How to plan kitchen fire suppression in Ontario.

Get the cooking line clear before buying a system.

If you are taking over a restaurant, the hood and suppression equipment may already be there. If you are starting from an empty unit, they may be separate lines in a construction quote. Either way, the useful first question is the same: what equipment will this kitchen actually use, and where will it sit?

A hood length on its own does not describe the whole job. Put the appliance list, proposed layout, hood information and any existing system records in front of a qualified suppression specialist. Have the specialist confirm what can stay, what needs to change and how the work connects to the rest of the build.

You do not need a complete drawing set to start a conversation. An address, a few clear photos and a list of the equipment you intend to use are a useful beginning.

When does a kitchen need fire suppression?

Ontario's Fire Code connects cooking operations that produce smoke or grease-laden vapours to exhaust and fire protection requirements under NFPA 96. The regulation includes exceptions and provisions for approved existing systems; a hood or an old service tag alone does not establish that your proposed operation meets the requirements.

Ask your design professional and suppression specialist to confirm the requirements for the actual menu, appliances, layout and address, together with the local reviewing authority. If you are also changing the room or building systems, review the commercial kitchen permit planning guide.

Can you keep the existing suppression system?

Possibly. Have it assessed against the cooking line you plan to operate. Keep the existing drawings, service reports and equipment information together, and show the specialist what you intend to add, remove or move.

For example, replacing a cooking appliance or rearranging the line is a reason to ask for a coverage review before the change. ANSUL's R-102 owner's guide specifically directs owners to contact their trained, authorized distributor before changing the equipment layout or protected area.

Let the specialist assess and make any system changes. Leave the nozzles, detection components and releasing equipment to them.

Send enough information to price the same job.

Tell the team whether this is a new kitchen, a renovation, a change to the cooking line or a request to assess an existing system. Then share what you have:

• The project address, current use and target opening or renovation date
• The cooking-equipment list, including model numbers and proposed positions
• Hood dimensions, available specifications and photos of the cooking line
• Existing suppression drawings, system identification and service reports, if available
• Any landlord, insurer or authority comments already received
• Operating hours, site-access restrictions and possible shutdown windows

Ask each proposal to identify who handles design, installation, connections to other trades, submissions where required, testing and the final documents. It should also say what is excluded. A low price is difficult to assess if electrical work, appliance shutdown connections or completion documents sit outside it.

If the hood is changing too, include the exhaust and ventilation scope in the same review.

What affects the cost of kitchen fire suppression?

The appliances and their arrangement, hood configuration, existing system condition, required specialist work and connections to the rest of the kitchen all affect the scope. Access, working hours and coordination with other trades also belong in the estimate.

For a new kitchen, ask whether the price covers a complete new system. For a renovation, ask which parts of the existing installation have been assessed and which are being retained or replaced. Get those assumptions written down before comparing totals.

Once the cooking line and site information are clear, a project-specific quote is more useful than a generic price range.

Who should design, install and service it?

The proposal should name the qualified suppression specialist and any design professionals or regulated trades required for the job. Check that the specialist has the training and authorization needed for the particular system. For an ANSUL system, the manufacturer provides an authorized distributor lookup.

Commercial Kitchen Build by APEX coordinates the kitchen construction, hood interfaces and specialist scope. The proposal identifies who is responsible for the system work, testing and documentation so you know who to speak to at each stage.

How often should kitchen suppression be inspected?

For an ANSUL R-102 system, the manufacturer's owner's guide calls for an authorized distributor to inspect it at intervals of no more than 6 months, and immediately after major hood and duct cleaning. Ask your specialist to confirm the current instructions and applicable requirements for the system actually installed in your kitchen.

These are separate responsibilities to schedule: exhaust cleaning, suppression-system service and a review before the cooking layout changes. Ask who will handle each one and keep the resulting reports together.

Before handover, confirm which testing and completion records will be provided, who explains the operating procedures to your team and who will handle ongoing service. Keep that information with the kitchen's system documents.

Where the requirements and maintenance example come from.

• Ontario Fire Code, Division B, Articles 2.6.1.12–2.6.1.14: the provincial starting point for cooking-operation exhaust and fire protection.
• ANSUL R-102 owner's guide, pages 1–2: the manufacturer's instructions for this system, including layout changes and inspection intervals. The linked copy is hosted by hood manufacturer Greenheck.

Your system model, current manufacturer instructions and project requirements determine the service plan. Confirm them with the responsible specialist.
