Certification · Shunde, Foshan

Water heater certifications,
filed as documents, not claimed as badges.

Gulfstone builds off-grid outdoor water heaters for importers, RV builders and outdoor brands. A certification is only worth what the buyer can read — so every certificate, letter and laboratory report behind these marks is published in full.

The file

Three markets, three schemes,
each proved by its own document.

Nothing here is one certificate stretched across three regions. Each market has its own scheme, its own standard and its own document number, issued by its own body — and each is downloadable below.

The path

A certificate is the last step,
not the first claim.

The Australian file is followed here from application to marking, because every stage of it is on this page. The other two markets run the same shape through their own bodies.

  1. 01

    Application and test programme

    The configuration is submitted and an application number is allocated. AGA set the test programme against the standard before any testing began — for this file, AGA application 20295.

  2. 02

    Independent laboratory test

    An accredited laboratory tests the submitted sample against the standard. This file was tested by CCIC-CSA International Certification Co., Ltd. in Guangzhou, accredited to ISO/IEC 17025 under accreditation number TL-464.

  3. 03

    Sample modification and re-test

    Where a test requires a change, the sample is modified and re-run rather than argued past. This file records a modified exhaust outlet and a mesh wind barrier fitted at the bottom before the tests passed.

  4. 04

    Review and certificate

    The scheme reviews the report and issues the certificate if the results stand. AGA recorded the results as satisfactory with no further assessment required, and issued certificate 9358.

  5. 05

    Production audit

    The certificate is not the end of the obligation. AGA require a Product Verification Audit — arranged when the first production batch is ready. For this file that audit is outstanding.

  6. 06

    Marking before supply

    Nothing ships before the unit carries its marks. AGA require a Maker's Warranty Badge or an AGAMark under licence, plus the Gas Compliance Mark, on every production unit.

The certifying body's condition on the mark

CSA make the certificate conditional on a production test plan run at the factory and documented for their field services representatives. These are CSA's conditions on the mark, not our own line controls — how the line itself is gated is on the quality control page.

  • Burner, manifold and control assembly — proper operationEvery unit
  • Manifold and control assembly — gas tightnessEvery unit
  • Components — regulators, valves, controlsPer batch or per month
  • Burner operating characteristicsPer 1,000 or per week
  • Ignition systems — shut-off within 30 s of flame lossPer 1,000 or per week
  • Combustion — carbon monoxide, air-freePer 1,000 or per week
  • Gas valves and carrying handlesPer 1,000 or per week

Coverage

A certificate names configurations,
not a product line.

Each document lists the model numbers it covers, by suffix that marks the market. What follows is the report's own breakdown of those numbers — the part that says what a suffix means.

Certification attaches to the configuration that was tested

Certification covers the configurations listed above and nothing else. A model outside them is not covered, and a change to a covered one re-opens the file — which is why the alterations record sits below. What applies to your order is confirmed in writing.

Our position on certification claims

The tested configuration

A live file records what changed,
and closes it.

Certification tests a specific build. When the build changes, the file records the change and the unit is re-tested before the certificate stands — including when a test fails first.

AGA · report 80247602

Sample modification

The submitted sample was recorded with a modified exhaust outlet and a mesh wind barrier at the bottom — the change the wind test required. The tests were then passed.

Resolved before issue
CSA · report 80234452

Ignition period

The delayed ignition test failed because the flame flashed out of the appliance. The ignition period was changed from 4 seconds to 1.5 seconds, and the report records the alteration.

Resolved in edition 1

Why we publish this

Every certification file accumulates notes like these. A file that shows only the passes has been summarised; this one records the change and the fix together, which is the only form in which it is useful to a buyer.

On the unit

What the certificate obliges
to be printed on the goods.

Each scheme requires its own mark before a unit may be supplied. These are the marks to look for on the article, and the markings the documents require alongside them.

Australia / New Zealand

AGA Maker's Warranty Badge or AGAMark

On every production unit, for the currency of the certification

The badge must be purchased from AGA; the AGAMark is applied under licence. Either way the Gas Compliance Mark is required as well.

North America

CSA Mark with C and US indicators

C and US for both countries, US alone for the United States, neither for Canada alone

Units certified for Canada must carry every caution and warning marking in both English and French.

Europe

CE marking

On the unit, under the directive named in the verification

The marking declares conformity with the directive the verification of conformity was issued against.

The holder's registered name appears on the certificate exactly as issued. Match the mark on the unit against the document number, not against the brand alone.

Buyer evidence

What a complete file looks like from the buyer's side

From buyers whose compliance lead read the source documents rather than a summary.

“The paperwork arrives with the goods now, instead of after them.”

Two customs clearances, neither held. We import into three markets and every one wants proof before it wants a sample — the first container carried the certificate and the report behind it, so our compliance lead read the source rather than chase us for one.

Sofia MarchettiSourcing Lead at an outdoor equipment importer
“The report listed our exact configuration by name.”

Our model's suffix matched the market it was bound for, so nothing rested on our reading of a range certificate. When we changed the build, the file recorded the change and the paperwork was updated before the next batch shipped.

Before you order

The certificate questions a buyer asks

Which document applies, what is covered, and what the file does not claim.

01Which certificate applies to the unit I order?
It depends on the destination market and the exact configuration. Each document in the file lists the model numbers it covers, and those lists do not overlap across markets — an -AU unit is covered by the Australian certificate and not by the North American one. Tell us the market and the configuration and we will confirm which document applies, in writing, before the order.
02Can I see the certificates before placing an order?
Yes — that is what this page is. Every certificate, letter and laboratory report behind the marks is published in full and downloadable, so your compliance lead can read the source documents rather than take our word for the standard.
03The laboratory report is marked Draft. Is it valid?
It is the working report the certificate was issued on, published as it stands rather than cleaned up. The certificate itself — the document that carries the mark — is the issued version and sits alongside it in the file. We publish the draft because it is the document containing the test detail, and hiding it would make the file less useful.
04Does the European verification cover the gas appliance?
No, and we state that rather than let it be assumed. The European document is a verification of conformity for a battery-operated shower system under the Low Voltage Directive, which covers electrical safety. The directive it names is printed on the document, and it should be read with that scope.
05What happens if you change something on a certified model?
The change is recorded against the certification and the affected tests are re-run before the certificate stands. Our own change-control process — how one approved sample is held as the reference for a whole run — is on the manufacturing page; this page records the changes the certification bodies themselves noted.
06Why is a production audit still outstanding on the Australian file?
Because the certificate is issued before the audit, not after it. AGA require a Product Verification Audit to be arranged when the first production batch is ready, and we would rather publish that than present a complete-looking file. It is the normal sequence, and it will be closed when the first batch runs.

The brief goes to the engineer who builds it.

Market, annual volume and the certification it must carry — three lines, and we have what we need. Your reply comes from the engineer who would run the line, scoped to your program rather than matched off a shelf.
