The types of appliances covered by HTR1 training and asessment includes:
- Gas fires
- Wall heaters
- Convector heaters
- Stoves, which may be open, balanced or fan assisted
- Flueless gas fires (with and without catalytic converters)
- Greenhouse heaters
The Gas Fire and Wall Heater (HTR1) course is not fuel specific and the range of appliances may be either Natural Gas (NG) or Liquefied Petroleum Gas (LPG).
Prior to taking HTR1, gas engineers will need to hold a valid appropriate core gas safety assessment and CPA1, or equivalent Gas Services N/SVQ or QCF qualification. The core assessment is determined by the fuel supplied and the type of dwelling where the appliance is fitted, for example:
- NG wall heater or gas fire fitted in a house, flat or bungalow = CCN1
- LPG wall heater or gas fire fitted in a house, flat or bungalow = CCLP1 (PD)
- LPG gas fire fitted in a Residential Park Home = CCLP1 (RPH)
HTR1 is designed to assess the competence of a gas engineer to install, exchange, commission, disconnect, service, carry out repairs and attend to breakdown of appliances. However, as with all ACS assessments, HTR1 will only assess an engineer’s competence in matters of gas safety, it will not assess other key skills such as building works or electrical installation etc.
Due to the range of appliances and work activity covered by HTR1, during assessment gas engineers must be able to correctly identify the appliance type, apply the guidance given in the manufactures instructions and appropriate British Standard, and ensure that the appliance is safe to use.
Typical HTR1 training, for an installer undertaking this module for the first time, will include:
- Installing and commission an appliance
- Attending to breakdown and diagnosing gas safety faults
- Carrying out a service and identifying any installation or component defects
In addition to the practical HTR1 assessment, a number of underpinning knowledge questions covering the requirements of British Standards (BS) 5871 parts 1 – 4 must be answered correctly. Gas engineers undertaking HTR1 as a reassessment are not required to carry out the installation element and will answer fewer knowledge questions.
