Is there any safety procedure for damper operation in the furnace? Specially in case of failure of damper wire. Is it necessary to keep provision 100% opening in case of damper wire failure?

There will be fail safe interlock for all Automatic controlled damper to open fully whenever there is a malfunction is sensed. Still if you feel the damper malfunction is frequent, keep it manual 100% and review your interlock settings.

Yes, the damper fail safe position is full open. This is to avoid any over pressurization of radiant box incase of damper failure/damper instrumentation failure.
