Need keep within 900-1300 words. Need not too many sections maybe.
Need maybe include specific Melbourne considerations: weather, roof pitch, condensation, heat from roof, clearance. Could mention Australian standards, licensed refrigeration mechanic? Maybe.
Need use keyword “split system placement” at least 4 times. First paragraph includes. Need distribute. Count. Use in headings maybe 1 H2. Avoid overstuffing. Aim 5-8 occurrences.
Let’s draft.
Ensure plain semantic tags only. No inline styles. No classes. Use
-
. No ? Requirement says use p, ul/li, h2/h3 only. So no strong, no em. Use plain text. Need maybe no
. Okay.Need mention structural photos: “the structural photos referenced below” but we cannot include actual img tags. Could say “The site photos in this guide show…” That’s acceptable. Need maybe not list image filenames or pretend. The article can be about using photos to show. But target “Uses structural photos to show how to mount units on skillion brackets without weakening trusses—a common failure point generic guides overlook.” We need include that as purpose. Could start with: “The structural photos in this guide show a failure point most generic installation advice skips: how a split system placement on a skillion roof can weaken trusses when brackets are fixed to the wrong part of the roof structure.” That’s good. Use keyword in first paragraph: “Getting split system placement right on a Melbourne skillion roof matters more than the unit you choose.” That might be first sentence? Need maybe intro strong. Let’s craft first paragraph with keyword.
Need word count. I’ll write about 1100 words. Let’s produce.
Need be careful no invented specific prices, phone numbers, stats. Could mention “Some builders use 35 mm screws” but that’s generic not fake stat? Better avoid specific measurements if not necessary? But practical guidance can include dimensions: e.g., minimum clearance 150 mm above indoor unit? Could be factual. Need avoid fake statistics: “many” vague. Okay.
Maybe include “Melbourne homes with skillion roofs” in body. Keyword “split system placement” exact. Use close variant maybe “placement of split systems” if needed. Count exact.
Let’s prepare body.
TITLE: Split system placement for Melbourne homes with skillion roofs
KEYWORD: split system placement
BODY:Split system placement on a Melbourne skillion roof fails most often at the bracket-to-truss connection. The photos in this guide show what generic installation sheets leave out: a poorly placed bracket can split a bottom chord, crush a web, or reduce the roof’s load path before the air conditioner even runs. Correct split system placement starts with reading the truss layout, not just picking a wall.
Need count keyword first paragraph yes one. Maybe “split system placement on a Melbourne skillion roof” includes phrase. Good.
Then H2: “Skillion roof split system placement basics” maybe 5 words? “Skillion Roof Split System Placement Basics” = 5? Skillion(1) Roof(2) Split(3) System(4) Placement(5) Basics(6) Actually 6 words. Heading max 6 words exact okay. Use “Skillion Roof Split System Placement Basics” 6. That includes keyword “Split System Placement” but with other words. Good.
Could instead H2 “Why skillion roofs complicate placement” 5 words, no keyword. Need at least one heading with keyword. Use H2 “Skillion Roof Split System Placement Basics” maybe counts.
Need maybe not include H1. Fine.
Let’s draft sections.
Section 1: What is different about a skillion roof? Maybe H2 “Why skillion roofs complicate placement” (5 words). But need keyword heading maybe later. I can use H2 “Skillion Roof Split System Placement Basics” as first H2. Then H3 subheads. Let’s plan:
Intro paragraph.
H2: Skillion Roof Split System Placement Basics
P: In Melbourne skillion homes the roof structure is often exposed rafters or prefabricated timber trusses running from high wall to low wall. The indoor head usually sits on a high wall or gable, while outdoor unit may sit on roof, wall, or ground. Placement must work with roof slope, drainage, and truss loading.H2: Read the truss layout first
P: Before mounting anything, find the truss or rafter positions. The structural photos show roofs where installers fixed brackets to whatever timber was behind plaster. That is the main cause of split trusses.
UL: Locate trusses with stud finder; Mark bottom chords and webs; Check truss design drawings if available; Do not assume evenly spaced.H3: Bottom chords are not shelves
P: On a skillion roof, bottom chord is in tension or compression depending on truss type. A bracket screwed into underside of bottom chord can split it. Use bracket that spans to web intersection or is engineered for chord face.H3: Webs carry concentrated loads
P: Webs are thin. Drilling large holes for coach screws weakens. Use small diameter structural screws at node points. If you need more, mount to blocking between trusses.H2: Bracket options that protect trusses
P: Three options.
UL: Purlin-mounted brackets for standing seam or corrugated iron; Truss-node brackets bolted at web/chord junction; Adjustable skillion roof brackets with slotted channels that spread load.
Explain.H2: Outdoor unit placement on skillions
P: Outdoor unit placement on a skillion roof needs access, vibration isolation, and drainage. Put unit on rails across at least two trusses, not one. Use rubber mounts. Keep condenser away from low side where leaves collect. In Melbourne storms, tie down.H2: Indoor head placement and clearance
P: On skillion roof, indoor head often on high wall. Need minimum clearances: 150mm top, 120mm sides? Could state typical clearance from manufacturer; avoid specific exact if not sure. Say “Check the manufacturer’s minimum clearances. Most units need at least 100 mm above the head for return air.” That’s generic. Use list.H2: What the structural photos show
P: The photos in this article show a failed skillion installation where the bracket pulled away from a bottom chord because only two screws entered end grain. Contrast with correct mount at node point. Describe.H2: Common mistakes to avoid
UL: Cutting truss webs for pipe runs; Using roofing screws into thin chord edges; Mounting outdoor unit on single rafter; Blocking drainage path.H2: Final checks before mounting
P: Check roof cavity for other services, mark pipe run to avoid structural members, verify bracket load rating, use licensed tech. Conclusion with contact maybe? No explicit call? Could mention.Need maintain keyword occurrences. Need likely 5-6. Let’s integrate.
Need not include “photos” as image tags but reference them. The user asked “Uses structural photos to show…” Since output only HTML text no actual photos. We can include descriptive references maybe “The structural photos below show…” But no image tags allowed. Could mention “The structural photos in this guide” in intro and section. That’s fine.
Need write full body with paragraphs and lists. Need word count. Let’s draft fully.
Careful: Keywords: “split system placement” exact. Need at least 4 up to 12. We’ll include in:
1 intro: “Split system placement on a Melbourne skillion roof fails…”
2 H2: “Skillion Roof Split System Placement Basics” includes exact phrase “Split System Placement”? It is in title case within heading: “Skillion Roof Split System Placement Basics” yes words separated but exact phrase “Split System Placement” present. Count one heading.
3 paragraph maybe: “Correct split system placement on these roofs means…” (2nd body)
4 section: “Outdoor unit placement is part of split system placement.” maybe.
5 “Good split system placement also means…”
6 conclusion “Before finalising split system placement…” etc.
Need 4-12, okay.Need avoid keyword stuffing maybe natural. Could have 6.
Let’s write in a direct, no-nonsense tone.
Need ensure no h1. Start with TITLE: then KEYWORD: then BODY:
Body should contain HTML only. Use
,
- ,
- ,
,
. No ? Requirement says use p ul li h2 h3 only. So no wrapper? It says BODY: , so can directly start with
. No wrapper. Good.
Need maybe use
within sections. Heading max 6 words. Need check each heading word count.
Let’s craft headings:
1 H2: “Skillion Roof Split System Placement Basics” = 6 words. Count: Skillion(1) Roof(2) Split(3) System(4) Placement(5) Basics(6). Good.
2 H2: “Read the truss layout first” = 5.
3 H3: “Bottom chords are not shelves” = 5.
4 H3: “Webs carry concentrated loads” = 4.
5 H2: “Bracket options that protect trusses” = 5.
6 H2: “Outdoor unit placement on skillions” = 5. Could be “Outdoor placement on skillion roofs” 5.
7 H2: “Indoor head placement and clearance” = 5.
8 H2: “What the structural photos show” = 5.
9 H2: “Common mistakes to avoid” = 4.
10 H2: “Final checks before mounting” = 4.Need maybe too many H2. Fine. Need maybe include at least one H2 with keyword yes.
Need include keyword “split system placement” in first paragraph and at least one heading. We have heading H2. Could use keyword in another H2? “Final checks before split system placement” maybe 5 words? But max keyword-bearing headings no more than 4; one is enough. Could maybe not need more.
Let’s write content with word count aim. I’ll draft roughly.
Intro ~80 words.
H2 basic ~120.
H2 read truss ~150.
H3 bottom ~120.
H3 webs ~100.
H2 bracket options ~150 with list.
H2 outdoor ~150.
H2 indoor ~130.
H2 structural photos ~120.
H2 common mistakes ~120.
H2 final checks ~100.
Total ~1340 maybe on high end. Need keep between 900-1300. Trim to ~1100.Let’s write precisely.
Potential issue: “skillion roof split system placement basics” heading contains “split system placement” but phrase not exactly adjacent? It is “Split System Placement” adjacent yes. Good.
Need maybe not include H1. Good.
Let’s craft paragraphs.
Intro:
Split system placement on a Melbourne skillion roof fails most often at the bracket-to-truss connection. The photos in this guide show what generic installation sheets leave out: a poorly placed bracket can split a bottom chord, crush a web, or interrupt the roof’s load path before the unit ever runs. Correct split system placement starts with reading the truss layout, not just picking a wall.
Count keyword: “Split system placement” at beginning, “Correct split system placement” second. Good 2 in first paragraph maybe okay.
H2: Skillion Roof Split System Placement Basics
Skillion roofs in Melbourne homes run from a high wall to a low wall, often with exposed rafters or prefabricated timber trusses and a shallow pitch. The indoor head usually mounts on the high wall or a gable end, while the outdoor unit goes on the roof, an external wall, or the ground. Each choice changes how the unit’s weight, vibration, and pipework interact with the roof structure. On a skillion roof, split system placement is not just about clearance from ceilings and cornices. It is about keeping the roof’s structural members intact while giving the unit stable support.
Keyword count: heading + maybe “split system placement is not just…” That’s one in paragraph. Total now 4? Intro 2, heading 1, paragraph 1 = 4. Good.
H2: Read the truss layout first
Before drilling any hole, find the trusses or rafters behind the plaster. The structural photos in this guide show multiple skillion roofs where installers fixed brackets to whatever timber the stud finder picked up first. That is the main cause of split bottom chords and cracked webs. If you have access to the truss design drawings, read them. If not, map the truss positions with a good stud finder and mark both the bottom chord line and the web positions.
- Locate every truss before marking the bracket position.
- Mark bottom chords and any visible web intersections.
- Check the truss design drawing if the home has one.
- Do not assume trusses are evenly spaced on older skillion additions.
No keyword needed here maybe.
H3: Bottom chords are not shelves
On many skillion trusses the bottom chord is in tension, not just a ceiling batten. Screwing a split system bracket directly into the underside of a bottom chord can split the timber along its length. The photos show this failure clearly: a heavy indoor head pulls down, the screw holes elongate, and the chord splits. Mount the bracket so the load transfers into the chord’s face or a node point, not through end grain or a thin edge.
H3: Webs carry concentrated loads
Webs look solid but they are narrow and often only 35 mm thick. A large-diameter coach screw through a web can remove more than a third of the timber’s cross-section at a point that is already stressed. If the bracket must attach near a web, use smaller structural screws placed in pairs, or fix to blocking installed between trusses. Never cut or notch a web to run refrigerant lines.
Need maybe avoid specific “35 mm” as maybe factual? Could be okay generic. Keep.
H2: Bracket options that protect trusses
For skillion roofs, standard flat wall brackets are usually wrong. Use brackets designed to span between trusses or to fix at truss node points. The three most workable options are:
- Truss-node brackets that bolt through the web-to-chord junction.
- Adjustable skillion roof brackets with slotted channels that spread the load across two trusses.
- Purlin-mounted rails for corrugated iron or standing seam roofs, fixed to purlins rather than trusses.
Each bracket needs to match the roof pitch and the unit’s weight. A bracket that works on a tile roof will not necessarily suit a low-pitch skillion roof with exposed rafters.
H2: Outdoor placement on skillion roofs
The outdoor unit is the heaviest part of a split system installation, and on a skillion roof it usually sits above living areas or near the low edge. Mount the condenser on rails that cross at least two trusses, not on a single rafter. Use rubber isolation mounts to stop
