER – Pellet fire “vent systems” are pressurised at all times during the
operation of the appliance, and it is crucial that every joint in the vent system is fully sealed using suitably rated
“high temperature silicone” [Pioneer supply industrial grade RTV silicone suitable for this purpose] NOTE;
• If joints are not fully sealed ash may blow into the room.
• Prior to commencing installation ensure that;
-
A building consent has been issued for the installation.
-
You are competent and capable to carry out this installation.
- Some stainless steel components of this vent system have sharp edges, be aware!
- You have read and fully understand these instructions.
- You have a suitable flashing available which is appropriate for the chimney.
- You also have a suitable silicone for both the flashing and to seal all the joints of the vent system.
- You have checked to ensure all the components of the vent system as listed below are
included with the kit;
A - 3 x 1200mm lengths of 100mm diameter S/S vent pipe
B - 1 x 600mm length of 100mm diameter S/S vent pipe
C - 1 x 100mm S/S telescopic offset (2 piece)
D - 1 x 600mm length of 100mm S/S flexi flue bent 90 degrees one end
E - 1 x “T” piece with cap fitted [cap is removable with gasket seal]
F - 1 x 150mm diameter galvanised casing
G - 1 x Galvanised angle bracket
H - 1 x Cowl assembly
PRE INSTALLATION
All Metro Pellet Fires are tested using all applicable procedures and equipment under AS/NZS 2918:2001 when
installed in accordance with the installation and operation manual supplied with every Metro pellet fire. Prior to
installing your Metro pellet fire insert into a masonry chimney, it is important that certain clearances and other
requirements are complied with as detailed below
Chimney cavity –
The chimney should be swept, firebricks removed if necessary, and the hearth of the fireplace
checked to ensure it is level.
Floor Protector –
A floor protector must extend 531mm forward of the front of the fireplace cavity opening.
Electrical Requirements -
Ensure a 3 pin electrical outlet is installed in the chimney cavity with a suitable isolation
switch adjacent to the appliance outside the cavity in accordance with New Zealand electrical regulations; if none exists
get a qualified electrician to install one.
Important –
It is critical that the components of this Insert Pellet Fire Vent system are installed as detailed within these
instructions. This is necessary for the appliance to be moved from the chimney cavity for annual cleaning and servicing,
then reinserted without having to disconnect or alter the vent system.
INSTALLATION
1. The galvanized angle bracket supplied must be attached to the “T” Piece as a means of securing the “T” inside the
chimney cavity. This bracket has 4 sets of holes pre-punched enabling it to suit varying width chimneys. NOTE –
Most chimneys are approx 800mm wide and these instructions are based on this measurement [move the bracket
location on the “T” accordingly if the internal chimney width of your installation is more or less than 800mm]
- Place a liberal amount of silicon inside the “STRAIGHT END” of the S/S flexi flue, and fit this over the side entry of
the “T” piece. Place these two components on a flat surface and ensure the 90 degree bend “IS AT THE LEFT END
POINTING UP” and the capped end of the “T” is “FACING YOU” [as illustrated in Figure 1]. Secure the flexi flue to
the “T” using four stainless steel rivets at 90 degree spacings around the circumference of the joint.
- Now position the galvanised angle bracket in place with the 50mm fold “TO THE RIGHT FACING UP” and hanging
over the “T” by 15mm (as illustrated in figure 1).
Note – This bracket must be positioned “parallel” with the flexi flue and “JUST TOUCHING” the removable cap of the “T” piece.
Firmly secure the bracket in position with a minimum of 4 stainless rivets drilling through the appropriate pre-punched holes and/
or drill others as required.
