I am new to energy auditing and have a few ?'s on combustion safety tests.
I have not had the opportunity to check a gas dryer or gas furnace (have done 2 homes with sealed burners)
1 Do I need to test draft pressure on a furnace with a draft inducer motor?
2 Are you supposed to drill into double walled vent pipe?
3 Are you supposed to open a gas dryer to check for co and if so where do you check it?
4 Where should I be checking for co in a gas furnace?
5 Do I need to test draft on a gas clothes dryer?
Thanks for any help you can give
