Assembly Instructions

Step 1: Assemble the Stand
1.1 Start by making the two side end frames for the stand first. For each end, you will use 2 x Stand Horizontal Short Brackets and 2 x Stand Vertical Brackets. Lay them out as seen in the image below. 1.2 Line up the corners by aligning the holes with the wider fold in the leg and use the 8 x SelfTapping Screws on each hole.
1.3 Repeat for the opposite side. You should have 2 x Stand Sides. 1.4 Now you can join the two Stand Sides with the four Stand Horizontal Long Brackets. You can line them up with the Long Brackets go on the outside of each corner. Start by lining up one side first, then move to the other side. 1.5 You will then need 16 x Self-Tapping Screws, to join everything and make the stand. Note that the Bottom Tabs in the stand can also be used to fix the frame to the floor. Ensure the base is secured to the floor, using fixings appropriate for the flooring structure. The floor must be able to support the weight of the heater, flue, and fuel load, which is approximately 300kg. Refer to Step 2.2, to see how the Tabs can be bent out. 1.6 This concludes the assembly for the Stand, and you can now prepare for the assembly of the Zero Box. You will begin assembly with the stand, so if you haven’t secured your stand down, we suggest you move it close to where the unit will be installed with the Zero Box, if you haven’t so already, as the Zero Box can be quite heavy to move around.
Step 2: Attaching the Stand to the Zero Box
2.1 Place the Bottom Panel, on top of the completed Stand. The front of the bottom panel should be flat in line with the front stand face. 2.2 Flip up the Top Tabs to stop the Bottom Plate from moving around. Ensure you do this on both sides, there should be a total of four Top Tabs. 2.3 Once the front is lined up and the tabs are bent up, secure the Bottom Plate to the Stand  by using 6 x Self Tapping Screws.
2.4 You can then add the 3 x Bottom Brackets to the fixed Bottom Panel. Line them up with each hole on the Bottom Panel, and then use 4 x Self Tapping Screws on each Bottom Bracket (A total of 12 x Self Tapping Screws). Note that each of the Bottom Brackets should sit under the Front Fold of the Bottom Panel.2.5 Grab either the RHS/LHS Side Panel, and slot it into the appropriate sides. This is indicated with the circle cut-outs on each Side Panel, which should be on the bottom side, and the three-fold edge should be on the front side. Note the Side Panels should be placed on the inside of the Bottom Panel.2.6 Screw the lined-up holes for the RHS/LHS Side Panel as shown below, you will need 5 x Self Tapping Screws for one side (A total of 10 x Self Tapping Screws). Repeat this step for the opposite side. Note only fully tighten the screws once the top is in position. 2.7 Slide the Back Panel into the inside of the Side Panels and Bottom Panel. 2.8 Line up the holes and use 9 x Self Tapping Screws. Use the circle cut-outs in the Back Panel to pull the sheet towards you, which should help when you are inserting the Self Tapping Screws. Again, don’t tighten the Self Tapping Screws until the Top Panel has been placed. 2.9 You can now place the Top Panel on the top. All the folds should sit on the outside of the Side Panels and the Back Panel. 2.10 The holes should line up on The Top Panel, with the Side Panels and Back Panel. Then use 5 x Self Tapping Screws for the sides (A total of 10 x Self Tapping Screws) and 3 x Self Tapping Screws). If you are installing for the Silva 800, then go to Step 4 before continuing. Once the Top Panel is on, tighten all the screws. 2.11 You can then add the Back Bracket to the Back Panel. The heater will stop when inserted up to the Back Bracket. Use 4 x Self Tapping Screws to attach the Back Bracket. Step 3: Fitting the Flue
3.1 The flue should be raised off the top of the Zero Clearance Box, using the 2 x Flue Brackets. The Flue Brackets are fixed to the 200mm Flue (Inner Casing), and the upper folded ushaped hook is fixed to the 300mm Flue (Outer Casing). You will need 3 x Self Tapping Screws for each Flue Bracket (A total of 6 x Self Tapping Screws). The 200mm Flue slides through the top of the Zero Clearance Box and sits above the heater resting on the Flue Brackets. The 200mm Flue must be sealed with a flexible sealant around the top of the Zero Clearance Box, to stop heater air from coming into the chimney chase cavity. The 300mm Flue must sit 65mm above the top of the Zero Clearance Box.

Step 4: Converting SILVER 1000 to SILVER 800
4.1 If you are installing the Silver 1000, then you are completed with assembly. If you are installing for the Silver 800, you will need to assemble the 2 x Side Fill-Ins before tightening the Top and Side Panels. There are four slots for each Side Fill-In, at the top and bottom.Completed Zero Clearance Box with Stand for Lacunza Silver 800/1000
