HEATILATOR / MANUAL VERIFICATION GATE
Before construction release
Heatilator HD42 family is a working identification only. Verify data plate and exact suffix, documents 12955 (4-14-88), 12063 (6-6-88), and installed gas equipment listing. No conceptual dimension overrides applicable manufacturer clearances, service/gas access, structural backing or field measurements.
- Exact fireplace-wall width and mantel endpoint conditions
- Final forward face width/height, ceiling pitch and top scribe; 64 × 94 is existing reference
- Exact finished face depth within 12–13 in and component build-up
- Mantel thickness, elevation, window-glazing/trim conflict, finish, fabricator, structural attachment/backing and loads
- Hearth height TBD; 2 or 3 in reference only, not released; cap thickness, material, joints and support TBD
- Firebox datum, actual recession, return depth, opening transition and permitted overlap
- Heatilator data plate, exact model/suffix, installed gas equipment identification and applicable manuals/clearances
- Gas key/shutoff access, service removal paths, chimney/enclosure air spaces and circulation clearance
- Existing trim profile, height, thickness, paint and physical sample match
The appliance and chimney remain fixed. No fabricated firebox extension is approved. Confirm the exact gas equipment and listing; do not assume a particular insert from a render. Preserve glass/door removal, louvers, convection openings, lower service access and permanent gas-shutoff accessibility. Any valve or piping change requires separate qualified-trade review.
