In case of destruction or damage of property by fire or tornado where the same is insured against fire or tornado, it shall be the duty of the insuring company or companies, within ten days after receiving notice thereof and upon written request, to furnish to the insured proper blanks upon which to make the required proof of such loss with full directions as to what proof is required, and if any such company fails to comply with this section the failure of the insured to make proper proof of loss prior to the suit shall be no defense to a suit upon the policy, and in all cases the insured shall have a reasonable time in which to make such proof after the blanks and directions are received: Provided, however, That the furnishing of such blanks and directions shall in no wise be construed as an admission of liability by the insuring company or companies.
