Found furnace intermittently throwing an A13 error on light off causing system to go out on lockout. Removed and cleaned burners, adjusted gas pressure, checked temperature differential and cycled to check operation. System now lights consistently everytime and across all 5 burners. Believe system could benefit from a new set of burners next fall and a tune up after burner replacement to check the fire rate of the furnace. Will order burners for fall tune up. Set up wifi redlink gate way and app to thermostat. Ethernet splitter did not work to adapt to the router. Recommend router switch to make more available dedicated Ethernet ports. Will order router switch to follow up on complete install of gateway.
