Floor protector requirements
Metro fireplace inserts are designed to be installed direct
onto a concrete base. An insulated floor protector is required
to project in front of the Metro and must extend a minimum
of 200mm to each side of the door opening, making the
minimum floor protector width 825mm. The minimum floor
protector projection forward of the Metro is dependant on the
height of the fireplace insert above the combustible floor. The
following schedule of floor protector projections is measured from behind the Metro fascia being the total floor protector
depth as shown in Diagram 4 below. Note, the heights
specified above the combustible floor can be achieved by: -
• The thickness of the floor protector
• Or by raising the fireplace insert
• Or a combination of the two
Wetbacks
The Metro LTD Insert can be fitted with either of Pioneer’s 3kW
or 4kW wetback option. Only Pioneer’s cast jacket wetback
system as illustrated on page 9 of this manual should be fitted
to a Metro. Alternative wetbacks will void the Metro’s emission
approvals and may seriously effect the performance of the
appliance and will void the owners warranty.
Both 3kW and 4kW wetback options can be fitted to either side
of the firebox, with the connection pipe heights illustrated in
Diagram 4 above, please note: -
• It is recommended the return pipe has a minimum rise of
1 in 12. Performance will reduce as the distance to the
storage cylinder increases.
• The wetback must be connected to a vented system. To fit
the wetback proceed as follows: -
1. Remove the brick from the inside of the firebox from the
side the wetback is to be fitted too.
2. Expose the holes in the firebox through which the
connection pipes will pass.
The LTD Insert has a 3mm pressed washer covering these
two openings and two 6mm bolts which are fitted inside
the firebox near the connection holes, remove these also.
3. Using a hole saw or snips, prepare the cabinet for the
connection pipes. Note, these holes should be a neat
fit or have any excess gap covered or filled with high
temperature insulation.
4. Using the tube of sealant supplied with the wetback, apply
a liberal bead of sealant around both connection holes on
the inside of the firebox. On the rear of the wetback casting
apply the remaining contents of the tube equally around
both connection pipes and also the outer circumference
of the wetback which will face the inside rear wall of the
firebox. This will completely seal the wetback to the inside
rear wall of the fire on installation.
5. Fit the wetback into the firebox and position the connection
pipes through the connection holes in the firebox.
6. Fit two bolts through the slots provided in the wetback, align
the wetback so its front edge is parallel to the door opening
& secure the bolts. The wetback is ready for connection to
the storage cylinder by a registered plumber.
