Water heaters: technical submission requirements
What a reviewer expects in a water heaters technical submission on an Australian project — classified to NATSPEC worksections, not US MasterFormat.
What reviewers expect in a water heaters submission
- Product technical data for every item, keyed to the specification schedule and drawings
- Evidence of compliance with the AS/NZS standards the worksection nominates
- WaterMark certification for plumbing & drainage products, and WELS registration for water-using products, where applicable
- Shop drawings where the worksection calls for them
- Samples or prototypes when the specification requires visual approval
- Warranties and operation & maintenance information
Field tip
Confirm the exact AS/NZS standards and any WaterMark/WELS evidence the worksection nominates before you submit — a missing certificate is the most common cause of a water heaters submission being returned.
