Commissioning and Servicing Flashcards

What is the OFTEC Technical Standard OFS T100?

Answer: The standard for oil-firing equipment installation up to 45kW — covering domestic properties

OFS T100 is the OFTEC Technical Standard covering oil-firing equipment installation in buildings of up to 45kW output. It provides detailed guidance on compliance with Building Regulations for domestic oil heating installations.

What must a technician do under OFTEC registration if they encounter work installed by another technician that does not comply with regulations?

Answer: Document the non-compliance, inform the customer, and report through appropriate OFTEC channels if safety-critical

The technician should document any non-compliance, inform the customer of the issues and risks, and if the installation poses a safety risk, report it through OFTEC's procedures. The customer should be advised to contact the original installer.

What is the purpose of the handover procedure at the end of commissioning?

Answer: To ensure the customer understands how to operate the system safely and knows what to do in an emergency

The handover includes demonstrating system operation, explaining controls, showing the emergency shut-off, leaving manufacturer instructions, discussing servicing intervals, highlighting the CO alarm importance, and providing all relevant certificates.

What is the Benchmark Scheme in relation to oil boiler commissioning?

Answer: An industry-wide scheme ensuring new boilers are properly commissioned with documented evidence

The Benchmark Scheme requires that all new domestic boiler installations are commissioned to manufacturer specifications with the results recorded on the Benchmark checklist. This is typically kept with the boiler's user manual and is checked during warranty claims.

What is the correct action if the flue gas analyser shows readings outside acceptable parameters after all adjustments?

Answer: Investigate further for underlying causes — do not leave the appliance in operation if it cannot be made safe

If acceptable readings cannot be achieved after adjustment, there is an underlying fault. Possible causes include a worn nozzle, blocked flue, cracked combustion chamber, failed heat exchanger, or contaminated fuel. The appliance should not operate until the cause is found and fixed.

What documentation should be maintained by an OFTEC registered technician for each job completed?

Answer: Job sheets, commissioning records, notification certificates, customer sign-off, and copies retained for at least 6 years

OFTEC registered technicians must maintain comprehensive records: job sheets, commissioning checklists, Building Regulations notification confirmations, customer sign-off, photographs where appropriate, and copies of all certificates. These must be retained for at least 6 years.
