Appendix I: Carbon Monoxide Room Safety Tests Sprint Pro
Appendix I: Room Safety Test
Sprint Pro is designed to assist heating engineers to work to the BS 7967 speci-
fication for carbon monoxide room safety testing. You should refer to BS7967,
which defines the requirements, details the methods as well as the pass and fail
criteria for various types of appliances.
Room Safety test in
Sprint Pro is designed to measure the build up of carbon
monoxide levels in a room where a gas appliance is in use and record those
values each minute for the duration of the test. The CO
2
test measures for pos-
sible gas leaking into a room, or already present in a room. In addition at the
end of the test it assists the engineer (in an advisory capacity only) to determine
whether the test has passed or failed or if the results are invalid. In certain cir-
cumstances, where the results are borderline or open to interpretation, Sprint
Pro will ask the operator to decide if the test has passed or failed, and will
record the operators decision.
Please note: ultimately it is the responsibility of the operator to ensure that the test
is correctly performed to the BS 7967 specification. If the data does not support the
result or the operator suspects it is not reliable due to local conditions (such as carbon
monoxide level changes due to cigarette smoke or vehicle traffic) or incorrect, then
either the test should be repeated or the operator should seek expert advice.

Result Codes
The pass or fail result is displayed when the test completes. If the test fails a
code number is also displayed. This fail code identifies the way in which the test
failed and can help identify the cause. Also when the test completes a short
text message associated to this code is displayed in a pop-up prompt dialogue
screen, to explain the reason for failure.
